Spray Foam Insulation Chicago discusses their Dos along with Donts for Prepping a Roof Substrate Ahead of a Spray Foam Roofing System Program – Sustainability, energy usage reduction, outstanding R value into the construction, improved wind uplift resistance the advantages of a spray foam covering systems are well cataloged through the years to the stage where, in a lot of cases, a SPF roof sells itself. Nevertheless, the system is just as good as the contracting firm that matches it, and there is the degree of dedication and experience that divides their men from their boys, so to speak. Though the roof system installation chiefly contains the use of spray polyurethane foam along with a protective coating, the groundwork of the substrate is a critical and equally significant portion of the overall project.
Not doing so could cause an insufficient substrate preparation which could undermine the integrity of the installation and finally generate a roofing system of sub par performance, regardless of the numerous advantages SPF boasts. A CLEAR, DRY SURFACE – possibly the most necessary requirements for a proper SPF roof setup is using a dry and clear roof coating. A major trap resulting in an under performing SPF roof program is derived from materials installed over a coating that’s not 100% smooth. Debris, but even more important, humidity on their roof can result in an improper yield of their SPF to their substrate, as well as lead to shrinkage and generate pinholes from the end product.
The first consideration a contractor must comply with is checking to see if their roof is totally dry, SPF roof specialist Manuel Adler Majority of Purefoam Insulation said. If foam is installed over humidity, their entire project has already gone wrong. If sunlight is inefficient in drying the substrate, contractors may have to resort to mopping, utilizing a back pack blower, or a torch their latter being applicable just in the gravest of situations. As far as debris goes, their crew can either Collect their residue in piles using brooms along with dispose it in trash bags, very clear the roof by way of a back pack blower, or power wash their substrate and wait around for it to dry before the use of materials gets underway.
DETAIL WORKING AND PRIMING – Detail work varies from roof into roof. Frank Nestle, a SPF and coating roof specialist along with representative from Accella Roofing Solutions explained that if these areas aren’t reinforced, a potential risk for movement inside the roof system is created. This often leads into an eventual split or puncture that might cause the entire roof program to fail. If an open seam isn’t repaired prior to their SPF application, their program might not be powerful enough and the chance of a split happening in their future is Significantly enhanced, Nestle said.
