Pitch drives both the roof area and the labor. Steep pitches (9/12 or more) slow the crew down, and low ones need extra underlayment care. Our Oregon starting value is 5/12.

In Gresham, OR, a typical 1,940 sq. ft. single-story house needs about $12,920 to $19,690 for a new asphalt shingle roof, old shingles off and hauled away. The roof itself measures about 2,192 sq. ft. (21.9 squares) at a 5/12 slope, and the price includes labor, materials and removal of the existing layer.

Divide it out and the installed rate is $718.54 per square; a square is the hundred square feet roofers quote by. Two common step-ups: architectural 50-year shingles at $14,360 to $21,890, and steel shingles, the entry metal, from about $27,800.

Compared with $12,620 to $19,240 statewide, the Gresham market adds about $370. Every one of the 2 Gresham ZIP codes in Multnomah County uses the prices on this page.

Comparing Roof Materials and Prices in Gresham, OR

The roof stays the same size in every row below; only the covering changes. Each price includes tear-off of one layer, and the range shows how far honest bids usually spread.

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 21% 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.

Reading a Gresham, OR Roofing Quote Line by Line

Before you rank quotes by price, check that they cover the same work. Our model values each variable on the 21.9-square roof like this:

• Tear-off. About $3,780 of the quote pays to strip and dispose of one layer; if the roofer finds two layers, figure another $2,450 or so.
• Roof shape. When every side of the roof slopes down to a gutter (a hip design), add close to $1,560 over a two-sided gable. Plenty of dormers and valleys raise the add-on to about $2,630.
• Height. A second story adds roughly $1,120 to the same roof, because every bundle goes higher and safety setup takes longer.
• Openings. Plan near $430 per skylight that gets replaced or added while the roof is open.
• 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.
• Accessories. Ridge vents, pipe flashing and drip edge belong in the scope. If the gutters are due too, run them through the gutter cost calculator.
• Fees. Permit cost and debris hauling change from town to town. The quote should name both.

Ask each bidder to fill in the same list: tear-off layers, underlayment, ice barrier, flashing, vents, decking rate, permit. Gaps in that list explain most low bids.

How Oregon Weather Ages a Roof

Averages for Oregon: summer highs around 84°F, winter highs around 41°F, winter lows around 26°F. The map below files it under Region 3. What that means for materials and installation 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.

Pricing a Metal Roof in Gresham, OR

Metal is not one product. Long panels, metal shingles, stone-coated tiles and copper each solve a different problem, and the price gap between them is wide.

• Standing seam: $37,060 to $56,480. 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 $27,680 more than architectural shingles.
• Steel shingles: $27,800 to $42,370. Aluminum shingles: $30,740 to $46,860. If the neighbors would frown at ribbed panels, this is the answer. From the curb they read as shingles or shake. Aluminum is lighter and never rusts; steel costs less and takes a hailstone better.
• Stone-coated steel: $37,840 to $57,680. Steel tiles with a coat of stone granules. They are quiet in the rain, hard to dent, and look like tile or shake from the street.
• 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. Owners who stay put get the most from metal, because the long service life is where the savings sit. The metal roof calculator prices each panel style separately.

Flat and Low-Slope Roof Prices in Gresham, OR

Low-slope sections need a sealed membrane instead of shingles. Priced across the whole 1,940 sq. ft. footprint, a membrane roof in Gresham, OR costs:

• EPDM rubber: $18,120 to $23,530. This is the black rubber sheet on many older flat roofs. Big sheets mean few seams. It stays soft in deep cold and any roofer can patch it, which makes it a good fit for a garage or a back porch.
• TPO, 60-mil: $15,590 to $20,250. It goes down in sheets that the crew fuses together with a hot-air gun, so there are no glued seams to fail. A common pick when the flat roof sits over a bedroom or a kitchen.
• PVC, 60-mil: $18,850 to $24,490. Also white and heat-welded, but tougher against grease, chemicals and standing water. It is the pick for roof decks, low spots that hold puddles, and anything near a kitchen exhaust.

Ranked by price for this home, TPO is cheapest, EPDM is next, and PVC costs the most. Tear-off of one existing layer and new polyiso board are part of each figure. A small section will price higher per square foot. In Oregon winters, puddles on a flat roof freeze, thaw and creep into the seams. Clear the drains often, and ask for tapered fill at any low spot during the re-roof. Run the flat roof calculator to match a specific membrane and drain layout.

Gresham, OR Roofing Questions

How many squares is my roof?

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.

What permits does a Oregon roofing job need?

Usually. Permit rules are set locally, and most require one for a complete re-roof. A licensed roofer pulls it in their own name.

Will insurance pay for my new roof?

Insurance covers storm and impact damage, not wear. A worn-out roof is a maintenance cost - here about $12,920 to $19,690 for asphalt. After a storm, take photos and have a roofer look before you open a claim.

How long does a re-roof take?

For roughly 21.9 squares, a full crew usually finishes asphalt in a few days. Metal panels and roofs with many valleys take longer.
