Sturctural Support For A Clay Roof

That means that the framing of your roof supports must be sturdy enough to carry all that extra weight.

Sturctural support for a clay roof.

This is not a diy project. A house frame constructed with lightweight prefabricated roof trusses is generally not intended to support the loads imposed by a clay tile roof. Clay tile roof battens are nailed at minimum 24 inches on center with spaces for drainage every 48 inches. Nevertheless even with heavier tiles most homes will require only minimal reinforcement.

Your roof structure must be able to handle the weight of a tile roof which may be as much as 850 pounds per square for clay tile and 950 pounds per square for concrete tile. Battens for use on clay tile roofs should be made from pressure treated lumber except in very dry climates. Clay tile roofing is commonly applied to steeper pitches. Clay tiles are typically selected only for roofs that have a pitch greater than 4 inches.

This means that most roofs and long as they don t suffer from maintenance issues can support lightweight concrete or clay roofing without modification or added support. These objects are made from commonly occurring natural materials which are mixed with water formed into the desired shape and fired in a kiln in order to give the clay mixture a permanent bond. Typical structural clay products are building brick paving brick terra cotta facing tile roofing tile and drainage pipe. Roof frame support reinforcement requirements since tile is a heavy roofing material concrete is lighter than clay 600 to 1 200 pounds per square as opposed to 1 000 to 1 500 pounds per square the structural support of the building must be taken into account.

Lay out battens to provide equal courses with a minimum 3 inch head lap unless the tile profile is designed for a specific head lap. The clay tiles you are using weigh about 8 pounds per square foot adding 5 pounds to the design dead load. Still it is important to seek the advice of a structural engineer for certainty.
