Widely considered as being one of the few and true “lifetime roofs,” slate is a premium roofing material that is more durable than asphalt shingles and tiles. Many famous buildings, in fact, use this material because of its top-notch strength and long service life.
Read on as Achten’s Quality Roofing, your local roofing and gutter contractor, shares a few things you need to know about installing a slate roof.
Various Installation Patterns
Slate roofs are often characterized as having uniformly-arranged gray or black rectangles on sloped roofs. However, that is not always the case. The material can be installed in many ways, and it depends on the size, color and texture of the material. For instance, a roof can have slate pieces of the same height and thickness but that vary in width. Another example involves contractors using different colors of the same material, adding texture to an otherwise uniform-looking roof.
Regardless of whether the roof has a skylight or not, the pros must make sure to reduce the chances of walking on the slate roof. The more they do so, the more likely the material will crack. For this, roofers use roof brackets, also known as “roof jacks,” which act like mini scaffolds.
Importance of Nails for Slate Roofs
Slate may be durable, but like other roofing materials, it needs to be nailed to keep them secured. Installers use copper, stainless steel or hot-dipped galvanized steel nails, making sure they are of the right length. Ideally, they must be double the slate’s thickness plus an inch. Once hammered, they will penetrate the roof sheathing boards but not all the way through.
