Red Metal Chimney Flashing

Here’s a closeup of a red metal roof with metal chimney flashing.

Roof flashing is an integral part of your roofing that can protect run-off areas or where two opposing surfaces meet from water leaks and damages associated with it. Roof flashing can often be formed to fit the flashing protective purpose and area of your roof and in some cases may even be soldered into different shapes.

Over time, flashing can become loose, rust or deteriorate from inclement weather and time so it is important to check your roof in case of any roof flashing repairs. There are several different types of roof flashing materials that can be chosen for your roof flashing installations that differ in durability and longevity. Depending on the area of your roof, there are different types and techniques of laying flashing that is used to best optimize roof protection. If your roof is leaking or has water damages, there are several signs to keep into mind that can let you know if roof flashing repair is needed.

Roof Flashing Materials

Roof flashing materials can be fabricated with or without rust-resistant metals. Metals without rust resistance include fabricating with plastic, roofing felt or rubber. Materials that do have rust-resistance include galvanized steel, aluminum, and copper. Steel is the most common type of flashing and lowest in cost. Aluminum is usually used in specialized cases and the material is bendy so it is popular as a DIY. Lastly, copper is used in specialized cases and custom fabricated with copper roofs.

Roof Flashing Types:

Chimney roof flashing incorporates flashing that is applied in several areas around the chimney: Saddle flashing for the top of the chimney, continuous flashing around the base, step flashing for the sides, and cap flashing for the upper most edges.

Cricket or saddle flashing is often used on chimney sides that are 30 inches wide or more It’s applied on joists, parapets or other members that protrude over the cladding of the roof in a cavity situation or direct fix. Continuous flashing is used to protect the joints where a vertical wall and slope connect which creates a seamless flow. Step flashing in turns uses a series of right-angled pieces sectioned into shingles where each section overlaps the other and are placed in steps up the roof in order to protect areas where the roof meets the side walls. This can be seen with chimneys, dormers, and skylights.

Chimneys use cap flashing which use mortar or caulk that laps over the top edges of the other flashing in order to prevent water running from behind them. Dormer flashing is applied in several areas around a dormer from the side (step flashing) and base (continuous flashing) or bottom (skirt flashing.) Finally, skylights tend to have their own flashing that is integrated with it, if not then flashing is added on the top, base, and sides.

Here are other flashings types to keep in mind as well, drip edge flashing has an outward projecting lower edge with the intent to guide water flow. It’s applied over roofing felt along rakes and under roofing felt along eaves that prevent water from under roofing along these areas. Diverter or kick-out flashing protects against water going through the build up on the envelope of the roof by diverting water away from the cladding (layer of material that makes the external roof surface) and into the gutter. Skirt flashing is a large single piece of flashing usually found at the bottom of dormers or additions. Valley flashing is a W shaped channel that is placed where two roofs meet usually before the roof’s finishing material is installed. Vent pipe flashing is a cone-shaped and works over the shingles with a flange at the bottom which is worked into the shingles and placed over flues and pipe.

Signs of Roof Leaks:

When a roof is susceptible to leaking, there are tell-tale signs that you may need roof flashing repair or new roof flashing installation. Signs can include damaged or curled shingles, cracks in shingles or dormer walls, holes or penetrations on the roof, water stains, black marks, mold, cracked housing on plastic roof vents or broken seams on metal roof vents.
