"Roof was 25 years old and was due for replacement. I also had old LP fiberboard siding that needed replacing in some sections mainly the chimneys. The rest was ok and I couldn't see spending the money to replace it all. George Keller did a terrific job on the roof and worked with me to match the LP siding using James Hardie siding. Carl the estimator took his time gave me a detailed estimate with pictures showing all the sections of siding that would be replaced. George Keller had done other houses in our neighborhood and one neighbor, an architect, used them, so that speaks to their reputation. I would highly recommend them. They are very efficient and neat and will finish your job in a day or two."

"Ervis and his crew did an outstanding job. The price was fair and the quality was excellent. My roof was replaced in one day! I had 4 contractors that gave me estimates for the roof replacement and Jersey Roofing offered the most competitive price. There was a supervisor at all times onsite which I liked. I highly recommend Jersey Roofing for A+++ quality and service."

Roofing FAQs, answered by experts

The average cost of a metal roof for a 2,000-square-foot home is $11,700, but your price can range from $12,000 to $90,000, depending on the number of stories you have, your roof design, and the specific metal you choose. Reach out to a metal roofing company to get an accurate estimate customized for your home.

Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.

You cannot replace granules that have been lost off shingles. The granule embedding process is part of shingle manufacturing, and once the bond holding the granules to the shingles has been lost, the granules are gone for good. Shingles with granule loss must be fully replaced to continue offering adequate protection.

If you're looking for a dependable and affordable option for garage roofing, asphalt shingles offer a durable way to blend a detached garage in with the surrounding residential aesthetic. If you're looking for a more durable and protective option because you're storing expensive equipment in your garage, consider metal roofs that perform well against snow, ice, hail, and heavy rains.

A roof overlay will last an average of 15 years, compared to the 20 to 30 years or more that a full roof replacement for a shingle roof will last. An overlay’s lifespan may be shortened even further if there’s underlying damage to the existing roof or structural problems with the roof supports.
