Frozen Pipes and Ice Dams Are Messy. The Estimate Shouldn't Be.
Meltwater backed under the shingles, or a supply line that split in an outside wall. Atlas documents every surface the water passed on the way down, from the roof edge to the floor below.
Ice builds at the cold roof edge, backs water up under the shingles, and drops it into the exterior wall and the ceiling below. A frozen supply line lets go on the thaw, usually while nobody is home, and runs until someone notices. Once the house is dry, Atlas walks it, follows the water from where it came in to everywhere it went, and writes the put-back in Xactimate® from a measured sketch: ceilings, wall finishes, insulation, trim, flooring, and the roof edge, top down and trade by trade.
Roof-edge repair at permit means ice barrier at the eaves to current requirement; insulation that goes back in an opened exterior wall is written to current R-value. Anything over what was there is on its own line as a code upgrade.
Ceilings, the wall below the eave, insulation, trim, flooring, and the roof edge written as one estimate, top down and trade by trade, with the plaster or drywall called correctly and every floor the water reached in the photo report. Measured sketch.
