Roseville Roofing: Article About Understanding Flashing Locations
Homeowners are often concerned about a roof's overall appearance, including the shingles. Although quality roofing materials are critical to the structure's water resistance, flashing is also an important part to service consistently. Flashing is the metal sections found across certain roofing areas. They're usually made out of galvanized steel and even aluminum. When homeowners work with Roseville roofing professionals, they can point out all the required locations for flashing installations.
Roofs aren't featureless surfaces, but have various penetrations across them. Pipes emerging from the interior rooms for ventilation are an example along with chimneys. All these penetrations must be surrounded by flashing. Shingles don't perform well in transition areas, making the roof vulnerable to extensive damage. Flashing is installed around all penetrations and possibly covered by some shingles to create a more aesthetically pleasing appearance.
Skylights are a specialized penetration with an entire frame edge vulnerable to leaks. With flashing screwed to the wood curb and secured with roof cement, skylights can stand the test of time without any major leaks. Roofers simply need to inspect the flashing transition points each year to verify no weathering or loosening has occurred.
Several roof connections exist on every structure, including valleys. A valley is a location where two roof surfaces meet at a low point.

Rainwater usually funnels through this area, making it vulnerable to possible leaks. Flashing is used generously in these areas because it doesn't wear down as much as shingle installations. Roofers will carefully inspect these valley areas for any weak points over the years. Because water consistently moves through this area, any flashing loosening or lifting can allow moisture under the roofing materials.
Dormer windows are those picturesque extensions from a pitched roof, creating a small nook to gaze out into the yard. The dormer's design creates a transition point on the roof, however. Flashing must cover the entire transition seam between the dormer window and roof. Roofers make the installation appear seamless from the ground, but the dormer remains protected against water seeping into the walls or window frame. Flashing may even be located near the dormer window's top edge with the roof to further protect the structure.
Flashing is used for its durability and strength against weathering, but damage can occur over the years. From weather events to rust, flashing must be inspected by roofers along with the shingled surface. Both materials combine to create a strong roof that protects against potential leaks into the interior.
