John Keller Roofing finished our beautiful roof recently. What a wonderful job John's crew did, from being on time, doing a fast and excellent job, to clean up. They were done in 1 day, and they have followed through on every thing, in a fast and efficient way. Lisa, the person I communicated with, was very professional, and kept me posted every step of the way. I highly recommend this company for your roofing needs.
John’s team was hard working and most professional. I’m a repeat customer and I’ll use them again. Great roofing company!
All thumbs up for our experience with John Keller Roofing! Came highly recommended by a neighbor. Price was very competitive, work was excellent, put in long hours to get our total roof replacement done right in the middle of new Hurricane Milton clients. All permitted, to code, inspected, and warrantied. Payment after completion allowed me time to get my financing together. Could not be happier. Call them FIRST.
Had our roof replaced in July 2025. Shingle and underlayment materials arrived on time on the day scheduled. Crew arrived on time and knocked out the roof in a couple days. Had a sudden rain storm come in and crew was quick to get the tarps out and cover the roof so no damage inside. John, himself, was present several times through the process and assisted as needed. I will recommend this company.
Do not trust this company. As with other reviews, the roof of my house was replaced less than a year ago and already has a leak. John and his office do not know how to prioritize, schedule, or return calls. His crew is incompetent and disrespectful of the property. John will blame everything except himself. He will find any reason to not honor the warranty. Find a more established company with a better reputation.
