Green Leaf was great. I got 5-6 quotes on Homestars, threw out the high and low, and ended up choosing Green Leaf.
The main factor for choosing them was the honest answers to my roof questions. I spoke with Paolo and he answered all my questions about metal roofs, solar panels and price matching a competitor.
My roof had 5 layers of shingles on it, which are fixed costs for removal and disposal, there's no possible costs savings there. I also have a 12/12 pitch which is more challenging to work on.
They did a great job and even helped patch a window leak on the third floor.
I would recommend Green Leaf and use them again in the future.
