Ice Damming

Ice dams are the build-up of ice at the eaves and valleys of roofs, and in some winter seasons produce significant issues. Inadequate attic insulation or attic ventilation can trigger roof snow to move and melt down to the eaves, where the roof surface area is cooler and the melting snow adheres the roof. Subsequent melting triggers water to swimming pool behind this dam and in some cases the water permeates in between the shingle layers, moistening the roof deck and perhaps the walls and ceilings listed below.
Interior damage triggered by ice dam. What To Do?
1. Thoroughly seal all ceiling penetrations such as lighting fixtures to keep warm, damp air out of the attic.
Guarantee sufficient attic ventilation of roughly 1 sq.ft.
Guarantee that soffit vents are not obstructed by insulation. If blown-in insulation tends to wander into the eaves, utilize 1/4inch plywood or paneling to produce barriers in between the rafters. Pre-fabricated barriers are likewise offered.
4. In brand-new houses, roofing felt is used from the edge of the roof to a point not less than 12″ inside the inner face of the outside wall. In some regions this eaves defense needs to go 10 or 12 feet up the roof (specifically on low-sloped roofs) and the complete length of valleys.
5. Attempt roof heating system cable televisions as an interim procedure, till it’s time for brand-new roofing products. Do not forget to explain the issue locations to your roofer, so he can offer sufficient defense products.
An advice: Roofing is an obviously “simple sufficient” task for anybody, however there are numerous great points that might leave the do-it-yourselfer. An expert roofer can be your friend!
