La Grange roofs take water two ways. In winter, snow melts over a warm attic, runs to the cold eave, and refreezes into an ice dam that backs melt up under the shingles. In summer, wind-driven storm rain forces its way under shingles and flashing. Either way the water ends up in the attic, the insulation, and the ceilings below. Crews dry the envelope and stop the spread.
How roof water gets in here
- Ice dams at the eaves that push snowmelt back up under the shingles
- Wind-driven rain forced under shingles and around flashing
- Failed flashing at valleys, chimneys, and roof-to-wall joints
- Clogged gutters that let water back up under the roof edge
Once water is inside, it soaks the attic insulation and travels down the rafters to the ceilings, where it shows up as a ceiling stain. The source is the roof, so tracing it right is what stops the repeat.
The roof leak response
- Tarp or stop the active leak where it is safe to do so
- Dry the attic, remove or dry the wet insulation, and dry the framing
- Dry the ceilings and wall cavities the water reached
- Verify a dry reading and coordinate the roof repair, with structural drying throughout

- Air-seal and insulate the attic floor so the roof deck stays cold
- Improve attic ventilation to carry heat and moisture out
- Keep gutters and downspouts clear before winter
- Rake heavy snow off the lower roof after a big storm
Ice dams are an attic problem, not just a roof problem
An ice dam forms because heat escaping into the attic melts the snow, which refreezes at the cold eave. The lasting fix is air-sealing, insulation, and ventilation that keep the roof deck cold, not just chipping ice every winter.
