Don Muzzy Construction New Roof Leaked. Never Honored The Warranty Ironwood MI

I hired Don Muzzy Construction to install a new metal roof.

The new metal roof leaked two days after it was done.
Don Muzzy Construction came and put a patch on a vent pipe. The roof still leaked. After that he came and replaced a rubber boot on a vent pipe,The roof still leaked.
Then they came and replaced two pieces of metal.
The roof still leaked.
Then they came and put foam in the flashing and sealant on the screws.
The roof still leaked.
The bay window had metal installed on the top of it. That also leaked. In winter it leaked and when the water froze, the window cracked. This all happened over a period of 6 months.
He said he would come back and re-sheet the roof and replace the incorrect flashing and metal, but he never did.

Don Muzzy Construction never honored his warranty.
