Customers say: Terrific value

"Freeman and Sons recently replaced my old metal roof with a new shingle roof and they did a great job! Brad was easy to work with from start to finish, always quick to answer my questions and keep me informed of any changes such as a delay due to weather. I went to work in the morning with an old roof and came home to a new roof-everything done in one day including the clean up. I definitely recommend Freeman and Sons!"

"While we hired AllAmerican construction to deal with a gutter issue, which they accomplished by adding a downspout and sealing an end cap, the reason we are giving them 5 stars is that they did a free inspection of of the roof and all things protruding from it. They took pictures of problems they found including openings around 2 standpipes and flashing problems around the chimney. Two days after that first meeting they returned with all the parts and equipment necessary to do the gutter work, replace the standpipes where they exit the roof, and do the flashing replacement/repairs. They also took further pictures of the chimney showing us areas where water has gotten into the chimney structure. We are currently in talks with them about taking the chimney down to the roof line and rebuilding it to fix these problems. We have been very pleased with all three people we’ve been working with-Erica, Jonnathan, and Edison."

Roofing FAQs, answered by experts

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.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

Yes, thatched roofs are legal in most areas in the U.S., but you should always check your local building codes to ensure there are no restrictions in your particular area before installing one. Even where they are legal, you’ll usually need to apply fireproofing to the roof to keep it up to code. Keep in mind that a new roof might not increase home value as much if you choose a thatched roof, as they aren’t common in the U.S. and might not be as desirable to many home buyers.
