Flat Roofing Materials Compared

There are three basic types of flat roofing materials, although there are variations within the three categories that allow building owners to have more choices. Whether your building is new and this will be its first roof or you are replacing older roofing material, here are the three main categories you will be able to consider. There are inherent advantages and disadvantages of each type.

Built-Up:

Built-up bituminous roofs have been the standard for many years. They are still relatively popular primarily because they are inexpensive.

Built-up bituminous roofing is created using layers of hot tar, gravel, a smooth river stone ballast and tar paper or fiberglass membranes. Other than the lower cost, the advantages include fire resistance and some people think the appearance is more attractive.

There are several disadvantages. The material is very heavy. The underlying joints of the roof may need to be strengthened in order to install this type.

The installation itself is messy and smelly. It is not a do-it-yourself job for the building owner.
Once installed, it is hard to find leaks in the material and repairing leaks can be difficult. As time goes by, the gravel can break loose and clog the gutters. This choice is not recommended for buildings that are currently occupied.

Modified Bitumen:

Modified bitumen sheeting has a mineral-based surface to convey the fire resistant benefits of built-up bituminous with less weight. The sheeting consists of a single layer that is rolled onto the roof. The sheeting may be attached using a “torch-down” system, although newer modified bitumen rolls have a peel-off backing that sticks to the existing surface. The peel-and-stick installation can be a DIY project for the building owner.

One advantage of modified bitumen has to do with the light colored minerals that are embedded in the sheets. The minerals reflect heat, which can convey energy savings in areas where summer air conditioning costs are high. This is also an affordable alternative.

The main disadvantage of the torch-down system is the risk of fire. The process is not recommended for buildings that are currently occupied. The sheets are not the most resistant to scuffs and tears. Modified bitumen is considered less durable than the next type.

EPDM:

EPDM is a type of synthetic rubber. It resembles an inner tube but has been engineered to resist damage from sunlight. EPDM sheets are available and can be anchored with fasteners, glued on or ballasted with stones. Liquid EPDM rubber is also available for waterproofing or coating existing roofs to extend the lifespan of the roof.

The advantages include easy installation and high durability. Rubber is inherently accompanied by a reduced risk of leaking. If leaks do occur, they are easy to locate and repair. There may also be a sound-reduction advantage.

The only disadvantage may be heat absorption depending on the color selected. Lighter colors are recommended for warm climates but may cost more.

Some building owners feel that the cost is a disadvantage. EPDM does cost more than other roofing materials. But because it is more durable and typically lasts longer, EPDM may cost less in the long run.

The Causes of Ice Dams and How to Prevent Them

Ice dams occur due to uneven temperatures on a sloped roof. The greater the slope of the roof, the more damage an ice dam can do. The process is usually set into action by snow, although an ice storm could also be the trigger.

What happens is that snow or ice on the higher portions of the roof melts. The melt or water flows down the slope until it reaches a point on the roof where the temperature is below freezing. Often, the point that is below freezing is an overhang where there is little or no warming from radiation, convection or conduction of heat.

When the water reaches the lower temperature, it freezes. Water from above continues to flow down the slope and remains liquid until it reaches the ice. Over time, the result is an ice dam. It is a dam in that it traps water behind it. The water can only freeze if it reaches the colder portion of the roof.

Icicles typically form below the dam as some melting occurs during the day. Seeing icicles along the edge of a roof can be a sign that an ice dam has formed.

The damage that occurs to the building is mainly from the water, although the weight of the ice can also cause damage if the overhang on which it rests is not strong enough to support the weight. The water behind the dam searches for an outlet. It starts to work its way through the roofing material and into the insulation.

Once inside the building, the water spreads through the insulation and down the interior walls. It can also spread across the ceiling causing stains and damage to dry wall or other materials.

Ice dams can be prevented in the planning stages of a newly constructed roof. Additional insulation can be used to make sure that the ceiling is airtight. Warm air travels through the ceiling and into the attic space. The warm air rises, causing the higher portions of the roof to be warmer than the lower portions.

Reducing heat loss prevents snow melt. The roof must be strong enough to support the extra weight of the snow. In areas where a large amount of snow falls on a regular basis, there are usually requirements concerning the load that a roof can bear.

Snow rakes can also be used to remove snow and prevent ice dams. Caution is required when using the snow rakes to avoid personal injury and prevent damage to the roofing materials.

