RoofCo Reveals: Fixing an Incorrectly Repaired Slate Roof
Fixing an Incorrectly Repaired Slate Roof
Let’s face it, not just any roofer can repair a slate roof. There are those that will attempt to and in many cases, we are called to fix a failed repair. Not only can the failed repair cause further damage, it also leaves the homeowner paying twice for a repair that could have been successful the first go-around. It happens more often than you might imagine. Learn what you should do when considering roof repairs.
The Roofing Company rescued this slate roof after a failed repair.
Here is the RoofCo Reveal:
First, the wrong slate tile was used. It is obvious by the apparent dark colored slate shingles; they don’t belong there. Can you guess what type of slate was used for the repair? If you guessed Buckingham Slate, you are correct. Although a fantastic slate product, it is the wrong kind for this roof in Hilton Village The various shades on this roof should tell any experienced roofer that this is a Semi-Weathering Gray/Green Vermont Slate roof.
Second mistake was using a strap repair, which both looks bad and the straps are easily bent open by sliding ice and snow. The illustration is from The Slate Roof Bible (second edition) by Joseph Jenkins to show a close-up of the “Don’t do this” strap technique.
As you can see, the replacement Semi-Weathering Gray/Green Vermont Slate tile, which is the type of slate used in Hilton Village, Newport News, is a much better fit and will weather (change color) more evenly over time.
For this repair, we used a stainless steel black slate hook approved by National Slate Association and Slate Roofing Contractor Association.
