Top 7 siding contractors in Longmont, CO

"If I could give Jeff and ATS Exteriors 10 stars I would! Literally the most honest and personable business owner I have worked with in my 22 years of homeownership. Jeff and his crew's hard work and dedication shines through in their quality of work. They pay attention to detail and go beyond the extra mile to get the job done right. Several of my neighbors have commented on how good my exterior looks. Cleanup every day was so thorough you wouldn't know work was underway. Thank you, Jeff!! I highly recommend ATS Exteriors Roofing & Siding!"

"I was very pleased from start to finish working with ATS exteriors. The crew was great bringing to my attention and fixing issues on this project. This type of work ethic is not often seen these days. The entire crew was efficient from stripping down the old siding, putting up the new, fixing the problem areas and great clean up. The price of the project was exactly what I had anticipated. I am so pleased with them that I am having them return to replace the gutters, soffit and fascia. Thank you so much for your hard work."

"I contacted ATS Exteriors Roofing & Siding to inspect my roof and siding. Jeff came out promptly and spent about 20 minutes doing a thorough inspection. He explained that my roof was in overall good shape but pointed out several areas on both the roof and siding that needed minor repairs. He also showed me that my 23‑year‑old siding had never been nailed down correctly, which I would have never known on my own. The next day, I received a detailed estimate along with photographs of every problem area. I approved the work, and the following week Jeff sent his crew to complete the repairs. The team finished everything in about half a day. Jeff, Rebecca, and their foreman were all very easy to work with. I appreciated their professionalism, clear communication, and attention to detail. I would definitely recommend ATS Exteriors for any roofing or siding projects"

"Outstanding Service All Around!!! I could not be happier with my new roof and the excellent customer service that I received from everyone at ATS Exteriors. When a hail storm hit my neighborhood I contacted Jeff at ATS Exteriors and he came out that same day to conduct a free roof inspection and identified signs of hail damage. After I submitted an insurance claim, Jeff took the time to meet with my insurance adjuster when they inspected the damage even though it was on a Sunday. My claim was approved and Jeff and his team helped me select the best roof shingles and materials for my needs. They were able to complete my roof in one day and the quality of their work exceeded all my expectations. I highly recommend ATS Exteriors to anyone reading this review as you will not be disappointed."

"We had an excellent experience with Jeff & Rebecca! Siding needed a complete overhaul and I wanted someone who was listed on the HArdie site. So that's how I found them and they did a knock-out job. Jeff dones't stop once he started and he was done a day before I thought he would be. I will recommend you guys to my friends!"