There are products like elastomeric coatings, liquid rubber and liquid roof that are one the best products in the market to save your roof from damage.

The Effects of Environment on your Roof

The effects of environment on your roof are responsible for how it changes in appearance as the years go by. Just as your skin ages, so does your roof. One thing that ages both your skin and your roof is the sun.

The sun can cause the temperature on the roof to be 50-75 degrees higher than the temperature of the surrounding air. The heat alone can cause some roofing materials to blister and crack. It’s the main source of roof leaks.

In addition to the heat, the sun is a source of UV radiation. UV radiation has been shown to degrade the asphalt layers that make up your shingles. A protective layer of colored granules is used to reduce this effect. Liquid EPDM Rubber coatings are the best option to coat your roof shingles. Without that kind of roof coating the shingles would degrade very quickly. The use of the granules has added years to the lifespan of modern roofs.

Sudden changes in the roof temperature also speed the shingle aging process and roof starts leaking. Thunderstorms are common occurrences on hot days in many parts of the world. The temperature on the roof rises gradually as it is heated by the sun. When the rain starts to fall on the roof, the temperature can drop as much as 60 degrees almost instantly.

The wooden decking beneath the shingles expands with the heat and then contracts suddenly with the quick cooling. This places a strain on the shingles. As with other effects of environment on your roof, the aging process is relatively slow. But you have these sudden changes in temperature many times during a year. This is one of the reasons that shingles have a limited lifespan.

Moisture from rain and snow also has a negative effect on your shingles unrelated to the temperature change. Moisture causes wooden roof decking to expand. From the perspective of the shingles, the deck is moving. The movement loosens the shingles.

The effects of environment are worsened because of pollution and acid rain. Pollution hits the roof along with raindrops. Smoke from car exhausts, factories and other sources lands on the roof. The pollution causes the color of the shingles to darken, sometimes only in spots that are noticeable from the driveway.

Acid rain degrades the asphalt in shingles. The acid eats away at all parts of your roof gradually.

None of these changes occur suddenly. It may seem sudden if you get up on a ladder to clean the gutters and suddenly notice curling, blisters, cracks or stains. There is only so much you can do to minimize the effects of environment on your roof. Some aging is inevitable.

Summer is the best time to fix your roof leaks problems. You can get rid from such roofing problems by selecting the best roofing products like liquid epdm, liquid rubber and liquid roof coatings for your roof. Liquid Rubber is the only Liquid EPDM product in the world. Liquid roof coatings are also the best option for your RV Roof Repair problems.

A Brief History of Roofing Materials

A complete history of roofing materials would start in the Stone Age. Popular modern material has not been around quite that long but even clay roof tiles have been in use for thousands of years.

Of course the manufacturing processes have changed and improved. People are no longer limited by the location of the material. That was a major factor to consider before present-day shipping methods were introduced.

Clay tiles are popular in some areas and for some architectural designs. The tiles are more expensive than other options but they are long-lasting. Shingles are a far more popular choice.

The history of modern shingles is not nearly as long as that of clay. Wood shingles or shakers were used until insurance companies started refusing to insure homes and businesses with roofs covered by them.

The first composite roof material was used in the 1840s. They are referred to as composites because they are composed of two or more substances, rather than a single material. Modern shingles are composites but the first composite roofs bore little resemblance to the ones we use today. Also there are lots of roofing materials like Liquid EPDM Coatings, liquid roof and liquid rubber coatings are available in the market for fixing roof leaks.

The substances used in the earliest composites were felt or woven fabric, pine tar and sand. Improvements were made by saturating the fabric with asphalt and substances such as sand, crushed limestone or talc. Coal tar came next in the history of roofing materials.

Coal tar is a byproduct of coal manufacturing processes. It was not until the introduction of gas lighting for city sidewalks that enough of the byproduct was generated to find an application in the roof industry.

The coal tar was mixed with fine gravel and rolls of felt were saturated with it. The rolled material was then attached to roofs. Asphalt shingles soon replaced the rolled material.

Henry M. Reynolds made a significant contribution to the history of roofing materials. He came up with the concept of shaping the earlier asphalt-coated roof fabrics into individual shingles in 1903. Reynolds was a roofer and manufacturer. The first shingles he produced were hand cut with a sharp knife.

