Sacramento Roofing: Article About Tile Roofing
Tile roofing, while more expensive than other types of roofing, can last up to 100 years and is very beautiful. It also requires minimal maintenance relative to other types of roofing. Clay tiles are more difficult to work with than asphalt shingles, and it is best installed by an experienced Sacramento roofing company.
A common misconception about tile roofing is that is should only be used in areas that are generally sunny such as the American Southwest. However, tile roofing can be used effectively in any climate.
The classic rounded clay tiles are called clay barrel tiles. Clay tile roofing is very heavy. Concrete tiles are a substitute for clay tiles that work almost as well and are less expensive. They are lighter than clay tiles, but do not last quite as long. Like clay tiles, they look great.
Copper nails should be used instead of galvanized nails when working with clay or concrete tiles. Since copper nails have more play than other types of nails, they will not crack if the roof decking shifts in changing weather conditions. Also, they can be cut out easily if the tiles ever need to be removed.

Furthermore, copper is the best material for flashing when working with clay or concrete tiles since it will last as long as the tiles themselves.
Because of the heavy weight of all clay tiles, roof decking must be at least 3/4 of an inch thick. If the roofing is not thick enough, additional plywood sheathing can be applied. It is not always necessary to use underlayment with clay tiles, but it is certainly a good idea. Tar paper, 30-pound felt, latex waterproofing or poured hot asphalt can be used.
Chalk lines are used to lay out exactly where clay tiles should go on a roof before they are fastened. This is important since a row of tiles can't end at the rake halfway through the tile. Clay tiles are first cemented where they overlap one another and then nailed down. Clay tiles hang out over the eaves for 2 inches.
Concrete tiles are attached to roof battens, or they are simply nailed directly to the sheathing. Some types also interlock with one another between courses. Using metal clips can provide more support in areas where there are high winds.
A metal drip edge should be installed on the rakes and also on the eaves with all types of tile roofing. Also, safety googles should always be worn when cutting any type of tile.
