Custom Flashing, Valleys, Vents & Skylights, part of the whole roofing system
Chimney flashing is a system of strategically placed sheet metal that creates a watertight seal where your chimney meets the roof. Flashing is a crucial part of protecting your home from water damage by preventing leaks at this vulnerable spot.
Components of Chimney Flashing
Base Flashing: These pieces are installed directly on the roof and extend up the sides of the chimney. They are usually integrated with the shingles.
Counter-Flashing: These pieces are embedded into a groove cut into the mortar of the chimney. Counter-flashing sits on top of the base flashing, directing water away from the chimney.
Saddle Flashing: Used for wider chimneys, saddle flashing creates a small, peaked ridge behind the chimney to divert water and snow around it.
Why Chimney Flashing Is Important
Prevents Leaks: The junction between the chimney and roof is particularly prone to leaks. Flashing acts as a barrier, ensuring water flows away from the chimney instead of seeping inside.
Protects Against Rot and Structural Damage: Water leaks around your chimney can cause significant and costly damage to your roofing system, attic and interior walls. Proper flashing is a key preventative measure.
Long-Lasting Protection: Chimney flashing is typically made from durable metals like galvanized steel, aluminum or copper, providing years of protection when correctly installed.
Important Note: Installing chimney flashing requires skill and precision. It’s always best to hire a qualified roofing contractor to ensure the job is done correctly.
Top Layer of Protection: Counter-flashing is a type of flashing usually made from sheet metal (like aluminum, galvanized steel or copper) that provides the final layer of protection where a roof surface meets a vertical element like a wall, chimney or skylight.
Works with Base Flashing: Counter-flashing is installed over the base flashing. Think of it like an extra-waterproof raincoat that fits over your regular coat.
Water Diversion: Its primary function is to direct water away from the point of intersection. The shape of counter-flashing helps guide water down the vertical surface or onto the roof, where it can flow safely away.
Where You’ll Find Counter-Flashing
Chimneys: Counter-flashing is embedded into a groove in the chimney’s masonry.
Walls: Counter-flashing protects the places where rooflines meet exterior walls (headwalls and sidewalls).
Skylights and Other Protrusions: It can be used with other vertical elements that penetrate the roof.
Why Counter-Flashing Is Important
Prevents Leaks: Counter-flashing stops water from sneaking in behind base flashing, which could lead to rot, mold and structural damage.
Increases Longevity of Base Flashing: Because it provides extra protection, counter-flashing helps extend the lifespan of the base flashing beneath it.
Beyond shingles, your roof is made up of several key components. Valleys, where roof planes meet, and vents that allow airflow are crucial for proper water shedding, ventilation and a long-lasting roof. Luc’s Roofing ensures expert valley and roof vent installation and repair for optimal performance.
Why They Matter: Roof valleys channel water down your roof. Properly installed valleys are vital for preventing leaks.

Choosing the right valley material for your roof type
Self-sealed skylights blend effortlessly into a roof, keeping a trim and tidy appearance. One of the key aspects in creating curb appeal for your home is the way all parts of a roof fit together and work in unison.
Installed perfectly, the skylight featured here creates a brighter space illuminated by natural light and looks great.
Why They Matter: Proper ventilation makes your roof function better and last longer. Often the soffit vents are blocked by insulation.
A slant-back ventilation system allows the air to enter from the low end of the roof and exit at the top, keeping your shingles from curling and becoming brittle before their time.
