Eave
The lower edge of a roof that overhangs the exterior wall. Eaves direct water away from the siding and provide shade.

Why Eaves Matter for Insurance Claims
The eave is where many roofing components converge: drip edge, starter strip, gutter, fascia, soffit, and in cold climates, ice and water shield. Storm damage at the eave often affects multiple components simultaneously. Wind uplift is strongest at the eave edge because air pressure differential is greatest there. When inspecting eave damage, document each affected component separately to ensure the estimate captures the full scope of repairs.
Eave Components in Xactimate
Each component at the eave has its own line item in Xactimate. Drip edge and starter strip fall under the RFG roofing category. Fascia and soffit are under exterior trim or siding. Gutters have their own category. When writing the estimate, measure the linear feet of eave perimeter and apply the correct quantities to each component. Bundling eave components into a single line item underestimates the scope and cost of repairs.
Ice Dams and Eave Protection
In cold climates, building codes require ice and water shield membrane from the eave edge to at least 24 inches past the interior wall line. This protects against ice dam leaks, which form when melting snow refreezes at the eave. If an insurance claim involves ice dam damage, the estimate should include ice and water shield as a required component, not just standard underlayment, at the eave area.
Frequently asked questions
The eave area includes drip edge, ice and water shield (in cold climates), starter strip shingles, gutter, fascia, and soffit. Each is a separate line item in Xactimate and should be measured independently.
Eaves are exposed to wind uplift from below, ice dam formation in cold climates, and water runoff from the entire roof surface. The combination of exposure and multiple component intersections makes the eave a common source of leaks and storm damage.
Ice dams form at the eave when heat from the attic melts snow that refreezes at the cold roof edge. The ice backs up water under the shingles, causing leaks. Ice and water shield membrane at the eave helps prevent this type of damage.
