Here's what you might see when you go up on your roof

Uplifting or splitting of the EPDM roofing membrane (the material that covers the roof) or decking on flat roofs. Punctures in the roof caused by debris hitting it.
Cracking or other age-related deterioration. This is typically most apparent on southern exposures, and especially on wood or composition shingles.

Damaged roof-mounted vents or air-conditioning equipment.
Stripped ridge tiles, or missing or broken tiles on concrete or clay roofs.

This can be caused by:

• Hail or from toxic substances in seedpods.
• Stripped or torn shingles on fiberglass, or cedar roofs
• Algae growth from poor drainage.
• Previous roof repairs.
• Rotted or rusted decking.
• Worn or rusted flashing.
• Wrinkled roofing membrane.
• Holes from missing shingles or other roofing materials.

Roof Coating and its Benefits

Roof coatings are made up of a specialized material that is used as the additional protective layer on the finished roof. As roofs nowadays are made up of several materials including aluminum and other metals that may be subjected to corrosion because of repeated exposure to sunlight and rain and other adverse weather conditions. So the roof coatings acts as the layer of defense between the roof and the weather outside. It varies in thickness. It can be thinner than a paint coat and can be thicker than paint coat as well. So it depends upon the condition of the weather that they may have to deal with that determine its thickness and other factors, such as the quality of the material they are made. They vary in quality and prices. If the coating is applied effectively and correctly, it appears seamless, i-e it does not appear as a separate coating on the roof.

It is said that the most critical and difficult weather element to control is water. The last line of defense that is used for waterproofing of the roofs is roof flashing. Roof flashing is simply a metal sheet usually made up of aluminum that is placed between the walls and roofs in order to restrict the water to enter into the inside of house walls and roofs and cause damage. One of the major benefits of Liquid EPDM is that this layer helps the flashing material to bind with the asphalt to provide more concrete waterproofing.

So one of the most practical aspects roof coating is the waterproofing of the roof. So it not only makes a roof waterproof but it also reduces the exposure rate of the roof to the humidity and rain that may enhance the rate of metal or roofing material corrosion. Another such material that can be used for the waterproofing is liquid rubber coating. It can be easily applied to any roofing material including metals, fiberglass or concrete. It is also long lasting and very durable. The time after which you may have to change a rubber coatings, is far greater than the ordinary coating.

Alongside with the waterproofing, the coating also helps protect the roof from the intense exposure to sunlight that may cause damage to the roof. It absorbs most of the ultraviolet rays and slows down the damage rate of the roof. However coating also has a life period after which it gets damaged and may not remain as effective. Still it is a good option to coat your roof as to change a coating is much less costly and difficult as compared to roof changing.

Moreover coating possesses an elastic nature. As with the changing weather, there may be a change in the size and shape of the roof as it expands in summer and retracts in winter. The coating has the ability to expand and retract with the roof. In this way it remains intact and firmly attached to the roof without the danger of getting ruptured broken.

The procedure of applying roof coating is same as the procedure of applying paint. Apply the coating in successive layers. Allow the layer beneath to dry completely before applying the new layer. You can apply as many layers as you want until you achieve the desired thickness.

According to an estimate, the application of roof coating increases the life of your roof by 20 to 25 years.

Rv Roof Will Guarantee The Longest Possible Life

EPDM roofs are actually ideal, and very easy to protect. Use of treatments that protect roofs is really not required, as the EPDM is already self protecting. In fact, all you need to do to make it last as long as possible is to clean it regularly. It’s recommended that you clean an EPDM roof four or five times each year.

If your rubber trailer roof is more than a few years old, you may well notice a chalky build up on the surface of it. Don’t worry about this; it’s just normal deterioration due to aging that is unavoidable. If you clean your roof often, you will minimize this chalky build up anyway, and it will visibly reduce the white streaks that can be seen on the sides and roof of your RV.

