Darren Schulz

President of Duro-Last

I am always pleased with Sentry, when I need them they come out promptly, the crew is always courteous, respectful and have great skills. The roofing crews represent Sentry Roofing very well. I know that the job will be done right, then receive a call to follow up with the repair to make sure everything is taken care of. Respect goes a long way with me and I appreciate Sentry Roofing for the care and respect they have provided me regarding the Hampton Inn.

Ralph Shrader

Superintendent, MSD of Warren County - Williamsport, IN

Since Sentry installed our roof 19 years ago we have not had a single issue with the roof system. On a couple occasions, we needed to make modifications to the roof and Sentry was there to immediately help. Based on my experience as a general contractor and owner I feel this is one of the very best roofing products in the industry and Sentry Roofing has earned my complete confidence with their professionalism and dedication to getting the job done right. I trust Sentry completely and will be having them install my next roof.

Scott Degraf

Owner & General Contractor, Heart of Chicago Motel - Chicago, IL

Safety is a top priority for Sentry – it’s the first thing I see at the job site. Making sure everything’s well marked off, roped off where it needs to be, everyone is where they need to be, all the lifting and hoisting is done properly, the roof is very clean at the job site no tools and clutter laying around. Everything’s in its proper place all the time.

Jeff Coffing

Director of Maintenance, Covington Schools - Covington, IN

I will give Sentry absolutely 5 stars. These are the guys that need to do your roof. They know what they’re doing and they know how to put it up there. They care and they’re just nice people to work with.

John Benson

Facility Director, Bible Baptist Church - Kokomo, IN

I have worked with a fair amount of commercial roofers over the years and I would put Sentry Roofing ahead of all of them. They have been my best experience with a roofing contractor without a doubt. When Sentry came to me, they said they would do a professional job and they could not have been more right.

Rob Albers

Project Manager, Horve Builders - Forsyth, IL

I have to really commend Sentry for the communication they had with us and the professionalism of the crew. I didn’t even know they were up there working half the time. They weren’t loud. They were professional. They cleaned up. They were always in contact with me. I trust Sentry. They stand behind their work 100%.

I can’t say enough about Sentry Roofing! The service is just superior, the guys are prompt, courteous, and they always do a great job with no disruptions to our students or staff. Tim is very honest, the prices are reasonable and I’ve been thrilled working with him. I know whenever I need him he’s just a call away. I’ve been very very happy that we’ve chosen them as our roofing contractor.

Curt Spaur

Facilities Director, Hoopeston Area Schools - Hoopeston, IL

Sentry did an amazing job with the repair to our church. I called in, a day later the guys came out, fixed the roof and that was that. We’re very pleased with everything.

Brian Clem

Trinity Lutheran Church - Danville, IL

Sentry was higher than the other estimates I reviewed but my satisfaction with the outcome of the project far outweighed the price. We smile every time it rains, the roof is great!
