SPF (spray polyurethane foam) roofs have been around for over 50 years. Foam roofs offer excellent insulating properties and an expected service life of 15-20 years depending on the level of maintenance. The long-term issues affecting foam roofs are: must be coated initially and re-coated over life of the roof to eliminate UV exposure to the foam; UV exposure can break down and damage the foam roof; punctures in surface coat can allow water penetration; and a limited installation window with temperature and humidity which can determine the density of the foam and greatly decrease insulating properties and adhesion to substrate.
Thermo Manufacturing can provide a long-term, sustainable solution for difficult roofing conditions. The links below cover our standard recommended systems for Foam roofs.
If actual project conditions are such as to be outside the scope of the normal waterproofing practices that are referenced in the documents below, steps should be taken to ensure the restoration remains in compliance with nationally recognized waterproofing practices such as those found in the National Roofing Contractors Association Manual. If the system is applied according to our published specification and guideline, and after successfully passing a final inspection, and then accepted by Thermo Manufacturing Systems, LLC, the system would qualify for the specified warranty.
