Metal Roof Replacement in Portland, OR

Portland sits where the Willamette meets the Columbia, ringed by the forested West Hills and the Cascade foothills, and that geography writes the story of every roof here. About 36 inches of cool-season rain falls from October to May, so moss, algae and Douglas fir needle litter build up on shaded slopes across Irvington, Laurelhurst, Sellwood and the West Hills. Add east winds out of the Columbia Gorge, occasional winter ice storms, and dry summers with wildfire smoke and ember risk in the foothills, and shingle roofs age faster than most homeowners expect. When the granules are gone, the deck is soft, or the moss has won, a Metal Roof Replacement in Portland gives you a roof that sheds moss, resists ember intrusion and holds up for decades. We tear off the old roof, inspect and repair the decking, then install a complete new metal system built for this climate. If your roof is still serviceable but failing in spots, start with metal roof repair, and call (971) 754-2587 when replacement is the honest answer.

Why Metal Roof Replacement Matters on Portland's Older and Newer Roofs

Portland's housing stock runs from 1900s Craftsman bungalows and Foursquares in Alameda and Kenton to 1990s-2020s subdivision homes in Beaverton, Hillsboro and Happy Valley, and both ends of that range have roof problems. On the old houses, we routinely find three layers of shingle, soft deck boards around chimneys, and moss mats that have been holding water for years. On the newer homes, the original composition shingle is simply at the end of its life, and the homeowner wants a system that will outlast the mortgage.

• We tear off every layer down to the deck so we can see rot, delamination and old flashing failures before they get covered up.
• We replace rotten sheathing, fascia and drip edge, because a new metal roof over soft wood is a leak waiting to happen.
• We install ice and water shield in the valleys and along the eaves, which matters when Gorge winds drive rain sideways.
• We fit the new panels, ridge caps and pipe boots as a complete system, not a patch over old penetrations.
• We haul away all old roofing and leave the gutters clear, so your Saturday is not spent cleaning up our mess.

Every replacement ends with a walkthrough, photos of the deck and flashing, and a clear explanation of what we found under the old roof.

Key info: On a 1920s bungalow in Sellwood, we pulled off three layers of shingle and found rot around the chimney chase that had been hidden for a decade. Replacing the roof without fixing that deck would have meant a leak inside the first winter.

Roofing permits are commonly required for a full replacement or re-roof in Portland and the surrounding jurisdictions, and thresholds, fees and inspection requirements vary, so always confirm the current rules with the local building department. You can start with the City of Portland's permitting information at portland.gov/ppd.

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

We start with an on-site inspection of the roof, attic and gutters, because the slope, the deck condition and the number of existing layers decide what the job actually is. From there we write a scope that names the panel profile, the underlayment, the flashing details and the deck repairs, so nothing is left to a verbal handshake. Most replacements in Portland follow the same sequence.

1. We walk the roof and attic with you, measure the squares, and photograph the problem areas.
2. We pull the permit with the local building department and schedule the tear-off.
3. We remove the old roofing, haul it away, and inspect every square foot of decking.
4. We replace rotten sheathing and fascia and refasten loose boards.
5. We install underlayment, ice and water shield, and new drip edge and valley metal.
6. We install the panels, ridge, hips, pipe boots and chimney flashing as one system.
7. We clean the gutters, magnet-sweep the yard, and walk the finished roof with you.

If you are weighing a full tear-off against a retrofit, our metal roof over shingles page explains when a recover is legal and sensible and when it is not.

Key info: A daylight ranch in Milwaukie had a low-slope rear roof covered in failing shingle and a steep front gable in decent shape. We replaced the whole roof in one pass with a standing seam profile that handles the low slope, instead of patching half the house and coming back in five years.

For a closer look at the panel systems we install, see our standing seam metal roofing page.

Replacement Approaches We Use Across Portland

Not every Portland roof wants the same metal system. A steep Tudor in Eastmoreland, a low-slope ranch in Lents and a barn workshop out toward Forest Grove each call for a different profile, fastener strategy and flashing detail. This table shows the main approaches and where each one fits.

We will tell you which approach your roof actually needs, and we will not sell a premium panel onto a shed that a ribbed profile handles fine.

Metal Roof Replacement Cost in Portland: What to Expect

Replacement pricing in Portland starts from $9 per square foot for a straightforward tear-off and metal install, and climbs from there based on what the roof actually demands. The biggest cost drivers are the number of old layers to remove, the condition of the decking, the pitch and complexity of the roof, and the panel system you choose. A simple gable ranch in Gresham and a steep, cut-up Tudor in the West Hills are not the same job even at the same square footage.

• Deck repairs and rotten sheathing add cost, and we price them from photos before we start.
• Steep pitches and multiple valleys slow the crew and require more safety rigging.
• Standing seam, stone-coated steel and copper sit above basic corrugated panels on price.
• Chimney, skylight and bay window flashing add detail work that a plain roof does not have.
• Historic district or HOA design review can add time and limit your profile and color choices.

Getting two or three written estimates is smart, as long as you compare the same scope: same tear-off, same deck repairs, same underlayment, same flashing. Our full pricing overview breaks down the numbers in more detail.

What to Look For in a Metal Roofing Contractor Near Portland

Hiring a roofer near Portland is mostly about verification, not sales talk. Get two or three written estimates with the same scope so you can compare line by line, and ask for local references from jobs in your part of town. If your house sits in a historic district or under an HOA, confirm who handles the design review before panels are ordered. And confirm who pulls the roofing permit, because the homeowner is the one left holding the problem if the paperwork is wrong.

Metal Roof Replacement Near Me: What Portland Homeowners Should Know

When you search for metal roof replacement near me, the results all look alike, so here is what actually separates a good job from a callback. The crew should be able to explain how they will handle your specific roof, not recite a brochure. They should know that moss and needle litter on shaded slopes in the West Hills and Eastmoreland need to be addressed before the new roof goes on. And they should be honest about when a repair makes more sense than a full replacement.

If your metal roof is leaking or losing fasteners rather than failing entirely, our metal roof leak repair and screw replacement and re-fastening pages cover the repair side. Call (971) 754-2587 and we will tell you which path your roof is on.
