"Professionally handled"

Our roofing project was professionally handled and managed. Louis was attentive to our needs which in this case were fairly specific. He tracked down the materials and systems we desired and modified his pricing accordingly. Once the project started he as project manager stayed on top of things and was attentive when problems occurred. While the problems were minor and indicative of a project of this type, they were addressed and resolved in a timely manner.

"We highly recommend!"

We could not have asked for a more professional and expert completion of our roof and gutters! From initial bid, to dealing with the insurance company, to working with other subcontractors, to helping us understand our options, and to making sure all details were attended to, Chris Stevenson was on top of the project every step of the way. He was responsive to every question and suggestion. Most importantly, Chris took time to understand and comply with our special circumstances. The LCI roofing crew was courteous, efficient, professional and thorough. We very highly recommend Chris and LCI Construction!
