For me, quality is worth the extra cost. Every area they touch I know I will never have to worry about again. That's good piece of mind.
These guys care about doing the right thing - That's so hard to come by these days! They were honest about the work that needed to be done and they didn't have any hidden costs and, best of all, they actually showed up when they said they would.
Regarding staff, they are adequate.
The roof they installed on my house looks great. The workmanship was of high quality, the price was reasonable, and most importantly they stand behind their work.
