Slate is one of the most durable and long-lasting roofing materials you can find. With proper care, a slate roof can last over 100 years, meaning you’ll never need to worry about roof replacement again. Today, Vertex Roofing Contractors Inc. discusses a few things that you should keep in mind before going ahead with a slate roof installation project.
The most appropriate type of underlayment for slate roofing is the traditional, 30-pound organic roofing felt. Its main function is to protect your home in case there is a storm prior to the installation of slate. It’s important to note that slate itself is capable of shedding water and protecting your home. So an underlayment such as an ice and water guard is usually unnecessary for slate roofing.
Sheathing, or decking, is the wood attached to the slate. On average, it can last for 150 years, provided that the right type of material is used. Plywood, particle wood and laminated wood aren’t recommended since they are made with glue.
If you want to avoid roof repair, you should pay special attention to the nails that are used in the installation. Do not use electro-galvanized nails because they can become rusty in just a couple of years. Your best options are copper, stainless steel or hot-dipped galvanized steel nails.
Sidelap and Headlap
Slate tiles should have at least a three-inch overlap on the sides, called sidelap. Each slate tile should also have an overlap at its top, called headlap. For steep roofs, three inches of headlap are required.
