The best way to extend the life of the roof is to apply a roof coating to the surface, these come in a few different types. There is asphalt based and polymer or elastomeric based coatings available today. Both can extend the life of your roof but the elastomeric roof coatings will give you a better quality roof surface.

Roof Coatings Phoenix Talks on Flat Roof Coatings

Asphalt Based

A black modified asphalt based coating formulated with fillers and fibers will form a tough but elastic film upon curing. This type of coating will seal small cracks, joints, seams and voids, however, these types of asphalt coatings are not UV stable and will typically require a UV stable elastomeric topcoat. These modified asphalt coatings have the ability to penetrate, resaturate, and revitalizes sound roofing materials while it’s elastic skin prevents underlying commercial roof felts from becoming brittle and cracking. The elastomeric topcoat is resistant to water and heavy bodied enough to eliminate running on a sloped roofing surfaces. There are also aluminum coatings that are available that can be utilized in lieu of elastomerics to give a certain level of sunlight reflectivity to help reduce the roofs overall surface temperature thus saving you money on your cooling expenses and keep costs to a minimum. A modified asphalt coating will also provide a tenacious bond to existing asphalt based roofing systems when roof restoration systems are being considered with acrylic coatings.

Elastomeric

Elastomeric commercial roof coatings are generally acrylic or urethane based and come in a liquid form. Roof Coatings Phoenix says they are white in color but can be mixed with colorants to obtain a desired look. Quality elastomeric roof coatings have low dirt pick up and excellent ponded water resistance and long term UV stability. Both of these types of coatings will give you a seamless roof surface and should be leak free if the coatings are applied correctly. Commercial roof coatings do not work alone, there is a lot of prep work that must be done prior to applying the coating. Fasteners need to individually sealed and seams need to be reinforced if your coating a metal roof, flashing’s need to checked and reinforced and you need to start with a clean surface which that alone can take some time to complete.

Contemplate coatings

As you can see there is a lot to consider when choosing a commercial roof coating solution, if you are unsure you should contact Roof Coatings Phoenix. The condition and age of your roof are very important to consider as well because some roofs are too far gone to be saved by coatings and will need to be torn off. The best way is to have your roof inspected by a professional, but a good indicator is walking the roof and feeling for soft areas where water has penetrated through the commercial roof and damaged the underlying insulation and deck. In many cases these bad areas can be cut out and repaired with traditional roof materials and then the coatings can be applied. The surface of the roof is a good indicator as well, if the surface of the commercial roof is very brittle and cracks while you are inspecting then most likely the roof would not be a good candidate for a roof coating.
