Local roof concerns
Portland’s housing ranges from early-1900s bungalows and foursquares to mid-century ranches and new infill. A few issues come up again and again.
Rain for much of fall, winter, and spring means small flashing or shingle problems have plenty of chances to become leaks — and roofing work has to be planned around dry windows.
Firs and maples shade many Portland roofs, keeping them damp. Moss holds moisture against shingles and can lift their edges over time.
Many older homes have steep pitches, dormers, and brick chimneys. Some have spaced board sheathing or several layers of past roofing — things that matter when planning a replacement.
Strong east winds and occasional ice storms can lift shingles, break seals, and drop branches, especially on the east side of the metro.
Homeowner questions
A Portland mailing address doesn’t always mean the City of Portland handles permits. Some neighborhoods with Portland addresses are in unincorporated Multnomah, Washington, or Clackamas County. If your project needs a permit, the correct jurisdiction matters.
Oregon requires construction contractors to be licensed with the Construction Contractors Board (CCB). You can look up any contractor’s license status for free before signing. Big Bear Exteriors is Oregon CCB #239429.
Portland has historic and conservation districts where some exterior changes require review. If you’re thinking about changing roofing materials on a historic home, check the requirements first.

Neighborhoods
We work with homeowners across Portland’s neighborhoods — from century-old homes on the inner east side to hillside homes in Southwest. Here’s what roofs in each part of the city tend to deal with.
Early-1900s foursquares, bungalows, and old Portland homes with steep roofs, dormers, and brick chimneys. Irvington is a historic district, so some exterior changes need review.
Tall street trees, shaded roofs, and lots of moss. Laurelhurst is also a historic district, and many homes have chimneys that need new flashing during a reroof.
Hillside homes under tall firs on the west side, and mid-century ranches on the east side that take the brunt of winter east winds.
Materials & colors
The right roofing material depends on the home, roof design, drainage, budget, maintenance expectations, and how long you plan to stay. We explain the practical differences between options before anything is ordered — including shingles from Portland-based Malarkey, GAF, and Owens Corning.
Architectural (dimensional) shingles are the most common choice for a Portland roof replacement. They come in a wide range of colors and can be installed on most steep-slope roof designs. The right product depends on roof pitch, ventilation, flashing details, exposure, appearance, budget, and the manufacturer’s installation instructions.
For homes where the roof is a big part of the view, GAF Grand Sequoia recreates the look of a hand-split wood-shake roof with thick, oversized, irregular-cut shingles. It’s a common pick when replacing an old cedar shake roof.
Shingle manufacturers offer limited warranties on their products, and some offer longer system warranties when qualifying components are installed together. Coverage depends on the product line, registration, and following the manufacturer’s installation instructions. Your written estimate states which warranty applies to your roof, so you can compare it side by side with other bids.

FAQ
Sometimes, with careful planning. Tear-offs need a reliable dry stretch so the roof isn’t left exposed, and some materials have temperature requirements for proper sealing. Repairs and temporary protection are often possible between storms. Your project’s timing is discussed with your estimate.
Moss on a roof that’s being replaced comes off with the old roofing. On a roof that’s being kept, moss should be removed gently — aggressive pressure washing can strip granules and damage shingles. Trimming overhanging branches to let in light and air also helps.
Not necessarily, but chimneys are one of the most common leak sources on older homes. Step and counter flashing at the chimney should be inspected and, during a replacement, usually renewed. Masonry repairs such as repointing are typically a separate trade.
Many homes with Portland mailing addresses are in unincorporated county areas. Tell us your address or ZIP code when you contact us, and we’ll confirm whether it’s in our service area.
Compare scope, not just price: tear-off vs. overlay, how decking replacement is handled, underlayment, flashing, ventilation, materials, cleanup, and warranty terms. Our guide to what a roofing estimate should include has a checklist.
