Properly installed and high-quality roof flashings are critical to the longevity and effectiveness of your asphalt shingle roof. Flashings serve as a protective barrier, sealing vulnerable areas such as joints, edges, and penetrations. At SkyRight, Sandpoint, ID’s leading roofing experts, we ensure your flashings are installed to the highest standards for optimal performance.
What Are Roof Flashings?
Roof flashings refer to metal components installed to direct water away from critical areas of the roof. Key types include:
- Pipe Flashings: Seal around pipes and vents.
- Valley Metal: Reinforces roof valleys.
- Drip Metal: Protects roof edges.
- Step Flashings: Shields roof-to-wall intersections.
- Apron Flashings: Secures the roof’s top-wall intersection.
- Counter-Flashings: Safeguards chimneys and other structures.
Did you know? Improperly installed or degraded flashings account for over 75% of roof leaks.
Key Flashings for Asphalt Shingle Roofs
1. Pipe Flashings
Pipe flashings seal roof penetrations like bathroom vents. Opt for all-metal flashings over traditional rubber-sealed types, as rubber deteriorates under UV exposure. Painted metal flashings are durable and blend well with your roof’s appearance.
2. Valley Metal
Roof valleys handle concentrated water flow and are highly susceptible to leaks. Choose between:
- Concealed Valley Metal: Suitable for lightweight shingles.
- Exposed Valley Metal: Best for heavy shingles; should be painted to match the roof.
3. Drip Metal
Drip metal prevents water from seeping behind gutters and damaging fascia boards. Ensure:
- Metal extends at least 2 inches onto the roof deck.
- Ice and water shield layers are properly installed over the eave drip metal and beneath rake drip metal for optimal protection.
4. Step Flashings
Step flashings secure the intersection between walls and the roof. Each piece should overlap individual shingles, creating a “step” effect. Ensure the flashings meet or exceed code standards, such as a minimum size of 2 inches up the wall and 3 inches across the deck.
5. Apron Flashings
These protect roof-to-wall intersections, often at the roof’s top. Installed with roofing cement and fastened using color-matched screws, apron flashings prevent water infiltration.
6. Counter-Flashings
Counter-flashings complement step and apron flashings, protecting chimneys and other vertical structures. Replace old or damaged counter-flashings with solid metal pieces that extend over the entire chimney for superior protection.
Choosing the Right Flashings for Your Roof
- Material Durability: Use high-quality metal options for all flashings to ensure longevity.
- Professional Installation: Poor installation can lead to leaks and structural damage.
- Compatibility with Roof Design: Tailor flashings to your roof’s specific needs, such as concealed or exposed valley metal.
