Ice Damming
Ice dams are the accumulation of ice at the eaves and valleys of roofs, and in some winter establish considerable problems. Insufficient attic insulation or attic ventilation can set off 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 sets off water to swimming pool behind this dam and frequently the water penetrates in between the shingle layers, dampening the roof deck and possibly the ceilings and walls noted below.
Interior damage set off by ice dam. What To Do?
1. Completely seal all ceiling penetrations such as light to keep warm, damp air out of the attic.
Make certain proper attic ventilation of around 1 sq.ft.
Assurance that soffit vents are not blocked by insulation. Make use of 1/4inch plywood or paneling to establish barriers in between the rafters if blown-in insulation tends to roam into the eaves. Pre-fabricated barriers are also 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 needs to go 10 or 12 feet up the roof (especially on low-sloped roofs) and the total length of valleys.
5. Try roof heating system cable as an interim action, up till it’s time for new roofing items. Do not forget to discuss the concern places to your roofer, so he can provide proper defense items.
