Pittsburgh Roof Vulnerability
Because there are certain parts of the roof that tend to be more vulnerable to water damage and leaking, flashing can serve as an extra layer of protection. In addition, areas that are particularly susceptible to problems area:
- Skylight Exterior Edges
- Roofing Area Around Dormer Walls
- Roofing Chimneys & Chimney Saddles

Any area of the Pittsburgh roofing system in which two surfaces are coming together to meet, water runoff is likely to be increased, which is why properly installed Pittsburgh roof flasihng is highly important.
Variaties of Roof Flashing
Flashing is typcially not a one type works for every roof type of solution. It is normal for the type to change greatly from one property to anther, depending on style and design of the house. Also, its even possible for it to differ from one area of the roof to another area.
Below are some of the most common types of Pittsburgh roof flashing you could locate on a roofing system:
Continuous flashing: Commonly referred to as “apron flashing”. Installing one long piece of continuous flashing provides protection to the joint between a vertical wall and a sloped roof.
Drip edges: Typcially installed under the Pittsburgh roofing felt along the eaves of a roof. This helps water drip off the roof without damaging the home.
Step flashing: Step flashing is a rectangular piece of flashing bent 90 degrees in the center. Use it for roof to wall flashing. Overlap these flashings to prevent water from getting behind.
Valley flashing: A W-shaped piece of metal flashing. Place this on top of the roofing felt in the areas where two valleys of a roof plane join.
Vent pipe flashing: A cone-shaped fitting. Install pipe flashing into the shingles to cover pipes.
Base flashing: Some roof features, such as chimneys, require different pieces of flashing. This ensures that rain always meets a flashing surface that directs it downwards. The base flashing is continuous roof flashing. Use this as the bottom piece.
Counter-flashing: Placed opposite to base flashing, or above base flashing, counter-flashing completes the two-part team.
Cap flashing: An L shaped structure that lies flat against the roof and other fittings such as windows. The shape of the structure runs water off in the opposite direction. This prevents it from pooling in any cracks around the fitting.
Chimney flashing: Flashings need to be applied around chimneys. This prevents water pooling in the gaps between the roof and the chimney bricks. To begin, apply chimney flashing in two pieces (base and cap). Next, place base flashing across the bottom of the chimney, while using step flashing to cover the sides. Finally, caulk the cap flashing where it laps over the other flashings to prevent water running behind them.
Saddle flashing: Used to cover protruding beams or railing attachments.
Skylight Flashing: Often skylights have a built-in flashing to protect water from seeping in, but sometimes roofing professionals must create it or purchase it separately. First fit continuous flashing along the base
Most Common Areas for Pittsburgh Roof Leaks
Experts agree that the roof areas that have the highest risk for leaks include the valleys and locations where pipes penetrate the roof surface. The best solution to prevent leaks in these areas is to use an asphalt roofing cement to seal and keep out water. Ensuring the pipes have the proper vent pipe flashing is another way to stop leaks in this area of vulnerability.
Damaged flashing poses another risk for Pittsburgh roof leaks. Because it is regularly exposed to the elements, it makes sense that it will experience some wear and tear over time. From cracking and warping to coming loose from the roof, it can have issues that leave your roof unable to do its job to keep your house safe and dry.
