3 Tips to Prevent Leaks Due to Freezing Attic Pipes

Frozen Pipe Leak Causing Winter Water Damage

Because water always flows downward, freezing attic pipes that rupture are especially damaging to the living spaces below. In many areas of the country where homes are built on a slab foundation, water supply lines are routinely routed through the attic space. Because most attics are unconditioned, a hard freeze that plunges attic temperatures into the mid-20s for any length of time can cause a burst pipe.

A ¼-inch split in a water line caused by freezing can potentially unleash 600 gallons of water per hour when the pipe thaws. The torrent will quickly permeate through openings in ceilings and soak rooms below. Water will also cascade into the interior of wall cavities and flood deep into the structure.

To avoid drastic consequences—home water damage and inevitable mold contamination—here are three tips to prevent freezing attic pipes.

Insulate exposed pipe. Wherever water supply lines pass through the attic, foam pipe insulation sleeves should be installed on all exposed spans. Simply laying batts of existing fiberglass insulation over the pipes or burying the pipes in loose-fill cellulose insulation is not sufficient. Use foam pipe insulation specifically designed for the purpose. Also make sure all sections of the pipe are insulated"custom cut and form insulation pieces to cover rounded elbows, t-joints and other irregular spans.
Use heat tape on problem pipes. If a span of pipe is particularly vulnerable to low temperatures, electric pipe heating tape acts like an electric blanket for pipes to prevent freezing. Controlled by a thermostat to activate only when the attic temperature plunges dangerously low, the tape typically consumes about 5 watts per foot. Therefore, a six-foot span of “problem pipe” would only use about 30 watts when activated in cold temperatures. Because of potential hazards, pipe heat tape must be installed by a professional plumber or electrician only.
Consider PEX pipe. PEX is flexible cross-linked polyethylene now commonly installed as household water supply lines instead of rigid copper. Though PEX is not entirely resistant to damage if extremely frigid temperatures strike, its flexibility makes it more freeze-tolerant and less likely to rupture during “normal” winter weather.

Taking proactive steps to prevent leaks due to freezing attic pipes is essential for safeguarding your home against the harsh winter conditions. By following these three key tips – proper insulation, maintaining a consistent temperature, and regular inspections – you can significantly reduce the risk of water damage from frozen pipes.
