At the eave and the rake, set up U-form drip-side flashing made for reroofing jobs. Install the awning first, then place it on the top. The sections should be correctly assembled in the corners. Nail the extra elements into the roof from below, on the inside of the shingles.


If you’ve got an open valley, set up new W-form steel or vinyl valley flashing to match without delay over the old flashing. Attach it with the aid of using nails into the outdoor edges best. Do now no longer force nails much less than 6 inches from the middle of the flashing.


Use a starter strip or reduce portions for a starter route.

You’ll want to pry the siding outward to slide withinside the flashing; in a few cases, you may just get rid of the siding.


Protect the step flashing with counterflashing. On a chimney, use a grinder to reduce an indentation into the mortar. Cut and bend the counterflashing to in shape snugly into the reduced mortar and to cover at the least three inches of the step flashing. Apply mortar with a caulking gun and flashing should be set into the mortar.
