Roofing Repair
Specializing in asphalt and EPDM rubber roof repairs, we address flashings, valleys, skylights, and decking replacements. Our team ensures thorough diagnostics and permanent fixes, backed by a 10-year guarantee. By matching existing materials and avoiding temporary patch-ups, we extend roof longevity while maintaining aesthetic integrity.
Attic Ventilation
Proper attic ventilation prevents heat buildup and moisture damage, enhancing energy efficiency. We install intake and exhaust systems to regulate temperature, reduce ice dams, and extend shingle life. Our solutions meet manufacturer warranty requirements, ensuring long-term structural health and lower utility costs.
Blown Attic Insulation
Using PINK Fiberglass, we deliver fast, mess-free blown insulation for optimal R-values. Our process ensures even coverage to minimize settling and maintain energy savings. Timely installations (under 4 hours for 1,000 sq. ft.) and advanced equipment guarantee efficient thermal regulation and reduced heating bills.
Chimney Repair
We handle chimney flashing, liner replacements, and masonry repairs with precision. Free inspections identify structural risks, while durable materials ensure safety and compliance. Our 10-year guarantee covers safe removal of damaged components and restoration to prevent water intrusion or fire hazards.
Gutter Guards
Our stainless steel mesh gutter guards prevent debris buildup, avoiding clogs and water damage. Customizable for varying roof pitches and foliage, they come with a 12", 18", or 24" mesh design. Seamless integration with existing systems ensures low-maintenance, durable protection against foundation erosion and basement flooding.

Report
I contacted Kevin to do a number of repairs to both the rubber roof and shingled areas of my roof. He was prompt in doing the inspection, identified areas of concern and very clear in explains the issues. The work was done sooner than I expected and was done very well. I recommend his company and will use them for any future work needed.

I can't thank Kevin enough for his work in August. I called early one morning after days of off-agin, on-again heavy rains, because our kitchen vent hood was leaking. Kevin stopped by that day, saying he was going to be in the area. He made a quick diagnosis and did what he could to remedy the situation on the spot, he offered potential next steps and alternatives, in case that wasn't enough. We haven't had a problem since!!! (I had called several contractors who wouldn't even put me on their schedule -- they said they were too busy for repairs this year.) You should call Kevin!!

Report
Kevin's crew started work on my roof with the plan of tearing off and replacing shingles and doing some upgrades to the ventilation; they worked from one problematic area to another, most of which were unexpected. Every issue was addressed and corrected. They fixed and replaced not only the roof but the soffits and fascia where there were multiple areas of rotted wood. Everything was done professionally. Kevin and his crew were easy to work with and pleasant. I couldn't be more grateful!

Found Kevin Sterwald through Google. Decided to give a call, what a great choice we made! His crew worked hard and took off old shingles, and installed a new Roof. They did a beautiful job, and kept the yard clean. We never found a single nail. Our new roof is beautiful! We are so impressed!

This company was a joy to work with! We contacted them with what we were looking to have done (wood burning stove chimney pipe removal) and they contacted us back in a timely manner. The quote given was very reasonable and accurate after the work was completed. They were able to come out and do the work within a week, compared to other companies that quoted multiple weeks out! Everyone we worked with was friendly and the job was done extremely well! Would recommend to anyone!
