Roofing contractors offers various services for any types of projects. Roofers faces varying challenges of roofing installation projects which requires a particular skill-set for every type of roofing materials. But at the end of the day roofing materials such as wood shingles, asphalt shingles, slate, metal and clay roofing tiles are installed with similar fashion and characteristics such as waterproofing and flashing, but roof tiles needs special installation techniques to be more effective in keeping your house protected all year long. For a traditional roof appeal and long lasting overall roof protection, roof tiles or slate is the best option.
Building rigid base layer is very important for efficient structural support for the heavy roof tiles. Unlike other roofing materials, roof or slate tiles requires heavy duty base to compensate with its weight. The most commonly used base layer is ¾-inch exterior grade plywood. It is nailed down onto the trusses which forms a superior structural support layer for the much heavier roof tiles. While some installs a much thinner plywood for asphalt roof shingles, clay roof tiles requires a much stable base due to its weight.
Most clay roof tiles requires an exact type of underlayment required by the manufacturer, it is highly recommended that this process matches the manufacturer’s specifications for proper installation. It starts with a layer of simple tar paper stapled onto the top of the plywood in a waterfall format, with each layer overlapping the lower layer. Other roofers layer latex waterproofing or hot asphalt painted on top of the plywood. It would be better to follow the manufacturer’s instructions rather than doing a different waterproofing technique on your roof.
There are certain type of clay roof tiles such as s-shape, u-shape, and flat clay tiles; and all requires flashing. The most common type of roof flashing for clay roof tiles is L-shaped metal stripping that is installed on all the exterior edges, under the waterproofing layer and then screwed or nailed in place. Depending on the brand and style of clay tiles it may require other types of flashing, such as rubber or silicone based flashing. Also it is highly recommended that you follow the manufacturer’s instructions.
The fastening method of shingles onto the roof depends on the manufacturer. The traditional way of installing shingles on to the roof is to stack and overlap the pieces on top of each other into a waterfall format by using a concrete mortar to them in place. To today’s standards modern versions also include metal fasteners and horizontal battens. These new roofing components are designed to replace mortar, and are engineered to mount special screws that have a rubber seal to prevent water from penetrating the inner layer.
