When Hail and Flash Flooding Hit the Same Castle Rock Storm

Two kinds of damage from one cell

Castle Rock sits on the Palmer Divide, the high ground between the Denver and Colorado Springs areas, and summer thunderstorms build over it regularly. A strong cell can start with hail that strips leaves, clogs gutters and dents roofing, then switch to a downpour heavy enough to send water across yards. The hail that piles up in gutters and downspouts can make the flooding worse by blocking the drainage that would normally carry roof water away from the foundation.

After the storm, homeowners often find several problems at once: damaged shingles or siding, water stains on an upstairs ceiling, a soaked lower level, and mud on the patio. These need to be separated. Water that came through a damaged roof is usually treated as storm damage under a homeowners policy. Water that entered from the ground surface is usually treated as flood, which standard homeowners policies typically exclude. Policies differ, so read yours and ask your agent, but expect the insurer to ask how the water got in.

Repairs also have a sequence. A roof that is leaking needs temporary protection before interior drying makes sense, and a basement full of contaminated water needs extraction and removal of wet materials before anyone worries about replacing shingles.

Sorting what happened

Walk the house top to bottom and match each wet area to its source.

IfCeiling stains or drips on an upper floorLikely roof or flashing damage. Arrange temporary covering, then document for the homeowners claim.
IfWater along the base of lower-level walls with a silt lineLikely overland flooding. Treat as contaminated and document for a flood claim if you carry flood coverage.
IfWater pouring from a window wellCould be runoff, a clogged well drain, or overflowing gutters dumping into the well. Note which, because it affects coverage.
IfWater near a downspout that dumps next to the foundationClogged gutters likely played a role. Photograph the hail packed in the gutter before clearing it.
IfWater in both placesKeep separate photo sets and notes for each area so the adjusters can follow the timeline.

Do these in the first day

Photograph hail on the ground with a coin or ruler for scale before it melts.
Photograph gutters and downspouts packed with hail and leaves.
Note the time the storm started and when you first saw water inside.
Cover any roof openings with a tarp only if you can do so safely, or wait for a roofer.
Start removing floodwater and wet materials from the lower level; it will not wait for the roof.
Call your insurance agent and ask whether the roof and the basement will be separate claims.

Questions for your insurance agent

Does my homeowners policy treat water through a hail-damaged roof differently from surface water at the foundation?
Do I have flood coverage, and if so, does it include contents in the basement?
Will there be one deductible or two if the damage falls under different coverages?
Should I wait for an adjuster before removing wet drywall, or can I proceed with photos?
