What Does Roof Slating Mean In Construction?
Roof slating is the process of installing roofing slates, which are stone slabs made out of slate, on a roof.
Slates are suitable for roofs with a pitch of more than 20 degrees and are laid to the same double lap principles as plain tiles.
The size of the slate determines the minimum roof pitch required and the amount of head lap needed.
Roof slating also involves installing an appropriate underlayment on the roof deck prior to laying the slate shingle, as well as using nails that have an anticipated service life at least equal to that of the slate.
Slate roofs can last up to 100 years and offer numerous benefits such as being water-, fire-, fungi-, temperature-, weather- and mold-resistant.
What Materials Are Used For Roof Slating?
Slate roofing is a premium roofing material made primarily out of natural slate tiles and other slate roofing materials.
It is one of the most durable and longest-lasting roofing materials on the market, but it is also one of the most expensive types of roofing materials.
Slate roofs are installed one tile at a time, and they require experienced installers to ensure a consistent look and quality across the entire roof.
Slate shingle roofing is sourced from quarries in New York, Pennsylvania, Vermont, and Virginia, with some quarriers selling directly while others sell through distributors. Popular brands include Vermont Slate Company and Natural Slate.
Synthetic slate roofing is an eco-friendlier alternative to natural slate that creates the look of slate without its weight, cost, or installation difficulties. It is made from up to 80% old tires and other post-consumer rubber products.
Why Is Slate Used In Roofing?
Slate is a natural, sedimentary rock that has been used for centuries as roofing material. It is highly durable and resistant to weathering, making it an ideal choice for roofing.
Slate roofs are also fire-resistant and mold-resistant, and have a low water absorption rate of less than 0.4%, making them waterproof.
Slate roofs are also aesthetically pleasing, coming in various colors such as grey, green, purple, black, red, and multicolored. This makes them attractive to homeowners looking to increase the resale value of their home.
Slate roofs are also relatively low maintenance due to their superior durability and longevity, however they can be expensive to install and maintain due to their weight.
Additionally, slate poses a safety risk when external companies need access to the roof for work such as cable installation or power washing.
What Are The Advantages Of Slate Roofing?
Slate roofing offers many advantages to homeowners, including its long lifespan of over a century, its attractive appearance, its fire resistance, and its low maintenance requirements.
Additionally, slate is mold-resistant and has a low water absorption capacity, making it highly resistant to weather events such as strong winds.
Slate roofing also boosts the value of a home, making it an attractive option for potential buyers.
The main disadvantage of slate roofing is its cost. Slate tiles are heavier than other roofing materials and require more labor to install, resulting in higher installation costs than other materials such as shingles.
However, the long lifespan of slate roofs makes them a worthwhile investment in the long run.
How Long Do Roof Slates Last?
Slate roofing tiles have a long lifespan, typically lasting between 50 and 100 years. The exact lifespan of a slate roof depends on the origin and quality of the slate, as well as other factors such as weather conditions and maintenance.
Hard slate can last up to 200 years, while soft slate will last only 50 to 125 years.
Additionally, the weight of the material can be a challenge for installation, requiring wood or steel support beams.
