Some home and business owners have chosen to coat their roof instead of removing the old roof and replacing it with a new one. In certain circumstances, this is a cost effective option that produces better results. Houston roofing professionals can perform a roofing inspection to help residential and commercial building owners determine if this is the right option for their structure. Roofs must meet certain specifications in order to qualify for a roof coating as opposed to a reroofing job.
Asphalt shingles are not designed to be coated, but just about every other style of roof can be. The roof must be in good enough condition for the coating. This procedure is most commonly performed on metal and single ply membrane roofs that are flat or have a lower slope. These would include roofs that have a smooth modified bitumen membrane or a PVC membrane.
There are many benefits to coating a roof as opposed to reroofing. Cost is the primary benefit. Metal roofs and other roofs that are made of materials that can be coated use premium roofing materials that are expensive to replace. In many counties, coatings can be applied without building permits. This helps reduce repair cost.

Acrylic coating can be used as a stand alone roofing system. In some circumstances, coatings can be applied directly to a plywood roof sheathing. Aluminum coating is preferable in many situations because it will not blow off, and it is light enough that it can be laid over an old roof without any weight concerns.
Higher end roof coatings come with a 10 to 15 year warranty from the manufacturer. Some manufacturers will even send representatives out after 10 years to evaluate the coating and determine if it is a viable for another 10 years.
Whether the decision is to coat the roof or to reroof, it is best to first speak to a professional contractor. During their roof inspection, they can identify areas that may require maintenance and repair. Doing this will guarantee that the roof has a happy and long life.
