"Very good job. Extremely well done siding project with an experienced and thorough crew. The job was done despite there being a snow storm in the middle of it. Everyone was prompt to let me know what was going on. At the end of the project my project manager Taylor did a very detail-oriented walk-through. I couldnt have had a better experience. Loved every minute of it and the results definitely show."

"Signed a contract to replace half the roof for $5000 after assurance of no hidden cost and nominal cost for replacing some plywood. Due to rough weather the job was performed 3 weeks after signing. The roofer did not cover the roof with tarp and also spoke to Allstate who denied all my claims for damages. I was billed $1600 in addition to $5000. I have paid the $5000 but I deem the extra billing excessive. I was not informed of the cost for approval. I am willing to come to terms with the contractor and would like Angie’s list to review and work out a compromise. It also points to the level of service offered by the two contractors referred by your company. One bid for $2500 and precision roofing came in at $5000. I signed with Precision because of their assurances as an established company with a fixed cost. It has turned out not to be the case."

"Follow up to earlier review -JJP Contracting Jose and Brian are running a top tier business. I'm going to be totally honest with the people of Angi- We hired this team to perform a siding job and it originally didn't go well. They pulled down the pre-existing wood shingle siding that was rotted and installed new Siding on the home. When the siding first went up there was a defect that we all couldn't understand. We thought that it wasn't okay to leave it up but tried to see if the warmer weather would cause it to unbuckle. JJP stood by their words even months after the siding had been installed and came back to make the necessary fixes. I appreciate this more than the team knows because too often contractors are not true to what they say. This team is running an honest business that I can truthfully say that I trust. I look forward to discussing further projects with their group."

"I couldn’t be more impressed with Strong Hammer Contracting! From the moment I contacted them, their team was professional, prompt, and clearly experienced. They arrived right on schedule and handled my gutter cleaning with meticulous care—thoroughly clearing out debris and even checking for minor issues I wouldn't have noticed myself. What really stood out was their attention to detail and respect for my property—they left everything spotless, and my gutters have never flowed better. It’s such a relief knowing I can count on a company that takes real pride in their work. I’ll definitely be using their services again and recommending them to everyone I know!"

FAQs for roof sealant application projects in Katonah, NY

A roof coating system lasts between 10 and 20 years. With a premium coating and regular maintenance—like inspections and touch-ups—your roof will stay protected against weather damage and water intrusion. This enhances its durability and preserves its structural integrity throughout its lifespan. Make sure to keep in contact with a roof coating pro so that you don’t miss regulating resealing. 

You should recoat or reseal your roof every four to six years. Maintaining a consistent recoating schedule preserves the integrity of the protective seal and prevents moisture penetration and material degradation. High-quality, built-up roof systems require this interval, and if an EPDM roof begins to leak, replacing the coating becomes necessary to restore full protection.

A roof coating can seal small cracks and stop minor water infiltration, helping to prevent roof leaks. While the coating enhances the roof’s durability and prevents early signs of leakage, it does not replace the need for full-scale repairs when substantial structural damage exists. Professional evaluation and repair are required to resolve significant water intrusion and ensure your roof retains long-lasting protection.
