Cracked tile, moss buildup, and failing underlayment on Portland-area homes — repaired by in-house crews who work tile as a standing service, not an exception. Serving the metro since 2004.
Where Tile Roofs Show Up in Portland — And Why They’re Hard to Get Serviced
Tile is a minority roof in this city, and that single fact explains most of what Portland homeowners run into when they need work done on one.
The overwhelming majority of it is concrete, and it went on in the 1980s and 1990s. That’s the era when tile got specified on custom and semi-custom builds across the metro — through the West Hills and up along Skyline, out into the West Slope, across the Lake Oswego hillsides, and into the newer subdivisions in Beaverton, Tigard, and Happy Valley. Mediterranean, Tuscan, and Spanish-influenced elevations mostly, though plenty of it landed on houses with no particular style argument for it beyond looking substantial.
That timing matters more than the architecture does. A concrete tile roof installed in 1988 is now approaching forty years. The tile itself is often fine — concrete tile routinely lasts fifty years or more. The underlayment beneath it does not. Original felt from that era typically gives out somewhere between twenty and thirty years, which means nearly every 80s and 90s tile roof in Portland is either past the point where the membrane has failed or arriving there now. That gap between a tile with decades left and a membrane already done is where essentially all of our tile work comes from.
Clay exists here, but barely — a handful of 1920s homes in the older eastside neighborhoods, and even there it’s uncommon enough that most Portland roofers have never touched it. If you have concrete tile, you have what nearly everyone here has.
The scarcity is the real problem. Tile is a small enough share of the Portland housing stock that most crews never build up reps on it, and the ones who do treat it as an occasional job rather than a specialty. We work on tile regularly, but it sits alongside the asphalt shingle repair, moss removal, and full replacement work we do across Portland — which is worth knowing, because a tile call frequently turns out to be a flashing, gutter, or dry rot problem that has nothing to do with the tile at all.
A company doing composition five days a week doesn’t develop tile habits. Where the load paths are. How to lift a field and set it back without a thirty percent breakage rate. How to source or work around a profile that hasn’t been manufactured since the Clinton administration. So you get one of three responses: a decline, a referral to someone an hour away, or — most commonly — a quote for full replacement, because a tear-off is a job they know how to price and a lift-and-relay isn’t.
That last one is the expensive mistake. A tile roof that needs new underlayment is not a tile roof that needs replacing. The tile comes off, gets stacked, the membrane and flashing get replaced, and the same tile goes back down. It’s real work and it isn’t cheap, but it’s a fraction of a tear-off — and it doesn’t put a fifty-year material in a dumpster at year thirty-five.
We’ve kept tile as a standing service since 2004 rather than treating it as an exception, and our crews are in-house and background-checked — no subcontractor learning your tile profile on your roof. We inspect from above and from inside the attic, photograph what we actually find, and give you the reasoning along with the number. Sometimes that reasoning is that nothing needs doing yet, which is not a conclusion a replacement-first contractor tends to reach.

Most individual tile repairs run $500 to $1,800. Larger sectional work — valley rebuilds, whole-house anti-ponding correction at the eaves — can run well over $10,000. Almost every tile job we quote falls into one of those two tiers, and the difference between them is scope, not severity.
Individual repairs: $500–$1,800
Cracked or slipped tile, a flashing reseal at a chimney or skylight, a traced leak source corrected at the point of entry, localized fascia or rake board rot. One area of the roof, opened and closed. Where you land in the range comes down to access, pitch, how many tiles have to be lifted to reach the problem without breaking more on the way in, and whether the underlayment beneath the repair area is still sound.
Sectional and whole-roof work: $10,000+
Valley rebuilds, anti-ponding correction across the eave line, and sectional underlayment replacement all require lifting and relaying tile across entire planes of the roof. The tile itself is usually still perfectly good — the cost is in removing it, stacking it, replacing what’s beneath, and setting it back with minimal breakage loss. These are the jobs a contractor who doesn’t work tile regularly will quote as a full replacement, because a tear-off is a job they know how to price and a lift-and-relay isn’t.
What moves the number
Number of damaged tiles · roof accessibility · pitch and height · valley condition · flashing at penetrations · skylight and chimney transitions · underlayment condition · availability of matching tile
Discontinued profiles are the wild card. If your tile is no longer manufactured, sourcing a match through salvage or a tile yard adds time and cost — though we can often relocate tile from an inconspicuous slope to the visible repair and put the imperfect match where nobody sees it.
Why we don’t quote tile over the phone
The difference between a $700 repair and a $12,000 relay isn’t visible from the ground or from a photo you send us. A contractor who quotes tile sight-unseen is either guessing high to protect themselves or setting up a change order later. We inspect, photograph what we actually found, and give you a number with the reasoning attached — including telling you when the honest answer is that nothing needs doing yet.
