Roofing in Irwindale is a matter of the city's Building and Safety office, the state energy test and the roof's own layers. We plan replacements, reroofs and new roofs here in climate zone 9, with each scope written layer by layer.

Irwindale's housing, in numbers
ACS 2020-2024 gives Irwindale a median year built of 1985 and about 296 owner-occupied single-family homes (U.S. Census Bureau). That is a small residential base, and a roof there is planned from its own facts.
The question for each roof is how the covering and the layers beneath have worn.
Climate zone 9 in Irwindale
Irwindale sits in climate zone 9 (California Energy Commission zone list). Above 50 percent of a single-family roof, the state cool roof test applies, and overlays count as replacement (California Energy Commission, 2022 Standards).
The numbers differ by slope: SRI 16 is one route on a steep roof, SRI 75 on a low one.
