What kind of contractor can redesign gutters/roof drainage?
I'm in Maryland, and in our recent record snowfall had enormous ice dams. One area in particular is a problem: half the house roof and half the garage roof both drain to just a very small (2 foot) section of gutter in a corner by our front door. This gutter gets overwhelmed. In the winter, it get ice-dammed and the constant drip and refreeze makes our front porch a permanent skating rink. In the summer, so much water rushes down this one corner that it has actually undermined part of the driveway.
What kind of a contractor would I call to see about redirecting the water flow somehow? A roofer? Gutter person? Somebody else?