While concrete and clay tile roofs may appear similar from the ground, they have unique characteristics that influence repair methods and long-term maintenance requirements.
Concrete tile roofing is common throughout and Portland OR and the Pacific Northwest. These roofs are known for durability, impact resistance, and relatively low maintenance requirements. Over time, concrete tiles can experience:
Many concrete tile roofs remain structurally sound long after the underlayment beneath begins to deteriorate. In these situations, targeted repairs can often extend roof life substantially.
Clay tile roofs are highly durable and can last for generations when properly maintained. They are especially valued for their appearance and resistance to weathering.
Common clay tile issues include:
Because clay tiles can be more brittle than concrete tiles, repairs require careful handling and specialized techniques.
Our roof technicians have experience working with both concrete and clay tile systems and understand the unique repair requirements of each.
Our tile roof maintenance services may include:
Routine maintenance helps identify small problems before they become expensive repairs. It also helps ensure valleys and drainage paths remain clear during the heavy rainfall common throughout the Portland Metro area and the entire Vancouver Wa area as well.
For older tile roofs, restoration services can often improve performance and appearance while extending roof life. Restoration may include repairs, tile replacement, flashing upgrades, valley work, cleaning, and preventative maintenance recommendations.
Many homeowners are surprised to learn how much additional life can be achieved through proper maintenance and restoration.
Tile roofs have one of the longest service lives of any residential roofing system, but like any roof, they eventually develop issues. In many cases, the tile itself is not the primary problem. Common causes of tile roof failure include:
The waterproof underlayment beneath the tile often wears out long before the tile itself. Concrete and clay tile routinely last 50 years or more, while the felt underneath typically begins failing somewhere between 20 and 30 years — which is why a roof with perfectly sound tile can still leak. When that happens, the tile is carefully lifted and stacked, the underlayment is replaced, and the original tile goes back down, restoring the roof at a fraction of replacement cost.
Eave Flashing and Tile Roof Ponding Proper eave flashing is what determines whether water off a tile roof lands in the gutter or behind it. Most tile roofs have a gap beneath the tile behind the gutter line where water gets trapped instead of draining — a condition called ponding, which slowly rots fascia and feeds moisture back into the roof edge. The fix is a 1" x 11" drip edge flashing installed under the tile and under the felt underlayment, so every drop is carried past the fascia and into the gutter where it belongs.
Roof valleys carry more water than any other part of the roof, which makes them the first place wear shows up. Debris collects where two slopes meet, forming a dam that holds moisture against the metal valley flashing and accelerates corrosion, and tiles cut too tightly to the valley leave no room for that debris to flush through. Clearing and correcting valleys early is one of the highest-value repairs on a tile roof, because a failed valley sends water directly into the framing below.
Poor workmanship from previous repairs is one of the most common problems we find on tile roofs. Mastic and caulk smeared over cracked tile, mortar used where flashing belongs, and mismatched replacement tile all cover the symptom without correcting the path water is actually taking — and foot traffic from an untrained crew often breaks more tile than it fixes. Undoing a bad repair is frequently the first step in a proper one.
Moss is not just a cosmetic problem on a tile roof — it holds water directly against the underlayment and wicks moisture sideways underneath tiles that would otherwise shed cleanly. Needles, leaves, and moss also slow drainage and keep the roof surface damp through the long Pacific Northwest wet season, which shortens underlayment life measurably. Tile must be cleaned using low-pressure methods and treatment; pressure washing strips the surface finish on concrete tile and breaks clay tile outright.
High winds, falling branches, and impact from debris can crack or dislodge tile, exposing the waterproofing layer beneath. A single cracked tile rarely causes an immediate leak, because the underlayment is designed to serve as the backup — but it starts a clock, since that section is now taking direct sun and water it was never meant to handle. Storm damage is also frequently invisible from the ground, which is why a post-storm inspection is worth doing even when nothing looks wrong.
Understanding why a tile roof is leaking is critical. Repairing symptoms without addressing the underlying cause often leads to recurring problems and unnecessary expense.
Rotten fascia is one of the most common problems we find on tile roofs in Portland metro, and it is almost never a coincidence. When eave flashing is missing or installed incorrectly, water ponds behind the gutter instead of draining into it — and that trapped moisture sits directly against the back of the fascia board, season after season, until the wood softens and fails. By the time paint is bubbling or the gutter is pulling away from the house, the damage underneath has usually been progressing for years.
We repair and replace fascia board as part of tile roof work, including the rake boards and rafter tails that often deteriorate alongside it. Rot rarely stops at the fascia; once the board is opened up, we frequently find damage extending into the sheathing edge or the ends of the rafters, and all of it needs to be addressed before new material goes on. Gutters are detached, the compromised wood is cut out and replaced, and everything is primed and sealed before the gutters go back up.
