"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

You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.

The best material for your shed roof depends on your budget and personal preferences. For instance, if you’re looking for the most cost-effective option, rolled roofing is your best bet. Just be aware that it only lasts for five to eight years. If you prefer something with a longer life span (and you’re willing to pay for that durability), consider slate shingles, which can last for hundreds of years.

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.

Just like when you’re shingling a roof, you can install felt underlayment under a metal roof, but a synthetic underlayment like adhered ice and water shield is the best option. These use adhesives rather than mechanical fasteners, so you have fewer penetrations going through your roof deck and a lower risk of leaks. Ice and water shield is also easier to install because you don’t need additional tools or fasteners to attach it to the roof deck.

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.
