Building Siding Flashing & Finish Details for Building Corners
Flashing Details for Windows and Doors
If windows and doors are properly protected with splines of felt or flashing tape, there is no need to caulk the joints where siding meets the side casings.
At the top of a door or window, always direct the sheathing wrap over the head flange or cap flashing. Never caulk the joint between the siding and the head casing or the sill, leaving these joints open to drain any trapped water.
Also see WINDOWS & DOORS.
Siding Details At Roof-Wall Joint Step Flashings to Avoid Rot
Stop wood sidings at least 1 inch short of the bottom leg at step flashings and other roof flashings.
Otherwise water will wick up into the flashing leading to paint failures and decay (see Figure 1-6 above left). Our wall siding photo (above right) shows the beginning of deteriorating wood clapboards that were installed touching the surface of an abutting lower asphalt shingle roof.
