How Roof Flashing Works

Shingles and roof tiles get a lot of attention. That might be because they make up most the visible surface of your roof. However, other less noticeable parts are just as important. Roof flashing is critical when it comes to keeping out water. If it becomes damaged or it’s not installed right, your roof might leak. It takes a roofing expert to replace or repair flashing, but we think it’s important for all our customers to understand key components of their roofing system. This article answers some of the roof flashing questions customers ask most often.

What is Roof Flashing?

Everywhere on your roof there’s a valley or corner, there should also be flashing. Asphalt shingles, slate, clay tile or other roofing materials cover broad, flat surfaces, but anywhere angles come together, roofing experts install flashing. Most commonly, you’ll find it in these areas:

  • Skylight perimeters
  • Around chimneys
  • Along roof valleys
  • Along rakes and eves
  • In joints between vertical walls and sloped roof surfaces
  • Over vent pipes

Sometimes roof flashing is made of plastic, roofing felt or rubber. More commonly it’s made of metal like galvanized steel, aluminum or copper.

What are Common Roof Flashing Problems?

Roof flashing is made of durable material, but that doesn’t mean it’s indestructible. Most of the problems happen when flashing isn’t correctly installed in the first place. Skylights are the most prone to leaks after improper installation. Flashing also sometimes corrodes with age.

Even if they’re made of steel, that metal is thin. It can crack or be torn loose by the elements. Animals can puncture it, or it might become damaged when someone walks across your roof and steps in the wrong place.

They’re placed in areas where heavy water flows, so they work hard every time it rains. When flashing fails, your home could experience leaks around the chimney, skylight, valleys or anywhere else.

How Do You Fix Roof Flashing?

If your roof leak is because of improperly installed or damaged flashing, call Advantage Roofing. It’s not a DIY job because poorly repaired flashing can be just as bad as material that’s installed wrong in the first place. You need the right nails, tools, laps and sealant. It’s not worth spending your weekend and risking your life on slippery roof surfaces for a job that might just start leaking again later. Plus, new flashing doesn’t always match the rest of your roof, and our experts can help it blend.
