"When I was advised by my landscaper company that I had loose shingles on my roof, through a referral from a friend, I called Clancy Malone from Atlas Roof & Exteriors. Clancy reviewed my roof and advised me that I have some severe hail and wind damage. Upon notification to my Insurance Company, I was advised that my claim is justified. From that point Clancy advised me that his team could install a Lifetime Dimensional Shingles, that has the longest warranty in its class. The work was completed within 3 days and I cannot be happier with the courtesy and professionalism that Clancy and his crew afforded me. I would use or recommend this fine company to anyone needing professional roofing replacement ! Thank you again, Clancy Malone and The Atlas Roofing & Exteriors Company. Best, Larry R. Cutler"

"While removing the old roof, the aluminum coverings on our mansard roof dormers were damaged. The roofing crew attempted to repair the damage but the result was not satisfactory. As compensation they deducted a small amount from the total bill."

"Our roof replacement went very well. Shane Matheny was great to work with. He was always on time for our appointments. The price was fair and lower than the other 2 bids I obtained. After I signed the proposal, the work was scheduled and completed within a few weeks. They completed my roof in one day and did a great job cleaning up the job site. I would certainly use them again and recommend them to others."

Roofing FAQs, answered by experts

The number of roof vents necessary for a 2,000-square-foot house depends on several factors. The calculation depends on the net free area within the attic and whether your municipality requires a 1/150 or a 1/300 ratio of venting square feet to attic square feet. If you install vents with a square-foot opening of one, you'll need either 14 or seven exhaust vents and an equal square-foot amount of intake vents.

Wooden roofs require regular maintenance, are prone to rot and mold, and are frequently the target of insect infestations. Natural wood is also excellent at absorbing and storing moisture—not a positive. In climates where the weather shifts dramatically, the wood can also crack, split, or warp.

The most obvious and severe sign of a roof leak is the presence of wet spots on your ceilings, specifically on the top floor of your home. You can also identify a roof leak from your attic if you see sagging insulation or if you notice mold growth or water stains on the rafters or the underside of the roof deck. From the street, look for cracked or missing shingles, moss growth, and shingles that are curling upward, all of which can suggest a leak.

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.

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.
