Jolly Giant Roofing LLC in Bozeman is the best! They got right to work on patching my roof in a very efficient manner. Until my shingles became available, they put on a temporary cover so my roof and ceiling didn’t get ruined.

Jim Keena
We had an exceptional experience with every member of their team. They were professional, efficient, and did an outstanding job replacing our roof. The new shingles look fantastic, and the cleanup afterward was through.
Marc Leonard
Garret and the crew at Jolly Giant roofing are fantastic. I had some roofing work that needed to be addressed in short order to satisfy a real estate transaction and Jolly Giant Roofing rose to the occasion. They were reasonably priced, punctual, and had fantastic communication. They took the stress away from a tight turnaround deadline. I will absolutely be using them for my future roofing needs.

As a local realtor, I can’t say enough good things about Garrett and his staff at Jolly Giant Roofing! They completed the roof in just one day to keep a real estate transaction on schedule. Their professionalism, communication, and quality workmanship made the process seamless. Highly recommend them to anyone needing dependable roofing services!
Matt KREKELBERG
I have known Garrett from Jolly Giant Roofing for over 2 years now. My experience is that he is incredible hard working and always wants to delight the customer. Whatever the size job, he treats his customers as if it's his only. I work for Malarkey Roofing Products, I am so grateful that he supports my family and Malarkey Roofing. There are many other brands contractors use because they are cheaper and less quality but Jolly Giant Roofing uses the BEST shingle on the market. I know his customers are getting the BEST value. Give them a call!
