Recommended Customer Reviews

One of only a few of many roofers who texted
me with a response. Not that difficult of a
downspout replacement job. They just do
Roofs.

We had a few leaks from the roof of our newly purchased house when winter storm hit. I found Javier, JT roofing, from Yelp. Javier was punctual, professional, customer focused and very friendly.
After the estimate he quickly patched all leaks between the storms. Moreover, I asked my general contractor to fix one of the leak since it came from newly added plumbing vent. Javier adjusted his estimate even thought he found that leak. I thought he was very honest and fair. Moreover, he sent me all pictures of the patches via text. I would definitely recommend using JT roofing. I will consider JT roofing when we replace the roof next time. It was pleasure working with Javier!
By the way, he even shared his contacts for fixing other part of my fixer house. Javier went above and beyond!

Great job by Javier Tapia and his team. We had a new roof and gutters installed and they did an excellent job!!!

5 stars for honesty, thoroughness in assessing a problem and recommendations. Would for sure trust Javier for future roofing needs.

Jt roofing is a family owned business. Rock solid estimates and all work done beyond code and in a workmanlike manner. Give these folks your business- I'm glad I did.

Frankly, if I could rate Javier a 6, I would do so. Honest, diligent and excellent work. Our roof is beautiful. Highly recommend this company.

Javier is efficient and professional. The entire experience from coming to our home, giving us a quote, ordering the supply and installation was seamless. Javier and his crew showed up on time and completed the project with perfection. The gutter shield were installed without only issues. The contract was signed via DocuSign. Love the paperless approach. I highly recommend JT Roofing!

Truly a beautiful job, thank you! I've had a lot of work done over the years and I can say I've never had the pleasure of working with anyone as professional, gracious, and easy to work with, I'm extremely impressed with the quality and thoroughness of the work. He and his team installed a new roof on my detached garage which was in terrible shape, replacing areas of dry rot and patching knots that had rotted out -- roof is perfect now. He repaired damaged seals on the main house, and even took before and after pictures to show the repairs where I wouldn't be able to see.
I should also mention, he had the best price of three bids.
I can tell you take great pride and care in your work and it really shows, I appreciate it so much! Thank you!!

Due to the heavy rain in December, my tenant informed me that the roofing was leaking. It was around Christmas time and the roofing companies were very busy. I contacted multiple roofing companies and didn't get much responses. Then I found JT Roofing on yelp with good reviews and decided to send a yelp message. Javier replied my message quickly and set up a time to come and check out the roof.
Most companies gave you a time window to come and are normally late leaving you wonder whether they are coming or not. Javier gave me a time to come and also let me know by email that he was on the way. I showed him the leaking area. He checked the roof carefully and found some rotten nails and other things that could cause leaking. He caulked those areas up. Also he left the root caulk tube to us as this kind of root caulk is hard to buy in Home Depot or Lowes. He was so nice and didn't charge us a thing.
Luckily the roof has not leaked yet in this week's heavy rain. He also gave us 2 quotes to fix up the leaking area or fix up the whole front side which we are still trying to decide. We are really grateful for Javier's help on keep us worry free in this raining season.

When the rainy season started, we contacted JT Roofing again for gutter cleaning and gutter guard installation. We did not know much about gutter guards, and Javier recommended one that is reasonably priced and widely available to purchase for us.
Javier finished all the cleaning and installation work in two hours. He also helped check the roof and chimney again, and patched some deteriorating caulking for us.
It is three weeks after the installation now. Everything has been working great! No more falling leaves trapped in the gutter, and we can see the rain water flow down the gutter very well every time it rains.