Asphalt based aluminum coatings should be removed as much as possible by wire brush or abrasive disc. Roof cements should be removed and replaced with butyl caulk where necessary. Repair torn rubber with adhesive Butyl Tape. EPDM rubber patch may be applied over torn area if desired. Remove chalk from white rubber membrane by brushing with a detergent solution followed by a water rinse or working surface with a stiff brush. Smooth metal or plastic surfaces should be roughed up to improve adhesion of Liquid Roof®. A deglossing solvent may work on some plastics.

EPDM Give Outstanding Surface Wetting Properties

Roofs are possibly the most important part of a home and often the most ignored one. In addition, the most important job that it plays is of providing protection to the building and its residents. But at the same time it is the most neglected area of the house because as heard often “out of sight-out of mind”, the roof is also generally out of sight. One would not want to go over the roof and examine it for no reason. That’s why, until and unless it starts leaking, no one pays any attention to the roof or its maintenance.

EPDM rubber is a very flexible and long-lasting material that has a huge range of different purposes and applications. EPDM stands for Ethylene Propylene Diene M, in which the M refers to a class of rubbers that contain a saturated chain of the polymethylene type. What that means in simple terms is that EPDM rubber has fantastic heat, ozone, and weather resistance. It is also a great electrical insulator.

EPDM rubber sheets are often used as a liner for back yard water ponds and other man-made water features. The rubber does not leach chemicals, and so would not harm any fish living in these ponds. EPDM roofing material is one of the most common applications of this rubber product, although it can be used in garden hoses, washers, belts, electrical insulation, seals and speaker cone surrounds.

EPDM rubber is also often the main substance used in the weather seals of vehicles, such as door seals, window seals, and hood seals. This is due to the great weatherproof properties of this type of rubber.

EPDM Coatings a solution for your roof repair

Roof is the greatest source of protection from any type of whether condition for the world. But they have to spend more for its repairing and remodeling almost every year especially after rainy and summer season. Roof Leaks are mainly the cause of improper installation and ineffective flashing of roofs at the time of its construction. Roof Leak may occur about any place of the roof buy they found more near the chimney, step, apron, pipes, and points at which two roofs meets. Roof leaks may also occur when your roof shingles installed improperly. If you ignore it for a long time, then they may become a cause of major damage for of the roof.

It is important to ensure that your roof is equipped with building materials that are appropriate to the weather conditions of the area that you live in. Choosing cheap, low-quality materials that do not handle well in certain weather conditions can prove to be a very expensive mistake. This type of mistake especially at the time of construction leads to bear heavy cost of repairing near about each year or in every season.

You can minimize the problem by selecting the material that is more suitable and having great resistance for all type of weather condition like EPDM and Liquid Rubber products are designed especially for it. Elastomeric roof coatings and liquid rubber are also designed for roof leak due to draining water in rain; provide great resistance for water in rainy season. Similarly epdm is the best product for summer sun that can easily control the temperature by providing complete protection to the roof from sunlight.

Technical Aspects of EPDM (Liquid Roof and Liquid Rubber)

Elastomeric coatings are roofing applied in a viscous state. It has elastic properties, and can stretch in the summer time heat and then return to their original shape without damage. Elastomeric coatings usually contain polymeric materials, such as acrylic, and a white pigment, such as titanium dioxide, to make them opaque and reflective. An elastomeric coating is applied thicker than paint. An elastomeric coating can be used on virtually any substrate including asphalt built-up roofing, concrete roofing, metal roofing, modified bitumen roofing, polyurethane foam roofing and single ply roofing.

