The Durable Way

Our Unique Approach to Roof Repairs & Installations

Proper Assessment

Our Assessment, action planning, and implementation strategies are unique to historic roof repair. Many of the “basic principles” and diagnostic techniques used by generic, modern day roofers do not apply to historic roofing. Slate, tile, and copper roofing each have different properties as compared to asphalt roofing, requiring different approaches. We’ve worked on countless old roofs, some dating back 300 years or more, and have learned how to best respect those differences. With such breadth of experience, we know what works and what doesn’t for every kind of roof and any kind of roofing or copper gutter problem. Our senior technical expert, John Chan, serves on the board of the National Slate Association, and is one of the leading experts in slate and clay tile roofing in the country.

Appropriate Materials

Many clay tiles made 50 – 100 years ago are no longer manufactured and the only way to match them is with reclaimed tile. Complicating matters further, many types of slate that were used on older buildings are still quarried but have weathered to a shade that can be vastly different than the freshly quarried. With one of the largest stocks of re-claimed slate and tile in the country, we can provide matching pieces for most slate or tile restorations, making for a seamless slate roof repair or clay-tile replacement.

Choosing new materials is equally as important. Factors such as weathering, the quality of the clay or stone at the time of quarrying, cleaving and cutting, etc, help determine the lasting durability of your new slate roof or repair. For new roof installations, we use only materials and suppliers with proven track records so your historic roof continues to stand the test of time.

Skilled Artisans

durable slate company, About Us

Our artisans have been honed to keen edge through training and real-world application. Generations of accumulated experience from expert slaters, not to forget thousands of completed roofing and renovation projects of all kinds, provide our craftsmen with the extensive practice and knowledge necessary to complete any historic roofing project.

Sadly, inexperienced slate and clay-tile roofers produce an inferior product. This means trouble down the line, like leaky chimneys, falling slate tiles, cracks, discoloration, and other disattisfying or dangerous problems. The work of a skilled artisan can last a hundred years. Why dishonor your historic roof with anything less than the best?

The Durable Slate Company is frequently recognized for our exceptional work restoring historic slate, clay tile, and metal roofs and other historic structures. Our artisans stand among the best world-wide.

Quality Control

This high standard of integrity in the company has lead to multiple awards for ethics and integrity including the International Award for Marketplace Ethics from the Better Business Bureau. 2019 North American Properties Award for Our Lady of Peace Chapel, on Xavier University, and frequent Super Service award’s from Angie’s List, given to the top 5% of companies who sustain a superior service rating each year.
