The roofing system is composed of several components and made from different materials. Along with shingles and gutters, the roof flashing plays an essential role in keeping your roof and home free of water damage. But what is it exactly? To help you understand what roof flashing is, metal roofing contractor Hinkle Roofing shares important points to consider.
What Is Roof Flashing?
Flashing is a thin strip of material, usually made from galvanized steel, that protects the roofing system. It secures joints in your roof and is installed in areas that receive a lot of water. With adequate flashing, water will be successfully delivered into gutters; without it, water leaks will definitely start appearing in vulnerable areas of the roof.
What Areas Need Flashing?
Roof flashing is installed in areas where there are joints or penetration.
1. Valleys – The space where two slopes of the roof meet is called a valley. The two slopes both direct rainwater into the valley, making it a vulnerable area for moisture-related issues. To protect the valley, a residential roofing company will typically install a flashing made from long pieces of sheet metal.
2. Chimneys – As for the chimney, a special type of flashing system is required since it’s one of the most important penetrations in a roof. Three types of flashing are installed around a chimney. They are called step flashing (on the sides), apron (below) and cricket (above).
3. Skylights – A skylight is a roof structure installed to increase daylighting. It generally requires a tight seal with the roof. A continuous piece of sheet metal flashing is installed on each side of the skylight.
4. Dormers – A dormer is both a joint and a meeting between two slopes. Similarly in a valley, a length of sheet metal protects the seam between the roof of the dormer and the rest of the roof.
