I like the fact that G&G lived up to their commitment to complete the project when they said they would, used high quality materials and cleaned up after they were finished.
Communication was good, the installers worked hard and were safety minded. The finished product looked good and the value seemed very fair.
Communication about timing and attention to detail.
None
We had a good working history with G&G and hired their services primarily due to their 50-year warranty support. Other companies bids came in cheaper(<$53k) but we feel solid in our decision.
The office personnel were very helpful, the Installation crew was also great. Really everyone I dealt with at G&G were helpful and professisonal. The roof installation itself seemed to reflect good workmanship. Overall a positive experience.
