Roof and gutters have been replaced twice over the years by MAC no problems with the roof. The gutters are low at the corners, fill with water and leak high on the seam. This was a problem both times at several corners. MAC was made aware of this and tried to seal seams several times. Never the less, the corner directly above my front door poured water for 15 years. Last work was done 1 or 2 years ago. Also had them replace some rotted wood, and the guys didn't tell me about another piece that was rotting and unpainted. (Large piece plain sight ) Roof looks good, but I am not a roofer?
