Every metal roof trim, wall trim and foam closure on a carport, barn, shop or metal building. Click any trim for the full breakdown: drawings, where it goes, how to measure and how to install it.
Ridge Cap
Ridge cap covers the peak where the two roof slopes meet, sealing the panel ends against rain, wind and birds.
Full breakdown →Rake Trim
Rake trim covers the sloped gable edges of a metal roof, sealing the panel edge and finishing the end of the building.
Full breakdown →Eave Trim (Drip Edge)
Eave trim, or drip edge, finishes the low edge of a metal roof where water runs off and covers the eave framing.
Full breakdown →Outside Corner Trim
Outside corner trim caps the outside corners of metal wall panels, sealing raw edges and giving the walls a clean, square finish.
Full breakdown →Base Trim (Rat Guard)
Base trim runs along the bottom of metal wall panels at the slab, keeping water, rodents and bugs out of the wall.
Full breakdown →J-Trim (J-Channel)
J-trim is a small channel that caps cut panel edges around windows, doors, partial walls and other openings.
Full breakdown →Inside Foam Closure
Inside foam closures fill the gaps under panel ribs at the eave and base, blocking wind, rain, birds and bugs.
Full breakdown →Outside Foam Closure
Outside foam closures sit on top of the panel under ridge cap and flashing, sealing open ribs against rain and pests.
Full breakdown →Inside Corner Trim
Inside corner trim seals the inward-facing corners of metal walls, like where a lean-to wall meets the main building.
Full breakdown →Gutter and Downspout
Gutters catch water at the low edge of a metal roof and downspouts carry it to the ground, away from your slab.
Full breakdown →Head Trim (Header Trim / Drip Cap)
Head trim, also called header trim or drip cap, runs across the top of doors and windows and kicks rain away.
Full breakdown →Jamb Trim
Jamb trim covers the sides of door openings, wrapping the framing and the cut panel edges for a clean, sealed finish.
Full breakdown →High-Side Eave Trim
High-side eave trim caps the top edge of a single-slope roof, sealing the panel ends where the roof is tallest.
Full breakdown →Roof-to-Wall Flashing
Roof-to-wall flashing seals the joint where a metal roof runs into a taller wall, like a lean-to against a shop.
Full breakdown →W Valley
A W valley lines the inside corner where two roof slopes meet, carrying heavy water flow safely down to the eave.
