Roof Eaves Repair: What It Costs, and How to Tell Rot From Weathering

Roof eaves repair runs $9 to $34 per linear foot, or $500 to $2,600 for a typical job, according to HomeGuide. The more useful question is the one nobody answers: is the board actually rotted, or does it just look bad? Those are different problems with very different prices, and you can tell them apart yourself.

What the eaves actually are

The eave is the part of the roof that hangs past the wall. It is an assembly, not a part. The fascia is the vertical board across the rafter ends — the one your gutter is screwed to. The soffit is the panel closing off the underside. The drip edge is the metal flashing tucked under the shingles at the roof's edge. Behind all of it are the rafter tails, the actual roof framing. If the names blur together, here is the plain-language difference between fascia and soffit. What matters for repair is that these five things fail as a group, usually in that order, and the price depends entirely on how far down the list the water got.

What roof eaves repair actually costs

The headline number is really two numbers stacked. HomeGuide prices the components separately, and the combined eave figure is just the sum:

Watch the scope when you compare quotes. Plenty of pages quote the $9–$34 eave figure as if it were a fascia price. It isn't — it's fascia plus soffit, and using it for fascia alone overstates the job by roughly three times.

Is it rot, or is it just weathering?

Press a screwdriver into the board, firmly, at a shallow angle. Sound wood pushes back and the tip barely marks it. Rotted wood takes the tip with almost no resistance and comes away soft and crumbly. That single test separates a repaint from a replacement, and it is the one thing almost no article on this subject bothers to explain properly.

Probe several spots, not one — corners, board ends, and directly behind the gutter, where water sits longest.

Why eaves rot here — and it isn't the rain

This is the part most articles get backwards, mine included until I checked it. The Forest Products Laboratory publishes a decay hazard index for US cities. Ours is unremarkable.

Olympia is below the national average. The index is weighted for temperature as well as wet days, and decay slows right down below 50°F — so our long cool wet season is less destructive than a short warm humid one.

The second number settles it. FPL says serious decay happens only when wood is above fiber saturation — about 30% moisture content — and that a 20% reading is used in field inspections only as a conservative safety margin. Their own words: "Even in humid areas, RH is rarely high enough for a long enough period to bring the MC of wood above 20%." Damp air does not rot a fascia board. Liquid water does — and FPL names the source directly, listing "overflow from blocked gutters" among the causes of water damage to exterior trim. Paint then makes it worse once water is in: coatings "usually crack at the joint between two pieces of wood, water enters the wood through these cracks, and the coating slows drying."

Which is genuinely good news. Your eaves are not rotting because of where you live. They are rotting because water is being delivered to them and then held there, and both halves of that are fixable.

The drip edge nobody checks

Drip edge is the strip of metal under the shingle edge, and the International Code Council's own commentary says it "directs water away from fascia and rake trim." It is mandatory on shingle roofs under IRC Section R905.2.8.5, which Washington adopts without amendment.

Here is the part that matters for an older house: per ICC, drip edge became a requirement in the 2012 edition of the code. Before that it "was not previously required... unless it was part of the roofing manufacturer's installation instructions." So a South Sound house last re-roofed under an earlier code may legitimately have none, and that is often the actual reason the fascia went.

Rafter tails: the $500 job and the $4,000 job

This is the fork in the road. A rotted face board is trim. Rotted rafter tails are the roof structure, and InterNACHI's inspection text is blunt about how one hides the other: "Rotting fasciae can also be masking a lot of rot in the rafter tails, which can be very expensive to replace."

It also changes the paperwork. Pierce and Thurston County exemptions both stop at structural work, and IRC R105.2.2 excludes cutting a load-bearing member from "ordinary repairs." So a face-board swap is usually an ordinary repair; once rot reaches the tails it is structural, and that means a permit in most of the South Sound. Which is why a quote written without anyone looking behind the board is one to be suspicious of.

When to actually do this work

Late June through September, if you have the choice. Opening an eave leaves framing exposed for part of a day, and new wood wants to go up dry and be painted in weather that lets paint cure. Found soft wood in January? Worth a look now — but a planned replacement can wait for the dry window.

When not to call me

• The paint is peeling but the wood is hard. That is a painting job. I would be the wrong trade and the wrong price.
• You are re-roofing within a year or two. The gutters and drip edge come off anyway, so bundle it and pay the access once. I do not do re-roofs, so that advice costs me the job.
• Something is living up there. Get the exclusion done first, in the right season, or you are sealing the problem in.
• The rot is well into the rafter tails across a long run. That is framing work with a permit attached, and you want a quote written against what is actually behind the board.

Frequently Asked Questions

How much does roof eaves repair cost? HomeGuide puts eaves repair at $9 to $34 per linear foot, or $500 to $2,600 for a typical job. That is soffit and fascia together. Soffit alone runs $4 to $22 and fascia alone $5 to $12, so the combined figure is simply the two added up.

What are the eaves on a house? The eave is the part of the roof that overhangs the wall. It is an assembly, not one part: the fascia board on the vertical face, the soffit panel underneath, the drip edge tucked under the shingles, the rafter tails behind it all, and usually the gutter.

Is peeling paint on the eaves always rot? No. Paint fails from ordinary weathering too, especially on a south or west face. The test is mechanical, not visual. Press a screwdriver into the board. Sound wood resists the tip. Rotted wood takes it with almost no pressure.

Does repairing the eaves need a building permit in Pierce County? It depends where you live and how deep the rot goes. Unincorporated Pierce County exempts re-roofing within limits, Thurston County expressly exempts gutters and downspouts, and the City of Roy requires a permit to re-roof. Once rot reaches the rafter tails it is structural work and the exemptions stop applying.

Is drip edge required by code? Yes, on shingle roofs. IRC Section R905.2.8.5 requires drip edge at eaves and rake edges, lapped at least 2 inches and fastened no more than 12 inches on centre. It became a requirement in the 2012 edition, so plenty of older South Sound roofs do not have it.

When is the best time of year to repair roof eaves? Our dry window, roughly late June through September. Opening up an eave means the framing is exposed for part of a day, and new wood wants to go on dry and get primed and painted in weather that lets paint cure properly.

If you have found soft wood at the roofline and want a straight answer on how far it goes, get in touch for a free estimate — I will pull a section of gutter and actually look behind it rather than quoting off a photo. If the board itself is the problem, here is what fascia board replacement involves and costs. If it is the panel underneath, that is soffit repair. And if the gutter is what put the water there in the first place, start with the signs of a gutter that has stopped draining.
