Hail Damage on a Northridge Roof: Functional, Cosmetic, and the Test Square

Hail verdicts turn on one distinction: functional versus cosmetic. On shingles, functional hail fractures or bruises the mat under the granules, felt as a soft, crushed spot, and it shortens the roof's life whether or not it leaks today. On metal, dents that do not breach seams, fasteners, or coating are usually cosmetic, however dramatic they look from the ladder.

In Northridge, the hail damage guide questions are read against a local fact first: Northridge is a neighborhood of the City of Los Angeles in the San Fernando Valley, first settled as Zelzah and renamed in 1929; it has no city hall of its own, and this site serves its postal footprint, named honestly as such. That fact is what changes the order of the steps below for a Northridge household: what gets documented first, what can wait a day, and which call is the first call. The sequence itself is the standing one for this work; the local detail is what makes it this city's version of it.

Adjusters evaluate hail in test squares: a marked 10 by 10 foot area per slope, hits counted and photographed, with soft metal damage (vents, flashing, gutters) as supporting evidence. A roofer's inspection that follows the same method produces a record your insurer can actually use.

Timing matters twice: policies set windows for reporting storm damage, and bruised mats weather faster after the hit. An inspection within days of a named storm, with dated photos, is the difference between a documented claim and an argument about an old roof.
