"MHI exceeded expectations! Had a minor leak during strong winds, which indicated our original roof urgently required replacement. Recommended by a coworker, MHI proved exceptional. Transparent throughout, they provided ample visuals, expertly addressed queries, and detailed the roofing process, our roof's condition, available solutions, and financing options. Communication was seamless, accommodating calls or texts. They completed the roof and gazebo replacement in just one day. For comprehensive service, choose MHI. I wholeheartedly endorse them and am willing to share my positive experience with anyone interested."

"Everything went well, very impressed by how effective and professional the crew was . They were on our roof by 8am and pulling out our driveway at 2:30 . Couldn’t even tell they were here except that we had a brand new roof. Definitely would recommend them"

"Absolutely wonderful!!! Their assessments and recommendations were well documented and presented. The entire construction process was outstanding. They always have a LIVE person answering their phone and are incredibly responsive. We initially called regarding an ice-jam leak and they had a technician out within an hour at no charge! Remedial work on J-channel caulking was great. We asked for a complete assessment of our roof, leading to the complete installation."

Roofing FAQs, answered by experts

Shingle roofing can last anywhere from 15 to 50 years, depending on the type and quality of shingle, your local climate, and how well you maintain your roof. If you live in an area that sees extreme weather, like strong winds, hail storms, or hurricanes, the average life span of a shingle roof will often be on the shorter end, especially if you choose a more affordable roof shingle that isn’t designed to persist through extreme weather.

Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

Rain shouldn’t come in through your ridge vents unless your vents are damaged or the rain is accompanied by very high winds. Most ridge vents use flashing or baffling to keep out rain, snow, and debris. If your ridge vent isn’t baffled, rain is more likely to enter your attic, so ridge vents with baffles are a better choice in areas with regular rainfall.

To apply for a roofing permit, contact your local building authority. You may visit their office in person or contact them via phone or email. For more information on how to start the process, visit their website.

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.
