Metal Roof Inspection in Portland, OR

A metal roof inspection in Portland is not a quick walkaround with a clipboard. Between the 36 inches of cool-season rain that falls from October to May, the Douglas firs and bigleaf maples overhanging roofs in Irvington, Alameda and the West Hills, and the east winds that funnel out of the Columbia Gorge, a metal roof here takes a specific kind of beating. We climb the roof, check every fastener and seam, probe the flashing, and tell you in writing how many years the panels have left. If you own a standing seam roof in Sellwood or a corrugated barn roof out in the Tualatin Valley, the inspection answers one question: repair now or plan a replacement. Call (971) 754-2587 to schedule. You can also review our metal roof repair service for what happens after the report.

Why Metal Roof Inspection Matters in Portland's Wet, Tree-Heavy Neighborhoods

Portland sits where the Willamette meets the Columbia, ringed by the forested West Hills and the Cascade foothills, and that geography drives the failure modes we find. Moss and algae colonize the shaded north slopes of Craftsman bungalows in Laurelhurst and Kenton. Fir needles pack the valleys of standing seam panels on Eastmoreland Tudor homes and hold moisture against the metal. On the low-pitched ranch roofs across Lents and Milwaukie, ponding water and backed-out fasteners show up first. An inspection catches these before they turn into a leak over a living room ceiling.

• We check fastener condition and torque, because backed-out screws on exposed-fastener roofs are the number one leak source we find.
• We inspect every seam and lap on standing seam and metal shingle roofs for opening, oil canning and fastener fatigue.
• We probe flashing at chimneys, skylights and sidewalls, where most Portland metal roof leaks actually start.
• We grade coating wear and paint chalk on stone-coated steel and painted panels exposed to summer UV and wildfire smoke.
• We assess moss, algae and needle litter buildup on shaded slopes and in gutters.
• We document everything in a written report with photos and a straight answer on remaining service life.

The report gives you a repair priority list, not a sales pitch for a new roof.

Key info: On a 1920s Four Square in Sellwood with two large bigleaf maples over the south slope, we routinely find gutter valleys packed with seed litter and moss holding water against the panel edges. That is a five-year leak waiting to happen, and an inspection catches it while a $400 cleaning and re-fastening still solves it.

How We Inspect a Metal Roof in Portland, Step by Step

We start on the ground and work up, because the roof plane tells you less than the transitions do. On a steep gable in Eastmoreland or a low-slope ranch in Gresham, the order stays the same. We photograph as we go, so you see exactly what we see. The whole process takes two to four hours on a typical house.

1. We review the roof history with you and note any active leaks, ice damming or storm damage from the last east wind event.
2. We walk the perimeter and check gutters, downspouts and the drip edge for overflow staining and moss buildup.
3. We climb and inspect panel surfaces, seams, fasteners and closures, marking every backed-out screw and open lap.
4. We probe flashing at the chimney, skylights, valleys and sidewalls, the spots where most leaks begin.
5. We check penetrations, snow guards and vents for sealant failure and rust.
6. We write the report: condition ratings, photo evidence, repair priorities and a remaining service life estimate.

You get the report in writing, usually within 24 hours of the visit.

Key info: A 1990s two-story in Beaverton with a screw-down panel roof had three active leaks over the garage. The inspection found 41 backed-out screws along one eave and a failed pipe boot, not a panel problem. Re-fastening and a new boot fixed it for a fraction of a replacement. That is the kind of call an inspection is supposed to make. For panel-specific issues, see our screw replacement and re-fastening service.

Inspection Approaches We Use on Portland Metal Roofs

Not every roof gets the same inspection. A copper porch roof over a bay window in the West Hills needs a different eye than a corrugated workshop roof on acreage near Forest Grove. We match the approach to the panel type, the pitch and the access. Here is how the main approaches compare.

If you are not sure which approach fits, the visit starts with a look and we tell you before we climb.

Metal Roof Inspection Cost in Portland: What to Expect

We start every metal roof inspection with a free estimate, so you know the scope and the price before anyone gets on the roof. Most residential inspections fall in a modest range once the roof size, pitch and access are known. A simple ranch in Milwaukie is not the same job as a steep West Hills Tudor with copper detailing, and the price reflects that. For a fuller breakdown of how we price work, see our pricing overview.

• Roof size and number of planes drive the time on the roof and the report length.
• Pitch and access matter: a steep gable or a roof over a deep porch takes longer and more safety setup.
• Panel type matters: standing seam, metal shingle, stone-coated steel and corrugated each need different checks.
• Tree proximity and debris load add time, especially where firs and maples overhang the roof.
• Written reports for buyers, sellers or insurance take longer than a verbal walkthrough.

Get two or three estimates and compare scope, not just the number, because a cheap inspection that skips the flashing is money wasted.

What to Look for When Hiring a Metal Roofing Contractor Near Portland

You want a contractor who climbs the roof, writes things down and does not lead with a replacement quote. Check references from jobs similar to yours, a standing seam roof in Tigard is not the same as a corrugated barn in Sherwood. Confirm who pulls the permit if repairs go beyond minor work, and check any HOA or historic district design rules before you commit to panel or color changes. And get at least two written estimates. You can reach us through our contact page to schedule a free estimate.

One more thing: ask whether the inspector will put the findings in writing. A verbal report is worth what you paid for it.

Key info: Roofing permits are commonly required for a full replacement or re-roof, and thresholds, fees and inspection requirements vary by jurisdiction across Portland, Beaverton, Gresham and Lake Oswego. Always confirm the current rules with the local building department before work starts.
