Solutions for a Failed Foam Panel Roofing System

Foam Panel Roofing System

• A foam panel roofing systems consists of structural insulated panels, or SIPS, made from foam plastic and board materials. A single panel contains a rigid foam plastic core encased in two oriented strand boards made up of pressed wood strands, or flakes. The foam interior acts as an insulation material that helps to protect and preserve the roof surface. As different roof designs may require different-sized panels and layouts, manufacturers can customize foam panel designs to suit different roofing requirements.

Installation Process

• Foam panel roofs should function as complete sealed systems that prevent heat and moisture from damaging roof surfaces. The proper installation of a panel roof system entails using foam sealants to close up any gaps or crevices between paneling and other roof structures, such as metal siding and chimney areas. The actual handling of panel materials also may require the use of special equipment for larger-sized panels to ensure proper placement and setting. While small roof installations may not require the use of professional installers, a certain amount of expertise can help ensure a sealed roofing system.

Insects

• As with any other type of wood construction material, the strand boards used to encase a panel’s foam interior can attract termites. Over time, potential insect problems can develop to the point where a foam panel roofing system begins to deteriorate. In effect, termites can hollow out panel sections and use these areas as nesting grounds. Purchasing foam panel materials manufactured with borate-treated foam can help ward off the likelihood of termite infestation. Another option involves using a special steel mesh material that prevents termites from boring through panel sections.

Mold & Mildew

• When a foam panel roofing system develops cracks and gaps along panel sections, moisture access can cause mold and mildew to form. Over time, panel sections may begin to deteriorate as mold and mildew spread. Panel sections may show different degrees of deterioration, with some panels having only surface damage, while others develop cracks or a softening of board surfaces. Applying sealant in moisture access areas can help alleviate surface and structural damage problems. Panels that show significant structural damage will likely require replacement.
