With this informational video, you’ll learn the best ways to install Quarrix Composite Roofing. 

Many homeowners love the look of clay tiles but want the benefits of a lightweight roofing tile. Quarrix’s Composite Roofing line offers them the best of both worlds! But when it comes time to install these tiles, you need to properly prepare the roof deck to ensure the roof will perform as it should. That’s why Quarrix has a handy video about how to prep a roof deck before installing composite roofing. 

Brian Knight, installation expert at Quarrix, breaks down exactly how to prepare a roof deck to ensure it lasts for decades. He states that you should read the installation manual alongside the video to get the full picture of how to install these tiles.  

First, you must remove all the roofing materials, then make sure the decking has a thickness of 15:32 or greater. From there, you must install an ice and water shield underlayment from around the eaves, valleys and penetrations to ensure proper roof waterproofing. Then on the bulk areas, install a synthetic underlayment, covering all horizontal seams a minimum of three3nches and end laps a minimum of six inches. Finally, overlap all metal flashing for a watertight seal. 

Although these tiles can be installed direct-to-deck, Quarrix recommends using their batten system. This system maintains tile alignment across the roof and speeds up the installation process. It also helps moisture and air flow through the roof easily, which creates a cool roof system. 

The first chalk line for the batten is 15 ¼ inches away from the eaves. Make sure when the tile is installed that it doesn’t sit over the edge of the roof, but rather is supported by the drip edge of the roof. After determining where the mark is, snap the chalk line into place and install the batten there. For the top batten, measure one inch off of the ridge to find the line for the top batten.  

Once you have the top and bottom battens installed, you can measure the line for the center battens. Measure the distance between the top and bottom battens. Divide the sum between the two into equal increments, but never more than 13 ½ inches.
