Leaks and water damage are one of a homeowner’s worst nightmares. No one wants to spend the time and money it costs to fix a leaking roof or deal with the damage a leak can cause to the rest of your home. Roof flashing plays an important, yet often overlooked, role in keeping leaks at bay. Even the best quality roofing may benefit from roof flashing. Roof flashing is made of a thin layer of metal placed around leak-prone areas of the roof, such as where the shingles butt up against the chimney. This prevents leakage at these points that might otherwise slip through shingles alone. Whether you’re a homeowner, property manager, or a DIY enthusiast, understanding the importance of roof flashing can help you avoid costly repairs and extend the life of your roof.
At Custom Contracting, we specialize in providing expert roofing solutions, including roof flashing inspections and installations. Small, preventative steps taken now could save you from major roof repairs in the future. Our experts can evaluate your needs and ensure you have everything you need to keep out the elements.
What Is Roof Flashing and Why Is It Important?
Roof flashing is typically made of aluminum, copper, or galvanized steel and is strategically placed where the shingles of your roof meet any edges, including walls, chimneys, or valleys. These spots are most vulnerable to leaks and water damage. Proper flashing creates a watertight seal along these lines to prevent water from seeping through and accumulating. Even high-quality roofing can succumb to leaks in these spots without the installation of proper flashing. Roof flashing diverts water away from these areas, allowing it to flow off the roof as intended.
Types of Roof Flashing
There are five primary types of roof flashing: step, chimney, valley, vent pipe, and drip edge flashing. Each type serves a different purpose to ensure those particular areas of the roof are protected in the best way possible. Below we break down the various types of flashing and how they can be best utilized:
Step Flashing
Step flashing is installed at the intersection of the roof with any walls of the house. Where the roof and wall meet creates a seam that can allow trickles of water to slip through. A series of overlapping step flashing pieces can direct the water down the seam to the ground instead.
Chimney Flashing
Chimney flashing, as its name suggests, is used where the shingles of the roof butt up against the home’s chimney. Chimneys are a common source of leaks. The flashing is installed around the base of the chimney to ensure a watertight seal that directs the water away from this vulnerable area.
Valley Flashing
Valley flashing protects areas where different slopes of the roof meet. This “valley” is prone to collect standing water. Over time, this water can leak into the roof and cause additional wear and tear on the shingles, increasing the size of the leak. Valley flashing directs water into a runoff to prevent water from pooling.

Vent Pipe Flashing
As with chimney flashing, vent pipe flashing fits around the base of any vent pipes that extend through the roof. Custom fitting the metal to the base of the pipe ensures a snug fit that will prevent any water from leaking in around the edges.
Drip Edge Flashing
Once the water reaches the edges of the roof, there is still a danger of damage. The fascia, the horizontal boards that run along the lower edge of the roof below any gutters, can become damaged over time from constant water runoff. To prevent this damage and ensure water is flowing either into the gutters or directly to the ground, drip edge flashing is installed. It directs water away from the house instead of straight downward, preventing damage to the underlying wood.
How Roof Flashing Prevents Leaks
Roof flashing is your roof’s first line of defense against water infiltration. By sealing joints and directing water away from the weak points, it prevents moisture from penetrating your home’s structure. Flashing works in tandem with shingles, creating a comprehensive waterproofing system. This is especially important during heavy rain or snow when water often accumulates in vulnerable spots.

Signs of Roof Flashing Issues
Knowing when your roof flashing needs attention is key to avoiding leaks and water damage. Here are some common signs of flashing problems:
- Rust or Corrosion: Metal flashing exposed to the elements can rust or corrode, reducing its effectiveness.
- Loose or Missing Flashing: If flashing becomes detached or is pulled off altogether, it will no longer protect the roof against leaks in those areas.
- Water Stains Indoors: Stains on the ceiling or leaks inside your home often indicate compromised flashing in that area.
- Cracks in Sealant: Over time, sealant around flashing can crack, compromising the watertight seal and leading to leaks.
Benefits of Quality Roof Flashing
Investing in high-quality roof flashing has significant advantages for your home:
- Prevents Water Damage: Proper flashing protects your roof, walls, and interior from costly water damage.
- Extends Roof Lifespan: By preventing leaks, flashing helps preserve the structural integrity of your roof.
- Boosts Energy Efficiency: A leak-free roof reduces moisture buildup, improving your home’s insulation.
- Enhances Property Value: A well-maintained roof with effective flashing appeals to potential buyers and boosts your home’s resale value.
