Spanish Tile Roof Installation Guide
A Spanish tile roof is one of the most attractive roofing choices when choosing a tile type covering for your home. Spanish tile boasts a classic look but is also provides a modern appeal as well. Spanish tiles are made of ceramic or concrete. While they traditionally come in two pieces, one piece tiles are available.
Selecting a Spanish tile roof will ensure that you have one of the strongest and most weatherproof structures available. Spanish tile is made of incombustible materials that will be hard to break under a low moisture absorption rate. You can install Spanish tile on your own with the right preparation, materials and instruction.
Step 1 - Install Underlayment
Before installing your tile, it is important to install the underlayment first. Underlayment will keep your roof waterproof and eliminate moisture between your roof and tile. While a 30 pound underlayment is most often used, your local building codes will determine which type of underlayment you should use.
Step 2 - Metal Flashing
Place metal flashing in the valleys, chimneys, and your skylights if any. Install flashing at any area your roof meets a vertical wall. Ensure that your flashing is a 28 gauge corrosion resistant material.
Step 3 - Cant Strip
With your hammer and nails, attach the cant strip to the eave of the roof. Ensure that it is flush. The cant strip will slant the first course of tiles so that it matches the remaining courses across the entire roof.
Step 4 - Measuring
With your tape measure, measure from the roof eave to the length of your tile and make and use your marker on the underlayment. Your tiles will need a 1 inch overhang and the eave and a half inch head lug to the rear of your tile. Subtract 1-1/2 inches from your first mark and make another mark on the underlayment. You will need to do this at the other end of the roof as well. Once you have completed these measurements, use your chalk line to mark the points.
Step 5 - Placing the Batten
You will now need to install the batten just below and flush with the chalk line. After your initial installation of the batten, you can now measure and mark the rest of the roof and install the batten. These lines will need to be 3 and 1/2 inches from the length of the tile.
Step 6 - Install Tile
You are now ready to install your tile. Ensure that you lay the tile from a left to right direction. The vertical interlocking joints of your tile must not be obstructed by any debris. Otherwise, the tiles can not be seated properly. You will need nails to secure the tiles to the roof and how many you will need depends upon the degree of your roof slope. You can consult your local building codes to determine the number of tiles that need to be secured by nails.
