For decades, EDCA Roofing has been safeguarding the homes and businesses of the Emerald City. Established in 1988, our team has experienced Seattle’s varied weather patterns firsthand, understanding the unique challenges and demands they place on residential and commercial roofs. Fall, in particular, brings a set of weather-related concerns that every Seattle property owner should be aware of.

Understanding Seattle’s Fall Weather

Fall in Seattle is notably wet. With the transition from the mild, sunny days of summer to the rainy, cooler climate of fall, the city begins to experience heavier downpours. Often, these rains persist for days, making water drainage a crucial consideration for roofs. Early frosts and occasional windstorms can also threaten ill-prepared or aging roofing systems.

How Seattle’s Fall Weather Affects Different Roofing Types

Low-Slope Applications – Torch Down & Single-Ply Roofs (TPO & PVC):

Torch-down and single-ply roofing systems, like TPO and PVC, are popular for low-slope applications due to their superior water resistance. However, the constant barrage of fall rains can still pose challenges:

  • Pooling Water: Areas that don’t drain well can lead to pooling water, which, if persistent, can deteriorate the membrane and cause leaks over time.
  • Debris Accumulation: Falling leaves and twigs can clog roof drains, exacerbating the pooling water issue.

For these reasons, it’s essential to have routine inspections, especially during the fall, to ensure drains are clear and the membrane remains intact.

Steep-Slope Applications – Composition Shingles:

Composition shingles are commonly chosen for steep-slope roofs, offering aesthetic appeal and durability. However, fall weather can influence their lifespan and efficiency:

  • Wind Damage: Intermittent windstorms can lift or break shingles, exposing the underlayment to leaks.
  • Moss Growth: The moist environment can encourage moss growth on shingles, undermining their efficiency and shortening their lifespan.

Why Professional Installation Matters

While understanding how different roofing types respond to Seattle’s fall weather is crucial, the installation’s quality is paramount. At EDCA Roofing, our highly skilled crews are not only adept in installing torch down, TPO, composition shingles, and PVC roofing systems but also emphasize safety to ensure a top-tier roofing experience.

Proactive Steps for the Fall

Given the challenges posed by Seattle’s fall weather, here are some proactive measures homeowners and business owners can adopt:

  1. Regular Inspections: Before fall, consider getting a professional roof inspection. This can identify potential problem areas, ensuring they’re addressed before they escalate.
  2. Gutter Cleaning: Ensure gutters and downspouts are clear of leaves and debris to facilitate proper water drainage.
  3. Trim Overhanging Branches: Cut back any tree limbs that hang too close to your roof, minimizing the risk of damage during windstorms and reducing leaf accumulation.
  4. Consider Moss Treatments: If moss growth is a concern, consult roofing professionals about treatments or solutions to curb its spread.
