I'd like to thank Will and his team at Keenridge again for everything they did. My roof was leaking and Will was there the next day to discuss my options. We ended up needing a roof replacement, and he gave me a very affordable estimate to replace all of it. Him and his team ended up taking off all the old shingles and some old wood, and replaced it with new shingles in the same day! I'm very happy that I found a company like Keenridge for my roof replacement!

Keenridge was super professional and they do excellent work. They completely renovated the exterior of the house. Roof and siding. The team is super responsive and highly communicative and did an amazing job. I will be recommending them to friends and family.

Everything was perfect, from the friendliness and professional introduction of Will and his company to the magnificent job on the roof. It looks beautiful. I especially liked the way they protected the rest of the house, the stoop, and walkways; and after the completion , checked the property for nails and debris. They truly respect their clients. Thank you.

Will and his crew did a great job on Warren's roof, gutters and gutter screens. They arrived on time each day and did the work professionally and quickly. We would definitely use them again.

What a wonderful company to deal with. From start to finish Will was nothing but top notch. They showed up when he said they would, did a great job and left everything so clean. I highly recommend Keenridge Construction Corp.

I’m so thankful that I stumbled across this company. After getting quotes from a few different companies, what stood out to me is the customer service I received before I even signed the contract. They were fast , efficient and had great communication skills. I’m so pleased with my roof repair. In a few months I’ll be calling them again for my extension!
