"We couldn't be happier with Dave's overhaul of our fireplace. His attention to detail, and commitment to excellence. We feel so lucky to have found him after another contractor flaked out on us. He came to the rescue & did whatever it took to get the job done on time and on budget. He is highly skilled and capable. Several times during the job he suggested things that would enhance the finished product. In doing so he created more work for himself. These upgrades probably added a full day of additional work. He didn't change the cost for the job, he just wants his customers to be happy. His attention to detail and cleanliness blew our minds. He spent a full day getting the room taped off to prevent dust from spreading throughout the house. A full day!?!? And it paid off when the work was done...we're not even hiring a cleaner. More than anything Dave's got a good heart, my wife and I genuinely enjoyed meeting and working with him. (Note: no AI was used in writing this review!)"

Welcome to Ranch Roofing! Our goal is to provide our customers with the highest level of service and satisfaction. Please contact owner Bob O'Sullivan today for friendly, personalized and award winning service. 12 Months no interest, no payment, same as cash (ask for details).

"We are writing to express our sincere gratitude for the outstanding service we recently received. Ranch Roofing installed our roof back in 2012. Fast forward to 2025, when we had damage to our ridge vent, we called Ranch Roofing, and within 10 minutes had a call back from the owner, Bob. He said he would have it looked at and fixed, but to our surprise, in a matter of a few days, he sent his crew, who ripped the entire ridge vent off and replaced it free of charge. We cannot say enough positive things about Bob, his Crew, and this Company. Thank you Bob- Your quick response and generosity are much appreciated! Sincerely, Maryann and Randy D. "

"I made an appointment with Amar to check out the leak I had in my roof. He arrived 10 minutes early, which was good, and checked my attic to see the source of the leak. He wasn't able to see anything obvious, so we made an appointment to stop by Sunday morning to check out the roof. Upon inspecting the roof, there was obvious damage from possibly large tree branches gouging a couple shingles. He was able to replace the damaged shingles at a reasonable price. I would definitely wire Amar again for any roof services in the future. "

We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"Review of Rain and Shine Masonry (Owner: Sean Boyne): After Sean waterproofed my foundation and installed a French drain, both failed within weeks, moisture and mold worsened, and a previously dry wall began leaking, leaving me with severe mold and massive repair costs. Despite a contractual 20-year warranty, Sean ignored all my messages and even a police inquiry. His listed ?home and business addresses? are only mailboxes, seemingly to avoid accountability. The project also involved a roof replacement that ended up costing nearly triple a typical price. Midway through, he said my roof plywood was below code, and that I needed major attic reconstruction, including rebuilding all of the roof valleys. The reconstruction turned out to be quite limited. I believe he overcharged by tens of thousands. He first underquoted, then added thousands once work began on the foundation project. Sean is in breach of contract and warranty."

FAQs for natural slate roofing repair projects in Waltham, 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.
