When should I replace my slate roof?

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

What is the expected lifespan of a slate roof?

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Can I perform temporary slate roof repairs?

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.

Roberts Roofing Company, is a family owned business serving the Pittsburgh metropolitan area since 1948. We provide quality work at an affordable price. We are the number 1 choice for all of your roofing needs. Give us a call today and see why we are the best in the area!

"Anyone with a slate or tile roof needing repairs should consider using Roberts Roofing. A tree crashed through my 70 year old slate roof. There was damage to half the front side of the house roof. The roof is very different from most slate roofs. While most slate roofs use the same color, width and thickness tile, my roof used random width, color and thickness tile. Matching their work to the old roof was a challenging job. The Roberts team ( 11 craftsmen ) removed slightly more than half the roof. They mixed in approximately 2,000 reclaimed tiles from their vast inventory with the tiles they harvested from my roof. The result.... excellent. The pattern match.... flawless. The craftsmanship.... top quality. The execution time.... phenomenal. Thank you Josh, Samuel and JW."

Bachman’s Roofing is a family-owned-and-operated roofing company and has been for more than 50 years. Our skilled staff, from our knowledgeable customer service specialists to our expert roofers and remodelers, handle each project with precision and care. We provide each customer with excellent customer service, exceptional products and expert installation. Professional service with family values is what we guarantee.

"BUYERS BEWARE! We were excited to sign the contract and really felt that this was the correct choice for a rental we own after reviewing feedback on Google, HOWEVER, we were so WRONG. Salesman assured us that was no difference between paying cash, credit card, money order, etc. To our surprise, credit cards ARE charged an additional 3 percent surcharge. This would have been nice to know after spending over 37,000.00 for a roof. Their response was, well we have no control over what the salesman tells you and there is absolutely nothing they can do about the surcharge. So as the roof was being installed we were told by the supervisor on duty that all the debris would be cleaned up upon completion but that did not happen. In fact our tenants sent us pictures of handfuls of nails, staples and debris that was scattered all over the gravel parking lot that surrounds the front and side of house. Called Bachman's the following day and they sent out a project manager to view the debris, but WE were REQUIRED to be there when he arrived. The project supervisor cleaned up some of the nails, but not all since he only had a tiny magnet and this is a huge parking area. He said the crew that installed the roof is from Trenton, NJ and he would need to send them out in the next few days to clean things up. He said that they use "hundreds of nails when installing a roof and if a hundred drop to the parking area, well that's pretty good", WOW! We were also told by the project supervisor that he was INSTRUCTED NOT TO LEAVE until he had a check in hand for full payment, even though the property is surrounded by debris, nails and staples. We did not have our checkbook on us at the time so he followed us home and waited outside our house until the check was handed to him. After giving him the "post dated" check, we told him to wait three days for the money to transfer to the checking account otherwise our account would be overdrawn WHICH HE AGREED TO. Needless to say, he cashed the check the VERY SAME DAY that it was handed to him, OUCH VERY UNPROFESSIONAL, now we are facing over withdrawal banking fees. The only thing this company cares about is the money (and they need it IMMEDIATELY) even though you are not happy that your property is surrounded by staples, nails and roofing debris. The picture below was collected from only a 3' X 3' area. We are current owners of a family-run business for years and have NEVER and will NEVER treat a customer in this manner. Please take our advise and STAY AWAY. Bachman's is way over-priced and we should have chosen one of the 5 other roofing competitors who were at least 13,000.00 less than Bachman's. LESSON LEARNED THE HARD WAY."