In 1914, F.C. Overby began adding crushed granules of slate to add weight to the shingles and keep them from blowing off the roof. Roller-die cutting machines were perfected the following year making the mass-production of shingles more practical. Most of the changes that have occurred since that time have been decorative, except for the use of fiber glass to reinforce the felt fabric, which occurred in the 1970s.

That is a very brief history of roofing materials that are very helpful for repairing roof leaks. Liquid EPDM Rubber and Liquid Roof coatings are the best roofing products that will give you cost effective solution for your roofing problems. Although there are other choices, composite shingles are still the most popular for homes.

How to Maintain Your RV EPDM Roof

With proper care and maintenance, your RV EPDM roof can last for 20 years or more. That’s pretty much equivalent to the life of the vehicle itself. One of the benefits of EPDM Rubber roofing materials is that the care and maintenance required is minimal. Regular cleaning is the first step.

Most manufacturers recommend cleaning the roof at least four times per year. The cleaner used should be one that is specifically designed for EPDM roofing and is free of petroleum distillates.

Products containing petroleum distillates, whether they are designed for cleaning or protecting, will cause the rubber to swell and loosen. There are many chemicals that fall under the category. The easiest way to tell for sure that the cleaner you are using does not contain any of the chemicals is to look for one that states on the label “free of petroleum distillates, safe for use on EPDM Coatings materials.”

Cleaning is a relatively simple matter, but you should keep your safety in mind. If you are going to be getting up on the roof, you should be on your hands and knees to reduce your risk of falling.

The first step is to rinse the roof thoroughly with plain water at a relatively high pressure. Any branches or sharp objects should be removed by hand, if possible. While EPDM is tear resistant, sharp objects can cause scratches when they are pushed along the surface. Eventually the scratches can become tears.

Once all debris has been rinsed away, you will need to take a medium bristle brush, a bucket of safe cleanser diluted with water and get up on the roof. You need only scrub in areas where you see stains or dirt.

Keep your hose with you so that you can rinse while you are cleaning. Start in the corner farthest away from your exit point and work backwards to minimize the amount of time you spend on the wet surface.

After the roof is cleaned, you can use an EPDM protectant if you like. The protectant should be specifically designed for EPDM roofing, not for other types of materials. Some EPDM manufacturers also sell special protectants. While using the protectant is not essential, it may extend the life of the roof and reduce your need to restore or repair the roofing material.

Finally, proper care of your EPDM roof includes parking it in an area where the roof is protected as much as possible. Don’t park around fruit trees. The citric acid can deteriorate the material in between cleanings.

Liquid EPDM and its benefits

The EPDM roofing association which started in 2002 has always focused on educating contractors and the roofing community on the characteristics and benefits of EPDM membranes. Their studies have concluded that EPDM’s service live is over 20 years. Arguably the most important benefit of an EPDM system is the membrane’s flexibility. A growing number of contractors are specializing in EPDM installation, due to its low callbacks and insurance premiums. EPDM roofing systems also feature low maintenance, easy repair options and low annualized costs.
With Liquid EPDM there is No cutting, No gluing and No Seaming! EPDM Liquid Rubber® totally eliminates the problems encountered with single ply materials because it produces a seamless membrane which is all of the same chemistry. So what do we gain by using EPDM Liquid Rubber®? It eliminates seam failures and eliminates shrinkage of the single ply rubber. It also prevents further chalking particularly with white EPDM and it extends the life of a roof. Liquid Rubber®, available through Epdmcoatings.com is the only EPDM in Liquid form. This product is a high solids solution of sheet EPDM Rubber. It converts from liquid to solid elastomer via a unique free radical cure mechanism which works at temperatures of 55° F and higher. EPDM Liquid Rubber® can be applied directly on many types of substrates that have solid, stable, non-porous and uniform surfaces such as flat roofs. For most substrates, primers are not necessary. As an example, some types of substrates that can be coated with EPDM Liquid Rubber® without a primer are:
• EPDM Rubber Membrane on flat or sloped Roofs
• Weathered Steel Siding
• Outstanding barrier for salt-water environments
• Weathered Fiberglass
• Weathered standing seam and corrugated metal roofs
• Weathered Vinyl, PVC and Polycarbonate plastic
• Foam insulation for pipe
• Cast Concrete foundations
Liquid Rubber® may be applied at any temperature that permits it being spread onto the surface. It will waterproof immediately upon application. The solvent will evaporate at a rate governed by temperature but will not be affected by relative humidity. Exposure to freezing temperatures before cure has taken place will not damage the film. The time necessary to reach cure should not be a concern as this process will occur automatically. Exposure to sunlight will accelerate the curing process. The final film properties of the cured membrane will be the same regardless of the time required to achieve cure. EPDM Liquid Rubber® will provide long term protection even under extreme exposure conditions. It is resistant to temps of 300 degrees F and minus 62 F. Liquid rubber is water resistant even in an uncured state. An unexpected rain shower shortly after application will not wash it off. The slow cure and non-polar nature of EPDM Liquid Rubber® gives it outstanding surface wetting properties. The product does not fill cracks and crevices but will produce an even film penetrating even the smallest surface irregularities. When EPDM Liquid Rubber® is applied over porous surfaces such as poured concrete, pinholes will appear on the surface as the material slowly displaces the air in the pores. This surface wetting feature enables the product to be applied in a SINGLE COAT and the still results in complete film integrity. EPDM Liquid Rubber® can be applied to hot surfaces encountered during the summer. The solvent in the system will flash off rapidly but the polymer will remain soft long enough to permit overlapping even after 1-2 hours. The cure rate is still controlled even at temps up to 120 degrees. The product can, therefore, be applied on the hottest day.

