Sorry about the error with my previous review. I had issues with my phone and accidentally hit the post button prematurely. JP roofing did an amazing and outstanding job with my roof. They were kind, respectful, and punctual, not to mention, professional.
We are very satisfied with the workmanship and plan on doing additional future projects. They
will be highly recommended to all neighbors, family and friends. Raymond and his team were awesome. Everything was done as promised, cleaning up everyday and arriving on time ect. Job well done.

Great roofing company. I had my roof completed June 2021 and still looks like new. I got estimates from 3 more companies and these guys were the best choice mainly because of knowledge, friendliness and professionalism. Not a lot companies know how to work with a flat roof that also had damage because of the previous incorrectly installed roof. There was one company that the owner ashamed us for the damage that the previous roof caused. It’s a family owned business and with people who know how to deal with difficulties from rooting to terminates. I liked their service so much I also got termite repair and 2 porches replaced from plastic roof to wood. Whenever I can I recommend them to other people. They also facilitated all the city permits. We are not stressed anymore during raining season.

JP Roofing was excellent! We are detail oriented professionals and are extremely satisfied with the professionalism, competency, and care given to our one hundred year old home. We were told by multiple other companies how difficult our roof would be due to the extreme pitch of the Tudor construction. JP Roofing did an amazing job and we are so very, very grateful for your hard work and the amazingly beautiful outcome. Thank you, in particular, to Raymond who thoughtfully guided us through every step of the process and ensured our complete satisfaction at the completion of the project.

The average roof replacement cost for a residential home typically ranges from $7,000 to $15,000, depending on factors such as roof size, chosen materials, roof pitch, and labor rates in your area. Premium materials or complex designs may increase the price.
The cost to replace the roof of a commercial building typically ranges from $5 to $12 per square foot, depending on several factors such as roof size, material, labor rates, building type, and local code requirements.
Several factors influence roof repair cost, including the extent of the damage, roof accessibility, material type, labor costs, and whether it’s a general repair or an emergency fix. Minor repairs can start around $150–$400, while major repairs may exceed $1,500.
Roof leak repair cost generally ranges from $300 to $800, depending on the size and location of the leak, the materials required, and labor intensity. Complex leaks involving structural repairs or interior damage will cost more.
Flat roof repair cost for commercial properties usually ranges from $500 to $3,000, depending on the roofing material (TPO, EPDM, PVC), the extent of the damage, and roof accessibility.
Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
