Asphalt shingle roofing question?
Asphalt shingle roofing question?
I am in the process of replacing an old slate roof with an asphalt shingle roof, located in the northeast.
The slope of the main roof comes down over a few flat porch roofs.
The current slate roof has metal flashback (pieces of metal over the edges), over the porch roofs, to prevent ice dams.
The company I have hired to replace the roof is telling me I don't need flashback on the edges over the porch roofs, because I have a smaller roof and asphalt gripes the snow better. They are also saying it could cause problems if I put it up as water can get behind the metal. Is this true or are they just trying to avoid the work?
The old timer slate roofer who has been helping me maintain the slates however is telling me that if they don't put metal up I am going to have large ice chunks building up and puncturning the flat roofs.
So, I was just hoping to get a few other opinions on this. Thanks!
