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. 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. 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. 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 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 consid-erably 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 work¬ing 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: restora¬tion and re-cover. 1. EPDM roof restoration usually encompasses reworking the flash-ings, seams, and terminations, while leaving the field membrane in place. EPDM is well known for its long-term wea¬therability, so in most cases the field mem¬brane has life remain¬ing. 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 restora¬tions. Proper drainage, thermal bridging, en-hanced R-value, al¬tered surface color, as well as enhanced wind uplift and hail resis¬tance, are all issues that are better ad¬dressed with a roof re¬cover.

An 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.
Common Types: acrylic elastomeric coating, butyl elastomeric coating, silicone elastomeric coating and urethane elastomeric coating.
Roof Restoration Process
Pressure wash the entire roof surface to remove all dirt, dust, previous paints and coatings that are delaminating and achieve a clean and sound substrate. Some roofs may require special detergents. Call us for recommendations.
Prime the roof to ensure good adhesion of all coatings. We have primers suitable for almost all roof types. Even totally rusted roofs.
All seams, penetrations, non-structural gaps and parapet walls should be flashed. All fasteners should be sealed or capped with elastomeric caulk.
Inspect the roof for defects or flaws. Apply the elastomeric coating to the entire roof surface to produce a seamless, watertight membrane.

Concrete which has not been trowel finished will have a surface that is more porous than one which has been trowelled. When Liquid Rubber is applied directly to such a porous surface it will produce a high density of small craters in the resulting membrane. This is caused by the fact that Liquid Rubber actually penetrates into the pores, leaving a crater on surface . The following procedure is recommended to prevent formation of surface craters:
1) Apply a light coat of one of the following products to seal the surface:
a.) Water based acrylic elastomeric roof coating( primer or base -coat version)
b.) Solvent based chlorinated rubber or Hypalon product.
c.) Solvent based neoprene product.
The choice of water or solvent based product should be based on temperature and humidity conditions. For water based products, relative humidity should be less than 70% and temperature 60 degrees or higher. Solvent based products should be used at low temperatures and high relative humidity.
2) Liquid Rubber may be applied when primer application is sufficiently dry. Water based products should be allowed to dry thoroughly, as any surface moisture will interfere with the adhesion of the rubber. A single coat of Liquid Rubber is preferable to multiple coats.
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.