Liquid Roof and Liquid Rubber need temperatures above 55 degrees to cure. The temps can go below 55 but the product will not begin curing again until the temp's go above 55 degrees. Chemical Resistance-Cured EPDM rubber is resistant to acids, alkalis and polar solvents Cure system-Two-component Peroxide initiated Heat Resistance 302 degrees F (150 degrees C)

Physical Properties:

The physical properties of Liquid EPDM Rubber for roofing are typical of its EPDM chemistry. The outstanding characteristics include:
1. Extreme high resistance to penetration of water, Ultra Violet and Ozone stable, excellent long term aging properties.
2. Very broad temperature tolerance range (from 300 degrees F to minus 62 degrees F). Acid and alkali resistant Withstands ponding water even when not cured

Technical Properties of EPDM

1. Specific Gravity 0.87
2. Color Available white or black

Life Expectancy of Roofs

How long should your roof last? The American Society of Home Inspectors provides the following estimates for the life expectancy of different roofing materials:

• Asphalt shingles: 15-30 years
• Wood shakes-shingles: 10-40 years
• Clay-cement tiles: 20+ years
• Slate: 30-100 years
• Metal roofs: 15-40+ years.

Rain isn't an ally either. Water will naturally take the path of least resistance. For this reason, minor roof leaks can result in extensive damage in various locations throughout a home. Aside from the obvious water-stained sagging ceiling, prolonged leakage will likely result in rot to framing members in the roof, ceiling, walls and floor.

High winds can lift the edges of shingles and force wind-driven rain and debris beneath them. Extremely high winds can tear random shingles from the roof, leaving the roof spotty or even bare in some locations. Properly anchored shingles will minimize this damage.

Snow, ice and hail also do their share to shorten the roof's life. Melting snow often will freeze over the roof's overhang where the surface is cooler creating an "ice dam" which blocks drainage to the gutter, and results in water backing up under the roofing material.

Gutters and downspouts also can freeze, preventing proper drainage. Eave-heating devices can prevent ice buildup. Check with your local hardware store or home center for the one that will work best for you.

Mildew, moss and lichen can accumulate on roofing materials if they remain damp as a result of poor drainage or little sunlight. Once it grows, moss holds moisture to the roof surface causing rot or poor watershed.

One of the best ways to rid the roof of moss and fungus is with a good power washing. (This may be best left to a roofing contractor or roof care professional.) Another way is to apply a solution of one quart of liquid chlorine bleach in a gallon of hot water to the affected areas, using a stiff nylon brush.

Prevent minor problems from becoming major repairs by inspecting your roof in the late fall and early spring. Using binoculars will give you a good view of the roof while keeping traffic on the roof to a minimum. Look for loose shingles or shakes, or, if you have a tile or slate roof, cracked or missing tile. On shingle roofs, look for curling, fraying and tears at the edges.

Here's what you might see when you go up on your roof:

• Uplifting or splitting of the roofing membrane (the material that covers the roof) or decking on flat roofs.
• Punctures in the roof caused by debris hitting it.
• Cracking or other age-related deterioration. This is typically most apparent on southern exposures, and especially on wood or composition shingles.
• Damaged roof-mounted vents or air-conditioning equipment.
• Stripped ridge tiles, or missing or broken tiles on concrete or clay roofs.
• Pitting or pock marking on asphalt shingles or membranes. This can be caused by hail or from toxic substances in seedpods.
• Stripped or torn shingles on asphalt, fiberglass, or cedar roofs.
• Algae growth from poor drainage.
• Previous roof repairs.
• Rotted or rusted decking.
• Worn or rusted flashing.
• Wrinkled roofing membrane.
• Holes from missing shingles or other roofing materials.

Roof Colour Selection

The roof is the ceiling of the house. It really needs to be considered when you’re making color decisions. If you’re due for a new roof, congratulations! You now have a chance to select your roof color from the myriad choices that are available. Here are a few guidelines and considerations:

Suggestion 1; Involves selecting colors within the same family, such as warm tones (browns, beige’s, creams, golds and reds) used together with warm accents, trim etc.

Suggestion 2; Consists of contrasting light and dark colors out of different color families for an eye-catching effect.

Suggestion 3; Contrasting cool (blues, grays, black, white) and warm colors is harder to achieve, but if one of the contrasting colors is a neutral, it will be easier to accomplish. For instance, try using a warm color like cream or ivory with a cool neutral such as a gray or black ridge cap and drip edge.

