A few years ago we had Synergy replace our roof, siding and eavestrough. We were so pleased with the completed project that when we decided to replace our front and back doors plus a couple windows, we knew Synergy was going to be our first phone call.
From the time we placed the call to the time we had our project completed, the interaction was exceptional. Joe who quoted us on our project was professional, kind, easy to talk to and kinda funny! He assured us the dudes who would be doing the install was just as nice and very good at what they do. Joe was right. The finished product was perfect and just what we wanted.
What an fantastic company and great bunch of people. 100% class act all the way.

Only thing was they left a bit of a mess behind. I found quite a few roofing nails and old shingles left behind in my driveway from a likely quick cleanup. Luckily I managed to pick them all up before any flat tires. Other than this minor issue I will definitely use Synergy again for any roofing needs!
The team at Synergy was very friendly and respectful. They finished my roof in a single day and were very efficient with their time. They were not too disturbing, as I was able to work from home the whole time with no disruption.
The only issue I had was getting the bin removed from my driveway in a timely manner.
