"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

You should definitely be wary of roofing contractors who offer significantly lower prices than their competitors. Most roofers in the area are all dealing with the same cost of materials, and labor costs are often comparable, too. If they’re significantly cheaper than other companies around, it could be a scam. Read reviews and ask other roofing companies and contractors if they’ve heard of the suspected scamming company.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

The best roof replacement type depends on your budget and your particular climate, as well as your personal aesthetic. But in general, asphalt shingles are the best roof replacement type for homeowners looking for durability at a budget-friendly price. Asphalt shingles are the most common roofing material—cost-effective, easy to install, lightweight, and the perfect choice for handy homeowners.

EPDM roofing is a single-ply roofing material made of rubber, and a professional will install it in a single sheet and seal the seams. Built-up roofing (BUR) consists of multiple layers made from asphalt, adhesives, and roofing felt. A professional will construct the layers of BUR on-site. EPDM is easier to repair and has better resistance to extreme temperatures, while BUR is more fire-resistant and affordable.

The purchase price of 3-tab shingles is less than that of other material varieties, such as architectural shingles. However, 3-tab shingles generally last far fewer years than even the least expensive architectural ones. Other roofing types, such as metal or clay, also cost more than 3-tab shingles. However, if you plan to stay in your home for many years, the long-term cost of any of these options can compete with 3-tabs because of their longevity.
