Roof Types

Different types of roof have different slopes within the same building. Many traditional buildings incorporate different types of roof within a single composition. For example, a building with the primary mass under a hip may have a central projecting bay with a gable end and a front portico with a pediment. The type and shape of the roof on your home can help determine how well it will perform during a severe windstorm. Don't use the same pitch for each roof! Each type has its own characteristics and should have different slopes:
Gable Roof:
The gable roof is a very popular type of roof. The gable roof is easy to build, sheds water well, provides for ventilation, and is applicable to a variety of house shapes and designs. A gabled roof has two slopes that come together to form a ridge or a peak at the top, each end looks like the letter A. Homes with gabled roofs are more likely to suffer greater damage, such as collapse of the end wall from high winds because they are often not braced properly during construction.
Hip Roof:
The hip roof is slightly more difficult to build than a gable roof, but is still a popular choice. A hipped roof is one that slopes upward from all sides of the building. Because of its aerodynamic properties and construction techniques, most hipped roofs will perform better in windstorms than the second roof type: a gabled roof. It does not provide for ventilation as well as some other roof designs and increases the chance for leakage due to the hips and valleys.
A-frame Roof:
The A-frame provides not only a roof but the walls as well. Originally, it was used for cottages, but in recent years has been applied to homes, churches, and other structures.
Flat Roof:
A flat roof is the most economical roof to build, but does not add much to the design of most houses. It requires a "built-up roof covering rather than conventional shingles. A built-up roof consists of layers of roofing, felt, tar topped with gravel. Actually, most so-called flat roofs are pitched 1/8 to 1/2 in per foot to aid in drainage. The flat roof is popular in warmer areas of the country where wide overhangs are desirable for shade and where little or no snow falls.

Roof Coatings And Their Benefits

A monolithic and fully adhered liquid that is applied over the roofs is called roof coating. It is applied over the regular roof system. That is why it acts as a covering or a top layer over the traditional roof. This asks for many features that a roof coating must possess. As it is the outermost layer therefore it is also the most exposed layer.

That is why, it is manufactured in such a way that it is able to tolerate a lot of environmental factors like UV and infrared, temperature extremities like rain, hail and the physical damage caused due to these factors. It is very elastic in nature which enables it to endure the temperature extremities without cracking. Hence roof coatings if applied properly over the roofs can provide maximal protection to the roof from these deteriorating factors, ultimately extending the life of the roof.

The advantages that roof coatings deliver cannot be ignored. The foremost benefit is repairing roof leaks. In this way it reduces the cost of re roofing. In addition the reflective nature of roof coatings greatly reduces the cooling cost because these coatings reflect the heat and sun rays, generating a cooling effect. Also these coatings are sometimes used ornamentally. Where roofs are exposed and visible, the roof coatings results in providing a cosmetic effect.

Among many types of roof coatings which are available, the most common ones are polymer-modified acrylic elastomers and polyureas, asphalt cutbacks and emulsions, silicones, SPF and high-performance urethanes. White roof coatings, tinted roof coatings, elastomeric, aluminum and metal roof coatings are also few broad categories of roof coatings.

Elastomeric roof coatings are very versatile and can be applied on a large variety of roofs such as single-ply, metal, asphalt, polyurethane foam or concrete roofs (CSPE, EPDM, TPO, PVC). This compatibility feature is very useful and makes it prominent among other roof coatings. An elastomeric roof coating creates a uniform, seamless and durable surface that remains flexible even at low temperatures. It is very adhesive in nature and provides excellent UV protection for polyurethane foam. Its highly reflective nature not only reduces the cooling costs but also prevents premature degradation. Elastomeric coatings can be employed both in construction phase and the maintenance phase.

Waterproofing Fish Ponds, Fountains With Liquid Roof

Liquid roof or Liquid rubber, being Liquid EPDM, has a wide range of application areas due to its extensive features. Its reflective nature results in delivering cooling effect. It is UV and ozone layer stable, highly chemical resistant, can tolerate a very broad temperature range and is compatible with a variety of surfaces like rubber, fiberglass, concrete, metal, foam, wood and fabric. It is the best solution for roof leaks repair. But besides all these features, one characteristic of epdm that is very important and must be mentioned is its water proofing nature. Due to this, it is extensively used to waterproof fountains and fish ponds.

