Metal roofing has become one of the fastest-growing choices among homeowners in Greater Seattle, and the reasons are straightforward. In a climate defined by heavy rainfall, wind, and extended damp seasons, metal outperforms most traditional roofing materials in durability, weather resistance, and long-term value. A properly installed metal roof can last 40 to 70 years, requires minimal maintenance, and sheds rain and debris with exceptional efficiency.
Integrity Roofing & Construction installs premium metal roofing systems throughout Greater Seattle. Whether you’re drawn to standing seam panels for their clean, modern profile or prefer the look of metal shingles that mimic traditional materials, we provide expert installation backed by our 20-year workmanship warranty and full Washington State licensing and insurance.

Types of Metal Roofing We Install
Standing Seam Metal Roofing
Standing seam is the most common and widely recognized metal roofing system. Vertical panels run from ridge to eave, with concealed fasteners at raised seams between panels. The concealed fastener design eliminates the most common points of failure in exposed-fastener systems and creates a clean, architectural aesthetic.
Metal Shingles
Metal shingles are designed to replicate the appearance of traditional roofing materials, including asphalt shingles, slate, and cedar shake, while delivering the longevity and weather resistance of metal. They’re popular for homeowners who want the performance benefits of metal without departing from a traditional roofline aesthetic.
Corrugated and Ribbed Metal Panels
Commonly used in agricultural and commercial applications, corrugated and ribbed panels are also appropriate for residential projects where a more industrial or cabin-style aesthetic is desired. They’re cost-effective and highly durable in the Pacific Northwest’s wet conditions.
Why Metal Roofing Performs Well in Greater Seattle
Superior Rain and Wind Resistance
Greater Seattle receives substantial annual rainfall, and homes along the Puget Sound corridor are regularly exposed to high-wind events. Metal roofing panels are rated for wind speeds of 120 mph or higher, and their smooth, interlocking surfaces direct water off the roof efficiently.
Moss and Algae Resistance
Unlike asphalt shingles, metal roofing does not provide an environment where moss or algae can take hold. This is a meaningful maintenance advantage in Greater Seattle, where moss growth is one of the most common and damaging issues for traditional roofing materials.
Energy Efficiency
Metal roofing reflects solar radiation rather than absorbing it, which reduces heat gain in the summer. Metal’s insulating properties when properly installed also contribute to overall home energy efficiency year-round.
Longevity
The typical lifespan of a metal roof is 40 to 70 years — roughly double or triple that of standard asphalt shingles. For homeowners planning to stay in their home long-term, the higher upfront cost of metal roofing delivers excellent value over the life of the material.
Common Metal Roofing Issues and How We Address Them
Panel Expansion and Contraction
Metal expands and contracts with temperature changes. If not properly accounted for during installation, this movement can cause fasteners to loosen or panels to buckle over time. Our installation process uses appropriate fastener systems that accommodate thermal movement correctly.
Improper Sealing at Penetrations
The areas where the roof is penetrated by vents, pipes, and skylights require careful flashing and sealing. We use high-quality flashing materials and sealants rated for metal roofing applications.
Surface Finish Wear
Metal roofing panels are factory-finished with coatings that protect against corrosion and UV degradation. We select products with high-performance coating systems rated for Pacific Northwest conditions.
Frequently Asked Questions About Metal Roofing in Greater Seattle
Is metal roofing loud in the rain?
A properly installed metal roofing system — with appropriate underlayment and insulation — is not significantly louder than any other roofing material during rainfall. The key is proper underlayment installation, which we include as standard.
How does the cost of metal roofing compare to asphalt shingles?
Metal roofing has a higher upfront cost than asphalt shingles. However, when the lifespan difference is factored in — 40 to 70 years for metal versus 20 to 30 years for asphalt — metal often delivers lower total cost of ownership over the life of the home.
Can metal roofing be installed over existing shingles?
In some cases, yes — depending on local code requirements and the condition of the existing roof. We always inspect the existing roof condition first and give you an honest assessment of whether this is a viable option for your home.
Does metal roofing attract lightning?
No. Metal is a conductor but does not attract lightning. In the event of a lightning strike, metal roofing disperses the energy more safely than combustible materials. Metal roofing is non-combustible and carries Class A fire ratings.
What warranty does Integrity Roofing provide on metal roofing installations?
All of our metal roofing installations are covered by our 20-year workmanship warranty. Material warranties vary by manufacturer and product; we’ll provide full warranty documentation for the specific system we install.
