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 often the water permeates in between the shingle layers, moistening the roof deck and potentially the walls and ceilings listed below.
Interior damage brought on by ice dam. What To Do?
1. Thoroughly seal all ceiling penetrations such as lights to keep warm, wet air out of the attic.
Guarantee appropriate attic ventilation of around 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 develop barriers in between the rafters. Pre-fabricated barriers are likewise readily available.
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 areas this eaves defense should go 10 or 12 feet up the roof (particularly on low-sloped roofs) and the complete length of valleys.
5. Attempt roof heating unit cable televisions as an interim procedure, up until it’s time for brand-new roofing products. Do not forget to mention the issue locations to your roofer, so he can supply sufficient security products.
An advice: Roofing is an obviously “simple sufficient” task for anybody, however there are lots of great points that might get away the do-it-yourselfer. An expert roofer can be your buddy!