The fountains and fish ponds have concrete surfaces. When special additives for water resistance are not added to a concrete surface, a need for an impervious coating becomes very essential. Because if such a coating is not applied, then it may lead to leaching out of soluble constituents and this is something very dangerous. These factors demand that the ponds and fountains must be glazed with a coating that is nontoxic and safe for the fishes and offers maximum water resistance. Liquid EPDM rubber, no doubt is the best. It provides protection to the surface both against the fresh and salt water.

Besides providing the water proofing feature, it also provides a solution to the roof leaks problem. The pond surface is usually plastic, concrete or rubber lined. When leaks are encountered in concrete surfaces, rubber liners are usually installed. But this process is very tricky and complicated. Also plastic pond liners generally get cracked. They can be repaired with products like caulks and tapes but they eventually get wear out. So for fixing leaks on both plastic and concrete surfaces, liquid roof is the most recommended product. It is both long lasting and easy to install.

Surface preparation for application of Liquid roof to ponds and fountains etc should be done carefully. The surface should be cleaned properly before application. If an alga is present treat with an algaecide or 25% solution of bleach, let stand for one hour and rise well. In fish ponds polishing the surface with a wire brush or a high pressure water spray might be needed. A rain free one week is needed for the surface to dry out.

EPDM Coatings Facts.

EPDM Rubber has had a long history of superior performance in hoses, molded products, tires and roofing membranes. For example, the radiator hoses in our cars and the gaskets on our freezer doors are made of EPDM rubber and show the broad temperature range the product can handle. EPDM Roofing Membranes also have more than 30 years of successful history.

EPDM is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional materials. There are not the strong odors and fumes either. The product is very stable and the resulting characteristics of Liquid EPDM such as flexibility, weatherability and chemical resistance are determined by it.

EPDM roofs are suitable for most types of facilities, offer various mil thicknesses, and can be purchased in either black or white. It should be noted that the solar reflectivity of a black roof is only 8%, which is a major factor in the Sun Belt.

Drawbacks of EPDM roofs include vulnerability to physical abuse; lack of layer redundancy; temperature sensitivity of adhesion points and sealing tape used for seams; and poor resistance to chemicals, cooking fats, and greases. As noted earlier, these roof systems don't always meet local wind uplift code requirements.

Liquid Roof Application Tips

When you want to apply liquid rubber on your roof, keep in mind that it is a 3 to 6 hrs process, excluding the surface preparation time. Once the Liquid EPDM Rubber is applied, it takes around 16 to 20 hours to dry up. Therefore careful planning should be done taking into consideration the weather conditions as well, i.e. one should plan to work on days when the rain is not expected because although Liquid Roof will immediately waterproof, even when wet, avoid heavy rain until it is completely dry to the touch which means 16 - 20 hours after application. To be on the safe side, one can say that a full cure will be achieved in 4 - 10 days after application, in consistent 70 deg. F.

A lot of liquid coatings can be seen in market but when we talk of liquid roof, its spray and application characteristics are found to be very unique and different from the other coatings. Before applying the liquid rubber, comes the surface preparation which is also a mandatory step. Surface preparation and cleaning is done to make sure that there are no holes, gaps, seams and tears on the roof and if there, they should be repaired before application. Also any potential weak areas should be reinforced and asphalts or silicone type of caulking on the roof/surface should be removed as well. The roof should be thoroughly dried prior to applying Liquid Rubber EPDM after cleaning.

Although Liquid Rubber Sealant Coating has a heavy consistency, it will self level and penetrate small crevices and pores. However before applying, catalyzing the liquid rubber with a pre-measured catalyst according to instructions is very important. The liquid roof can be sprayed or even applied with a paint brush to areas which are small and difficult to access e.g. chimneys, roof flashing, pipes, fish ponds etc. A squeegee and a roller can also be employed specially for flat surfaces where the usual practice is to pour the material, spreading with a squeegee and then leveling it with a short nap roller. Also a single application is recommended rather than applying multiple coats. For obtaining efficient results, a 20 mil layer of the liquid roof should be applied.

