How Is Tile Roof Installed
The tile roof is installed in multiple ways. When installing concrete roof tiles, the level of wind exposure a home or commercial project is subjected to will determine what fastening methods should be used.
If your certified roofing contractor has presented you with the option of choosing either mechanical fasteners or foam, then the choice is ultimately yours! Here are a few key points of both options to help you decide.
Foam
Foam is a lightweight fastening option that provides strong adhesion without penetrating the roof and facilitates more excellent walkability on the roof due to the “cushion” that the foam paddy provides. This lessens the risk of cracked tiles.
While wind resistance is improved using foam, it is a more expensive alternative to screws and nails, and some building codes do require that the first row of tiles is mechanically fastened as well. This is because tile roofs tend to fail around the perimeter where wind uplift is more severe.
Mechanical Fasteners
A less costly option, screws or nails are commonly used to fasten concrete roof tiles to the roof decking. Your roofing contractor will decide which should be used for your specific project, as this also depends on the wind exposure.
Compared to nails, screws have the advantage of not backing out and have more vital holding abilities. Screws also self-seal as they’re driven down through the decking and underlayment.
Hybrid Roof System
Applicable to all concrete roof tile profiles, a Hybrid Roof System is achieved using both a single-component polyurethane roof tile adhesive and mechanical fasteners, such as screws. Using these in conjunction with one another significantly increases uplift resistance compared to being installed independently.
Tests also show that this roof system produces wind uplift values nearly as high as those of a two-part foam adhesive application, but at a lower cost and with an easier, faster installation.
