How to Install a Tile Roof Part 2 of 2
Clay tiles give homes a truly impressive roof that can’t be imitated by other materials. The S design makes installation easier and less time-consuming. Each tile simply overlaps the preceding tile.
Modern clay tiles use an S-type design rather than the two-piece system that was once common. This simplifies the installation process and saves you time. Due to the contour of the tiles, you’ll need plumbing vents and air vents that match the shape of the roofing materials.
Before starting the project, make sure your roof framing can support the weight of the tiles. The materials are very heavy, and roofs designed for asphalt shingles may not have the structural support for clay tile. Check with your building inspector if you’re unsure.

Mark roof vent locations between rows of tiles and between rafters. Follow manufacturer’s guidelines for the size of the opening. Cut out the opening using a jigsaw or circular saw. Tip: Periodically look at the roof from the street to make sure the rows are running straight and the tiles look uniform.

Apply roofing sealant along the bottom of the primary roof vent, then install it over the opening using roofing nails driven every 4" through the flange. Seal the flange with peel-and-stick flashing. Place the secondary vent over the primary vent and nail it to the roof. Overlap the lip with the next piece of tile.

Center ridge tiles over the hips and peak. Apply a small amount of plastic cement on the nose of each ridge tile. Overlap the tiles for a 16" exposure, placing the tile over the plastic cement on the previous tile. Nail the ridge tiles using two nails per tile. Fill the gaps beneath ridge tiles with mortar.