Roof Coatings for Flat Roofs

Coating a Flat roof for roof leaks repair was not that easy. If you have a flat roof, roof coatings help ensure that you are maximizing the most potential from your roof. Coatings are typically used to help make certain that your roof is waterproof, but today’s choice of roof coatings offers much more. Now, roof coatings can help deflect the rays of the sun and reduce cooling costs greatly. Using a roof coating can delay the need for replacing your roof and is much easier to install as well. If you are in need of roof repairs, you may want to consider contacting a professional roofing contractor and inquiring about a roof coating estimate.

Homeowners have found that if their roof need a coating for repairing roof leaks, that the cost of the coating is much less than it would be to replace the roof. Therefore, it is always a good idea to find out if this is an option before choosing to have your roof replaced. Also, check with the roofer and check out what the warranty terms that they are offering with the roof coating. In addition to the roofer’s warranty, the coating may also come with a roofing manufacturer’s warranty so be sure to find out before purchasing.
Roof coatings can also help repair and seal leaks that occur in the roof. Because the coatings are extremely durable, they tend to last for a long time, making the results near permanent.

These Roof Coatings include EPDM, Liquid Rubber and Liquid Roof. All these are roof coatings and can be use to repair Flat, metal, concrete and RV roofs beside Elastomeric roof coatings are also their for uper coat. Elastomeric roof coatings provide UV resistance and long lasting repair. If you are interested in choosing roof coatings that will help deflect the sun’s rays or help insulate your home, you should ask your local roofer about coatings that have the energy efficiency recommendation.

RV Roof Repair with EPDM and Liquid Rubber

If your RV has a damaged roof with leaks, then you could be suffering a great deal of stress and concern. To save yourself from this distress, you would want to use a reliable and long lasting product. EPDM solves the immediate and long-term problems of roofing. Its recurring membrane resistance to fatigue, its intense resistance to ozone as well as weathering and scratches, its flexibility during low temperatures and its durability against thermal shocks are its unique features.

For more than 30 years, EPDM rubber in sheet form has been in use. The Liquid Rubber is a new form of the EPDM rubber with the only difference that it is in liquid form which turns to regular solid EPDM rubber roofing after drying. Liquid rubber provides a flawless, single coat; roof coating that can be applied up to 6 times thicker than your standard elastomeric.

It is not a coating but chemically is part of the rubber it is applied to. In short, it combines all the benefits of EPDM rubber roofing with the flexibility of using a liquid. So use it over your RV roof without any fear and you will surely appreciate the results.

Have a happy camping with liquid rubber!!!!

Roof Repair of Roof Leaks

Finding a leak and making repairs to a pitched roof is challenging enough; attempting the same process on a flat roof is nearly impossible. This is primarily because water damage on this type of roof will never show up anywhere near where the leak originally occurred. The difference lies in predicting how the water will run. On a pitched roof, water will run where? Down. On a flat roof water runs – anywhere it has a mind to, which is why it will probably take the keen eye and experience of a professional roofing contractor to locate your leak and make the necessary flat roof repair.

The first step in is to get up there when the surface is completely dry. This climbing on top of a building is enough to make many folks run for the nearest phone to call their roofing specialist! Once you are on the roof, you can inspect for cracks or holes in the seams of the roof or flashing. Exposed nail heads are another place where water can get in and cause damage. 

You can also check for a ring of dirt or discoloration to the rocks or gravel that may signify a low spot in the roof where water tends to puddle. Check these spots for signs of cracks or holes as well. Testing for leaks on a flat roof can be done – if you have the patience and a few hours to do so. It will require bringing a garden hose up to the roof and running it slowly at the drain points to see if a leak comes out of hiding. 

Keep in mind that it can take many minutes before a leak on the outside will present itself inside. This process will need to be repeated over the entire roof, taking the better part of a day in some cases to discover the culprit. Once you find the point of the leak, you can begin the process of flat roof repair.

