Installing concrete tiles to manufacturer specifications begins with preparation of the roof deck, which should be clean, dry, and free of any old roofing materials. Next, a high-quality underlayment should be applied to provide extra protection against moisture. The tiles are then laid starting at the eaves, aligning the first course carefully because a straight starting point ensures proper overlap and alignment throughout. Each tile is typically secured with nails or screws in designated areas, which the manufacturer specifies to prevent cracking or loosening. Proper spacing between tiles allows for expansion and contraction due to weather changes. Interlocking edges or overlaps must be followed exactly to maintain water resistance and avoid leaks. Ridge and hip tiles require special attention, including additional fastening and the use of sealants or mortar where indicated by the manufacturer.
Before starting, it’s wise to do a simple check by comparing your installation steps with the written guidelines and diagrams provided by the tile manufacturer. Inspect the tiles for any visible defects or damage prior to installation, and ensure your tools and fasteners match the specifications. If you’re unsure about any step—especially the fastening pattern, underlayment selection, or tile alignment—it’s best to call a professional roofer with experience in concrete tiles. When talking to a contractor, ask, “How do you ensure the tile fastening meets manufacturer requirements to maintain the warranty?” and “Can you explain how you handle ridge and hip tile installation to prevent leaks?” These questions help ensure your roof is installed not only safely but also in a way that preserves the manufacturer’s warranty and the longevity of your concrete tile roof.
