Frank did an exceptional job cleaning my roof and gutters. He is a very polite young man, and did an excellent job. I will definitely be using your company again and referring others to you as well. Thank you.

Joseph contacted us immediately and he felt he was able to commit to the work and a quote with the pictures we provided. He was able to confirm the problem and make the repair in one visit at a reasonable price.

I needed a small siding repair following Helene. Joe got back to me within about 15 minutes and was out the next day. If I need more siding work or roofing work, I’ll definitely call him again.

I had an amazing experience with Joe with Generation Roofing. Shingles had come off my roof from the hurricane and Joe was out there the next morning first thing with new shingles and also nailed my siding back which had come loose from the storm. I gave my coworker Joe’s info as he also had the same issues as me with his roof. He also said he had a wonderful experience with Joe. Joe explained what he was doing and also check the whole roof to make sure there wasn’t other areas on the roof that had to be repaired. I highly recommend Joe and his team as they respond right away and they are very fair with their prices! Well done Joe!

Contacted Joseph for repairs on an older home. There was siding repair work needed as well as new metal roof on carport. He responded within minutes to the request through Thumbtack and was on top of the project from start to finish. Work was great, punctual and reasonable price for a great job. Would definitely recommend his services.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
My pricing is competitive and often more affordable than most established roofing businesses. What sets us apart is that I never hire subcontractors. Every roof is installed by in-house employees personally trained by me. This means you get higher-quality workmanship at a fair price, with the peace of mind that comes from knowing your roof is being installed by a team I’ve directly trained and oversee on every project.
What is your typical process for working with a new customer?
We will inspect the roof and provide an honest assessment—if a repair or tune-up will extend its life, we recommend that before a replacement.
When replacement is needed, we give a clear written estimate with multiple product options and warranties.
We purchase all the materials to ensure quality and consistency.
We don’t require down payments on standard-sized jobs.
During installation, I work alongside my crew and make sure the property is cleaned daily.
Every roof comes with a lifetime labor warranty that matches the manufacturer’s warranty, plus free follow-up inspections for peace of mind.
What education and/or training do you have that relates to your work?
My training in roofing started long before I ever thought about running a business. I grew up in Micronesia as my father was a missionary there. From a young age I began helping my father with roofing projects here in the U.S. whenever he returned from the mission field in Micronesia to raise support. That hands-on experience taught me the value of hard work, attention to detail, and doing the job right the first time.
I later studied biology and business at Bob Jones University, but ultimately decided to pursue roofing full-time rather than sit behind a desk. I believed my time and energy were better spent building a trade, serving customers, and developing a business.
Today, I combine decades of hands-on experience with a deep commitment to doing every job with integrity.
