Our Roofing Services
Architectural shingle replacements, structural deck rot remediation, ice & water shield barriers, and engineered attic ventilation.
Architectural Shingle Replacements & Tear-Offs
Complete tear-off down to bare structural plywood decking. We inspect and replace dry-rotted CDX sheathing, apply high-performance synthetic breathable underlayment, and install heavy-gauge Malarkey Highlander/Vista or CertainTeed Landmark architectural shingles engineered for 130 MPH Pacific Northwest storm winds.
Craftsmanship Specifications:
- Complete tear-off with thorough CDX sheathing dry-rot replacement
- SBS rubberized asphalt shingles (Malarkey) with Class 4 impact resistance
- Scotchgard 3M copper granules preventing green algae & moss growth
- High-performance tear-resistant synthetic underlayment (ASTM D226)
- 6-nail high-wind fastening pattern on every architectural shingle
Ice & Water Shield Barrier & Master Flashing
The difference between a roof that lasts 10 years and one that lasts 30 lies in water deflection. We install self-adhering SBS modified bitumen ice and water membranes at all valleys, eaves, and sidewalls, backed by custom 26-gauge metal step flashing and chimney crickets.
Craftsmanship Specifications:
- Dual-course ice & water membrane extending past heated wall lines
- Custom 26-gauge baked enamel step & counter flashing at masonry
- Engineered kick-out diverter flashing to protect wall envelopes
- Heavy-duty all-metal or silicone pipe boots replacing brittle neoprene
- Valley roll flashing with woven or closed-cut shingle integration
Engineered Attic Ventilation & Ridge Cap Systems
Oregon attics trap heavy winter humidity that rots rafters from the inside out. We calculate and balance intake and exhaust airflow adhering to the 1:300 code ratio, installing continuous low-profile baffled ridge vents and clear soffit intake airflow channels.
Craftsmanship Specifications:
- Balanced attic ventilation preventing attic condensation & dry rot
- Continuous external baffled ridge vent with high-profile hip caps
- AccuVent soffit airflow baffles preserving uninhibited intake flow
- Attic inspection for moisture vapor transmission & mold prevention
- Manufacturer system warranty registration & CCB #216419 sign-off
Roofing FAQs
Straightforward answers on tear-off procedures, moss-resistant shingles, flashing standards, and Oregon warranty coverage.
How do you handle rotted plywood decking discovered during tear-off?
We never shingle over compromised wood. When old shingles are stripped, our project lead inspects the bare sheathing. Any plywood sheets with delamination, water staining, or fungal dry rot are cut out to the center of adjacent rafters and replaced with fresh exterior-grade CDX plywood securely fastened with ring-shank nails.
Why do you recommend Malarkey rubberized shingles for Pacific Northwest homes?
Malarkey roofing products are engineered in the Northwest using NEX polymer-modified asphalt. The rubberized formulation gives the shingle rubber-like elasticity, preventing brittleness during freezing temperatures, resisting severe wind uplift up to 130 MPH, and featuring 3M Scotchgard copper granules that stop moss and algae from feeding on shingle limestone filler.
What is kick-out flashing and why is it critical in Oregon?
A kick-out flashing is installed where the eave of a roof intersects a vertical siding wall. Without it, gallons of rainwater running down the roof edge drain straight behind the siding into the wall cavity, causing catastrophic hidden rot. We custom-fabricate kick-out flashings on every roof installation.
Are your supervisors on-site during roofing installations?
Yes. Our experienced project managers personally oversee tear-off cleanliness, check flashing integrations at chimneys and skylights, and ensure full CCB #216419 building code compliance on every project.
