Ice Damming
Ice dams are the accumulation of ice at the eaves and valleys of roofs, and in some winter produce considerable problems. Insufficient attic insulation or attic ventilation can activate roof snow to melt and move down to the eaves, where the roof area is cooler and the melting snow adheres the roof. Subsequent melting activates water to swimming pool behind this dam and sometimes the water leakages in between the shingle layers, dampening the roof deck and possibly the ceilings and walls noted below.
Interior damage induced by ice dam. What To Do?
1. Completely seal all ceiling penetrations such as lights to keep warm, damp air out of the attic.
Make certain proper attic ventilation of approximately 1 sq.ft.
Warranty that soffit vents are not blocked by insulation. Make use of 1/4inch plywood or paneling to produce barriers in between the rafters if blown-in insulation tends to roam into the eaves. Pre-fabricated barriers are similarly easily offered.
4. In new homes, roofing felt is utilized from the edge of the roof to a point not less than 12″ inside the inner face of the outdoors wall. In some locations this eaves defense requirements to go 10 or 12 feet up the roof (especially on low-sloped roofs) and the total length of valleys.
5. Try roof heating unit cable as an interim treatment, up till it’s time for new roofing items. Do not forget to point out the problem areas to your roofer, so he can provide enough security items.
A recommendations: Roofing is a clearly “easy enough” job for any person, nevertheless there are many terrific points that may escape the do-it-yourselfer. A specialist roofer can be your pal!
