What Is Roof Flashing And Why Is It Necessary

Roof flashing protects your roof from water damage.

Without roof flashing, your house or building is vulnerable to water damage because the water could get under the shingles and into the underlayment. An underlayment protects the roof deck from moisture and serves as backup protection in case the water gets under the shingles.

In the US, most states have a code on roof flashing, but many of them arent overly specific.

Florida Building code gives instructions that are more specific. It requires that roof flashing is installed in all these vulnerable places on your roof, in such a manner as to prevent moisture from entering the wall and roof through joints in copings, at intersections with parapet walls, and other penetrations through the roof pane.

Here are the Florida Building code requirements for the metal flashing material:

If your roof leaks, the chances are pretty good that deteriorating metal roof flashing is the culprit. Flashing protects the intersections between roof planes the joints where roofing meets dormers, skylights, and chimneys and a roofs edges. For a complete discussion of the various types of flashing used on a roof, please see How Roof Flashing Works.

Given enough time, these formed sheet metal angles and troughs can rust, deteriorate, or simply work loose from the surfaces they protect, opening up places for water to penetrate. Because flashing tends to be used where there is heavy water flow, leaking flashing can funnel streams of water into a house.

Check the flashing as well as the condition of your roof shingles. Look carefully for loose nails and holes as well as the seals at the edges of the flashing. Roofing cement and caulking can become dry, cracked, and crumble away, exposing joints to the elements. It is a simple matter to reseal the flashing and much less trouble than patching and painting water-stained walls and ceilings.

New flashing can look conspicuously shiny, so you may want to paint it and touch up existing flashing to blend with the roof. Even galvanized metal flashing corrodes after extended exposure to rain and sun.

How To Install Roof Flashing


Disclaimer:Roof flashing should always be installed by professional roofers, who understand best practices, safety requirements and the building codes and laws in their area. These instructions are only to help homeowners understand what to expect from their roofing professional.

Step flashing is the most time-consuming of all flashing jobs on the roof because you must complete it step-by-step as you shingle up the roof. There are a few general best practices you need to know. First, step flashing must be installed before the siding, so that the siding can cover the top of the flashing. If this is a repair job, the siding must also be removed and replaced with the flashing. Second, step flashing needs to extend 8 to 14 inches above the shingles, according to the National Roofing Contractors Association .

Also, before you start installing your flashing, you need to look to see if the wall in question has a corner on the roof face, as in the image below.

If it does, follow our first installation procedure. If it doesnt have a corner, and simply looks like the image below, follow the second installation procedure.
