Slate roofing has been used on buildings for more than a thousand years. This practice was brought to the New World by European settlers. Nothing else quite matched the durability, aesthetics, and fireproof qualities that were available with slate and this same quality remains today.
As one of the largest installers of slate roofing in the world, Durable Slate can handle any kind of slate roof on any kind of building. With the largest stock of reclaimed slate in the country, we can match most slate roofs whether performing a complete restoration, or installing a slate roof on an addition, or repairing large sections damaged by fire, wind, storm, and other forces of nature.
Reclaimed slate can also be used on a re-roof or new build should one desire a historic look without waiting years for it to age. Also, if the slate is in good condition, it is sometimes possible to re-roof using the same slate with new underlayment and flashings. The small percentage of slates that would be needed in the re-roof would be made up with matching reclaimed slate.
For installations with new slate, we prefer to install only the highest quality time-tested slates from the quarries of the Vermont Slate Valley, Virginia Buckingham, Southeastern Canada, Wales, and certain select European quarries. The combination of high quality slate, expert flashing design and installation, correct soldering, necessary underlayments for the conditions, and proper slate laying and fastening produces an aesthetic, long lasting roof that should have a serviceable life of 100+ years easily.
Cutting corners on any one of these factors can shorten the life span of a slate roof from 100+ years to literally just a few years or less. We have replaced numerous slate roofs that were less than 10 years old because one or more of these factors were lacking. Though quite beautiful, many imported slates are of such poor quality that they start rusting and falling apart within a few years of installation. Starting with a high quality slate is a must.
Even with a high quality slate, problems can arise when protrusions and transitions are not handled expertly as these are the areas that tend to leak the most. Common deficiencies found in slate roofs installed by novices include:
Allow our experts to explain how these and other factors are important for your particular project and don’t get fooled that all slate roofs are the same. A 100+ year slate roof comes into being only with the right materials, correct design, knowledge of the correct procedure to install these materials, and the skill to do it expertly.
I want to thank The Durable Slate Company for the fantastic job they did in replacing the roof on The Church of All Saints in Keokuk, Iowa. The workmanship was superior. Your work crew was very understanding to the tough schedule or working around a busy church. I know this was inconvenient for your crew and I deeply appreciate it. Whenever anyone asks, “Who did your roof?” I respond “The Durable Slate Company from Columbus, Ohio, and I can highly recommend them.
