What our customers say

 Matt W., Oregon House

“Westhaven installed our new system in one day. The installation was clean, professional and the installers seemed to enjoy not only the job, but the company they worked for.” 

Brian C., Arbuckle

“These guys are professional, courteous, and up-front about everything. Colby was first up on the roof who identified and photographed cracked tiles and fixed them. Jason kept me up to speed throughout the installation and answered all the queries I had.” 

Christina M., Plumas Lake

"The communication was great throughout the entire process, with status updates. The installation team was amazing and took the time to answer the questions I had. They also answered the questions I didn't know I had!"
