comes in! When it comes to Lincoln, NE roofing, we are your experts. Be Cautiousĭepending on the height and pitch of your roof, you might want to avoid any DIY and simply hire a roofing professional. Prevention will be a bit more intensive as you may need to add insulation, seal any airflow leaks, or add vents to keep it cool. This should slowly melt the ice and create a groove for the water to escape without coming back into the house. Solution: If the dam already exists, your best bet is to purchase some calcium chloride and pour it into tube socks or pantyhose, laying them vertically across the dam and hanging slightly over the roof. In addition to having water running back into your house, causing roof leaks, ice dams can also rip of gutters and loosen shingles. Then, this cycle of thaw and re-freeze continues until the ice forms so thick that it causes water to dam and run backward underneath shingles. This occurs on the cool part of the eave or the non-heated surface of the roof. Ice dams are formed when the temperature outside warms to above freezing during the day, melting snow, and then re-freezes overnight. Also, make sure the attic is properly ventilated. The pipe should be insulated to keep condensation from forming. Solution: is to make sure that the vents extend through the roof and have a backflow flap. A damp attic combined with poor ventilation can cause mold build-up, which can become a health problem as well. Too much moisture in the attic can cause the roof sheeting to swell and buckle, which is an expensive fix. Bath Vent Transfers Warm, Damp, Heated Air Into The Attic The sealant keeps the water from getting into the wall of the pipe-simple!ģ. Solution: I learned this from a friend of mine that works in heating and cooling, is to remove the cap and seal the top of the double wall pipe with a high-heat silicone or urethane sealant. The water then drips into the attic and onto your ceiling. Usually, this is at a bend, or elbow, in the pipe. The water is trapped within the double wall until it finds an escape. Then, it sometimes runs back into the double-wall pipe. The heated air rises and collects in the cap. Heating or furnace pipes are warm and carry hot, moist air right up through the house. Condensation On Pipes That Vent Through The Attic Stains around vent show where water has been leaking in. The filter blocks the snow but allows the air to flow freely. It can be cut with scissors and friction fit into the bottom of the vent, or if you can, around the upright portion of the vent. The filter is usually blue and about 1″ thick. Hardware stores sell a commercial filter that will come in a roll. Sometimes the water spots will disappear and may be gone for several years until the exact same conditions occur again. The liquid eventually evaporates, sometimes leaving a permanent stain. Now that moisture may start to drip and stain your ceiling. However, when it begins to warm up, and the temperatures get above freezing, the snow is going to begin to melt. This snow piles up, and while it remains cold outside you won’t notice. Roof vents that are designed without filters can end up letting fine, wind-driven snow blow into your attic. The Most Common Causes Of Leaky Roofs In Winter 1. Then, what are these phantom circles? Excellent question. Maybe it was a dry winter, hasn’t snowed much at all. The winter brings us holidays, lights, eggnog, and general good cheer, but unfortunately, it can sometimes cause dark circles to suddenly appear on our ceilings.
