It is very important that you establish a base-line condition of each roof system you own or manage and know the overall condition, life expectancy and defects. This information is needed for budgets, planning, capital, and maintenance projects. At RPC we are experienced in offering you detailed inspection reports that outline the needed work and provide an expected budget for those repairs. Although a visual inspection is an important inspection to establish or maintain a base-line understanding of your roofing system, it is limited to only what is visible to the inspector.
Spray polyurethane foam roofing systems are constructed by spraying a two-component liquid that forms the base of the adhered roof system. The mixed liquid expands 30 times its original volume in a matter of seconds, forming a rigid foam plastic that chemically bonds to the surface to which it is sprayed. The closed cell structure of the foam provides the waterproofing, but must be protected by coatings or other coverings to prevent UV surface degradation. SPF can be installed in various thicknesses to provide slope to drain or meet a specified R-value.
