"The repairs, the clean-up, and the pleasant experience exceeded my expectations. A large oak tree fell on our roof, breaking through roof rafters and ceiling joists with branches in the bedroom. It is an older house with loose fill insulation in the attic. As soon as the tree was removed, Steve's crew covered the gaping hole with a tarp and did the interior carpentry to replace the rafters and joists. They also cleaned up in the bedroom everyday so that I did not have to call a clean-up company The entire roof and chimney flashing was replaced. The estimate that was provided for the repair was not questioned by the insurance company, It was a pleasure to deal with Steve. He is pleasant, and always responsive to phone calls and emails. My first experience with Steve was at my daughter's newly purchased house to waterproof a stone chimney. Her "house inspector" said that the two color stone was because they came from different parts of the quarry. Steve correctly diagnosed that a new cap was needed and that water was seeping in from the top. Problem solved- the stone dried up in a couple of weeks and is now the same color on the whole chimney. I recommend Angus Theriault without reservation."

"Elite Work Home Improvement made the most difficult part of roof repair simple. My roof had been swamped by heavy rain and my soggy shingles needed a lot of work to remove the stains, and mold and provide an even texture for a smooth finish. They did a top-notch job. Their fast service and knowledgeable staff made the repairs worth all the money. It was stress-free to leave this task I hated to them. It's always a good idea to gather the opinions of experts and go through references of companies before you hire them. Elite roofing is the perfect choice for roof shingle repair."

"Arian repaired my old slate roof; replaced damaged slates, installed copper flashing along the ridge lines. Has not rained yet, but I trust he will stand behind his work. Price was fair. he arrived on schedule, and completed work in one day. Most importantly, Arian is more than a roofer; he is an artisan with a feel for slate."

"Jose was on time and professional. He inspected water leak problem on my roof, took pictures to show me the issue and gave me the options for repair. He came back later in the day and repaired the leak. I would definitely recommend Jose for any roofing issue."

"Its the weekend before Christmas and the roof is leaking. The local home improvement company said it would take 30 days for repair. I searched for roof shingles on google and pop this company. They got my roof fixed in a week. It's so fast that they guarantee it."

"They were the only local firm that knew I needed a permit for the roof to be replaced and how the process worked. (All of the other local firms told me that no permit was required.) The quality of work was decent (even though nail guns were used). The job was completed in one day (18.5 squares with a tear off and decking repair). The cost for the roof replacement project was double the national average. The only real issue that we ran into was in the cleanup phase. During the tear off phase, the crew dumped the old roofing materials onto tarps on the ground. Some of these materials missed the tarps and others were carried by the wind. When the crew said they were done with the job and left, they had not cleaned up the yard properly and swept the property for nails and staples. Management had the crew return to the property to do a proper cleanup within a few hours of learning of the issue. If you want a good quality roof replacement, I recommend them (as a former roofer). These people were clearly better than all of the others than I spoke with about this project and obtained bids from. (This firm definitely will not be the lowest bid and they will not be the highest either.)"

FAQs for natural slate roofing repair projects in Katonah, NY

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.
