"The service and work that Beantown provided was outstanding! From the very prompt and efficient estimate by Jim to the completion of the work from the workers everything was outstanding. Derick the project manager and his team with Tony, and others were here early on the day the work started and worked extremely hard the entire time they were here. When they left, the room was all cleaned up and it was like they were never here, except for the outstanding job on the installation of new skylights! They did a tremendous job, and they removed the old skylights that were leaking and installed the correct skylights for the pitch of our roof. We are extremely pleased with how the work was performed and how nice they now look. Previously the trim on the inside was all damaged from the leaking and continued to leak and show water stains. They repaired the trim also and now it looks fabulous and does not leak at all! It doesn't even look as if there is glass in the skylights as they are so clean and installed correctly! What an outstanding job Beantown did in a very timely and efficient time frame. The job was completed within 3 hours! We have already gotten an additional estimate for our main bathroom shower and will definately be proceeding with more work from Beantown. These guys and this company are top notch contractors and so easy and professional to deal with (and reasonably priced too)!"

"On Top Roofing is Top of the Line Roofer. Professional delivery with solid quality! Company was hired to correct the issues caused by a prior roofer whose incompetence has cost me additional thousands in repair. On Top Roofing installed a ridge vent that the prior roofer only placed on the roof, re-flashed the chimney where prior roofer failed to install to match new rook lines, re-surface flat rook where prior roofer ignored. In addition, On Top Roofing was used on apartment buildings to help close up the roof and eliminate a bat problem. On the Top Roofing is the only roofing company to use. It takes a while to get on their schedule, but they show when they say the will and do the job they say they will do. Only hire On the Top!! You will not regret."

"The roof was patched and I no longer have a leakage problem, I provided the wrong Shingles which were used unfortunately, and as a result the finished look is relatively poor, The company was very responsive and if they had the correct materials I'm sure the job would have been more than satisfactory. I need to remember it was a patch not a new roof. Try them, they came out between rain storms and fixed my leak."

"My wife and I had storm damage to our roof, skylight, and front shutters. I contacted several roofers to discuss the repairs and had few people actually call me back. When I contacted Cedar Valley Exteriors, I spoke to David Faraone pretty quickly and he was incredibly helpful and was able to walk me through the entire process to get my roof replaced and all the repairs completed and covered by my homeowners insurance. Very helpful."

"I recently had my roof repairs done in by Overstate, and I?m pleasantly happy with how everything turned out. I was a little overwhelmed and nervous going into this, but Avi and his team made the process smooth and stress-free. from the free quote to the repairs, it was a really positive experience, and I would absolutely use them again and recommend them to everyone."

"I had a jug of the recommended product, which Mr. Dexter used to spray the entire roof--not just the bad sections. He expertly corrected a downspout position to direct rain into main gutter. Two gutter covers were replaced with white-painted, seasoned wood, which were cut to the proper shapes. A deck board was fastened securely. Mr. Dexter plans to return to inspect his roof work. If additional roof treatment is needed, there will be no additional cost for me. [I had contacted 2 other roofing companies, which were recommended by Angie's List. One company did not respond. A 2d company gave a $930 estimate, which did NOT include spraying the roof for moss/algae.]"

"I cannot speak highly enough of Tom and Brad Green of Colonial Restorations. We have lived in our antique house for 16 years now, and like most old homes, some of its previous repairs were good, some not so good. Tom Green worked on this house for its previous owners, and his work was, by far, the best in the house. So, we continued to use Colonial - Tom, then Tom and Brad - as we learned the ropes about caring for an old house - our first house, old or new. Over the years, they have replaced sills and posts and beams, and rebuilt parts of our loose stone foundation. Most recently, they replaced the last original posts in our basement, (one of which was a tree trunk still with bark on it), including pouring new custom footings, in advance of our finally cementing the dirt floor. The work here is never easy - nothing is level, nothing is square - but the Greens' end result has always been beautiful - strong and made to last. Their prices are fair and without hidden costs....maybe not the lowest bid you might get, but you know it's a real bid that they will stand behind. They triage projects for us, giving us an idea of what other items will likely need attention in the next few years. We're not done with this house yet....we've never won the lottery, and there's always another repair..... and plan to use them again soon. I feel confident knowing that the next owners of this house, whoever they might be, will see the quality of the work and know that we cared enough to have the right people help us with the ongoing repair and maintenance of a 275+ year old house. I am a real person, a real customer, with no ties to the company, and was more than happy to write this review."

FAQs for natural slate roofing repair projects in Blackstone, MA

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.

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.

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.
