Before listing your home for sale, do what this client did and hire a qualified contractor to go through the house repair obvious defects BEFORE you list. In this market, rotted wood and leaks scare buyers. Here, a previous "contractor" caulk the flashing and attempted to paint it grey to match the mortar in the brick. Plus....it all leaked! After scraping out the old caulk, we repainted the flashing with flat black Rustoleum paint and resealed the flashing with Through the Roof....the only clear elastromeric sealant HandyANDY uses to seal roofs and flashing. Great stuff and holds up for many years to UV rays. You can find this a most Ace Hardware stores around the country...if not, ask for it!
