Explore each material below to learn what sets them apart—and why our certified team is trusted to install them across Greater Seattle and beyond.

Asphalt Shingle Roofing

Asphalt shingles are the most widely used roofing material in the Pacific Northwest, offering a strong balance of performance, style, and affordability. Guardian’s experienced crews specialize in precision installation, detailed inspections, and proper ventilation to extend the life of every shingle roof.

• Installed using premium materials from GAF and Owens Corning, two of the most trusted names in roofing
• Available in a wide range of colors and architectural styles to suit any home
• Engineered for protection against rain, algae, wind, and daily wear
• Laminated architectural shingles enhance durability and curb appeal
• Includes expert flashing work and properly balanced ridge ventilation
• Maintenance and repairs available for nail pops, granule loss, or aging sealant

Our installations follow strict manufacturer guidelines and meet or exceed Pacific Northwest building codes. Every shingle roof we complete is backed by certified expertise and long-term performance.

Metal Roofing

Metal roofing systems offer exceptional durability, energy efficiency, and modern curb appeal—making them a popular choice for homeowners and businesses seeking long-term protection. At Guardian, we install standing seam and exposed-fastener metal panels engineered for Northwest conditions.

• Standing Seam Systems – Concealed fasteners and raised seams reduce leak potential and improve thermal movement
• Exposed-Fastener Panels – Budget-friendly profiles suitable for garages, shops, and accessory structures
• Reflective Coatings – Available finishes deflect solar heat, helping reduce energy costs in the summer
• Low Maintenance – Resistant to moss, algae, and rot with fewer long-term repair needs than traditional shingles
• Longevity – Lifespans of 40–70+ years, depending on material grade and finish

Guardian’s metal installations are precision-measured and mechanically seamed for a weather-tight finish. We also offer underlayment systems with high-temp ice and water shields to protect valleys, eaves, and transition points where leaks often start.

Every metal roof is built to withstand wind uplift, falling limbs, and seasonal freeze-thaw cycles—ideal for homes in wooded or high-exposure areas.

Cedar Shake Roofing

Cedar shake roofs bring natural beauty and traditional craftsmanship to homes across the Pacific Northwest. Their rugged, textured appearance adds depth and curb appeal, especially on historic or lodge-style architecture. Guardian installs and restores cedar roofs with attention to structural detail, drainage, and long-term preservation.

• Crafted from Western Red Cedar: valued for its stability, rich color, and resistance to decay
• Natural insulation: helps reduce heating and cooling costs throughout the year
• Custom-spaced installation: allows for proper expansion and water shedding, which is critical in wet climates
• Preservative treatments: available to protect against fungal growth and premature rot
• Hand-split and taper-sawn shakes: provide different thicknesses and textures for architectural flexibility

With proper ventilation and regular maintenance, cedar shake roofs can last 30–40 years or more. Guardian’s team is trained to install breathable underlayments, corrosion-resistant fasteners, and fire-retardant coatings when required by local code.

For homes surrounded by trees or moisture-prone areas, we also offer expert moss-proofing and cleaning services that protect cedar shake roofs without damaging the wood grain.

Tile Roofing

Tile roofs are prized for their elegance, strength, and longevity—making them a premium option for homeowners who value both performance and aesthetics. Guardian installs clay, concrete, and composite tile systems with structural reinforcement and precision alignment.

• Clay Tiles – Naturally colorfast and resistant to UV degradation, ideal for Mediterranean-style homes
• Concrete Tiles – Durable and cost-effective with a wide range of textures and finishes
• Composite Tiles – Lightweight alternatives that replicate the look of slate or wood shake
• Fire-Resistant – Tile is non-combustible, meeting Class A fire ratings in most assemblies
• Wind and Impact Tested – Engineered to withstand heavy storms and falling debris

Tile roofs often weigh more than asphalt or metal systems, so Guardian inspects roof decks and trusses to ensure proper load support. Our crews also install water-shedding underlayment and custom flashing around hips, ridges, skylights, and valleys.

Properly installed and maintained, tile roofs can last 50 to 100 years and often outlive the structure beneath them.

Flat & Low-Slope Roofing

Flat and low-slope roofs require specialized materials and installation techniques to ensure proper drainage and leak prevention. Guardian installs durable, energy-efficient systems for both residential and commercial buildings.

• Modified Bitumen (ModBit) – Multi-layered asphalt-based membrane ideal for small commercial and residential flat roofs
• TPO (Thermoplastic Polyolefin) – Heat-welded seams and UV resistance make this a top choice for energy savings and durability
• PVC (Polyvinyl Chloride) – Chemical-resistant and reflective, ideal for restaurants, manufacturing spaces, and high-exposure areas
• Built-Up Roofing (BUR) – Classic multi-ply system that offers redundancy and high impact resistance
• Custom Tapered Insulation – Designed to improve drainage and prevent ponding water

Flat roof installations by Guardian include substrate preparation, moisture barriers, and precision seam welding to reduce long-term maintenance needs. Our team is trained to navigate vent pipes, mechanical curbs, and skylight transitions that often pose challenges on low-slope designs.

These systems are ideal for commercial buildings, multi-family residences, and modern homes with clean architectural lines.
