If you’re an owner of a commercial property, roof flashings are something that may not cross your mind often. However, they play an essential role in the roof and building’s overall structure and safety. There are many types of roof flashings and flashing materials on the market today for various applications. Here are some key things every commercial building owner should know about roof flashing in detail.
What is Flashing on a Roof?
What is commercial roof flashing made of?
Types of Commercial Roof Flashings
Ridge Flashing
Corner Flashing
Corner flashing is put on the outside end of the roof, where it meets an outer wall. It keeps water from getting into the space between the roof and walls.
The flashing is made of sheet metal, bent at a 90 degrees angle, with one edge overlapping the other. The other edge is bent up to rest on the wall and prevent water from getting in.
Corner flashing can be made out of aluminum which is better than galvanized steel because they are lighter and last longer. To flash a corner that has wider walls, you have to overlap two pieces of corner flashing.
Inverted Corner Flashing
Inverted flashing is used at corners where a wall meets a roof. It’s used to seal the gap between the structure and the wall.
Eaves Roof Flashing
Eaves flashing is a type of metal flashing that creates a water seal and protects the framing of a roof from moisture.
There are several different types of eaves flashing available. Metal drip edge is a common form of eaves flashing that helps prevent water from dripping behind a commercial roofing system along with the fascia board of a wall. This type of flashing is often found on wood shake roofs.
Saddle Roof Flashing
Saddle flashing is installed for beams piercing external walls, railing attachment and cantilevered joists. Saddle flashing protects against water penetration from snowmelt and ice dams. Some saddle flashing designs also protect against wind-driven rain penetration. Saddle flashing can also prevent rainwater from pooling in a valley or venting into a roof structure, which can cause leaks.
Vent Pipe Flashing
Vent pipe flashing is a ring of metal with an opening to allow the vent pipe to pass through it. The flashing is placed around the vent pipe so that water cannot get between the pipe and the roof. It is made of metal, with a small sheet metal bent into a half-circle or “U” shape, then attached to the roof.
Why do you need flashing for your commercial building’s roof?
Weather Protection
Flashing is an essential component that prevents damage to your roof from rain and wind. Without it, you’re putting yourself at risk for leaks during winter when the temperature drops below freezing point or summertime heat waves which can lead to further expenses.
Increased Property Value
Water damage can ruin any building, but it’s especially bad for structures that are used in commercial settings. The fear of having their business disrupted by water-soaked carpets or ceilings can take potential clients away. With roof flashing, you are adding protection to your roof against leaking. So you can price your property higher for a greater property value.
Appealing Roof
Flashing makes your commercial building’s roof look polished and aesthetically appealing. Adding flashing to the roofs of buildings is an effective, affordable way of making them more visually pleasing for clients and customers.
