Flashing Over Bay Window With Siding

So and there s water damage on the inside on the top of the bay window.

Flashing over bay window with siding.

At the top tuck metal drip cap flashing under the siding and on top of the second layer of wrap. Window flashing is installed at the same time as the window unit. If your home is brick we do a full examination of the caulk around the bay window edge. The first half of window flashing occurs when you or your builder preps the rough opening for the window s installation.

Apply silicone caulking to the backsides of the flashing and place it so that the vertical section covers the overhang of the lip of the roof while the horizontal section lays flat on the roof. Apply a bead of caulk to the felt and set the window in the caulk. Where the center part of the roof of the bay is hitting the siding there s flashing going up under the siding and there s flashing coming down on top of the shingles. Typically flashing a window is a two part process.

First we take measurements of every angle we need we then cut and bend the metal for your new flashing next we use a grinder to cut a small gap into the mortar which allows us to tuck the counter flashing right inside. Nail it in place. Install your drip flashing around the eaves of the bay window roof. We also check for missing flashing cracking in your siding and test the soundness of the windows themselves.

The second half of window flashing occurs once the window unit is secured and squared within the rough. On the side on either side of the hips the flashing actually goes under the shingles and behind the siding. The counter flashing is then. Next comes another layer of building wrap installed like the first layer.

Install the trim just under the drip cap.