This is another point where many homeowners will opt to hire the services of a professional, since flat roof repair requires equipment that the average homeowner does not own and is rather expensive to rent or purchase. Many don't like the idea of spending hours doing handyman work a number of feet off the ground. To keep yourself safe on top of the roof, wear shoes with thick, non-skid soles and pay special attention to power lines located around your house. Do not use a ladder that is in need of repair and always climb one rung at a time. By following these steps, you can do much to prevent a potential accident. More Information

EPDM Rubber For Roof Repair

EPDM Rubber has had a long history of superior performance in hoses, molded products, tires and roofing membranes. For example, the radiator hoses in our cars and the gaskets on our freezer doors are made of EPDM rubber and show the broad temperature range the product can handle. EPDM Roofing Membranes also have more than 30 years of successful history. EPDM is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional materials. 

There are not the strong odors and fumes either. The product is very stable and the resulting characteristics of Liquid EPDM such as flexibility, weatherability and chemical resistance are determined by it. Liquid EPDM therefore, can be described as a new form of an old and well-established rubber polymer. Now you can take advantage of the same benefits to weather-tight your leaks. Liquid EPDM forms a 100% seamless layer. 

No other product can match the durability of EPDM Liquid Roof. EPDM is essentially immune to the effects of ultraviolet and ozone and is one of the best water barriers known. EPDM also has the broadest temperature tolerance, and is not water-soluble even in the uncured state. Even if you happen to get a unexpected rain shower just after you applied Liquid EPDM there's no need to worry; Liquid EPDM will not wash off.

Elastomeric coatings turning roofs and walls into efficient, protective planet- friendly machines for change.

Right now, the roof of the building you’re in is probably a very dark color, if not altogether black. Changing that color to white could radically improve operating costs, reduce utility bills, benefit the surrounding environment, and help everyone in the immediate neighborhood feel a little cooler during warm-weather months. Properly installed coatings of an environmentally advanced white elastomeric will enable the roof to last far longer, too.

The benefits of elastomeric roof coatings are not limited to roofs. Cementitious wall coatings formulated with this tough 100 percent acrylic elastomeric technology remain flexible but retain their tensile strength to protect over a wide range of temperatures. Their flexibility and softness also provide excellent resistance to dirt pickup and prevent wind-driven rain and moisture from seeping into cracks and causing structural damage, even in humid, hurricane-prone regions. Elastomeric wall coatings keep homes in one piece – safe and dry.
“White Knights” to the Rescue

Reducing heat build-up on commercial and residential roofing can dramatically affect building operating costs. Findings reported by the Roofing Manufacturers Association conclude that heat build-up can shorten the useful life of rubber, synthetic polymer, and especially asphalt roofing systems. Cool roof technology utilizing specialized white coatings that reflect the sun’s light before it can be turned into heat significantly reduce temperature. For example, a 95° F day raises black roof top temperature to 170° F, while a white roof would not exceed 120° F — a temperature drop of almost 30%.

Liquid Roof; a true EPDM rubber

Liquid Roof is a true EPDM rubber and is the only one sold in liquid form. Liquid roof makes installations easy. Liquid Roof could be described as a liquid version of the single ply EPDM membrane which has established and outstanding performance record of over 30 years.

The EPDM chemistry has two unique features not possessed by any other rubber. It is unaffected by ultra-violet and ozone, and can tolerate continuous exposure at temperatures over 300 degrees F. The latter feature of liquid roof is also what gives EPDM rubbers the best aging properties (retain flexibility longer) of all elastomers.

