Liquid EPDM Coatings are aftermarket roof sealants

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.

THINGS TO REMEMBER WHEN USING LIQUID RUBBER

1) Catalyst must be added prior to use. Scrape sides of container with a Liquid rubber spatula to ensure catalyst distribution.
2) Xylene or Mineral Spirits Solvents may be added to adjust viscosity or for clean-up.
3) Easiest way to spread the rubber on a flat surface is to broadcast material with a rubber squeegee then roll using a short nap roller. Product is self leveling. A flat spatula can be used for small areas.
4) Product has a long pot life after catalyst has been added; 4-6 hrs. depending on temperature.
5) Only temperature affects the rate of cure. Relative humidity has no influence.
6) Product is hydrophobic (sheds water) so substrate to be coated must be dry initially. The uncured rubber can get wet or even have ponding water, with only a cosmetic effect after application, and will still cure.
7) The rubber will penetrate into porous substrates such as wood and poured concrete. A primer/sealer should precede application of liquid rubber.
8) The chemical reaction of the catalyzed rubber can be arrested by freezing the material. This can keep material usable for weeks or months. To use again simply allow it to reach room temperature and apply.

Roof leaks repair with EPDM coatings

Roof Leaks Repair with EPDM Coatings Roof leaks repair with EPDM coatings is often recommended by professionals for many reasons. Here are the reasons to consider this type of liquid synthetic rubber for all of your roofing repairs. Cost Savings There are short-term and long-term cost savings. Repairing a leak is always less expensive than replacing the roofing material but most repairs are short-lived. The leak has to be repaired again and again. Leaky spots typically occur on flat roofs in areas where rainwater pools. Those spots are not going to go away easily. To completely get rid of them could require a complete renovation of the building. The best coating can last three times as long as other reparative materials. It lasts longer than acrylics and urethanes. Since you don’t have to make the repairs again and again, there is a significant long-term cost savings. Ease of Use Flat roof leaks repair with EPDM coatings is also recommended because of how easy it is to use. You can do the work yourself. You can hire a contractor or you can have your existing maintenance crew do the work. Complete instructions concerning temperature, application, coats, cure time and other important factors are included with the products. Basic application instructions include cleaning the surface and then applying the material with a rubber squeegee and a short-nap roller brush. You can use a standard paint brush for hard to reach areas. Noise Reduction+ One of the reasons people choose a rubber coating is to reduce noise. Noise from rainfall and other sources are reduced significantly because of the rubberized surface. Of course, this benefit is only realized when the material is used to cover the entire roof. If you are repairing a small section, you may not see this benefit. High Compatibility with Most Roofing Materials Roof leaks repair with EPDM coatings is a good choice for more roofing materials than any other kind of coating. The coating can easily be applied to metal, rubber, fiberglass, concrete, wood, fabric or foam. For asphalt and asphalt built-roofs, a special elastomeric coating should be used first. The rubber does not adhere directly to the asphalt. But it will adhere to the elastomeric coating. Some companies offer a 10 year warranty when the liquid rubber is used in conjunction with the elastomeric coating. Those are the main reasons that roof leaks repair with EPDM coatings is a good choice. The cost savings alone makes it worth your consideration.

Roofing and Factors for its Repair

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.

Roof leaks

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.

  1. 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.
  2. 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

Roof Sealants for Leaky Roofs

Sealers really are nothing more than a clear finish that has been altered to make it perform differently. What is added, or removed, from the finish determines what the sealer is and what it does. Primer, which is the sealer used with paints and pigmented lacquer, is basically paint or lacquer, that has an increased amount of pigment.

Roof Sealing

The sealant can be used for installation and maintenance of a roof made of shaped boarding or roof tile:

  • in places of isolation joints between open-ended exit points and roof sheets;
  • under ridgy planks and joints of a tent shape roof;
  • under a snow shield on a roof;
  • when installing the furring;
  • at lap seams;
  • at trough joints;
  • at a joint of a trough and a drainpipe;
  • at a trough end;

 

Sealers are capable of doing a lot more than simply stopping up the pores of cracks in any surface. They can be used as a barrier coats to seal in surface impurities like dirt, wax, silicon and natural oils and preventing them from leaking out of wood and through the finish. Sealers can act as bonding agents between two materials that may not normally adhere to one another.

 

Roof Sealers are bright white, reflective, elastomeric roofing solutions for roofs that are not yet ready to be torn off and are capable of being restored back to their original quality. EPDM, Modified Bitumen, Metal Roofs, Single-Ply, Polyurethane Foam, Smooth Built Up, or even Gravel Built-Up, we have a roof coating that can repair and restore your roof. Our roof coatings can even repair metal roofs to good as new condition.

Once water finds it’s way in through the gap and under the roof sealing material it works it’s way downwards and can be the cause of water leaks inside a building.  The water causes further condensation which is unseen and causes the steel sheeting to corrode.

Elastomeric Roof Sealants

 

Elastomeric roof coating is a 100% acrylic, highly elastomeric, titanium fortified roof coating formulated to provide a high solids rubber-like membrane. Designed specifically for use on metal, polyurethane foam, EPDM, APP, masonry, asphalt and wood surfaces, this elastomeric roof coating product forms a highly reflective barrier resulting in significant energy savings!

Boots, gloves, diving suits etc, have proven that rubber is the first impervious product that is totally waterproof. EPDM flexes and resists temperature changes, is totally resistant to atmospheric pollution, unaffected by UV light or ozone and extremely robust to puncture. Unlike bituminous substances it does not crack, peel or become brittle with age, which has been proven with its use in sub zero temperatures in the These facts make EPDM rubber flat roof membranes the best installing flat roof sealant to fix a flat roof structure. Ideal for flat roof contractors or do it yourself flat roof home restoration.

 

High-strength elastic roofing and sealing material consisting of at least one bonded fabric layer of organic material, optionally at least one further bonded fabric or bonded-fabric material layer of inorganic material, and a coating of bitumen on both sides, where the bonded fabric layer(s) is (are) impregnated with the bitumen, and where the bonded fabric of organic material has a certain area weight and a certain residual deformation after previous elongation. The bitumen coating optionally can be made elastic by the addition of modifiers with sufficiently low glass conversion points.

 

Other Roof Sealants

 

A number of other materials are used to provide an air barrier at different locations in the house. These include specialty gaskets and tapes, as well as sheet materials such as polyethylene, spun-bonded olefin, rigid insulation, drywall, plywood and sheet metal. Installation techniques are critical when using sheet materials as an air barrier. All edges, seams and penetrations in the sheets must be sealed.

Tips on Sealing Some of the Leakiest Areas

If you notice a draft through an outside wall electrical outlet, it must be sealed. (Some inside wall outlets can also provide leakage paths, so check them as well.) Turn off the power to the outlet by turning off the circuit breaker or removing the fuse. Check to make sure the power is disconnected by turning on a lamp.

You will obtain a better seal if you caulk the gasket before installation. Place child safety plugs in seldom-used outlets. Some foam pads come with a gasket that fits on the safety plug.

If you are installing an electrical outlet during a renovation, get a good seal by placing it in a special plastic box that is available from many hardware or electrical supply stores. Caulk the penetration for the wire, and seal the new air and vapour barrier to the edge of the box.

Planners and roofing companies still face a big challenge in finding an inexpensive, timesaving and durable sealing system for flat roofs on industrial buildings. Particular problems are presented by roofs with complex shapes and a large number of breakthroughs, such as airshafts and pipe supports. It is hard to get around these problems using conventional roof sheeting, especially as it is usually around the breakthroughs that the roof begins to leak.
