About us

Three Mountain roofing

Lee and Alisa Anderson are the owners of Three Mountain Roofing. They wanted to take this opportunity to let you know what separates them from the other roofing contractors out there and why you should choose Three Mountain Roofing for your upcoming roof replacement job. 

Lee has been a carpenter for 30 years and a professional builder for the past 26! He has built in the high country of Colorado, the mountains of western North Carolina, and has been in Vermont for 14 years now. 

He knows what it takes to build and protect homes from snow, ice and rain in the most extreme mountain environments. 

We have used many different products over the years but have not found a shingle and system that is better than what Owens Corning can offer. 

We feel so strongly that we approached them in 2018 to become one of their Owens Corning Preferred Installers. After a thorough vetting process to make sure we measured up to their standards, we were awarded that status. 

In March 2021 we were elevated to Northern Vermont’s FIRST Platinum Preferred Installer! It’s tough in Vermont to know who to trust with your home to get the job done right, as there is no general or sub-contractor licensing, so your end product is only as good as the contractor you hire, and to do so all you have is your gut, referrals, and certifications to go on. 

Not only are we Northern Vermont’s FIRST Owen’s Corning platinum Preferred installer, we are also BBB Accredited and a member of the National Roofing Contractors Association

As an Owens Corning Platinum Preferred Installer, we can offer several superior warranty options that most cannot. We will take care of the warranty registration process for you, and as our standard warranty you will get the Platinum Preferred Warranty. 

We were the FIRST installer in Northern Vermont that can provide this warranty!
