SPF roofing provides a complete water proof surface. Your new spray foam roof is one solid monolithic roof because there are no seams involved with SPF roofing as there are with other roofing materials. Modified bitumen roofs are giants rolls of membrane laid out and torched down with an open flame to bind the material together to provide a seal. Same applies with TPO roofing applications. The seams on a TPO roof are bound by a heat welding machine. One thing we all know is that if you have seams involved in a project, they will fail. Eliminating all seams is one huge advantage that will provide years of weather resistance you simply cannot find with other roofing materials.
Some other advantages to using foam roofing applications is its ability to provide a complete air seal for your home as well as adding excellent R-value. This dramatically increases the overall comfort of your home. With an average R-value of 7 per inch you can reduce the expense of adding materials to increase the insulation if your home. Most TPO roofers will advise you to use foam sheets below the TPO membrane. There are two reasons for this recommendation. First there is a constant risk for tearing the membrane while walking on the roof to service an A/C unit. Second they will advise you to install the foam to provide any needed insulation. The foam sheets are pieced together providing more seams to deal with. You can rest assured that your monolithic SPF roof is the best solution to provide a seamless efficient roof that will provide added comfort while continually putting money back in your pocket year after year.
A built up roof is one of the most common roofing applications used today. It consist of multiple layers of tar mopped on top of your home and then covered with aggregate rock. There are added expenses needed to build crickets or slope when you have a true flat surface to work with. There are known issues with the performance of tar especially in colder weather. The tar can crack as the cold weather constricts the material during winter months. The typical pea gravel added on top of a BUR can restrict water from draining properly leaving standing water on top of your roof. This standing water can freeze in the winter months putting more stress on the tar and accelerating the degradation of the roofing system. When you choose our SPF roofing system you eliminate thousands of pounds of weight off your structure eliminating much un-needed stress on the structure. For most leaking BUR’s we can provide our spray foam roof over the existing roof eliminating any tear off costs associated. We will remove all loose gravel and completely seal the existing roof with the lowest maintenance possible.
TPO roofing is a newer system many people are interested in. Many people are drawn to then by claims of lifetime warranty. The hidden truth behind this claim should be taken into consideration. First off TPO roofing is a little over a decade old. There are multiple materials bonded together to create the rolls of TPO applied to your roof. We are currently in the second generation of TPO roofing. The first generation had many documented issues with seams failing and the rubber material breaking down to the UV exposure from the sun. In fact many manufacturers pulled all existing TPO material out of the market to reevaluate the procedure of manufacturing to address the issues. The needed changes were made and the current generation of TPO roofing was born. One major issue is the limited time of existence that these products have been in the market. There is very limited information on the performance of the TPO material due to the fact that this is simply a reformulated product that manufacturers are hoping to provide better results than the first generation.
