Attic Condensation & Ice Dam Leaks

February 10, 2011

Preventing Ice Dam Leaks

Attic condensation and ice damming are related. Both can be caused by warm, moist air leaving the house and entering the attic. Attics will be in good shape if there are no holes, air leaks, or bypasses from the house to the attic and there is sufficient insulation to keep house heat from escaping. If you can ensure good air sealing and insulation, the attic will remain cool and dry, as if it were outside. For example, it is rare to see moisture problems or ice damming on the roof of a detached garage or unheated barn.

Formation Of An Ice Dam

Where to look for leaks

  • around plumbing stacks or plumbing walls
  • chimneys through the attic
  • any light fixtures from the ceiling below
  • electric wiring
  • ducting for fans or heating systems
  • perimeter walls
  • partition walls
  • party walls
  • above pocket doors
  • above lowered ceilings
  • where the side of a cathedral ceiling meets an open attic
  • split level discontinuities
  • where additions meet an older section of the house
  • above rounded corners or staircases
  • balloon frame walls

Prevent Ice Dams With Ventilation

Attic Venting

If you have properly sealed the attic you should not need more attic ventilation. Attic ventilation is overrated. In winter, the cold outside air cannot hold much humidity or carry moisture away from the attic. In summer, attic temperatures are more affected by the sun and shingle color than by the amount of ventilation.

Ice Damming

Ice dams are the large mass of ice that collects on the lower edge of the roof or in the gutters. As more melting snow (or rain) runs down the roof, it meets this mass of ice and backs up, sometimes under the shingles and into the attic or the house.

Ice damming usually occurs with a significant depth of snow on the roof. If the attic temperature is above freezing, it warms the roof sheathing which melts the snow lying on the shingles. This water runs down the roof until it meets the roof overhang, which is not warmed by the attic and will be at the temperature of the surrounding air. If the air and the overhang are below freezing, then the water will freeze on the roof surface and start the ice dam.

The balance between removing ice and damaging the roof

Thick ice is hard to remove. You must decide if trying to remove it will cause more damage than leaving it on the roof. Tools, such as hammers, shovels, scrapers, chain saws, and devices such as shoes with ice spikes can damage roofing materials or the structure below. Chemical de-icers can discolor shingles, break down membranes and corrode flashings and drains. De-icers can also damage plants on the ground.

If damage has occurred and ice must be removed, hiring professionals that use steamers is strongly recommended.

Roof Damage from Ice Dams this Winter

Winter Roof Damage

Ice dams in the Minneapolis – St. Paul area of Minnesota can be nightmares, potentially costing you thousands.

Minnesota winters are hard on our homes. Ice dams are created by a number of factors, most importantly the damage they cause can be significant; water leaks, ice buildup, shingle damage, gutter damage and even structural damage or failure.

The severe weather this winter is not only a headache for commuters but it can also be a huge hassle and hazard for Minnesota homeowners. If you have long icicles hanging from your gutters, that’s a warning sign of possible ice dams on your roof which could lead to major damage to your home.

If you see a buildup of ice and an accumulation of icicles, you need to have a roofing contractor or gutter cleaning company come out and check it out. If left unattended, it can be quite expensive to fix.

  1. Call a professional: Removing an ice dam can be quite dangerous. A good place to start is with a reputable roofing contractor. Check and get estimates and references from contractors in your area. Gutter cleaning companies may also offer this service.
  2. Remove snow from the roof: If you’re tackling the job yourself, there is a special tool for removing snow called a “roof rake”. Carefully pull it down the slope of the roofline. Never pull snow across the roof. You could damage the shingles.
  3. Chip away at the ice: For immediate action, you can chip away through the ice dam so the water can flow through. Stop when you get close to the roofing.
  4. Properly ventilate and insulate the attic: The main cause of ice dams is an overly warm attic.
  5. Never walk on a snow-covered roof: Make sure you work from a ladder to access/fix the damage.
  6. Do not install mechanical equipment or water heaters in attics: These are a fire hazard. Stick to insulation to help keep heat in your home.
  7. Do not use salt or calcium chloride to melt snow off the roof: These chemicals are very corrosive. The runoff of these chemicals can also damage grass and plants.