The controlled cure rate also results in a longer pot life, giving the applicator more than adequate length of time (4-6 hours depending on temperatures) to use the mixed quantity of material. Adhesion will increase over time. Polar surfaces such as metal, concrete and wood result in stronger adhesion than non-polar surfaces such as asphalts. Most weathered surfaces including single ply and thermoplastic membranes will have enough of a surface profile to anchor the EPDM Liquid Rubber®
By itself, the EPDM Liquid Rubber® membrane will exhibit the characteristics of its EPDM chemistry i.e. U.V. ozone stability, excellent ponding water resistance and long-term retention of flexibility. EPDM Liquid Rubber® applied over generally sound singly ply EPDM can extend its life another 20 years. The useful life of metal roofs will also benefit greatly when EPDM Liquid Rubber® is applied. It is recommended that a corrosion inhibitive primer first be applied to areas where severe rusting has occurred. EPDM Liquid Rubber® does not contain any corrosion inhibiting pigments but it is such an effective moisture barrier that it can be applied directly over light rust without a primer.

The Best Roof Coatings for Your RV Roof Maintenance

When it comes to maintaining your vehicle’s roof, the first step is to make an inspection at least once a year. That could mean getting out your ladder. Be careful. Remember that most accidents occur at home.
An annual power washing is usually recommended. If you have been to the beach, take the time to wash the salt and sand off of your vehicle on your way home. Salt and sand are corrosive. The best coatings for your RV roof maintenance help to protect against this kind of corrosion, but cleanliness is still important.

The best coatings for your RV roof maintenance are the ones that last the longest. Most experts agree that the longest lasting sealants are the ones made of EPDM rubber.

EPDM is a material often used in new construction of the vehicles. The manufacturers apply the rubberized membranes to the metal roofs to protect them from the elements, to help prevent rusting and to provide some protection against debris.

It is often debris though that causes the damage. Rapid temperature changes hail and even sudden afternoon showers can cause damage too.
The least expensive coating alternative and the one used most commonly is an acrylic water-based product. While that might seem like an inexpensive alternative, it can be costly in the long run. The temperature extremes and other threats mentioned above can partially or totally destroy an acrylic coating, leaving the metal exposed.

You might not know that the metal is exposed until you see a leak or do annual maintenance. By then, there could be rust and damage to internal insulation and other materials. You should be able to see how costly the whole thing can become.

If you choose the best coatings for your RV roof repair, you could save money in the long run. If you’re smart, you’ll choose to apply the coating when the vehicle is new as a protective measure. You’ll just have to check to make sure that you are buying a brand that is compatible with the materials used in the construction of your vehicle.

Not only does a liquid rubber coating provide benefits that include waterproofing, protection against damage from flying debris and increased lifespan of the vehicle reduced risk of leaking. The coating improves the cosmetic appearance and often helps to keep the interior of the vehicle cooler during hot summer months. There may also be some soundproofing advantages when you choose the best coatings for your liquid roof maintenance.
