Closed-cell sprayed polyurethane foam (SPF) is composed of two liquid components - isocyanate and a resin (or polyol) - that are pumped from separate containers and mixed in the nozzle of a spray gun at a 1-to-1 ratio. Upon combining them, a chemical reaction takes place and the mixture expands 20 or 30 times to form a solid, lightweight, monolithic closed-cell mass. When sprayed on a roof deck, it provides a roofing membrane with excellent water resistance and thermal insulation.

Your tar-and-gravel roof is a good candidate for a commercial foam roof system. The new roof can be applied over the old. Before the foam roof system is applied, all loose dirt and gravel must be removed and hauled away. The tar membrane must be secured to the roof deck. Deteriorated edge flashing and vent caps must be replaced. And low areas must be identified so they can be built up.

SPF commercial foam roofing spray is applied in a series of passes. Each pass is a single application of foam that can vary from 1/2 to 1 inch thick. Multiple passes are made to build up SPF roofs to the desired thickness.

Foam roofs are strong and durable. They can handle foot and construction traffic as well as other roofs. But SPF decomposes in the sunlight and dents easily, so it needs a protective elastomeric top coat. Elastomeric means that the coating must be able to stretch and return to its original shape.

Top coatings are sprayed on and can be acrylic, silicone, butyl rubber or various urethanes. Coatings are usually installed in three stages: a base coat, a midcoat and a final coat. Granules can be embedded into the mid- and top coat or only the top coat for added protection against UV and mechanical damage and to increase the system's fire resistance.

If properly maintained, commercial foam roofs are long lasting. There is some maintenance, though. Every 10 or 15 years, depending on the type and amount of coating installed, the roof will need to be cleaned, primed and recoated. If this is done, then a good-quality SPF commercial roof could last 50 years or longer.
