Drip edge is a fundamental component of a proper roof installation. It protects the fascia, prevents water from wicking under the shingles, and provides a clean, finished edge.
Yet, it is one of the most frequently omitted items on initial insurance estimates.
The most common excuse adjusters use is: "The existing roof didn't have drip edge, so we don't owe to add it now." This argument is fundamentally flawed and easily defeated if you know how to leverage the building code.
The Code Mandate: IRC R905.2.8.5
The International Residential Code (IRC) is adopted by the vast majority of municipalities across the United States. Since the 2012 edition, the IRC has been absolutely unambiguous regarding drip edge.
IRC Section R905.2.8.5 (Drip Edge): "A drip edge shall be provided at eaves and gables of shingle roofs. Adjacent segments of drip edge shall be overlapped not less than 2 inches (51 mm). Drip edges shall extend not less than 1/4 inch (6.4 mm) below the roof sheathing and extend up back onto the roof deck not less than 2 inches (51 mm)."
Notice the word "shall." In building code terminology, "shall" means mandatory. It is not a recommendation; it is a requirement.
Defeating the "It Wasn't There Before" Argument
When an adjuster claims they only owe to replace what was existing, they are ignoring the policy's "Ordinance or Law" coverage.
Almost all modern homeowner policies include Ordinance or Law coverage (often as an endorsement). This coverage specifically pays for the increased costs necessary to comply with current building codes during the repair or replacement of damaged property.
Therefore, even if the 20-year-old roof was installed before the 2012 IRC mandate and lacked drip edge, the new roof must comply with the current code. The carrier is legally obligated to pay for the drip edge to bring the property up to code.
Supplementing for Eaves AND Rakes
Another common carrier tactic is to approve drip edge for the eaves (the horizontal edges) but omit it for the rakes (the sloped gable edges).
Look closely at the code citation above: "A drip edge shall be provided at eaves and gables of shingle roofs."
When supplementing, you must ensure you are requesting both:
You must calculate the total linear footage of the perimeter (eaves + rakes) and ensure the combined quantity of RFG 175 and 176 matches that total.
Don't Forget the Gutters
You cannot properly install drip edge at the eaves if the gutters are tight against the fascia. The gutters must be detached to allow the drip edge to extend down the face of the fascia, and then reset afterward.
Therefore, every time you supplement for drip edge, you must also supplement for GTR D&R (Detach and Reset Gutters).
Automating the Drip Edge Argument
Writing out the IRC citation and explaining Ordinance or Law coverage on every single claim is tedious.
EstimateDelta handles this automatically. If an uploaded estimate is missing RFG 175, RFG 176, or GTR D&R, our engine flags them instantly. The generated Supplement Letter includes the exact IRC R905.2.8.5 citation and the Ordinance or Law justification, ready to be sent to the desk adjuster.
