Ice dams and your homeowners policy: what is covered in a Maine winter

Every February our phones start ringing with the same story. A week of single-digit nights, a thaw on Tuesday, and by Thursday there is a brown stain spreading across a bedroom ceiling. The cause is almost always an ice dam, and the first question is always the same: is this covered?

The short answer is that most homeowners policies cover the sudden water damage inside the house, but not the ice on the roof or the wear that let it happen. The longer answer is worth understanding before the next cold snap, because a few inexpensive steps can keep you from filing a claim at all.

How an ice dam forms

Heat escaping from the living space warms the underside of the roof. Snow on the upper roof melts, runs down the shingles and refreezes when it reaches the cold eaves that overhang the exterior walls. Over days, that refrozen water builds into a ridge of ice. New meltwater pools behind the ridge, finds its way under the shingles and drips into the attic, the walls and eventually your ceiling.

Older Maine homes are especially prone to ice dams. Capes with knee walls, houses with recessed lights in top-floor ceilings and homes with little attic insulation lose a lot of heat right where it causes the most trouble.

What your policy usually covers

Standard homeowners forms cover sudden and accidental direct physical loss unless it is specifically excluded. Water that leaks into the home because of an ice dam is generally treated as a covered loss. That typically includes:

• Damaged drywall, plaster, ceilings and insulation inside the home
• Flooring, trim and paint that must be replaced because of the water
• Personal property such as furniture, rugs and electronics damaged by the leak
• Additional living expenses if part of the home becomes unlivable during repairs

Your deductible applies, and some carriers apply a separate water damage deductible. It is worth checking your declarations page now rather than in the middle of a claim.

What is usually not covered

Insurance pays for sudden damage, not maintenance. Most policies will not pay to remove the ice dam itself or to shovel the roof. If the roof was already failing from age, the cost to replace worn shingles is usually excluded even if the water damage inside is covered. Mold that develops because a leak was ignored for weeks can also be limited or excluded.

The fastest way to protect a claim is to act quickly. Take photos, move belongings, and call us the day you see a stain, not the week after.

Five ways to prevent ice dams

1. Rake the lower roof after heavy snow

A long-handled roof rake used from the ground removes the first three to four feet of snow at the eaves, which is where dams form. Never climb onto an icy roof.

2. Seal attic air leaks

Gaps around chimneys, plumbing vents, attic hatches and recessed lights let warm air reach the roof deck. Sealing them is often cheaper and more effective than adding insulation alone.

3. Add insulation and ventilation

A cold, well-ventilated attic keeps the roof deck close to outdoor temperature so snow melts evenly. Efficiency Maine offers rebates on air sealing and insulation for many homeowners.

4. Keep gutters and downspouts clear

Clogged gutters freeze solid and give ice dams a head start. Clean them in late fall after the leaves drop.

5. Ask about heat cables with caution

Heat cables can help in trouble spots but do not fix the underlying heat loss. Have them installed by a professional and plugged into a protected outlet.

If water is already coming in

Put buckets under active drips, move furniture and rugs, and poke a small hole in a bulging ceiling to let water drain in a controlled way. Photograph everything before you clean up. Keep receipts for tarps, fans and any emergency roof work, since reasonable mitigation costs are often reimbursed. Then call us. We will open the claim, explain your deductible and coverage, and recommend contractors who know how to dry out plaster and old framing properly.

A quick policy check before next winter

Three questions are worth asking your agent in the fall. Is your dwelling limit high enough to rebuild at today's costs? Do you have a separate water damage deductible? And do you carry water backup coverage for the sump pump that works overtime during the spring thaw? If you are a Cedar & Stone client, we review all three at renewal. If you are not, we are happy to look at your current policy with no obligation.
