"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."

"Brian and his team replaced several sections of my roof 3 years ago. They did a great job so when another section of my roof had some damaged shingles I called him to fix it. He called back promptly, and within a week the repair was done. Excellent service!"

"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."

"Since 2017 I have employed Atlas Roofing on four separate occasions. The projects they completed on our Cape home included roof repair, roof replacement, cedar sidewall shingle replacement and Azek trim board installation. Owner Paul Case always responds quickly to my inquiries, bids competitively, and completes the job promptly. It is readily apparent that Paul takes great pride in his work. His craftsmanship, knowledge base and attention to detail are second to none! I live out–of-state and can’t always be on site. I implicitly trust Paul Case to do the job right and he never disappoints. If that isn’t high praise, I don’t know what is!"

FAQs for natural slate roofing repair projects in Onset, 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.
