Roofing systems

Every commercial system.
Expertly installed.

We install every major commercial roofing system on the market. Each one has specific strengths depending on your building type, budget, and exposure to coastal weather.

TPO Roofing
Thermoplastic polyolefin is the most popular commercial single-ply membrane in Oregon. Heat-welded seams create a monolithic waterproof surface. Energy Star rated white membrane reflects UV and reduces cooling costs. 15-30 year warranties.
Best for: Most commercial buildings. Best balance of cost, durability, and energy efficiency.
$6.50 - $10.00/sqft
EPDM Roofing
Ethylene propylene diene monomer (EPDM) is a synthetic rubber membrane with a 50+ year track record. Available in black (heat-absorbing) or white (reflective). Extremely flexible, handles thermal expansion without cracking. Ideal for large flat roofs.
Best for: Large flat roofs, warehouses, cost-conscious builds.
$5.50 - $8.50/sqft
PVC Roofing
Polyvinyl chloride membrane with superior chemical resistance. Handles grease, oils, and restaurant exhaust without degradation. Heat-welded seams, fire-resistant, and Energy Star rated. The premium single-ply choice.
Best for: Restaurants, kitchens, industrial, chemical exposure.
$7.50 - $12.00/sqft
Built-Up Roofing (BUR)
The original flat roof system, built with multiple layers of asphalt and reinforcing fabric topped with gravel or a cap sheet. Proven performance over decades. Excellent puncture resistance for high-traffic rooftops.
Best for: Large structures, rooftop HVAC, high-traffic areas.
$7.00 - $11.00/sqft
Modified Bitumen
Evolved from BUR with polymer-modified asphalt sheets. Torch-applied, cold-applied, or self-adhering options. Excellent elongation handles building movement. Two-ply systems offer redundant waterproofing.
Best for: Buildings with expansion/contraction, moderate budgets.
$6.00 - $9.50/sqft
Commercial Metal
Standing seam and R-panel systems for commercial buildings. Maximum lifespan, minimal maintenance. Ideal for retail, warehouses, and buildings with sloped or low-slope rooflines. 50+ year lifespan.
Best for: Retail, warehouses, sloped commercial buildings.
$10.00 - $18.00/sqft

Flat roof specialists

Flat roof
expertise.

Flat and low-slope roofs are fundamentally different from residential pitched roofs. Water doesn't run off — it pools. Every seam, every penetration, every drain detail has to be engineered for standing water resistance. That takes specialized knowledge most residential roofers don't have.

Positive drainage design with a minimum 1/4" per foot slope to drains
Heat-welded seams on all TPO and PVC to eliminate adhesive failure risk
Tapered insulation systems for ponding correction on existing roofs
HVAC curb flashing and penetration sealing to manufacturer specs
Roof access hatch installation with safety rail compliance

Why Flat Roofs Fail

90% of commercial flat roof failures come from three things: poor drainage design, failed seams at penetrations, and trapped moisture under the membrane. We address all three during our assessment before any work starts. If your current roof has ponding water visible 48 hours after rain, it needs drainage correction — not just a new membrane on top of the same problem.

Infrared Moisture Detection

Before we recommend a full replacement, we scan your existing roof with infrared imaging to map moisture intrusion. If only 10-15% of your roof deck is wet, a targeted repair and overlay may save you 60% compared to a full tear-off. We show you the infrared images so you can see exactly where the problems are.

Code Compliance

Oregon commercial roofing codes require specific fire ratings, wind uplift resistance, and energy efficiency standards. We handle all code compliance, permit applications, and final inspections. Your roof will meet or exceed current IBC and Oregon Structural Specialty Code requirements.

Building types

We've roofed
every type.

Retail & Restaurants
Your business stays open while we work. We schedule around your hours, contain all work areas, and ensure zero disruption to your customers. Grease trap ventilation and restaurant exhausts handled with PVC membrane.
Warehouses & Industrial
Large-format roofing for 10,000+ sqft buildings. BUR and TPO systems designed for foot traffic from HVAC technicians. Roof curbs, penetrations, and drainage engineering included.
Churches & Community
Complex rooflines with steeples, dormers, and mixed slopes require experience. We've roofed churches, community centers, and municipal buildings throughout Lincoln and Tillamook counties.
Multi-Family & HOA
Apartment complexes, condos, and townhome developments. We handle HOA coordination, phased installation to minimize tenant disruption, and warranty documentation for property managers.
Preventative maintenance

Maintenance plans
that pay for themselves.

A commercial roof that gets annual maintenance lasts 25-40% longer than one that doesn't. Our maintenance plans catch small problems before they become emergency repairs — saving you thousands over the life of your roof.

Bi-annual inspections (spring and fall)
Drain clearing and debris removal
Seam and flashing integrity testing
HD photo documentation and condition reports
Priority scheduling for any needed repairs
Written roof condition score trending year-over-year
The math is simple
Average commercial roof lifespan without maintenance
15-18 years
Average lifespan with annual maintenance
22-28 years
For a 10,000 sqft TPO roof ($75,000 replacement)
$30,000+ saved
by extending the roof life 8-10 years through maintenance
Code compliance

Every code.
Every permit.

Commercial roofing in Oregon has strict requirements that residential contractors often miss. We handle all code compliance, permitting, and inspections as part of every commercial project.

Fire Ratings
Oregon requires Class A fire-rated roof assemblies on most commercial buildings. We install and document FM-approved assemblies that meet or exceed UL 790 and ASTM E108 standards.
Wind Uplift
Coastal Oregon buildings face extreme wind uplift forces. We engineer attachment patterns based on FM Global 1-90 requirements specific to your building's height, location, and exposure category.
Energy Code
Oregon's commercial energy code (OEESC) requires minimum R-30 roof insulation for most building types. We design insulation systems that meet code and reduce your heating/cooling costs year-round.
Structural Load
New roof systems add weight. We verify structural capacity before specifying any system, especially on older buildings. If reinforcement is needed, we coordinate with structural engineers.
Permitting
We pull all required commercial building permits, coordinate with Lincoln County or Tillamook County building officials, and schedule the final inspection. Permit costs included in our quote.
Documentation
Every commercial project includes full documentation: manufacturer warranty registration, as-built drawings, maintenance instructions, and material spec sheets. Your property manager gets a complete binder.
