FAQ — Greater Seattle Metro

What is the most common roof damage in Washington?

In King County and Snohomish County, the most prevalent forms of roof damage are:

  • •Moss and Algae Infestation: Washington's cool, moist climate is ideal for moss growth — the single most common source of premature shingle failure in the region. Moss lifts shingles, retains moisture, and accelerates deterioration.
  • •Wind Damage: Puget Sound windstorms — particularly in fall and winter — can generate gusts of 40–70+ mph that displace shingles, especially on aging roofs. If there was a recent windstorm, contact Real Great Roofing for a free inspection.
  • •Flashing Failures: Flashings around chimneys, skylights, plumbing vents, and valleys are the most common source of active roof leaks in Seattle-area homes.
  • •Granule Loss from UV and Age: Years of Pacific Northwest rainfall and UV exposure cause asphalt shingles to shed their protective granule layer, reducing waterproofing ability.
  • •Debris Impact: Overhanging conifers — Douglas fir, cedar, and hemlock, common throughout King and Snohomish counties — drop branches, cones, and debris that abrade shingles and clog gutters.

Regular roof and gutter maintenance and Real Great Roofing's free inspections are the best defense against all of these damage types.

Washington State Roofing & Home Value — Greater Seattle Metro

A New Roof — One of the Best Investments for Seattle Metro Homeowners

In the competitive Seattle, Bellevue, Kirkland, and Sammamish real estate markets, a roof's condition has an outsized impact on a home's perceived value, insurance eligibility, and time on market. Washington real estate professionals consistently cite a deteriorated roof as one of the top factors that trigger price reduction negotiations, inspection failures, and deal terminations. A new roof, by contrast, is one of the highest-return improvements a seller can make.

Real estate data from the Greater Seattle Metro consistently shows that a new roof can increase a home's resale value by $25,000 or more — and more importantly, dramatically reduce time on market. A home that might sit 45 to 60 days with a failing roof can sell in 2 to 3 weeks with a new one. Sellers often avoid major inspection concessions or failed deals once a roof replacement has been completed before listing.

Real Great Roofing's free pre-sale inspection and competitive replacement pricing help homeowners and sellers make smart decisions before listing. We provide full documentation of the new roof's materials, installation, and warranty — documentation that is increasingly expected by buyers, buyers' agents, and mortgage lenders in the Seattle Metro market. If you're considering selling your home in King County or Snohomish County, a call to Real Great Roofing is one of the smartest first steps you can take.

What We Install

Roofing Systems We Install

Every material we specify is selected for durability in Pacific Northwest conditions — resistant to moss, moisture, and wind while delivering the performance King and Snohomish County homeowners expect.

Most PopularGreater Seattle Metro

Composite (Asphalt) Shingles

Architectural-grade shingles deliver 30–50-year lifespans, dimensional textures that complement Northwest architecture, and strong resistance to wind-driven rain, UV exposure, and algae growth — the most cost-effective full replacement option for most Seattle Metro homes.

50+ Year LifespanGreater Seattle Metro

Metal Roofing

Metal roofs offer 50-plus-year lifespans, exceptional weather resistance, and low maintenance — ideal for high-value homes across Bellevue, Kirkland, Sammamish, and the Eastside. Concealed fasteners shed rain fast and resist moss far better than most alternatives.

Flat Roof SpecialistGreater Seattle Metro

Low-Slope PVC & TPO Roofing

Heat-welded single-ply membrane systems for low-slope and flat sections common on modern homes across King and Snohomish County. Fully welded seams create a continuous watertight envelope that stands up to Pacific Northwest rainfall and ponding water.

King & Snohomish County

Our Roofing Services in the Greater Seattle Metro

From the first free inspection to final cleanup, we handle every phase of your roofing project with transparent pricing and a workmanship guarantee that backs up every install.

Free Roof Inspection

We inspect every component of your roof system and give you a clear, documented condition report before recommending any work. No obligation, no pressure — just honest information.

Full Tear-Off & Deck Inspection

Every replacement starts with a complete tear-off to the deck. We inspect and replace any rotted sheathing before a single piece of new material goes down — so your new roof starts on a sound foundation.

Ice & Water Shield Installation

We install ice and water shield at all eaves, valleys, and penetrations — the highest-risk zones in any PNW roof. This critical layer prevents the water intrusion that causes interior damage during the heaviest Pacific Northwest storms.

Insurance Claim Assistance

We document storm and wind damage thoroughly for your carrier, work within the insurance process, and rebuild your roof to original specification or better using code-compliant materials and methods.

Roof Cleaning & Moss Treatment

Soft-wash treatment removes moss and algae and applies anti-growth preventive treatments that extend the life of your existing roof — the most cost-effective maintenance service for any PNW homeowner.

10-Year Workmanship Warranty

Every installation is backed by our 10-year workmanship warranty on top of manufacturer coverage that comes with the materials. We stand behind every nail and shingle we install.

Built for the PNW

Engineered for Pacific Northwest Weather

King and Snohomish County roofs face steady rainfall, windstorms, and moss-promoting humidity year-round. Every replacement we install is engineered to resist moisture intrusion, reduce moss growth, and improve attic ventilation — extending the life of your roof and improving energy performance across all seasons.
