Flashing is thin metal sheets installed under the shingles, at roof/wall intersections, around chimneys and other areas utilized to protect and to redirect water and help keep water intrusion from occurring into your home.
You may have noticed it on the edges of your roof, around your chimney, in your valleys (the area where too roof slopes meet), around vents or skylights.
These areas are very susceptible to water penetration and can result in leaks if they aren’t protected with flashing that has been properly installed.
Water Intrusion (Leaks) can cause real damage.
- Damage to your roof decking and supporting framework,
- Damage to your attic and insulation, your walls and ceilings
- And anything that lies beneath your roof can fall a victim to the dreaded roof leak.
There are several types of flashing and methods of installation, depending upon the areas it will be used.
Some of the most common types are:
Step Flashing – This is the L shaped flashing that is used at the walls following the rake of the roof. It is installed between each shingle.
Counter Flashing – This is installed atop the step flashing where the roof meets brick or stucco surfaces. Oftentimes this counterflashing will be slightly embedded, or cut into the masonry or siding, then sealed for best construction results. The counter flashing covers & protects the open areas above the step flashing pieces.
Apron Flashing – Similar to step flashing as it’s L shaped and used where lateral surfaces meet the roof. Typically the apron flashing is found at the base of a chimney or skylight.
Drip Edge – Installed at the edge of the roof decking and wraps over the facia to protect that roof/fascia intersection. The metal edge/drip edge flashing promotes a clean corner cover underneath the shingles and helps protect both roof deck and fascia trim boards.
Kickout Flashing – This is used where gutters end on a sidewall and helps direct water away from the roof or toward the gutters. More and more we are seeing this repair called out on our real estate customers inspection reports that we help our realtors with.
A small and relatively low cost measure, metal flashing is super important in the quality results of any roof installation and repair. Roofing Solutions can help you know the proper type of flashing and methods of installation required for your roof.
