Verified record
GLS Roofing and Construction, at 14 Bows Lane in Avon, handles roof leaks and repairs, and its Angi and HomeAdvisor pages show 4.9 stars from 10 ratings, with 20 years of experience, free estimates and a Spanish-speaking crew. The written reviews run from April 2020 to February 2023. In a May 2021 review, a customer with an emergency roof leak said the crew came out right away to estimate, returned 2 days later, earlier than planned, and finished that day, with Luis working out the problem. An April 2020 customer said missing shingles from a wind storm were replaced quickly, the leak stopped, and the flashing around the chimney was replaced, at a reasonable price and with no mess. A September 2021 customer had a shed roof replaced and said the crew cleaned up everything, including the branches they had to cut to reach it. In March 2021, a customer noted a $290 job with a senior discount. A February 2023 customer mentioned some language barrier but said it was overcome.
Competent, Punctual and Efficient. Some issue with language barrier but able to overcome. Great Job!
Great work
Luis is a very hard worker who did a great job.
This company was great. They replaced my shed roof quickly, and cleaned up everything afterwards, even the tree branches they needed to cut to get at the roof.
Had an emergency with a leaking roof. They came out right away to give an estimate and returned 2 days later (early) and finished the project that day. Luis seemed to really know what he was doing, figured out the issue and the solution Great work! I am going to have them come back for a few other projects that I need help with.
