SPF Roofing Installation and Maintenance
How it's Installed
SPF roofing systems are installed by trained applicators who understand the spray equipment, the foam and coating materials, and industry roofing practices. After careful evaluation of the roof deck condition, the roof deck is prepared by removing debris and optional application of a primer to improve adhesion. A specified thickness of SPF is applied followed by a protective covering.
SPF roofing systems include a covering to ensure protection from the effects mechanical wear, UV exposure and other weathering processes. The SPF can be covered with a variety of cool roof elastomeric coatings or aggregate materials which can:
- Inhibit moisture vapor transmission
- Enhance aesthetics of the system
- Increase the impact, chemical, and abrasion resistance of the system
- Satisfy fire resistance criteria and code requirements
Elastomeric coatings are typically specified by the foam supplier as part of a SPF roof system and can include acrylic, silicone, butyl rubber, polyurethane and polyurea.
Simplified Maintenance
With regular care and maintenance, a spray foam roof is expected to last 40 or more years. Best practices call for SPF roofs to be inspected bi-annually and after severe weather events. For comprehensive guidance on SPF roof maintenance, see SPFA-127 Maintenance Manual for Spray Polyurethane Foam Roof Systems, available for download from the SPFA Online Store.
