You may well have been told about the virtues of spray polyurethane foam roofing by a colleague, family member, or friend. In which case you’ll know that it forms a seamless layer with a very high R-value, and that in most circumstances, you won’t need to remove any material from your existing roof.
Here, we’ll briefly look at the different forms of commercial roofing and see how suitable foam roofing is for each of them:
Metal roofing
Metal roofs can very easily be covered with spray foam. The existing roof surface must first be cleaned using a power washer to get rid of any dirt and debris. A reputable commercial roofing contractor will apply a UV activated, black primer to absorb dirt dust & debris after pressure wash and before the SPF application. The SPF foam will stop all rust once applied, no need for an inhibitor.

EPDM roofing
In some cases spray foam is suitable to apply to existing EPDM roofing, however, generally an EPDM roof needs to be removed. EPDM is not attached fully to the substrate, so the foam will pull it away when it’s curing. There are three distinct methods of application for EPDM roofs, and which precise form of EPDM roof you have will impact how your new spray foam is installed.
Built-up roofing
A built-up roof with either a smooth or graveled surface is suitable for SPF foam application too. Before spray foam is applied to graveled built-up roofs, any loose stones and gravel must first be removed using a commercial dry vac or shoveled & brushed, then primed to ensure a good bond.
