If your spray foam roof is maintained well, it could last for many years. Good maintenance involves putting on a new coating when it's needed since the old one wears off gradually. A coating protects the foam from UV rays and keeps water from seeping through the roof. Periodic sealing of a foam roof is one of the more important commercial roofing services. Here's how it's done.
Inspect For Damaged Areas And Water Intrusion
The commercial roofer checks your roof for areas of damage from hail impacts, birds pecking, and foot traffic. These areas are marked so they can be repaired. They may also use a thermal camera to check for water damage. If the foam has water damage because the old coating already wore off, the roof may need to be replaced.
Make Repairs On Holes And Cracks
If holes are found in the foam, these should be repaired. Damaged areas can be cut out of foam roofing once the roof has been cleaned. The roofer has to make sure they don't affect the slope of the roof and keep the roof from draining properly. If they do, they'll need to restore the proper slope when the holes are filled.
Once the cracks and holes are cut out, the damaged area can be filled with caulk and the edges smoothed over. Repaired areas are also covered with a coating to protect the repairs.
Apply A New Coating
If the roofing contractor didn't clean the entire roof before making spot repairs, they'll need to clean the roof thoroughly before putting on a new coating so the new coating bonds well. They might use a pressure washer to get rid of dust, pollution, and debris. The roof has to dry thoroughly before the coating can be applied.
A new roof coating can be sprayed on the roof covering a section at a time while being sure not to miss any spots. Roof coatings are often made of silicone, so the roofer needs to follow the manufacturer's instructions for applying silicone in the proper temperature range.
Applying a new coating is a fairly easy process, but it can take a long time if you have a big building. When the coating is dry, it will protect your roof from UV damage and water for several more years. However, it's still important to have maintenance on your roof regularly. A commercial roofing service can make regular visits to do inspections and maintenance so you won't have to worry about water damage ruining your foam roof.
