Frequently Asked Questions (FAQ)
Roof Surface
Q: My roof has drainage problems because ponds of water gather in low areas; can Dura-Foam fix this?
Q: Is it okay to walk on a Dura-Foam roof?
Q: Are Dura-Foam roofs slippery when wet?
Q: Do birds tend to cause problems by pecking at foam roofs?
Q: Can leaves and dirt be swept or washed off of a Dura-Foam roof?
Q: My roof has drainage problems because ponds of water gather in low areas; can Dura-Foam fix this?
A: Yes, low areas are located and filled with closed cell Spray Polyurethane Foam (SPF) during the roof installation process. This additional material is applied to low areas to displace major amounts of ponding water. Also, additional drains are installed if needed. On flat roofs we may recommend additional material to create positive drainage.
Q: Is it okay to walk on a Dura-Foam roof?
A: Yes. Walking on a Dura-Foam roof is like walking on a sidewalk. The surface is hard and durable. Dura-Foam roofs sustain heavy foot traffic and construction traffic without damage.
Q: Are Dura-Foam roofs slippery when wet?
A: Like typical floor surfaces, foam roofs are more slippery when wet. Caution should be used when walking near roof edges in wet conditions. Clean foam roofs tend to be less slippery. A dry foam roof is not slippery.
Q: Do birds tend to cause problems by pecking at foam roofs?
A: Dura-Foam roofs that follow our recommended coating upgrade guidelines maintain such a tough coating layer that birds do not peck at them. Bird pecking is rare on Dura-Foam roofs and usually only occurs on roofs that are way overdue for a re-coat. When the coating layer wears thin, birds are able to peck at weak areas in the coating and reveal the underlying polyurethane foam. Birds always cease to peck after these roofs are re-coated. Damaged areas do not leak unless the thick Spray Polyurethane Foam (SPF) layer is completely penetrated. Also, bird pecks are easily repaired with a polyurethane sealant that is available in caulking cartridges.
Q: Can leaves and dirt be swept or washed off of a Dura-Foam roof?
A: Yes. In fact, keeping leaves and debris off of the roof surface is recommended because it will keep the drains from getting clogged. Also, the coating tends to last longer and stay cooler on cleaner roof surfaces. Foot traffic, sweeping, blowing, and washing will not damage the roof.
