"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."

"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

A solar roof can replace an existing roof. Solar panels fit on top of traditional roofs. In contrast, solar roofs that contain photovoltaic (PV) materials, like solar shingles and solar tiles, are standalone roofing systems installed as a main roof. In some cases, installers can place them on existing roofs and as part of new construction. Carefully assess and choose the right type of solar roof replacement for your home and needs.

Most Cape Cod houses are two stories tall at the peak, although they’re considered one-and-a-half stories tall because the steep roof pitch cuts off a portion of the living space on the second story. Unless you raise the roof on your Cape Cod house to add a dormer, the interior rooms upstairs will lose some usable living space to the sloped ceilings.

Metal roofs last for between 50 and 70 years, and asphalt roofs last for between 20 and 25 years, with some lasting as long as 30 years. In most cases, you’ll get double the life or more out of a metal roof than you would from a shingle roof, which helps make the higher cost of a metal roof more manageable.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

There’s no single best roofing material for flat roofs, but EPDM is considered an excellent option because it lasts longer than TPO roofing and built-up roofing, and it’s the most adaptive to extreme temperatures and variations in temperature. EPDM can also be highly energy-efficient at both ends of the climate spectrum, with black EPDM helping to reduce heating bills and white EPDM helping to keep your building cool in extreme summer temperatures.
