Much of Waltham's housing predates modern insulation. Pipes in outside walls, over cold basements and under later additions freeze in a hard cold snap and split, and the leak shows up when they thaw.
Ice dams form when heat escaping into the attic melts snow that refreezes at the cold eaves. Meltwater then backs up under the shingles and into the walls and top-floor ceilings. Air sealing and insulation at the attic floor do more than anything else to stop them.
See frozen pipe water damage and ice dam water damage, or the National Weather Service cold safety page.
Winter Pipe and Ice Dam Risk Check questions
Which pipes freeze first?
Pipes in exterior walls, near the sill and rim joist over a cold basement, in a crawl space under an addition, and in unheated porches, garages and attic bathrooms.
Should I let faucets drip?
On the coldest nights a slow drip on faucets served by exposed pipes keeps water moving and relieves pressure, which helps prevent a split.
Does heat tape work?
Listed heat cable can protect a short run of exposed pipe when installed by the instructions. It is not a substitute for insulation or heat in the space.
How do I know if I have an ice dam?
A thick ridge of ice along the eaves with icicles, and stains or drips at the top of outside walls or ceilings during snow melt.
Should I chip the ice off the roof?
No. Chipping damages shingles and is dangerous on a ladder. A roofer can steam it off if needed.
What should I do if a pipe bursts?
Shut the main valve, open faucets to drain the pipe, keep clear of wet outlets and call for extraction.
Pipe split or ceiling dripping?
Freeze and ice dam leaks run inside walls. The response team traces them with thermal imaging and dries them in place.
