Venting Options (Balance Intake and Exhaust)

* Ridge + soffit (gable): Soffit vents low for intake, ridge vent high for exhaust.

* High‑wall vent (lean‑to/modern): Intake low at eave, exhaust at the tall wall or ridge line.

* Gable vents: Simple for small sheds without soffits; pair with low intake.

Placement tips

* Keep insulation clear of intake vents.

* Use insect‑screened vents sized per manufacturer.

*Even spacing looks better and works better.

Exterior Trim and Fascia

Check straight lines
Sight sub‑fascia; plane or shim before installing the finish fascia.

Install trim
Casings around doors and windows, corner boards, and skirt/fascia trims per your plan.

Head flashings
Slip head flashings under the WRB head flap and extend past jambs.

Reveal consistency
the Keep equal reveals around openings and at corners; use a spacer block for repeatable gaps.

Weather Details for Doors
Caulking Siding

Seal, Prime, and Paint

Sealants: Use high‑quality exterior sealant where trim meets siding; don’t seal weep paths.

Priming: Prime cut ends and any raw edges before painting.

Paint: Two finish coats per manufacturer; follow dry times and weather windows.

Hardware Tune‑Up

Hinges: Add a long screw at the top hinge into the stud to prevent sag. Tighten all hardware.

Latch/hasp: Align for smooth close; adjust strike/keeper as needed.

Weather strips: Add or replace threshold and jamb seals where appropriate.

Penetrations and Accessories

Lights/vents: Use compatible flashing boots or plates.

Conduit/cable: Seal with exterior‑rated grommets and sealant.

Shelving hooks/ledger strips: Pre‑drill into studs; avoid over‑tightening.
