My house has a large dormer section above the front door. There is a "V" shaped diverter on the roof above to keep rain water from falling directly over the front door. At a later date gutters were installed on a section of roof at the first floor level to catch rain water from both that level and the second floor level.
Since then ice dam problems have started to occur at the second floor level since snow builds up, held by the V shaped diverter. Would it be a good idea to remove the V shaped diverter so snow and ice can slide off more easily?
Don't let the weatherman string you along. Stick to your lawn watering schedule until it actually starts pouring.
