What an incredible year! We are in the peak of Summer and just getting ready to start another high profile commercial roofing project. Many of you know James Hardie, one of the most prominent siding manufacturers in the Nation. Our firm has been selected to perform the installation of a new single ply retrofit roofing system. This project is due to kick off the week of September 11th, 2017. We are limited on types of pictures we are allowed to take but for the sake of showcasing the assembly we will use "like systems" to provide pictures, and information. We are excited to be chosen as the commercial roofing contractor to partner with one of the Nations leading manufacturers in the construction industry.
What Is A Retrofit Re-Roof
There are many ways to waterproof a roof. In some cases a temporary solution is sought out to prolong the cost of a complete re-roof. In the commercial industry "recovers" are a common and cost effective way to install a more permanent waterproofing solution. It's common to see an additional layer of torchdown burnt onto an existing built up or torchdown roof or a single ply membrane installed over similar systems. A newer recover system that is becoming very common in the industry is an overlay over metal roofing. This requires a particular system in order to achieve the correct result.
The first step is to generate a custom piece of "flute filler." Flute filler is made of EPS, a type of styrofoam if you will, that fits exactly in between the ribs of the metal roof. When you "fill" the cavity of the metal roofing panels you end up with a smooth flat substrate to install your roofing system on. Insulfoam is a prominent EPS manufacturer in Puyallup, WA, and the company we have selected to provide our product for this project. EPS provides very little "R" insulation value, but is very beneficial for creating a separation layer between substrate and roofing membranes.
