Get matched with top roof sealant application pros in Manchester, MD

"I love this company! They always answer when I call and immediately schedule me - unlike other roofing companies who will either “call me back” (and never do) or just never answer their phone. I’ve used them twice - once to repair a siding issue and another time to replace my flat roof. The estimator (Rick) is always on time, professional, patient and nice. Both jobs I didn’t even have to be home for them to do the work. They took pictures of the work done and emailed them to me. This is my roofing company for life!"

"Lea did a wonderful job as a project manager for my roof install."

"Estimator came out with a drone to look at condition of the roof. Gave us 3 different options for roof replacement. We choose the middle price option. Big crew came out and did the work quickly and neatly. The price they quoted us was half of what other contractor wanted."

"We were very happy with the work from Pablo and Mario and JWHI — they were professional, punctual, and did great work on a variety of handyman chores, from painting, to caulking to fixing doors and patching up a leaky roof. When new issues arose, they proposed and executed creative solutions. Really happy with the work."

"This entire process has been smooth and absolutely fantastic. The roof looks great and the crew is amazing. Would absolutely hire again for future projects."

"I would definitely contact William Mackay Roofing again! I was told by a different contractor who fixed some gutters, that I needed to have someone who knew how to fix flat roofs inspect my flat porch roof. After asking around, several people highly recommended contacting William Mackay. Brittany quickly scheduled for a technician to come out -- and the same day Mr. Mackay inspected my roof and emailed me the proposal. He answered all my questions (as did Brittany!) The work was scheduled quickly - and the installers/technicians completed the work in one day. Everything was cleaned up (old roof pieces, etc) afterwards. I was a bit wary about having anything done to my home with COVID-19 -- but everyone really seemed aware of social distancing. I was very happy with how streamlined this went, and how pleasant it was to work with William Mackay Roofing."

"We have been looking for someone to take on our roofing and wall repair project for over a year and a half. Finding John is honestly one of the best things that's happened to us since moving into our home. It's hard to find someone who does high quality roofing and masonry repairs, uses high quality materials, is easy to communicate with. John checks all the boxes. A+ When I inquire for an estimate and service in a voice message, John reached out to me the very same day. He was extremely detail-oriented and picked up on all sorts of little things. He was professional and really knows what he is doing. There were at times I didn't what was needed for our roof but John was right there for us like our skylights needed flashing and one of the vents needed to be replaced. John cares about my home like it's his! He went out of his way to custom order shingles I liked. Once installed, we couldn't be more happy how well it looks for our home. Working along with John is his brother Dan who did a fantastic job in making sure our wall repairs were done right. A real solid person. Before leaving the finished wall repair job, Dan walked to every repair spot to see if everything is ok and even asked us if there is we wanted him to take a look at. A+ We are really grateful to have found John and look forward to working with him on future projects."

"A+ for ethics and professionalism. The repair on our old and non-standard roof was tricky and ultimately didn't last (roof leaked within 14 months). However, when the owner was contacted (he's busy so it took a while) he came out personally and arranged for an alternative fix to the roof. The owner, Dave Garner, did this at no charge, without being asked. We still don't know if we have a permanent solution but we're really impressed with Dave and the company's business practices. We would be pleased to use them for any future roofing repairs (although we hope we don't have any!)."
