Liquid EPDM Coatings are aftermarket roof sealants

Posted on December 3, 2012 by Greg Kaz.

A number of aftermarket roof sealants are available, including urethanes, acrylics and liquid rubber. Liquid EPDM rubber is by far the most durable of the sealants available and has the widest range of applications.

It is more water resistant than other rubbers, including neoprene. It is more resistant to swelling and has a wider range of acceptable temperatures. It can be applied directly to practically any roofing material other than asphalt and can even be used on wood that has been primed.

Liquids have an obvious advantage over sheets. Sheets have seams. Seam sealers eventually deteriorate and water gets through the seams and under the sheeting.

Liquid EPDM can be used on top of neoprene, although some pre-treatment of the surface is required. Just knowing that the liquid rubber is recommended for use on top of the other type of rubber should be an indication that the material is more durable.

Liquid EPDM can also be used on top of polyurethane after a light sanding. It is somewhat surprising that urethanes are still used as aftermarket roof sealants. It is known that the structure is damaged by UV light and that discoloration occurs relatively quickly. Anyone who has made the mistake of using urethane as a roof sealant should consider applying liquid EPDM to truly protect the roof.

The liquids can also be used to seal existing leaks. They are self-adhering and fill up tiny fractures that let water through. It is a good idea to use a thick coat and cover the entire surface instead of attempting to only cover the leaky area.

When covering the entire roof, the liquid rubber reduces heat buildup. Not only does the roof stay cooler, but the interior of the building or the vehicle will also stay cooler. This benefit may reduce heating costs and keep the occupants more comfortable.

Liquid EPDM has become the most popular choice for RV roofs, because of all the above-mentioned advantages. It extends the lifespan of the roof and requires less maintenance. It lasts up to three times longer than any other aftermarket RV camper rubber roof sealant and also reduces noise from rain.

As far as price goes, most sealants are similar in price. Depending on where you buy, EPDM may be a little more expensive, but because primers and additional coats are not usually necessary, and because it lasts so much longer, owners who choose this aftermarket roof sealant save money in the long run.

Information about Liquid Roof and Its Benefits

Here you can learn a bit about liquid roof and its benefits for new and existing construction. Let’s start with the basics.

What Is It?

Liquid roof is a liquefied version of a synthetic rubber typically referred to as EPDM. The letters EPDM stand for ethylene, propylene, diene monomer and M class respectfully.

Before the liquefied version came on to the market, rolls of the rubber were used for waterproofing roofs. The liquids are easier to apply. They fill up cracks and crevices. They can go where the sheets could not go.

Why Choose the Liquids?

Ease of application is one reason. The foil is more difficult to apply correctly. You could easily end up with bumps, overlaps and uneven spots that contribute to water pooling. Water can seep under the rubber sheets and cause the roofs to leak. So, while the rolls were the best choice for waterproofing at one time, there are better choices today.

The liquids have more uses. They can be used on RV roofs and other vehicles. They can be applied to a wide range of roofing materials including metal, fiberglass and wood. Through the use of an undercoating, the liquids can be applied to built-up and asphalt-based coatings. Other reasons to choose the liquids are listed in some detail below.

Liquid Roof and Its Benefits for New Construction

For new building construction, applying the liquids increases the lifespan of caulks and sealants used to waterproof around flashing, vents, HVAC units and other protrusion points. If the new roofs are made of steel or aluminum, the liquids prevent rust and effectively extend the life of the roofing material.

If you choose white, which is the base color typically provided; the coating reduces heat within the building and also helps to protect the surrounding environment from excessive heat. Black and dark colored roofing materials are partially to blame for the high temperatures seen in southern cities during the summertime. By reducing heat within the building, the coating helps reduce air conditioning costs.

Liquid Roof and Its Benefits for Existing Construction

When applied over the entire area, the coating provides the same benefits for existing roofs as it does for new ones. It can also help to reduce noise from rain falling on metal roofs.

For roof leaks and general waterproofing, the roof coatings are the least expensive and most effective choice. So, there you have the facts about liquid roof and its benefits. It’s a money-saving environmentally friendly alternative.

Roofs Types, its repairs and coating materials

Posted on January 31, 2012 by webmaster

When we get tired of the whole day’s activities our most imperative want becomes to go home and get relax. As the thought of going home comes to our mind a smile comes to our faces unconsciously because of a peaceful place for tranquil. Home is the place which gives soothing and comfortable thought to everyone. It serves as a shelter from all the outside and environmental harms. Roof is the most important element of the home construction and its most intricate thing to repair and re-roof. Before deciding on roof repair or repair decision, all of us must be aware of the expected roof lives.

All roofs are made from different materials and each type of roof has a different lifespan. The best way to determine how long you can expect your roof to last is to check with the manufacturer’s warranty. However, you should also realize that with a preventive roof maintenance plan that utilizes seasonal inspections, you could greatly enhance the lifespan of your roof. When considering roofing materials, always talk with your roofer about the steps that you should take to maintain its condition as well as anything that you should do to ensure that you don’t void the warranty. By taking the time to choose the best roofing materials for your house’s design, structure and geographical location, you will have a better chance of enjoying new roof for many years.

