"I contacted Klestian from All Point Roofing company regarding the hail and wind damage on my roof. He went thru a thorough inspection on the roof and submitted the report with the pictures of the damages. Followed by explanation about the new roof installation process in details. The whole roof installation went well and on time. No mess left on the ground. Besides the good quality work he and his team did, I found that him being responsive and attentive to accommodate customer needs is one of the key factor that make me seal the business with All Point Roofing company!"

"Abe Nick provided extra services of replacing the ceiling tiles that had leak stains and sealing the windows that leaked. Had photos of old roof vs new roof where I can compare the quality of their work services . I like the way they presented during estimation showing the materials actual wood they are installing. My budget exceeded $3 grand out of $20 but truly satisfied of their work dedication. HATS OFF TO YOU ABE & NICK of ALLIED ROOFING."

"Very dependable and professional work. They were able to identify why we were having problems with roof, leaky window, gutters, etc and addressed/fixed the problem. Definitely had more confidence in their work than with any other contractor we have hired over the past 15 years in our house."

"It went well. They did a great job. We had a leak on the roof between the sky light and they did an excellent job at sealing it. They came back and resealed it so they sealed it twice. They did a great job and we have not had any leaks. I would use them in the future."

Roofing FAQs, answered by experts

Many roofers remove satellite dishes as part of their services, especially during roof repairs or replacements. However, they typically won’t reconnect or reinstall the dish. If you no longer need the dish, roofers can dispose of it, but for reuse, you may need a satellite technician to handle reinstallation.

Roofers can install roof vents. Updating, upgrading, or simply replacing your roof's existing vents is common when installing a new roof. If you're looking to upgrade your ventilation system with a powered version, a local HVAC professional can also help with the task. If adding roof vents to your home is necessary while installing an addition or during other renovation work, your contractor will handle or hire out the venting work.

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.
