Roofing Contractor in Tigard, Oregon
Tigard is really two towns. Down on the Fanno Creek flats, the roofing problem is water — where it goes once it leaves the roof, on a lot that doesn’t drain. Up on Bull Mountain, it’s wind exposure and steep pitch. Same city, opposite problems, and a quote built for one doesn’t fit the other.
Jobin Roofing works throughout Tigard, fully licensed in Oregon (CCB #221810) and backed by 150+ five-star reviews. We quote the lot you actually have — which on the flats means gutter capacity and downspout routing, and on the hill means fastening and access.

Tigard spans 1970s flats-side subdivisions through recent River Terrace construction, so we repair and replace across the full range:
- Architectural & composite shingles. The default roof across most of Tigard. Shingle roof repair for worn or wind-lifted areas, through to full replacement detailed for pitch and exposure.
- Metal roofing. Standing-seam and metal panel roofs that shed our wet winters and resist moss. Metal roof repair — re-sealing failed fasteners and flashing — plus new installs and metal roof replacement.
- Tile roofing. Concrete and clay tile roof repair on the newer hillside builds: cracked or slipped tiles and the underlayment beneath, which does the actual waterproofing.
- Cedar shake. Repair and honest assessment for the cedar roofs still in service on older Tigard homes.
- Flat & low-slope. Membrane systems for additions and Tigard Triangle commercial buildings, where standing water and open seams are the usual failure points.
Two Tigards, two different roofs
On the Fanno Creek flats, the roof itself is often fine and the problem is volume — a correctly shingled roof dumping more water than the gutters can carry onto a lot that already doesn’t drain, which ends as standing water at the foundation. That’s a gutter and routing problem, not a shingle problem, and quoting it as a reroof misses it entirely. Up on Bull Mountain the picture inverts: drainage is rarely the issue, but the slopes are steeper, the exposure is real, and fastening and access drive both the install and the price. We look at which Tigard you’re in before we quote, because a spreadsheet average serves neither one.
Tigard roof conditions
Local Climate & Roofing Conditions in Tigard
Tigard gets the standard Willamette Valley wet season — long, steady rain rather than heavy bursts — which is less about peak intensity and more about sustained volume over months.
What varies is the ground it lands on. The Fanno Creek corridor is low and flat with poor natural drainage; Bull Mountain rises several hundred feet above it with real wind exposure. The same rainfall behaves differently on each.
Flats versus hillside
On the flats, undersized gutters and short downspout runs put roof water directly against the foundation. Over a wet winter that’s a crawlspace and grading problem that started at the roofline.
On the hill, wind finds the starter course and the ridge. Steeper pitches also mean water moves faster into the valleys, so valley detailing carries more load than it does down below.
Both sides share the region’s moss pressure, particularly on north-facing slopes and anywhere mature trees shade the roof through the winter.
What protects a Tigard roof
- Gutters sized to the roof, not the house. Capacity calculated from actual roof area, with downspouts routed well clear of the foundation.
- Fastening spec’d for exposure. Proper nailing patterns, starter course at the rakes, and ridge fastening on wind-exposed hillside slopes.
- Valley detailing. Where steep pitches concentrate water, the valley work is what holds.
- Safe moss treatment. Non-abrasive care on shaded slopes, never pressure washing.

Tigard roofing FAQs
Do you offer free roof estimates in Tigard?
Yes — all of our roofing estimates in Tigard are free. We’ll assess the roof, photograph what we find, and give you honest pricing with no pressure to commit.
Water pools near my foundation every winter. Is that a roof problem?
Often it starts as one. On flat Tigard lots, undersized gutters and short downspout runs put the entire roof’s water right at the foundation. Before you regrade the yard, it’s worth checking whether the gutters are actually sized for the roof area — that’s a much cheaper fix.
Does a Bull Mountain home cost more to roof?
Sometimes, yes. Steeper pitch, wind exposure requiring heavier fastening, and tighter access for material delivery all factor in. We’ll spell out exactly what’s driving the number in the written estimate rather than quoting a flat per-square rate.
Do you do roof moss removal in Tigard?
Yes, and it’s one of our most common Tigard calls. We use safe, non-abrasive treatment — never high-pressure washing, which strips shingle granules and can void your manufacturer warranty. North-facing and tree-shaded slopes need it most.
Can you repair my roof instead of replacing it?
Often, yes. We do real repairs, not just replacements. If your roof has life left in it, that’s the answer you’ll get — in writing, with photos of what we found.
