Slate roofing is steadily becoming one of the most popular roofing materials in the country. However, that doesn’t mean you should dive headfirst into having one installed. In fact, most roofers don’t actually have much experience when it comes to slate roofs – to the point that uninformed roofing professionals will recommend a slate roof be replaced when it actually doesn’t need to be. With that in mind, it’s best that you learn as much as you can about this roofing material.
Nails – When it comes to slate roofs, the nails that you should use during the installation should be made of copper, stainless steel or hot-dipped galvanized steel so they can last as long as the slate roof itself. The length of the nail is also important and should be double the thickness of the slate in order to penetrate the roof’s sheathing boards without punching through the other side.
Where It Comes From – While knowing the cost and color of the slate you’re putting on your roof is important, knowing where it comes from is something that you should know as well. This means you need to know the name and location of the quarry where it was dug up since some quarries have better reputations and warranties compared to others. As much as possible, look for a slate that is warranted to last 75 to 100 years.
Underlayment – According to roof repair experts, underlayment on slate roofs is a disputed subject. Some roofers tend to insist that an ice and water guard beneath the slate is needed, but this isn’t actually the case. In fact, when it comes to underlayment, you should stick with the traditional, 30-pound organic roofing felt to protect your home. You won’t have to worry about storms either as the slate itself will shed the water and protect your home.
Sheathing – Sheathing is the wood to where your slate will be attached and ideally lasts for 150 years. When it comes to this, the best material to use is individual plank boards of any material so long as they’re not plywood, particle board or laminated woods. This is because those three are made with glue and won’t last long enough to provide your home with a worthwhile protection.
Equipment and Technique – As much as possible your roofers have to choreograph the project so they won’t have to walk on the slate too much. Roofing contractors should use roof brackets as they work as well as slate cutters, hammers, hooks and rippers to make the job go as smoothly as possible.
Contract – When it comes to the paperwork, on the other hand, experts recommend that the contract be as detailed as possible. Most importantly, you should also ask your contractors to include a clause that says they’ll build the roof according to the installation guidelines of Slate Roofing Contractors Association of North America, Inc.
