Basic flashing profile identification · Lesson 4 of 4

Basic flashing profile identification: defects, verification and case study

The identification mistakes that send the wrong piece to the shop, their corrections, a read-back checklist, a hypothetical counter case and the roof-edge fall protection boundary.

You will be able to: Diagnose the common identification defects, from a wrong variant to a template taken as a drawing, explain how each is corrected and document a case with evidence for review.

Defect: the wrong variant

Counter Flashing 1 and 2 are both four-leg shapes with 7 in of legs in total, but 2 adds an open hem and its last two legs differ by 0.125 in each.

An order that says only "counter flashing" leaves the shop to guess: the girth differs by 1.4375 in.

Fix: name the variant and record the hem end, type, return and gap.

Wrong and right ways to identify a profileFour panels. First, a piece with 4 legs and 4.25 inch girth: calling it Fascia Flashing is wrong, Drip Edge is right. Second, Counter Flashing with no variant is wrong, Counter Flashing 2 with an open hem is right. Third, a hem whose face is not recorded is wrong, and recording the outside face is right. Fourth, the A, D and F style gutters share a 16.125 inch girth and are told apart by their bends.Wrong and right identificationFour traps, each from the library shapesThe piece has 4 legs and a 4.25 in girthWrongCalled Fascia Flashing:3 legs, same girthRightDrip Edge: 4 legs,3 bends, no hemA drawing says "counter flashing"WrongNo variant named:a hem may be missingRightCounter Flashing 2:open hem on leg DThe piece being copied has its hem onthe outsideWrongFace not recorded:default is insideRightFace recorded:outside, as the piece isThree gutters, one 16.125 in girthRead the bends, not the girthA Style, 5 insquare boxD Style, 6 intwo 45° bendsF Style, 6 insloped frontAmber rings mark the bends that tell D and Fapart.

Four panels. First, a piece with 4 legs and 4.25 inch girth: calling it Fascia Flashing is wrong, Drip Edge is right. Second, Counter Flashing with no variant is wrong, Counter Flashing 2 with an open hem is right. Third, a hem whose face is not recorded is wrong, and recording the outside face is right. Fourth, the A, D and F style gutters share a 16.125 inch girth and are told apart by their bends.

Each wrong box shows the mistake drawn from a real library shape; the right box shows what to record instead. Amber rings mark the bends that tell the D and F gutters apart.

Glossary

Look-alike
A different library profile with the same girth or a similar silhouette, such as the Drip Edge and Fascia Flashing (both 4.25 in girth) or the A, D and F box gutters.
Read-back
Checking a completed profile ID card against the real piece, line by line, and reading it back to the person who will form it.
Dimensions to confirm
A flag on a library shape whose legs are drawn to a drawing's proportions rather than published numbers, so every leg must be measured.
Low-slope roof work
Roofing activity covered by 29 CFR 1926.501(b)(10) where sides and edges are unprotected 6 feet or more above lower levels.