EPDM & Single ply

EPDM coatings are made up of elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility and due to which best suits for roof leaks repair and roof leaks coatings. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i.e., ketones, esters, and alcohols). The EPDM single-ply rubber roofing coatings have been an appealing choice for roof leaks repair for residential roofing and commercial roofing industry for over 40 years.
  • The number one roofing choice of architects, roof consultants and contractors for both new construction and replacement roofing projects according to Building Design and Construction magazine and the National Roofing Contractors Association (NRCA) 2002-2003 market surveys.
  • Over 1 billion square feet of new roof coverings in the United States annually.
  • More than 500,000 warranted roof installations on 20 billion-plus square feet.
With wide widths and fewer seams, EPDM coatings improve contractor efficiency during installation. EPDM coatings offer a quick, clean, inexpensive solution able to be installed in a wide range of temperatures. EPDM coatings provide excellent UV and weather resistance as well as sheet flexibility and high elongation. Systems can be installed fully adhered, mechanically fastened or ballasted. A complete line of accessories, sealants and adhesives is also available.

RV roof repair can be a complicated job. However when you are talking about RV roof repair you will usually be dealing with dry rot. Many months of wet weather and/or storing your RV in a poorly ventilated garage can necessitate a bit of running roof repair, and the good news is that unless the damage is widespread or severe, you should be able to do this kind of RV roof repair yourself. It’s especially useful if you have a few tools and a friend who can help you with the lifting which is almost inevitable in RV roof repair.

Things to Consider

When you have to make an RV roof repair you first of all have to think about how big an area is damaged. If you can see water damage inside your RV roof repairs are necessary right now, but ideally you will check the outside of the vehicle to avoid that urgency.

How to do DIY RV Roof Repair

First you need to take off all the fixtures and edge moldings from the roof like air conditioning and plumbing vents and a heat gun may be of help with this as you my need to make the roof coating softer for easier removal of these fixtures. Then you should be able to get at the staples holding on the RV roof and remove those. Just be careful if you ant to re-use the metal from the RV roof; you should be able to roll this off. Once the roof is off you will be able to see the RV roof insulation; get rid of it if it’s at all wet.

This is where DIY RV roof repairs get a little more complicated, because now you’ll see where all the wires go. You’ll of course nee to replace all the wires in the right places, but they are color coded. If you don’t have a wiring diagram, make sure you make one now before you uncouple any wires. Better still – get your digital camera out and take a photo. Only then should you remove any lights or electrical fittings.

Ready to Repair

Now you’ve stripped out your RV roof repairs are made easier. If the damaged area is small you should be able to cut out the damaged piece. The roof should be screwed down so easily removed in panels. Of course, you should make sure any panels you replace are again well secured to the RV framework. Cover any joints with battens that slide in, so the roof is again weather-proof and strong. Remember to cut the holes needed for any roof vents before you do this though!

Then your RV roof repairs are almost done. You need to re-install the wiring and insulation and make sure the roof is completely secured to the side walls but you’ll then be home – and dry – with your RV roof repair.

Liquid EPDM used for Pond Leak Repair

Liquid Rubber Fix pond leaks. Waterproofing Fish Pond, Leaks Repair, pond liner, Fountains, & Reflecting Pools with Liquid EPDM Rubber Concrete which has not been modified with special additives must be protected by impervious coatings when used for containing water. Unprotected concrete will absorb water which can then leach out soluble constituents and cause spalling when frozen. The combination of outdoor exposure plus water immersion creates a demanding environment for a coating. It must have high resistance to water penetration, be flexible enough to withstand extremes in temperature, and not be affected by ultra violet radiation from the sun. Liquid EPDM rubber coatings possess all this characteristics and are also non toxic to fish.
Preparation: Drain water and clean surface dirt while concrete is still wet. High pressure water spray and/or scouring surface with a wire brush may be necessary in fish ponds. If algae is present treat with an algaecide or 25% solution of bleach, let stand for one hour and rise well. Allow one week (rain free) for concrete to dry out.

