We partner with GAF Energy, with an experience of 135 years, provide quality solar panel installation at affordable costs along with the strongest warranty.

Why is Solar Shingles a Revolution?

Solar Shingles are preferred today by most, even more than solar panels. This is because it is just like a conventional roof and fits well with the aesthetics of a house rather than a solar panel that is mounted on the roof. There are majorly two types of solar shingles.

Recently we have had a BRYANT AC unit installed with them. Called for a quote on a weekend and loved their customer service. Carlos had a payment plan, installation date and kept us updated on every single question or concern. Everything was installed efficiently, professionally and with care. David and Carlos were both amazing in what they do and even left several ways to contact them for any question, comment or problem that may arise ! A new highly advanced smart thermostat was installed along with new ducts that were very much needed. Goodbye 23+ years old AC and hello to this new AC !! Thank you to everyone working at Grand-mark Service Company ! Keep up the amazing work !

Grand Mark did a superb job of replacing our old shingles, and installed not only a new roof, but added additional ventilation for the attic, added a new layer of blown insulation in the attic space, and installed new gutters over the main walkways around the house. At the end of every work day, they cleaned up all of the materials from around our yard. The entire project took roughly a week to complete, and we are very happy with the work they performed. We have yet to need to use our air conditioning, as the interior temperature never gets above 75 degrees, thanks to the insulation and new GAF cool shingles they installed. If you need a new roof or gutter system installed, I highly recommend them.

We wanted 1 company to do our roof, AC and solar panels. Called several companies but found that Grandmark energy was the best for us. Had the pleasure of working with Todd and Justin on our projects and couldn’t have asked for a better duo. They took care of all our needs/wants and more. Had our whole house reroofed, new AC unit w/all new duct work, solar panels, rain gutters(all around the house as needed) and also had some electrical issues in our house and they also took care of that for us too. They were clean and professional. Todd and Justin always let us know what was going on what needed to be done. Very easy to talk too. The best part of it all, is our house looks beautiful and they got the jobs done before the estimated finish date. We couldn’t be more happier. Thank you Todd, Justin and all of Grandmark!
