Oklahomans usually associate ice damage with frozen pipes, but ice dams cause some of the most expensive winter claims we see. They form on the roof edge, force water back up under shingles, and dump it into ceilings and walls. Once it starts, you typically have hours, not days.
What Is an Ice Dam?
When attic heat melts snow on the upper roof, the meltwater runs down to the cold eaves and refreezes. The growing ridge of ice traps the next round of meltwater, which then has nowhere to go but sideways, under shingles and into your home.
Warning Signs You Already Have One
- Large icicles hanging from the eaves
- Ice on the gutters thick enough to deform them
- Water stains on ceilings near exterior walls
- Wet attic insulation
- Peeling paint or bubbled drywall on top-floor walls
If you see ceiling stains during or after an ice event, call us immediately. Our ceiling water damage guide covers what to do first.
5 Prevention Strategies
1. Increase Attic Insulation
R-49 or higher prevents the heat loss that melts snow on the roof. Many older Oklahoma homes have R-19 or less.
2. Improve Attic Ventilation
Soffit and ridge vents keep the attic close to outdoor temperature so snow does not melt unevenly.
3. Seal Air Leaks
Recessed lights, attic hatches, and bath fans push warm air into the attic. Seal them.
4. Install Ice and Water Shield
Self-sealing membrane installed under the first 3 feet of shingles is required by Oklahoma code on new roofs in many municipalities. Older roofs may not have it.
5. Use Heat Cables on Vulnerable Eaves
Self-regulating heat cable along the eaves and into the gutters prevents dam formation in problem areas.
What to Do When Water Starts Coming In
- Move belongings out of the affected area
- Place buckets and towels to contain water
- If safe, gently knock down icicles from the ground (never with a ladder on ice)
- Call a 24/7 restoration company for water extraction and drying
- Document everything for insurance, see our claim tips
