When considering various roofing systems, one system you should look at is a concrete tile roof. This will be especially applicable if you live in a climate with more extreme weather and climate conditions. However, if you plan to install your own concrete tile roof, reviewing common mistakes that you should avoid will likely make your installation more trouble-free. Below you will find information on some of the more likely mistakes you should avoid.
Local Building Code Violations
Before you take your first step in planning for installation of a concrete tile roofing system, don't fail to check local building codes. If you proceed without an understanding of these codes, you could be in violation and could be forced by law to remove your system. Your best move would be to check with the proper local government agency for details of building codes related to roofing construction.
Manufacturer Application Instructions
Even if you have some general knowledge of roofing installation procedures, each system is likely to have application procedures that are different from other systems. Proceeding without understanding these differences could result in failure of your roofing system. Don't proceed with your installation until you've read and have a good understanding of manufacturer's application instructions.
Adequate drying time for the system's adhesive is essential for the success of installing this type of roofing system. This means you will need warm, dry weather for at least two days when you begin your installation. Don't take chances. Check with dependable weather forecasting to make certain when you can install your system in warm dry weather.
Tile Installation Patterns
The key to creating a waterproof roofing system with concrete tiles, is in the patterns you use to install these tiles. Improper tile installation will result in failure to create a waterproof system. Avoid using any installation pattern except that which is prescribed. For a slanted roof, lay your first row of tiles along the bottom edge of your roof on both the front and back slopes. Then, work upwards along the roof surface to the roof peak. On a flat roof, begin installing your tile at the outside edge of the roof and work inward toward the center. As you progress up the roof with each tile row, be sure lower edge of each tile laps over the upper edge of the tile above it. Following this procedure will insure that water will drain off the roof properly.
Tile Mortar Application
Don't overlook the necessary application of mortar to the outer ring of roof tiles. Before laying each tile, apply your mortar to the underside of each tile and use a serrated trowel to distribute the mortar evenly.
Adhere Center Roof Tiles
At the roof center, apply concrete tile adhesive or asphalt roof cement to tiles in the center portion of the roof, using the same overlapping process as described above.
Center Roof Tile Installation
At the roof center where tiles from opposite sides of your roof meet, apply mortar to the bottom surface of V-shaped tiles and place these tiles over the narrow space between the tiles that come together.
