Oregon R327 roof-valley flashing metal path
Where locally adopted, Oregon R327 specifies the metal thickness, corrosion resistance, cap sheet, width, and full-valley extent for valley flashing.
A flashing product can document the metal portion only. The minimum 36-inch cap sheet, full-length installation, compatibility, and project details remain separate checks.
Published requirement text
“the flashing shall be not less than 0.019-inch (0.48 mm) No. 26 gage galvanized sheet corrosion-resistant metal installed over not less than one layer of minimum 72-pound mineral-surfaced nonperforated cap sheet”
