Royal Roofing Inc., provides its clients with the following types of slate roofing: Welsh, Chinese, Spanish and Brazilian. True slate shingles are produced from metamorphic rock and are extremely tough. Nevertheless, it is possible to split them into thin layers that comprise individual slates. Usually, true slate shingles are uneven and of irregular sizes. Welsh ones are an exception, as they have a smooth surface and are of regular sizes. They became popular as railroads entered the network of global transportation systems.

Slate Roof Installation

While installing a slate roof the technician should use a brick bond pattern. In other words, the joints between each one should be adjusted with the center of the above and below slates. This leaves space between the sides of about 3mm allowing double covering since the top part of each slate is covering the center of the one in the next row and the lower part of the one located above.

The amount of overlap is dictated by the roof slope. The steeper it is the less overlap is required. Shorter roof slates are used in the composition of the lowest row of roofing near the fascia board to provide the double overlap for the first row of full-sized slates. As such the lower edges of these short ones should coincide with the first row of the full ones. The top row at the ridge of the roof is composed of half slates for the same purpose. The top edge of the first row down must be covered with a ridge tile. Instead of galvanized nails aluminum ones should be used since aluminum does not corrode. Hence copper and stainless steel nails are acceptable. They can be nailed either at the top or the center. In case the nail is at the top it is covered by two slates limiting disclosure. yet since only one end is secured more risk of breakage and wind uplift arises. Alternatively, when the nail is deposited at the centerline of the slate the protection to the nail is decreased. Nevertheless, it should be noted that the risk of slates being lifted by strong winds is diminished. In general, the ultimate way to compensate for added exposure is to nail the slates right at their center.
