Green Attic was fantastic. They consistently underpromised and overdelivered.From when the Dennis the estimator came out (early) and was extremely knowledgeable and professional to when Marco setup the date and got the team out here (earlier than promised) to when Riccardo, Jorge and Juan knocked out the repair and fan install in record time. House was spotless when they finished (finishing early) and they costs were less than they estimated as they discovered some quoted repairs were not needed. I would NEVER have known and they were very honest.

Use these guys or wish you did!

They finished insulating my old roof and fix all the items I need to update my new house. They’ve made couple mistakes but they were able to correct it and clean up the mess. Emilio and others made sure everything is up to their code and I am happier than ever. They are professionals and I 100% recommend.

I had Green Attic out about a year ago to install insulation, some vents and solar fan. The temperature regulation in the house has been great, and my energy bills are much lower. Today Julio Robles and his partner came out today to inspect my chimney leaking. He inspected the old work and did a great job on the roof and ventilation. I would recommend them for roof issues as well as any attic issues.

Extraordinary job done on renovating our roof. We had the asbestos roof tiles on our family home in Park Ridge, and it is replaced now with asphalt shingles. We are extremely pleased with the quality of materials used and the execution, speed, and professionalism of the job. The entire project was completed even well before the agreed deadline. Clean, fast, and high-quality work. The guys went above and beyond, addressing everything we agreed upon in record time. I can only recommend this team, as the difference in roofs installed by Green Attic Roofing compared to others is truly noticeable. Therefore, a warm and sincere recommendation to anyone considering replacing or installing a roof.

Patrick is a very honest person and his associates are experienced craftsmen who know exactly what they are doing. The complete work was completed according to the agreed schedule and the price they gave me was more than fair. They installed a new slate tile roof. I highly recommend Green Attic Roofing.

The crew was knowledgeable about the unique requirements of Tesla solar roofing, ensuring that every detail was meticulously handled. They walked me through the process, answering all my questions and providing transparent timelines and cost estimates.

What truly stood out was their commitment to quality. The installation was seamless, and the solar tiles blend beautifully with my home's aesthetic. It's clear they take pride in their craft, as the roof not only functions efficiently but also looks stunning.

What Is Commercial Roof Insulation?

Commercial roof insulation is a protective layer added to your roof system that reduces heat transfer, keeps indoor temperatures stable, and improves energy efficiency. By minimizing heat loss in winter and heat gain in summer, it lowers operating costs and helps extend the life of your roofing system.

Stops condensation & heat loss

Flat Roof

Boosts energy efficiency & meets code

Low-Slope Roof

Controls temperature and prevents ponding water
