When it comes to safeguarding your home from the elements, your roof plays a pivotal role. While shingles often steal the spotlight, two lesser-known components, starter shingles and flashing, work together harmoniously to provide crucial protection against water intrusion. In this article, we'll delve into the world of starter shingles and flashing, exploring their roles and highlighting how their cooperation shields your home from potential water damage.
Understanding Starter Shingles
Starter shingles, often overlooked but highly important, are the first layer of shingles installed along the eaves of your roof. Their primary function is to provide a secure base for the rest of the shingle layers. These starter shingles have a unique design, with a sealant strip that adheres to the row of shingles above them. This sealant creates a watertight barrier, preventing water from infiltrating your roof through the eave edges.
The Role of Flashing
Flashing is another unsung hero in your roofing system. Flashing consists of thin metal strips or sheets, typically made of aluminum, copper, or galvanized steel. These strips are strategically placed in vulnerable areas of your roof, such as roof valleys, chimneys, skylights, vents, and intersections with walls or dormers. Flashing acts as a waterproof barrier that directs water away from these critical junctures.
How Starter Shingles and Flashing Work Together
The synergy between starter shingles and flashing is critical for protecting your home from water intrusion:
1. Eave Protection:
Starter Shingles: As mentioned earlier, starter shingles seal the eave edges, preventing water from seeping beneath the shingle layers. This is vital because water infiltrating the eaves can lead to wood rot, mold growth, and interior water damage.
Flashing: Flashing near the eaves reinforces the water-shedding capability of starter shingles. It ensures that water is directed away from the eaves, reducing the risk of moisture penetration.
2. Valley and Intersection Protection:
Starter Shingles: Starter shingles extend into roof valleys, creating a waterproof barrier in these critical areas. They help prevent water from pooling or seeping through the vulnerable valley joints.
Flashing: In roof valleys, flashing takes the form of "valley flashing" or "valley metal." This metal strip directs water down the valley, away from the roof's interior. Flashing at roof-wall intersections and around chimneys provides similar protection by diverting water away from these potential weak points.
3. Skylights and Vents:
Starter Shingles: Starter shingles extend beneath skylights and vents, ensuring a watertight seal. This prevents water from entering your home through these openings.
Flashing: Flashing is custom-fabricated and installed around skylights and vents, creating a secure barrier against water intrusion. This flashing is crucial to maintaining the integrity of these roof features.
4. Chimneys and Walls:
Starter Shingles: Starter shingles extend up the base of chimneys and walls, sealing these junctures against water infiltration.
Flashing: Flashing at chimney and wall intersections is called "step flashing." It consists of individual L-shaped pieces that are layered with shingles and fitted against the chimney or wall. This technique ensures that water is directed away from these penetrations.
