Local siding experts who know Northwest weather
In Western Washington, your home’s exterior doesn’t just face the rain—it faces persistent moss growth, corrosive salt air, and grueling wet seasons that test the limits of your home's envelope. That’s why Topside Roofing focuses on high-durability materials, precision installation, and long-term maintenance solutions.
We aren't just a roofing company that "also does siding." As a fully licensed and insured siding contractor, we bring decades of local experience and a proven track record to every project. We pride ourselves on clean, efficient job sites and provide photo-documented work so you can see the quality of our craftsmanship behind every board.

Expert Siding Contractor Services:
Full Siding Replacement
As a leading siding contractor, we specialize in complete exterior transformations for homes with aging, cracked, or water-damaged exteriors. Our team handles the entire process: removing old materials, inspecting the underlying sheathing, installing high-performance moisture barriers, and rebuilding your home’s protection from the studs out.
Partial or Targeted Repairs
You don’t always need a full overhaul. If you’re dealing with isolated impact damage, dry rot, or pest issues, our experts provide targeted repairs. We focus on structural integrity and meticulous color-matching to ensure your new siding blends seamlessly with the rest of your home.
Siding Upgrades During Roof Replacement
Maximize your investment by hiring a siding contractor who understands the "whole-home envelope." If we are already replacing your roof, it is the most cost-effective time to address siding transitions, flashing, and trim alignment. This integrated approach ensures a completely weather-tight system from the ridge cap to the foundation.
Trim, Fascia & Soffit Renewal
Protect your eaves and elevate your curb appeal. We refresh your home’s architectural edges with durable new trim and paint-grade fascia. These critical components work alongside your siding to prevent moisture intrusion and keep your roofing system ventilated.
Preventive Maintenance Plans
Extend the life of your exterior with our professional maintenance plans. We pair our siding installations with routine inspections that include recaulking, paint touch-ups, and moss treatments, ensuring your home remains the best-looking house on the block for years to come.

Physical Board Damage: Look for boards that are visibly warped, cracked, or bubbling.
Aesthetic Deterioration: Faded colors or peeling paint are more than just an eyesore; they indicate that the protective layer of your siding has failed.
Compromised Seals: Noticeable gaps at the seams or around the trim allow moisture to penetrate your home's envelope.
Structural Softness: Siding that feels soft or "spongy" when pressed often indicates underlying rot or water saturation.
Decreased Efficiency: An unexplained spike in heating or cooling bills can often be traced back to poor insulation from failing siding.
Biological Growth: The presence of visible mold, moss, or rot is a clear sign of excessive moisture retention.
Interior Moisture: Water stains appearing on inside walls or around window frames often originate from exterior siding leaks.