The part that matters most is what happens next. Replacing fascia without correcting the eave detail that destroyed it means the new board starts rotting the day it is installed. Any fascia repair we do on a tile roof includes installing proper 1″ x 11″ drip edge flashing under the tile and under the underlayment, so water is carried past the fascia and into the gutter — which is the only thing that makes the repair permanent.
The Pacific Northwest presents unique challenges for tile roofing systems.
Frequent rainfall, seasonal moss growth, wind-driven storms, and temperature fluctuations all place stress on roofing materials over time.

Yes, but only along specific load paths — the lower third of each tile, directly over the batten, with weight distributed and shoes that don’t torque. Most cracked tile we find on inspection wasn’t damaged by weather; it was damaged by a gutter cleaner, satellite installer, or chimney sweep who stepped in the middle of the pan. Our crews are trained on tile specifically, and we’re in-house only, so the person on your roof isn’t a subcontractor learning on your house.
Because the tile is not the waterproofing layer — the underlayment beneath it is. Concrete and clay tile routinely last 50 years or more, while the felt or synthetic underlayment under it typically fails somewhere between 20 and 30 years. When a 1990s tile roof starts leaking, the tile is usually still serviceable. What’s failed is the membrane, the flashing, or the fasteners, and the repair is a lift-and-relay rather than a tear-off.
Often, yes. Discontinued profiles are salvageable from a few directions: tile pulled from inconspicuous areas of your own roof (behind a chimney, on a rear slope) and moved to the visible repair, reclaimed stock from tile yards, and blend-matching from close-profile current production. We’ll tell you honestly during the inspection whether an exact match is realistic or whether a deliberate blend is the better-looking outcome. Color also weathers, so a brand-new exact-profile tile can stand out more than a well-chosen salvage piece.
Most tile repairs run $400–$1,500, depending on access, how many tiles have to come off to reach the problem, and whether the underlayment beneath the repair area is still sound. Isolated cracked tile and a flashing reseal sit at the low end. Sectional underlayment replacement, valley rebuilds, and dry rot at the deck push toward the high end and occasionally past it. We quote after inspection, not over the phone, because tile problems are almost never visible from the ground.
Rarely — and that’s the honest answer that costs us work. A tile roof needs full replacement when the deck itself has failed structurally, when the tile is spalling or delaminating across the majority of the field, or when the underlayment has failed everywhere at once and the tile has become too brittle to lift and relay without heavy breakage loss. Everything short of that is a repair or a sectional relay. If a contractor’s first recommendation on a tile roof is a full tear-off, get a second opinion before you sign anything.
Tile is a minority roof type here, which is why it’s hard to find a contractor who works it regularly. It concentrates in specific pockets: custom builds from the late 1990s and 2000s in the West Hills, Mediterranean and Spanish Colonial Revival homes in Laurelhurst, Eastmoreland, and Alameda, and the hillside developments running out through Lake Oswego and the West Slope. There’s also older clay tile on 1920s-era homes in the inner eastside neighborhoods, which is a different repair problem than the concrete tile on newer construction. We work both, and we’ve serviced tile across the metro since 2004.
Because volume drives specialization, and tile is maybe a small percentage of the metro’s roofs. A crew that installs asphalt five days a week doesn’t build the habits tile requires — knowing where the load paths are, how to lift and relay a field without a 30% breakage rate, how to source a discontinued profile. So most local companies either decline tile outright, refer it out, or quote it defensively at a price that assumes they’ll break things. The other pattern you’ll run into is a company that only quotes tile as a full replacement, because a tear-off is a job they know how to do and a lift-and-relay isn’t. We’ve kept tile as a standing service since 2004 specifically because the gap exists, and our crews are in-house, so the person handling your tile isn’t a subcontractor hired for the week.
How often does a roof actually need cleaning around here?
It does, and it’s the most underrated cause of cracked tile in Clark County. Concrete tile absorbs a small amount of water; when we drop below freezing overnight after a wet stretch — which the Vancouver-Portland metro does repeatedly between November and February — that trapped moisture expands and stresses the tile from the inside. Tile that already has a hairline crack from foot traffic or debris impact is where it shows first. This is why we recommend fall debris removal before the freeze cycles start rather than waiting for spring.
We repair both — fascia, rake boards, and the dry rot underneath them are part of the roof system, not a separate trade. On a tile roof the connection is direct: the rake board carries the edge tile along the gable, and the fascia carries both the gutter and the eave closure. When either one softens, the trim that’s holding tile in place loses its fastening, and the tile above it starts to shift. Most of the rot we find starts from behind — water tracking off the tile edge, an overflowing gutter, or failed drip edge — so by the time paint is blistering on the face, the back side is usually further gone. We open it up during inspection rather than guessing, replace only the sections that have failed, and reset the edge tile and gutter afterward. Fascia and rake board work falls in the $700–$1,800 repair range depending on linear footage and whether the rafter tails behind it are affected, and carries our 2-year labor warranty.
