Does a derecho or storm roof claim cover water that came in?
It depends on the policy and on how the water entered. Many homeowner policies respond to wind damage to the roof and to the interior water that follows a wind opening, but the policy wording and the insurer's decision decide the claim. Keep the photographs and records, and ask your insurer what applies.
A wind opening that lets rain in is often treated differently from a leak that has been going on for months. Insurers commonly look at whether the roof was damaged by the storm and whether the water came in through that damage. Photographs of the roof, the opening and the interior are useful.
The Iowa Insurance Division takes complaints about policies issued in Iowa. Its public updates after the 2020 derecho show how large the volume of claims was across the state. A complaint about how a claim was handled can go to the division, while the claim itself is decided under the policy.
Should I tarp the roof myself?
Only if you can do it safely from the ground or a stable ladder, and never on a steep or damaged roof in wind or rain. A roofer should cover and repair the opening. Falls from roofs are serious, and a temporary cover does not replace a repair.
A roof that has been opened by wind is often unstable. Loose shingles, broken decking and wet surfaces make walking on it dangerous. A roofer has the equipment for that work, and it is safer to wait for one.
If you cannot reach a roofer right away, keep the water out of the house in other ways where you can do it safely. Move items, place buckets under drips and keep people away from wet ceilings. Photograph the opening from the ground before any cover is put on.
What should the attic and insulation work include?
The attic is checked for wet insulation, wet framing, staining on the underside of the roof deck and the path of the water. Wet insulation is removed and the framing is dried. The crew reports what it finds, so the roofer and the insurer can see the same condition.
Attic insulation that has soaked up water loses its loft and its insulating value, and it holds moisture against the framing. Removing it is usually the right step once the roof is closed. Drying in place is slow and often ineffective for loose-fill insulation.
The crew checks the framing and the roof deck from inside the attic. Staining on the underside of the deck shows the path of the water, and the readings show where the moisture has reached. These details guide the roofer on which areas to inspect.
- Wet insulation removed and bagged where it cannot be dried
- Framing and roof deck measured for moisture
- Staining on the underside of the deck photographed
- Path of water from the entry point to each ceiling
- Ventilation openings checked for wind or water damage
How do I keep the roof from letting water in next time?
After a storm, have a roofer inspect the shingles, flashing, vents and soffit. Repair loose or missing shingles, reseal flashing and replace damaged vents. A roof that has been opened by wind should be checked again after the next storm, because small damage can grow.
A roof inspection after a storm is a common step homeowners take. The roofer can show where the wind lifted or creased shingles, and can explain the repair. The crew's photographs and the drying record can be given to the roofer as a record of the water path.
Keep the gutters clear and the downspouts directed away from the foundation. Trim trees that drop limbs onto the roof. These are small steps, but they reduce the chance that a future storm opens the roof again.
