Slate is a metamorphic rock formed by superheated clay mixed with volcanic ash, making it a very durable and enduring part of residential and commercial structures, particularly of roofing systems. Many homes also use slate roofing due to its longevity wherein it can last a minimum of 50 years if well tended to. The key point here though, is well-tended to.
Even if the seller of your house or roofing contractor in the City of Charleston in South Carolina (whichever may be the case) told you that slate is “a hundred-year roof”, you shouldn’t interpret it to mean that a slate roof will last a century without maintenance. In fact, proper slate roof maintenance requires you to do an annual check for any sort of damage, and when needed, you’ll have to call up reliable Charleston roofers for replacement or repairs.
An article from Oldhouseweb.com emphasizes that you need to have your roofing inspected by professionals regularly. In many cases, reliable contractors like CMS Roofing can detect faulty repair or installation that you won’t readily see. Getting these hidden problems straightened out can help you avoid worse problems like your roof springing a leak that can eventually compromise the integrity of your home.
Speaking of leaks, did you know that your roof’s flashing or fasteners are more likely to fall prey to water damage way before your sturdy slate roof will? If you think that your roof’s flashing is already past its useful life and obviously showing signs of deterioration, have it replaced as soon as possible. You should also pay close attention to the condition of the steel, copper, or galvanized steel nails holding your slate roof in place.
After your trusted roofer in Charleston, SC completes his inspection, and he determines that about 20% to 30% of all the slates need replacement, it might be wise to have your entire roof replaced. Moreover, one of the telltale signs that your roof needs replacing is the presence of major flaking or delaminating.
Your roof protects the rest of your home from the harsh effects of the weather, and a slate roofing system can do this for a very long time. However, without the right amount of care and attention, you won’t be able to make the most of such a valuable investment.