Most commonly, roofs fail because some aspect of the installation was done poorly. Many roofers don’t pay much attention to the details. Problems caused by poor installation often don’t show up for five or ten years. By the time there’s a leak, the home has changed hands or the homeowner has no recollection of who did the roof — let alone any idea where to find them. There are plenty of sloppy roofers out there that never even know about the problems their poor workmanship causes.

Then there are the lucky few homeowners whose roofs fail simply because the materials have surpassed their useful life. Typically these roofs go 20 years or more without a leak and replacement becomes obvious because many of the shingles are starting to curl or tear. Many roofs are covered with asphalt shingles. These shingles should last 20 years or more but often fail after about 15. If your roof is starting to leak and is 15 years old or older, there is a good chance that you’ll need a new roof soon.

All conventional flat roofs are exposed to surface deterioration under the action of sun, wind, driving rain, hail, ice and snow, traffic, building movement, temperature cycling and water ponding. It is because of this process of degradation that a roof must be inspected yearly. When a leak occurs in a flat roof, a more serious type of deterioration occurs. Even if water does not enter the building, it attacks the insulation. Destruction of the roof system can progress rapidly and cause damage for which repair is costly or impossible. This phase of deterioration is neither inevitable nor normal for a properly designed and constructed roof, and usually is merely the result of neglect and lack of maintenance.

It is difficult to comprehend how a roof, which is an expensive element of the building, can in many cases go on unattended for years. It is similar to buying an expensive car and being content to only add gas when necessary. Both car and roof will fare miserably before they reach half of their designed life.

Another aspect of roofing to consider is the material that is used for the underlayment, sheathing and trusses. If you are building a new roof, you should realize that all of these parts to your roof system would come with warranties as well as methods of maintenance and care. You should also have plenty of adequate ventilation included in your roof system to help preserve the life of your roof. Taking the time to discuss all of the options available with your roofer will help you to maximize the most from your roof.

The primary advantages of liquid roof coatings are their economical, proven performance life, and ease of use. Roof coatings are generally very good weather and water sealant. Today’s liquid roof coatings are versatile and applicator friendly. Non-flammable products are also available.

It’s important for you find a good coating for your roof: you want a coating that will protect your roof from the elements and make it last even longer than it traditionally would. You have several main choices for roof coatings. There are pros and cons to each. Roof coatings can be put on your roof at any time during the life of your roof. However, it’s usually best to put the coating on the roof when your roof is replaced or if your notice any leaks in your roof.

The most widely-used roof coatings product is the acrylic elastomeric coatings. This type of elastomeric coatings can extend the lifespan of the roofing system through a dependable protective finish. Elastomeric coatings are also preferred by green building enthusiasts because of its environment-friendly coating formulation.

Roofing Types & Problems

Posted on January 31, 2012 by webmaster

When we start talking about roofing problems, the first thing we need to know about is types of roofs prevailing in the market and the pros and cons of each roof type. Whilst Roofing is constantly exposed to the elements, structural shifting, and stresses as well as chemicals in the atmosphere all take their toll on your roof. Aging occur on all roofs, wear and tear stemming from neglect, abuse, contamination, and accident can result in expensive repairs or premature failure of the roofing system, if not detected. A Regular inspection program will help detect minor problems before they become big ones, avoiding interruptions of work going on inside the building, and most importantly, protecting the owner’s investment and adding many years to the life of a roof.

Roof Types:

Wood: There are two types. Shingles are cut to a specific size and smooth finished. Shakes are irregular and rough-textured. Wood gives a natural look to a home. It also requires more maintenance to protect it from the elements.

Metal: Metal roofs have returned from the olden days to become a popular roofing option. Once limited to low-slope structures, standing seam steel roofs can now be used on steeper roofs as well. Metal is durable, practically maintenance-free, heat reflective and non-flammable. Installed in sheets, a metal roof will actually dissipate a lightning strike rather than conduct it.

Built-up Roofing: Built-up roofs are installed on flat or very low-sloping structures. They consist of alternating layers of felt or fiberglass treated with asphalt. These layers are topped with asphalt (tar) or aggregate. Built-up roofs are more common in commercial buildings.

Tile and Slate: These are two of the oldest roofing materials around. They are long-lasting and durable. Their weight requires a reinforced roof structure that can support them. Both can be quite expensive and neither is easy to install.

Slate Roofing: is a very expensive choice, but it’s very beautiful and distinct. Many Colonial and French homes look very appealing with this style of roof materials. Slate roof materials are heavy, as you can imagine, and will need additional structural support.

