"I was totally satisfied with the roofing project. I got 3 bids and this company's proposal was the most cost effective. It was also right in line with my cost expectations due to other roofing projects that I had done elsewhere. He also kept in touch with me as to timing as roofing shingles had some delivery issues due to the pandemic. Once he started, his crew was in and out in a single day with no disruptions to me. Upon inspection, it was a thorough job and I've very satisfied and will reach out to the company for other projects. I highly recommend Jalbert Contracting."

"I knew from the start I wanted a metal roof and that I wanted the Permalock product for its quality and durability, and that it looked like the shingle roof we had. The lifetime guarantee and product sold me. The roofers were great, and every night the place was cleaned up, very efficient company."

Roofing FAQs, answered by experts

The four types of roof sheathing are plywood, oriented strand board (OSB), planks, and tone-and-groove boards. The overwhelming majority of homes use the first two (especially OSB) and the other two are not often seen outside of special use cases. Methods of sheathing include solid sheathing, open sheathing where there are gaps, and plank sheathing. Most roofs are solid sheathing.

You can put a green roof on a regular house with a compatible slope. Green roofs are best suited for flat or gently sloped roofs, as steeply pitched roofs can make the installation and maintenance of the green roof challenging. Flat roofs can support the weight of the soil and plants and ensure effective drainage.

Hail is unlikely to damage a tar and gravel roof because the hailstones will hit the protective gravel rather than your delicate roof membrane. A tar and gravel roof is the most resilient flat roof option, which means it’s the best one for areas that see hail, fallen tree debris, and blown debris from intense winds.

A roof pitch that’s too shallow won’t shed runoff as quickly, so you have an increased risk of water intrusion through the seams between your roofing materials. In colder climates, snow and ice will accumulate more easily on your roof, which can add enough weight to cause roof collapse and structural damage to your home.

If your roof has storm damage, there will be some telltale signs. These include missing, loose, or damaged shingles. You may notice cracks or dents on the metal parts of your roof, like flashing, gutters, or metal panels. Water leaks are another big indicator. So are visible signs of impact. Rather than climb up on your roof to check, hire a professional to inspect the area  safely.
