"After hiring Buck to replace our roof and having such a great experience we finally decided to replace our deck. From the quoting process through the project completion the team was amazing. Despite some hiccups in the permitting process, Rick made sure we had clarity on the scope, financing and terms and then the guys did a great job building the deck. We had one small cosmetic issue when it was done, and not only did they come out and take a look but offered to make it right immediately with no questions asked. Unfortunately our siding is fairly new so there isn't anything else we can hire Eagle Siding to do but if we ever build a home (or move into one that needs some work) they will be our first call."

"This was a 2 day challenging fascia replacement job involving a several person crew supervised by Lakewoods' owner, Shawn, and his right hand man, Ho. All the work was accomplished to my satisfaction in a timely, efficient, and professional manner. I would highly recommend Lakewoods and Shawn for siding and roof work requiring a high level of competence."

"We were really impressed with the care that Boe took to make sure that our custom fitted deck was exactly right for our needs. He & his team did such an amazing job. We just love our new deck! It was a challenge to figure out how to get the most out of a small space but Boe was able to figure it out. The crew was so nice to work with. We would highly recommend them for any job large or small. Skilled perfection & hands down the best in their profession! We just love our deck with the floating walkway! I was so happy with their work, customer service and communication from their team, that when a hailstorm came through, they were 1st people I called. They did a thorough inspection and provided enough information to call in a claim. They met with the insurance company and now we have a beautiful roof that really enhances the curb appeal. During the install they were very mindful of all of the gardens I had around my home. There was a mother mallard on a nest beside the house and they were so careful not to scare her. All the ducklings have since hatched and we've spotted them in the pond at the back of our property. Proficient Construction did a great job cleaning up and was very thorough throughout the install. They are currently working on our windows and gutters and I look forward to working with them in the future. Thanks Boe!"

"I have to say Steve, Lisa Gruye and they're team are tops when it comes to professionalism, quality, and customer service for home improvement projects. I needed 11 windows and a storm door installed as a home improvement project and Pro Exteriors delivered what they promised. Pro exteriors got the job done on time and in budget. I would not hesitate to recommend Pro Exteriors and will be calling them again if I need work done. Excellent job! Excellent service! - Dan S."

"It couldn’t have gone better! The crew came tore off the old roof. After they got the old roof off a storm front came through. These guys were up on the roof with a giant tarp strapping it down makin it water tight and I never had a single leak. It’s a pity that it’s a flat roof because it’s truly a work of art and no one else can see it. I’m exceptionally pleased that they have offered to come back in the spring to make sure that everything is still OK. I only have one roof , but if I had another I wouldn’t think twice about hiring them again. They were easy to work with and really know their business."

"It was a pleasure working with the contractors at Ridge Brook Construction. They were very responsive, whenever I had questions, and made sure all the work was completed according to my home owner insurance company's schedule. I'm very pleased with the quality of the work, the new shingles look great, and the leaf guards are a much needed addition. The crew that did the roof work were fast and did a great job of cleaning up, too."

FAQs for flat, foam, or single ply roofing installation and replacement projects in Cottage Grove, MN

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
