Customer Reviews
"Guaranty roofing is always excellent they have put a roof on my house twice in 30 years I had a problem they came out and looked at it and took care of it immediately I love this place they do great work and they're fast and efficient"
"Bought a house these guys roofed. After numerous attempts to explain they needed to fix a leak on the roof they did they finally came out and caulked a hole and called it good. After wanting a more permanent fix they cut away a lot of the siding along the roof line for no reason. Now the leak is fixed and I have a bunch of my siding cut out. The flashing did not need to be replaced. Don't use this company they are shady and a headache now I have to somehow redo my siding with estimates of 7k or more!!"
"Two trucks pulled up to do my roof in Early, Iowa filled with Hispanic workers that were meticulous, uniform, focused and in a time I could hardly believe, finished the most beautiful roof in one day! I have a small 1950s one story house and they completely cleaned up all trace of their mess. Very very impressed! Now I want my house sided."

- "I had a portion on my complex needing some siding work. Called and sent " Matt" out right away, had my siding up within the next week and did a wonderful job, keep in mind this was the highest portion of my complex!!! Thank you gaurantee roofing! Thank you Matt! Thank you for being awesome. My recommendations to you!"
- "Kasey and Kenny are helpful, knowledgeable and courteous. I had to wait a while for the siding work to be done, but it was definitely worth the wait. Kenny takes such pride in his work and it is much appreciated. I actually think he might be an artist in disguise."
- "Best price and staff very friendly"
- "Came out next day and took care of me. Has repaired my roof on two separate occasions over the last decade and have not been disappointed."
- "Guaranteed roofing installed our roof. Once snow came, anytime snow began to thaw, there was a leak that caused water damage in 2 places in our home. One ruined a ceiling and wall, the other area has made a hole in the ceiling. Upon calling them to help, they sent guys out to check it out and “fix” the roof about 3 days later. The men had to return several times because every time water thaws, the leak comes back. The leak is where the roof meets the flat roof, and despite “fixing it” several times, it leaked again the next year. They don’t guarantee that. We called back and forth several times and they didn’t directly answer for weeks, but eventually said they won’t pay to fix the interior destruction the leak caused, and all we can do is keep calling them anytime it does leak and they will look at it again. The biggest issue is it continues to leak when snow melts, so we cannot fix the interior ceiling and wall until the leak is fixed. We’ve found a different roofing company to assist."
- "I had Guaranteed Roofing install 3 windows in a bathroom renovation project. They did a fantastic job! They were professional, friendly and completed the project quickly. I will definitely be using them in the future!"
