Serving the Portland metro · Licensed OR CCB #221810 · WA #JOBINRL824MZ
Roofing Contractor in Portland, Oregon
Portland has some of the oldest and most distinctive housing in the metro — block after block of pre-1940 Craftsman, Four-Square, Tudor, and Victorian homes across neighborhoods like Alameda, Laurelhurst, and Ladd’s Addition, all under one of the densest mature tree canopies in the country. Those two things — complex older rooflines and heavy canopy — are what define roofing here.
Jobin Roofing serves Portland homeowners from across the river, fully licensed in Oregon (CCB #221810) and backed by 150+ five-star reviews. Older homes with steep, detailed rooflines need a roofer who respects how they were built and gets the details right — and that’s the work we’re known for.

We provide roofing across all five Portland quadrants — North, Northeast, Southeast, Southwest, and Northwest Portland — including Alameda, Laurelhurst, Irvington, Hawthorne, Sellwood, Mt. Tabor, Ladd’s Addition, Alberta, Eastmoreland, and the surrounding neighborhoods on both sides of the Willamette.

Portland’s mix of century-old houses and newer builds means we repair and replace across the full range of roofs in the metro:
- Architectural & composite shingles. The workhorse roof on most Portland homes. Shingle roof repair for worn or wind-damaged areas, through to full roof replacement detailed for steep older rooflines.
- Metal roofing. Standing-seam and metal panel roofs that shed our wet winters and resist moss. We handle metal roof repair — re-sealing failed fasteners and flashing — plus new installs and metal roof replacement.
- Tile roofing. Concrete and clay tile roof repair: replacing cracked or slipped tiles and repairing the underlayment beneath, which is what actually keeps the water out.
- Cedar shake. Repair and honest assessment for the cedar roofs on many of Portland’s older character homes, which need careful attention in our damp, shaded conditions.
- Flat & low-slope. Membrane systems for additions, modern homes, and commercial buildings , where standing water and open seams are the usual failure points. Flat roof repair and replacement both covered.
Why Portland’s older rooflines need an experienced hand
A 1915 Craftsman or Tudor isn’t a simple gable — it’s steep pitches, multiple dormers, intersecting valleys, and original flashing details, and every one of those transitions is another place water can get in. On homes like these, leaks start at the details, not the open field of the roof, and a quick patch over the symptom doesn’t hold. We trace the real source, repair the flashing and valley work properly, and — on a full replacement — detail the new roof to fit the home rather than fight it.
Portland roof conditions
Local Climate & Roofing Conditions in Portland
Portland pairs classic Pacific Northwest wet — long, damp winters — with one of the heaviest urban tree canopies in the country. For roofs, that combination means constant moisture and constant debris.
Add in a housing stock full of steep, detailed older rooflines, and you get more shaded slopes, more valleys, and more flashing points than a typical newer home.
What canopy and old rooflines do to a roof
Heavy shade keeps the north- and east-facing slopes damp the longest, and that’s where moss takes hold first — lifting shingles and holding water against the surface.
The same mature trees drop needles and leaves that pack gutters and valleys, so water backs up under the shingles and into the fascia.
On an older home, all of that lands on a roof with more valleys, dormers, and aging flashing details — more seams for water to work through than a simple modern roof has.
What protects a Portland roof
- Safe moss treatment. Non-abrasive care for canopy-shaded roofs — never pressure washing, which can strip granules and void the warranty.
- Clear gutters and valleys. Kept free of mature-canopy debris so water moves off fast instead of backing up.
- Flashing done right. Proper detailing at the dormers, valleys, and chimneys where older-home leaks actually begin.
- Ventilation on an older attic. Balanced intake and exhaust so a century-old roof deck dries out instead of quietly degrading.

Portland roofing FAQs
Do you offer free roof estimates in Portland?
Yes — all of our roofing estimates in Portland and across the metro are free. We’ll assess your roof, walk you through the options, and give you honest pricing with no pressure to commit.
Do you do roof leak repair in Portland?
Yes — roof repair in Portland is one of our most common local calls, especially on older homes where leaks start at the flashing, valleys, and dormers rather than the open roof. We trace the leak to its real source instead of patching the stain, and we can respond quickly across the metro from just over the river. If the roof is open to the weather, we’ll tarp it to stop the water while we schedule the permanent repair.
You’re based in Washington — do you serve Portland?
Yes — we’re fully licensed in Oregon (CCB #221810) and regularly work throughout Portland and the surrounding metro.
My home is an older Craftsman or Tudor — is roofing it any different?
Yes. Older Portland homes have steeper, more complex rooflines — more dormers, valleys, and flashing points — so leaks start at those details, and both repairs and replacements need to be detailed to fit the home. It’s work that rewards experience with historic housing.
Do you remove moss without damaging my roof?
Yes. We use safe, non-abrasive moss treatment — never the high-pressure washing that can strip shingle granules and void your manufacturer warranty. It’s especially important under Portland’s heavy tree canopy.
