Gahanna Roofing: Article About Signs A Slate Roof Needs Repair
Slate shingles are one of the most durable types of roofing because they typically last between 75 and 200 years with proper maintenance. Unfortunately, many homeowners believe that slate roofs do not need any maintenance once they are installed. Like any other roofing material, slate roofs can start to leak and the shingles can crack, chip and slip out of place. This is why Gahanna roofing homeowners with slate shingles should get their roofs inspected at least once a year.
If the slate roof has been on the house for more than a few years, chances are it needs to be inspected and repaired. While the slate shingles can last for centuries, the flashing and nails do not. Flashing is used to create watertight seals around chimneys, vents and other external structures on the roof. It is typically made out of copper, galvanized steel or sheet iron, and over time, it can rust, resulting in a loss of water tightness and leaks.
Slate tiles are often installed with zinc, copper or steel nails. While these nails hold up well, they tend to rust out of the shingles long before the end of the shingle's useful life. This leaves a hole in the shingle where water can penetrate the roof and eventually the home, and the loss of the nail can lead to the slate shingle slipping out of place, which creates an even larger space where water can penetrate the roof.

Additional signs that a slate roof needs to be repaired include broken, cracked or chipped shingles. This type of damage will often appear as discoloration and roughness along the surface of the roof.
Signs of a water leak include an increase of mold and mildew in the home, especially in the bathrooms, and water spots on the ceiling. The best time to check for water leaks is during or right after a rainstorm. The homeowner should climb into the attic with a flashlight and look at the roofing beams for water.
It is important to note that slate roofs should never be repaired with roofing tar. Sealants and tar are unsightly on slate roofs and can lead to more problems, including the need to replace the entire roof. This is because roofing sealants only cover up damage, which means the roof cannot be properly inspected or repaired. Instead, homeowners should look for roofing contractors that are willing to inspect and repair damaged shingles and flashing and install new nails to secure the shingles.
