Roof Repair Systems

General Roof Repairs

• Over time, many roofs can develop leaks from deterioration of the materials by the elements. Asphalt can develop tears and holes. Metal roofs can develop enlargement of the holes around fasteners. Clay tile roofs may loosen and separate. These problems can be resolved with regular inspection and repair of the roofing materials. If necessary, a repair system such as a coating or membrane can be placed over the roof to stop leaks and further damage of adjacent roofing structures.

Gravel Repair Systems

• Gravel roofs in particular tend to develop leaks over the years. A repair system can be applied to extend the life of the roof for a longer period of time. All loose gravel is removed from the roof and the area is thoroughly cleaned. Any defect is the material must be repaired before a polyester or glass membrane is applied, according to the TremcoRoofing website. This process is generally done by roofing contractors that specialize in gravel and tar roof repair systems.

Elastomeric Roof Coatings

• Elastomeric roof coatings are made of a number of different materials that have characteristics of flexibility and waterproofing for roofing repairs. They generally are made of acrylic, butyl rubbers, chlorosulfonated polyethylene rubber or polyurethane compounds. They are applied as a film, either thick or thin, depending on the product, which seals the roof materials. Often, these are used in light colors to provide solar reflectivity for “cool roofs” that help to keep building interiors cooler and reduce energy costs. Elastomeric coatings can be used on a number of different materials, including asphalt, metal, rubber and bitumen roofs.

Coatings for Spray Foam Roofs

• Foam roofing starts out as two liquid compounds, an isocyanate and a resin, that are mixed at the spray gun and applied in layers to the roof. It then expands and dries for a seamless solid roofing material. Roof repair systems for foam roofs are generally elastomeric coatings, such as those mentioned above that have high reflectivity and high thermal emittance. They generally contain acrylic, butyl rubber or urethane compounds.
