SEARS ROOFING

Roofing Size: 745 Squares

Project Valuation: $855,000

Once the gravel vacuum team was able to arrive on sight the removal of ballast stone was complete in just two days. Once the vacuum team began our roofers initiated loading the roof to counter balance the areas where the ballast stone was being removed. The previous system was a loose laid EPDM membrane over a single layer of three inch polyisocyanurate. Our crew had to be mindful of the previous system because if the proper counter balance was not achieved the roofing system in place could bridge and blow away quite easily.

Once the gravel vacuum team was able to arrive on sight the removal of ballast stone was complete in just two days. Once the vacuum team began our team began loading the roof to counter balance the areas the ballast stone was being removed. The previous system was a loose laid EPDM membrane over a single layer of three inch polyisocyanurate. Our crew had to be mindful of the previous system because if the proper counter balance was not achieved the roofing system in place could bridge and blow away quite easily.

We first removed the EPDM membrane rolling it into manageable sized rolls and carting over to the crane for lowering and disposal The existing polyisocyanurate was stacked, wrapped and lowered. The insulation was trucked off and donated to a local charity for use on a community building and reducing waste to the landfills.

The deck was inspected and then the insulation was installed. We used two layers. The lower level installed was 1.5” and the top layer of 2” was seam staggered and secured to avoid thermal bridging and reduce energy loss.

We then installed a 1/2” Securock board which adds greater fire resistance and offers a severe hail rating.

Our system installed was a 60ml TPO membrane, mechanically fastened over two layers of H staggered polyisocyanurate and Securock. The parapet walls were fully adhered and the metal copings were replaced with Hickman Engineered metal systems dual cleat panel. By enhancing the perimeter sheets and following design criteria by Versico we were able to achieve a 90mph wind rating on the entire roofing system.
