The Impact of Rain on Commercial Roofs

Seattle averages about 38 inches of rainfall annually, with the majority falling between October and May. This constant exposure to moisture can lead to several issues for commercial roofs:

• Water Damage: Persistent rain can penetrate even the smallest vulnerabilities in roofing materials. Once water seeps in, it can cause damage to the roof deck, insulation, and even the building's interior.
• Mold and Mildew: The damp environment created by Seattle's rain is ideal for mold and mildew growth. These can weaken roofing materials and pose health risks to building occupants.
• Leaks: Over time, continuous rain can exacerbate small leaks, leading to significant water damage and costly repairs.

The Challenge of Snow and Ice

While Seattle doesn't experience heavy snowfall compared to other regions, it does get occasional snow and ice. These winter conditions can affect commercial roofs in several ways:

• Ice Dams: When snow melts and refreezes, it can create ice dams at the edges of the roof. These dams prevent proper drainage, leading to water buildup and potential leaks.
• Weight Stress: Accumulated snow and ice add extra weight to the roof, which can strain the structural integrity, especially if the roof isn't designed to handle it.
• Freeze-Thaw Cycles: Repeated freezing and thawing can cause roofing materials to expand and contract, leading to cracks and other forms of damage.

Wind and Storm Damage

Seattle's coastal location makes it susceptible to strong winds and occasional storms, which can impact commercial roofing:

• Wind Uplift: Strong winds can lift and dislodge roofing materials, creating openings for water infiltration.
• Debris Impact: Storms can carry debris that may hit and damage the roof, leading to punctures or tears in the roofing membrane.
• Wear and Tear: Constant exposure to wind can accelerate the wear and tear on roofing materials, reducing their lifespan.

The Role of UV Exposure

Though Seattle is known for its cloudy weather, it still receives enough sunlight to affect roofing materials. UV rays can cause:

• Material Degradation: Prolonged UV exposure can break down roofing materials, making them brittle and more susceptible to damage.
• Thermal Expansion: UV rays can cause roofing materials to expand and contract, leading to cracks and splits.