Factors that affect roofs

Sun delivers a combination of ultraviolet rays and heat can prematurely age a roof.
Snow or ice that melts and refreezes (called ice damming) pushes up the roofing material and causes leaks. Ice damming can be a temporary problem that ends when the thaw is complete. Excessive amounts can damage the roof and roof structure.
Rain is normally kept at bay by a roof. But when rain or moisture gets underneath roofing, damage can occur.
Wind can remove any roof in the most extreme occurrence. However even minimal amounts can weaken a poorly installed roof by letting dirt and moisture get underneath.
Moisture from condensation underneath a roof not only harms the roof and sheathing, but also can cause problems inside of the house.
Trees provide shade to help cool a house. They also provide leaves and limbs that can fall or scrub against the roof.
Algae and moss get a foothold on moist surfaces. Excessive growth can retain moisture and cause eventual weakening of the roofing material.

Other Causes of Roof Problems:

Improper Installation
Improper Design
Lack of Maintenance
Flashing Failures

Each of these major causes of roof damage can be minimized by regular and careful inspection for early and minor problems. Immediate attention to any flaws or damages with competent repairs can help you avoid major damage to your roof and prevent the need for early and costly roof replacement.

Having a roof that leaks is a very common problem of many homeowners, especially if you live in an area that sees a lot of rain. When your roof leaks there are a lot of problems that can happen such as mold and mildew stains, damaged foundations, and water stains on the ceiling, just to name a few. Because of this it is important for you to have the knowledge of how to find the leaks in your roof.

When you do discover a leak in the roof you should not panic but simply know that it is time to fix the leaky roof. A leak can actually be a good sign as it will force you to check the leak and it is a good idea at this time to look over the entire roof to see if there are any other leaks or problems. Fixing a leak in your roof is not very expensive and it does not take a lot of time.

The Common Roof leaks problem can best be solved by using EPDM. It is compatible with all types of roof problems caused by sunlight, snow, moisture, rain wind and other causes etc. EPDM is the broader term among roofing material used for repairing, it includes liquid rubber. EPDM is compatible with almost all types of roof including flat roof, sloped roofs and other times of roofs mentioned in this article.

Roofing and Factors for its Repair

Posted on January 31, 2012 by webmaster

You would have heard and read many articles on roof repair and its preventions but this article will discuss factors to be considered while going for roof repair and reproofing decisions. Roof repair is one issue just about every homeowner frets about. Water leaking into a home can cause serious damage in a short amount of time. Just one leak from one storm can cause an entire drywall ceiling to fall dropping mushy gypsum board and messy fiber glass insulation onto you and your possessions.

Roof leak repair doesn’t have to be scary. There are tough roofs to work on no doubt. Attempting roof repairing on a steep slate roof repair should be left to the professionals. The same is true for metal roof repair or even tile roof repair. These are tricky materials to work with. But you should be able to successfully do home roof repair if you have a low-slope roof, a cool day and the right attitude.

The most important factor in any roof repair job is which contractor you choose. A good roofing contractor will check the area surrounding the leak in your roof for any sort of water damage. They should be able to let you know whether or not there is rot or water damage present, and whether or not it’s bad enough to need repair immediately. In today’s economy, cost is another important factor for roof repairs. There are many types of roofs here in Miami, and each type is going to have a different price range for repairs depending upon supply cost and availability of experienced contractors.

Roofs may need replacing for several reasons. It may be leaking and be more economical to replace rather than repair it. The roof may not be working correctly or does not look good. Another reason for replacing the roof may be because you are extending your home and want the roof to look fully uniform.

Over the past 45 years, EPDM single-ply roof systems have grown considerably in market share compared with their modified bitumen and built-up competition. As a result, there are many aging EPDM roofs, and consultants will be faced with the task of providing cost-effective, durable solutions to keep the roofs in proper working order without tearing them off entirely.

Several factors come into play and impact consultants’ decisions regarding the end of a roof system’s useful life. Thermal bridging, proper drainage, R-value, surface color, wind uplift, and hail resistance are all important factors to consider. When every thing is taken into account, consultants are faced with two primary choices when addressing an aged EPDM roof besides a complete tear off and replacement: restoration and re-cover.

EPDM roof restoration usually encompasses reworking the flashings, seams, and terminations, while leaving the field membrane in place. EPDM is well known for its long-term weatherability, so in most cases the field membrane has life remaining. This option is used primarily when the owner wants to extend the life of the existing roof or warranty cover age for an additional five to ten years.
EPDM roof re-covers provide the ability to address more issues than typical restorations. Proper drainage, thermal bridging, enhanced R-value, altered surface color, as well as enhanced wind uplift and hail resistance, are all issues that are better addressed with a roof recover.

The cost of roof coatings is typically about 50% of that of re-roofing and the benefits are very tangible;

substantial reduced cost over re-roof
reduction in cooling costs with 80% reflectivity
years of longevity given to the existing roof
minimal disruption to the work environment during its application
minimal waste going to landfill
annual reduction in cooling costs as high as 22%
no toxic odours or vapours
ease of future repairs
no increase in roof weight load

reduced long term maintenance and roof repair costs
