Killeen Roofing: Article About Clay Tile Roofs
In areas of the United States that have a moderate to hot climate, clay tile roofs are popular. Not only is this roofing style aesthetically appealing, but it also offers an increased level of resistance against the sun's intense heat. The installation process for clay tiles is different from that of asphalt shingles. When a homeowner is considering the installation of a clay roof, Killeen roofing contractors can determine whether any structural changes will be needed and whether or not the house will be a good candidate for this type of roofing system.
The first step in the installation of a clay roof is determining whether or not the wooden trusses, joists and beams can handle the increased weight of tiles compared to asphalt shingles. If the home is in the construction process, this is an easier assessment than if it is an existing residence getting a replacement roof. In some cases, a structural engineer may need to evaluate the building's strength before the clay tiles are placed.
Next, a roofing underlay will be applied to the roof decking. This underlay helps to protect against moisture infiltration. The decking will need two layers of underlay.

Proper installation of the underlayment is essential for the performance and durability of the new roof.
Installing metal flashing around any roofing protrusions is the next step in installing a clay tile roof. The flashing is needed to protect openings around chimneys, vents, conduits, pipe flues, skylights and other openings that go through the roof's wooden substructure.
Once all the flashing is in place, the roofing crew will start laying the tiles. The first tile is centered and positioned on the batten and secured with a 10d nail. This initial tile must overhang the batten by a minimum of 2 inches. The next clay tile will be installed at the inner end of the first one, with a slight overlap between them. This process will continue all the way up to the roof's ridge line and all the way across to the intersection of two roofing planes if the roof is cross gabled.
In some clay roofing systems, mortar is used. This material must be mixed to a medium consistency. The mortar is applied to the outer edge of the tiles to form a barrier against animals such as birds, rodents and insects that might try to set up housekeeping in the rooftop. The mortar also helps to protect from water or moisture seeping underneath the tiles.
