roofing supply company marietta Why Is Roof Flashing Essential?

In order for a roof to do its job, it’s important to keep it well maintained and to watch for any problems. However, even the most impeccably maintained roof won’t stand up to environmental factors if substandard products are used. That’s why it’s essential to use only the best roofing supplies in Marietta and to include all the essential components. Roof flashing is one of these crucial components, so if you don’t know a lot about flashing, here’s what you need to know.


Where Is Flashing Installed?

Roof flashing is basically what’s used in any joints on the roof. It’s installed between two roof sections as well as around the points where a chimney or skylight joins the roof. Hood and pipe vents on the roof also require flashing with the shingles and flashing overlapping. When flashing strips are installed around a chimney, the strips go under the shingles and over the lower section of the chimney. Dormer windows and skylights require flashing between rows of shingles so that the flashing can do its job properly.


What Flashing Does

Flashing helps keep water out of the home. However, flashing plays a special role because other roofing materials are unable to keep water out of areas that are more prone to seepage, like around windows, chimneys, and vents. The flashing is an added layer of protection that’s installed between the exterior roofing material and the waterproof film underneath.


Types of Flashing

Flashing is made of many different types of waterproof material. The common types of roof flashing are valley flashing, drip edge, vent pipe, and step and continuous flashing. A roofing supply company in Marietta may offer flashing made of galvanized steel, rubber, plastic, aluminum, or copper. The material must be not only water-resistant but resistant to corrosion and able to adjust during temperature changes. The type of material used depends on where the flashing is being used as well as the price range people are willing to spend.

Other than lessening the chance of leaks in seams and valley, flashing is important for a number of reasons. It diverts seeping water back out of the roof so that there’s less likelihood of mold growing inside the attic. The flashing membrane discourages insects from penetrating the roof as well. There are aesthetic benefits to flashing because it creates sleek and polished lines around the roof edges.


Signs of Damaged Flashing

It’s important to inspect your roof, including the flashing regularly. Check for small holes in the flashing that may be caused by corrosion or birds. Rust or corrosion will likely occur after time, so if you notice some, be sure to replace the flashing. Missing pieces, cracks, or dents in the flashing also indicates compromised flashing, which means you’re more susceptible to leaks. Any evidence of leaking water like mold, stains, visible leaks, or damaged siding or shingles is also a good indicator that your flashing needs to be replaced.


Replacing Damaged Flashing

If you’ve determined you need to replace the flashing, it’s important to have the right tools and material so that the job is done correctly. It’s a good idea to talk to a roofing supply company to get another opinion on the best type of flashing for the job. You’ll also need to get roofing nails, cement, and tin snips.
