How to Install Clay Tile Roof Flashing

What You'll Need
Cant strips
Underlayment-waterproof membrane(optional) and builders felt

Clay tile roof is made from baking clay and molded into tile. It is lighter in weight as compared to concrete tile roof at the same functions just like a concrete tile with its ability to withstand fire. It is one of the oldest methods used as a finished covering on roofs.

Step 1 – Install the Underlayment

Underlayment is an important structure for clay tile roof. It acts as protection against water that will seep through the tiles. It also protects the roof from leaking and acts as a sealant on the roof. Install a waterproofing membrane on the roof particularly on areas where there is high probability that water will seep. It is usually made of a thick material and can be expensive, but it adds extra protection against water leakage.

Install the builder’s felt or tar paper. This is the commonly used underlayment made from thick material. Roll the felt and staple or nail it on the roof. Once you have successfully installed the felt, your roof will be able to withstand water and heat.

Step 2 – Install the Roof Flashing

Use a flashing for your clay tile roof to prevent any excess rain from running to another direction. Place it on specific roof areas where water will likely pass through such as the valley, chimney or skylight. Secure it in place using a nail and cant strips. Construct the flashing using durable and stainless steel materials to prolong its life span. The drip edge is the corner-shape metal strip attached on the roof edge which routes the rain flow away from the edge. Secure the drip edge beneath the builder’s felt to protect the felt from extreme weather.

Step 3 - Attach the Clay Tile Roof

Lay the tiles down in a left to right path as a result of the vertical keyway connecting the tiles. Make sure to clear the area where the joints interlock vertically to ensure smooth process and proper fitting of tiles. Position the tile in such a way that the head lug located at the tile’s rear must be at the back of battens. The quantity of clay tile roof to be used will depend on the slope of the roof. Do not use foam adhesives to attach the tiles because it provides a weak attachment.

To improve the appearance of the roof, paint the flashings similar to the color of the fascia. Protect the clay tile roof material by keeping it dry until its usage. Do check for moisture on delivered roof materials to avoid deterioration. It is important to keep all the materials dry.

Installing clay roof tile flashing may seem quite easy to look at but it is actually tedious. Spend some time to learn more about flashing together with an experienced craftsman. Once you gain learning from the professional, you may begin to do it in your own way.
