Roof pitch3/12 (low slope)5/12 (medium)7/12 (medium)9/12 (steep)10/12 (steeper)12/12 (very steep)

Pick the pitch that matches your roof - the rise over a twelve-inch run. From 9/12 up, crews tie off and work slower, and the price climbs. The Oregon default here is 5/12.

Expect quotes near $13,100 to $19,960 for a standard shingle re-roof in Portland, OR; that figure assumes a typical 1,940 sq. ft. single-story house. That covers a 5/12 roof of about 2,192 sq. ft. - 21.9 squares - with tear-off of the current shingles, new materials and the crew.

Ask any roofer for a per-square price and compare it with ours: $728.37 per square, installed. Two common step-ups: architectural 50-year shingles at $14,560 to $22,190, and steel shingles, the entry metal, from about $28,180.

Compared with $12,620 to $19,240 statewide, the Portland market adds about $580. Portland covers 49 ZIP codes in Multnomah, Washington and Clackamas counties; roofers based anywhere in that area usually quote these prices.

Comparing Roof Materials and Prices in Portland, OR

Your material choice moves the total more than any other decision. This table keeps the 2,192 sq. ft. roof fixed and swaps only what goes on top, old layer removal included.

These figures are not separate guesses. They run through our roof replacement calculator, metal roof calculator and flat roof calculator with the Pacific regional factor, which lands pitched roofs 23% above the U.S. average.

Price per Year of Roof

The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.

The Line Items Behind a Portland, OR Roofing Bid

A cheap bid and an expensive bid often describe two different jobs. On this 21.9-square Portland, OR roof, these items carry real dollars:

• Layers to remove. One layer costs roughly $3,830 to take off. Older homes sometimes hide a second layer, which adds near $2,480.
• Geometry. Four-sided hip roofs run about $1,580 above a gable; heavily cut-up roofs with dormers sit about $2,670 above it.
• Building height. Same roof, two stories up: about $1,140 more, mostly labor and safety staging.
• Skylight work. Budget about $440 for every skylight replaced or added during the re-roof.
• Decking. Nobody can see rotten plywood until the shingles come off. Get a written per-sheet replacement price so a surprise has a fixed cost.
• Trim items. Chimney flashing, pipe boots, ridge vents and drip edge may or may not be in a bid. Gutters usually are not - the gutter cost calculator prices them.
• Fees. Permit cost and debris hauling change from town to town. The quote should name both.

Put every quote on one sheet with the same rows - removal, underlayment, ice barrier, flashing, ventilation, decking, permit - and the real differences show.

Weather, Wear and Your Oregon Roof

Oregon's winters average highs near 41°F and lows near 26°F; summer highs average about 84°F. On our climate map below, that puts it in Region 3. Those numbers translate into a short list of roof stressors in Oregon:

Where Shingles Live Longest: the Climate Bell

Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Oregon is Region 3. Hover any column.

Metal Roofing Prices in Portland, OR

Metal roofs come in a few families, and they do different jobs. The prices below are for a typical 1,940 sq. ft. single-story house in Portland, OR.

• Standing seam: $37,560 to $57,260. Long panels run from ridge to eave and lock together at raised seams, with the clips hidden underneath. No screws go through the face, so there are far fewer places for a leak to start. On this roof it runs about $28,060 more than architectural shingles.
• Steel shingles: $28,180 to $42,950. Aluminum shingles: $31,160 to $47,500. Short interlocking pieces stamped to look like asphalt, shake or slate. A good pick for a busy roofline, or for owners who want metal without the barn look. Steel stands up to hail better; aluminum stands up to salt air better.
• Stone-coated steel: $38,360 to $58,470. A steel base under a granule finish. You get the tile look at a small part of the weight of real tile.
• Copper: custom quote only. A copper roof is hand work by a sheet-metal specialist, and it is priced far above standing seam. It never needs paint and weathers to a green patina. Few homes cover the whole roof with it; dormers and entry roofs are the usual places.

In a rainy climate, smooth metal panels shed water fast and resist moss growth. The case for metal rests on how long you will stay. Keep the house for decades and one metal roof can replace two asphalt roofs; sell soon and the premium rarely comes back. For a particular panel or coating, run the metal roof calculator.

When to Re-Roof in Portland, OR

Summer and early fall bring the driest weather for roofing. Line up your bids before then.

What a Flat Roof Costs in Portland, OR

A flat roof the size of this home's 1,940 sq. ft. footprint would run, in Portland, OR:

• EPDM rubber: $18,360 to $23,850. Think of a heavy inner tube spread over the deck. The seams are glued, not welded, and over time they are its weak spot. It earns its place on small, simple roofs and in cold places.
• TPO, 60-mil: $15,810 to $20,530. White plastic sheet, welded at the seams. It stays light for years and keeps the rooms below cooler. Quality varies by maker more than with the other two, so ask which product the bid names.
• PVC, 60-mil: $19,110 to $24,820. It looks like TPO but has a longer service record, and it holds up better where water sits or oils land. Choose it for a busy roof deck or a spot that never drains well.

Price order in Portland, OR: TPO first, PVC last, with EPDM between them. Each figure covers new polyiso board under the membrane and stripping the existing layer. Small flat areas cost more per square foot, since edges, flashing and setup barely shrink. Make sure a new flat roof drains completely; trapped water and winter freezes are a bad combination. Run the flat roof calculator to match a specific membrane and drain layout.

Portland, OR Roofing Questions

Should my roofer get a permit in Oregon?

Most local building departments want one when the old roof comes off completely, and some send an inspector at the end. The contractor should file it; be cautious if a roofer asks you to.

How do I estimate my roof size?

Start with the area under the roof, including garages and porches, then allow for slope and waste. A 1,940 sq. ft. footprint at 5/12 becomes roughly 21.9 squares (2,192 sq. ft.). Compare bids on the same count.

How many working days does a new roof need?

Plan on a few days at most for an asphalt roof around 2,192 sq. ft. Complex shapes, a second layer or bad weather can stretch it.

Does homeowners insurance cover roof replacement?

Only for sudden damage such as wind, hail or a falling tree, never for plain wear. Certain policies cover an aging roof at its depreciated worth rather than full replacement. On a roof that costs $13,100 to $19,960 to replace, that gap is large, so check your settlement terms.