Once you have chosen the method to create the look or effect you desire, you may want to take the following steps to help make your final color selection:

Gather; samples that represent the outside permanent colors of your home (brick, siding, etc.) You can use paper or fabric or whatever other sample you can find that is very close to the home exterior.

Consider your surroundings; Consider the environment and your neighborhood. Coordinating with your neighbors home should not be a prime consideration, but duplicating your neighbors home would not be ideal either.

Select Similar Colors; Select colors in the same family as the existing permanent elements (i.e. brick or stone) to produce a simple scheme which will make a small home appear larger. For example, a light brown shade of shingle on a tan colored brick home.

Select High Contrast; Select high-contrast colors to produce a bold, striking effect. These highlight architectural detail and design. Low-contrast colors hide details which may be desirable in some cases.

Using Color to Balance; Use color to balance the proportion and design of a home. Light colors make homes appear larger, dark colors make homes look smaller. Dark colors outline architectural details against light backgrounds while light colors create the opposite effect.

Traditional Shingle Roofs

• Gray or blue house. Stay with a traditional roof color like dark gray or black. That way your roof will blend with your house and make the whole structure seem bigger.
• Cream, tan, or light brown house. Consider the many brown roof options, some of them with a mixture of browns that really make the house look updated and terrific. A brown roof will blend with the cream or tan and make the house look bigger. Black and gray roofs just look ordinary.
• White house. Stick with a dark gray or black roof. It’s traditional, but it works.
• Red, green, or yellow house. You can go either way, a brown or a gray/black roof. I prefer a brown roof for red and green house colors and a black roof for a yellow house.

Nontraditional Roofs

What about metal roofs? They’re all over Colorado, Upstate New York, and other areas of the world where snow on the roof is a major factor in the winter. Metal roofs come in a rainbow of colors, from red to green to brown to purple. If you have a metal roof, you are making a design statement (whether you meant to or not, of course) and you can treat it as an accent color, kind of like picking a front-door color.

What about terracotta roofs? These are traditionally seen on Mediterranean style homes and are a definite design feature. Keep the house color neutral to highlight the beautiful roof and the other architectural elements that are undoubtedly present.

Other Nontraditional roof materials. Just like a thatched roof on an English cottage, a nontraditional roof is a design feature of the home. Hopefully, you want it that way. Choose a house color that makes the roof look like you planned it as a feature. Regardless of what kind of roof you have, make sure you consider it when you’re making house color decisions.

Roofing Issues

The life of any roofing system is finite. Most low-slope roofing materials begin to exhibit water infiltration within 20 years after installation. Distress conditions and leaks on low-slope roofs are more likely to emerge at certain predictable areas, such as at punctures or seams in single-ply membranes.

Leaks also often occur where pipes or vents penetrate the roof membrane, as well as at roof perimeters where roofing systems transition to other materials. By identifying areas that are prone to developing problems, maintenance and engineering managers can take steps that will prevent roof problems cost effectively.

The key to a trouble-free roof is obviously doing your best to repair problems as soon as soon as they arise - but even more importantly taking steps to identify potential weaknesses before they result in disaster. Be sure to consult a qualified roofing company or inspector to put your mind at ease, and never be afraid to ask for a second opinion. Regular maintenance, inspection and weather-resistant additions should keep you and yours happy, warm and dry for many years to come.

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.

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.

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%.

EPDM Liquid Rubber

Liquid Rubber is a unique product that has a successful track record in the world market for over 20 years. Liquid rubber has a resistance for the extremes of temperature.

Liquid Rubber coating has 700% elasticity. Liquid Rubber forms a waterproof and seamless coating when dry after the application. Liquid Rubber retains its specifications in the temperature range of-20C to + 80C due to its resistance to UV and sunlight, can be used with full confidence even on places such as terraces and roofs that are under exposure to intense sunlight.
Liquid roof features very high flexibility and crack-bridging ability. Further Detail can be Found at " LIQUID RUBBER "
