I had a roof leak during heavy rain back in February 2024 and reached out to multiple roofing companies to get it checked out. The first roofer showed up, glanced at my house (didn't even go on the roof), and immediately said I'd need a full roof replacement--based off Google Maps. That didn't sit right with me. The second roofer came out and said they'd need to use a drone (and charge for it), and also suggested I'd probably need a new roof. Again, no real inspection. Then I contacted JNSA Roofing, and this is where things changed. Nathan's dad--the founder--came out personally. Old school, straightforward, and clearly takes pride in his work. First thing he said was basically, "How can they say that without even going up on the roof?" And then he actually got up there and inspected it properly. He identified the real issue and recommended a repair instead of a full replacement. The work included cleaning debris, pressure washing, fixing problem areas, sealing seams, and applying a silicone coating to the flat roof with proper materials and standards. They also provided a 5-year workmanship warranty. Bottom line: they did a great job and the leaks completely stopped. Later on, I noticed water near my back window and thought it might be related to the roof. I called Nathan in April 2026, and he came by to check it out. He showed me it was actually the window caulking and explained exactly what needed to be done to fix it. Both Nathan and his dad were professional, easy to work with, and clearly know what they're doing. I'd absolutely use them again for any roofing needs--hopefully not for another 15+ years. read more

We had an abysmal experience with Nathan and his son(s) from JNSA. We contracted them for simple repairs to a flat roof that had undergone soffit extensions and fascia replacements. After 4 major leaks which caused extensive damage to our wood floors in the kitchen, dining and living rooms, we contracted a new roofer. They showed us multiple problems with Nathan's work: 1) roof sheeting had not been torched down. 2) sheeting was left unattached to the subroof structure and lifted away with almost no force. 3) seams were crooked and uneven. Some had large gaps where water could seep under 4) subroof was not leveled properly leaving areas that would eventually break apart. A $12K job that cost us $20K to do over. Existing works had to be completely removed and replaced. Ruined $8K in custom aluminum fascia that we had to purchase and wait 4 weeks to be replaced, before the new contractors could start again. Over $4K needed to sand, stain and refinish our hardwood floors. We were told they used a roofing technique that was the bare minimum and would never meet basic code regulations. read more

Here's the summary of this review: You only want JNSA to install or fix your roof. Period. I've had the privilege of working with JNSA for the past 20 years. JNSA has: *Saved me thousands of dollars by not doing unnecessary, extra work *Used technologically advanced materials that are long-lasting *Always used the best approach for the job (every roof is like a fingerprint-- it's unique) *And have been prompt, thorough, and ultra-professional in every engagement. Until I hired JNSA, I never knew roofing could be this professional and advanced. The reason why is that JNSA does ultra-quality residential and commercial work. They treat residential customers' roofing needs as if they were large-scale commercial jobs, bringing exacting quality and care to planning, installing, repairing, and maintaining all types of roofs. Go with JNSA if you want the best, prompt, on-time service; the best approach to fixing or installing a new room; and the absolute confidence that you have the best work that will last --all at a fair and reasonable price. I cannot recommend Nathan, Vess, and the team more highly for delivering absolute quality and the highest level of service for their customers. Do not hesitate to call them. read more

JNSA Roofing is a company I have done business with for a number of years. They were referred to us by a respected contractor who uses them for all of his projects. Not only did they do a beautiful job on our house for a very reasonable price and on a very speedy timeline, but my wife (who is a real estate broker) has recommended them for a number of roofing jobs and all of her clients have been very pleased. Recently, after the heavy rains, we had a small leak around a skylight. We called JNSA, and Nathan came within 24 hours and fixed it right away. I highly recommend them for any roofing work you might have. read more

I called Nathan to do a roof inspection of my house after I discovered a fallen shingle back in May. It was very easy to reach him and get an inspection time scheduled. When he arrived he did a thorough walkthrough of the roof and saw that there weren't any holes in the roof, and he suspected that one of my contractors had just left a loose piece that eventually fell onto the driveway. Nathan's professionalism during and after the inspection was definitely appreciated, and I'll be calling him back once I need roof repair and replacement done in the future! read more

JNSA Roofing - Our new roof! - Roofing Near Me

I bought a house that recently had work done by this roofing contractor and it was not done correctly. As you can see in the photos, the perimeter edges are completely exposed with large gaps that will allow moisture and water intrusion into the roofing system and probably ruin the foam and plywood sheathing layers, jeapordizing the waterproofing integrity of the assembly. I tried reaching out to the contractor to ask them to repair the work under their workmanship warranty, but they have been ghosting me and failed to respond. After multiple texts, phone calls and emails, I have up. If I could give 0 stars I would. DONT EVER use this roofing contractor. read more
