Roof recover systems include TPO Roofing, PVC Roofing, EPDM Roofing, Fleece-backed Systems, roof coatings, and sometimes Modified Bitumen. These can be applied over existing assemblies, as long as building codes are met, saturated insulation is removed, etc. Because the original assembly is left in place and the cost for labor and disposal of the primary roof system is reduced, recovery systems can be a cost-effective option.
Roof coating systems are also a viable recovery option when properly planned and installed. These are recovery applications which provide resurfacing to an existing roof system. Certain criteria must be met for Roof System Coatings to be an effective and long-lasting option for commercial low-slope roofing systems.