If you are using this in Koi tanks in immersion conditions, make sure you have 2 coats of Liquid EPDM and that you have a full cure. To do so, let cure in air (without water) for about 1 week in 70 deg F or more ). Soak and rinse out the tank several times with water before making this ready for the Koi. The soaking and rinsing is to ensure you get out any residue solvents after the curing process. You will of course need to prepare the water for the Koy in whatever normal way you prepare Koi tanks/ponds.
Whether your pond is concrete, plastic or rubber lined. EPDM Liquid Roof can fix your leaks troubles. Plastic pond liners have a tendency to crack or to tear. There are products such at tapes and caulks that will eventually wear EPDM Liquid Roof, on the will not. For concrete ponds the easiest solution for leaks are to cover them with a rubber liner but they are tricky to install. Liquid Roof Coatings provides an easy one-time solution to your pond leak regardless of if they are made of rubber, concrete or plastic. And yes, it is safe for fish

Identiying a Pond Leak

The primary function of any pond is to hold water. v Lowering the pond level an inch or two below the stable water level will allow some additional space for inspection. Careful inspection is in order for all ponds. Concrete ponds in freezing climates may have been subject to freeze damage or settling if not on a firm foundation.

The key issue for many ponds is finding the exact leaking area. Children playing in the pond, or well-meaning landscaping near the pond may result in leakage as well. If the details of construction are known, the inspection can focus on finding the leak. Isolating the systems is the key to finding the leak point. If the leak appears when the pump is running, then turn off the pump to see if the containment leaks at all. Even very small cracks or holes can leak substantial amounts of water. If the basic containment is intact, the next step is to isolate any other system components to check for leaks. Edge leaks will generally leave evidence as wet spots along the edge. Dry days are the best for checking pond integrity.

By building a pond with a variety of "inspection points" around the edges, it can be very simple to check pond edges for adequate liner height. - Fold some liner under the edges to have some additional liner available if settling occurs or the owner desires some small modifications. Also check for liner folds that may allow for channeling of the water. Any waterfall or stream should have a liner that overlaps the basic water containment.

Make Roof Waterproof

Stop Making The Same Repairs Using Other Products. One Coat Application With Liquid Rubber. No Primer or Top Coat Needed!
Roof Repair and Leak Repair often made after the damage has been done; however, if you keep up on routine roofs maintenance you can avoid Roof Leaks and unnecessary damage altogether 65% of roofs replacements are performed because of roof leaks.

What liner should I use to line my pond? Would a preformed pond liner be better?


Liners are the most cost effective method of making a waterproof pool in your garden, but what is there really to choose between all the makes and materials? Peter May tells you how you can make it neat or natural and also introduces the new Greenseal liner from Gordon Low.

Don’t you hate all those fancy scientific names and acronyms; those strings of letters that only mean anything to ‘them that’s in the know’. Somehow you feel excluded from all the information. But then again all you are Putting in preformed or rigid ponds can be pretty easy. Getting the level right can be the difficult bit.Putting in preformed or rigid ponds can be pretty easy. Getting the level right can be the difficult bit. after is to make a hole in the ground waterproof.

You have already vaguely contemplated going ‘au naturelle’ by puddling it in clay, but then there is all that mess. And then you thought of manufacturing the pool itself in concrete, but a few sums quickly made you realize not only the muck and disruption involved but also the expense. So then you continue your investigations down the aquatic centre and find a huge range of products that all have different names but all look pretty much the same: black, some are shiny, some are not. Admittedly some are rigid and already pool shaped. They will tell you these are made from are generally HDPE (High Density Polyethylene) or ABS (Acrylonitrile Butadiene Styrene) and those are also fiberglass – mostly bigger heavier pools.

Others liners look like sheets of plastic, whilst some look like rubber. And its here you discover all these exotic names like Pondalene, Aqualast, Maxipool, Alfafol and now everyone is talking about Greenseal - now what’s that?

Despite the variety of brand names most of the liners available are one of several quite distinctly different materials that will all do the same job, and as individual materials they only come from 2 and 3 factories around the world. So it is highly likely that products, or at least the raw materials, with similar specifications will have come from those same factories in America, Belgium or Sweden.

The flexible sheets of material are either PVC (Polyvinyl Chloride) or Polyethylene – those are the shiny ones – and matt coloured ones are EPDM rubber (Ethylene Propylene Diene Monomar) or Butyl rubber. Well as your eyes are glazing over and you feel no wiser, you still aren’t finding the choice any easier. Once upon a time that choice was much easier.
