Home inspectors on the Seattle Eastside flag a short, predictable list: moss coverage, curling or lifting shingles, soft spots in the roof deck, failed flashing at chimneys and valleys, and sagging gutters. Age alone is rarely the problem — a clean, flat 23-year-old roof usually earns only a "nearing end of service life" note. Moss removal and safety items like missing railings are the cheapest fixes with the biggest payoff, because buyers routinely ask for credits worth two or three times the repair cost.
If you're selling your house soon, you don't want to put a bunch of money in — but you know how this works: the buyer's inspector shows up, finds a soft spot or a missing railing, and suddenly the buyer is trying to knock the price down by more than the repair would have cost. The goal isn't to make the house perfect. It's getting it to "okay" — fixing exactly what the inspector will flag, and nothing more.
Inspectors on the Seattle Eastside walk the roof (or fly a drone) and look for a short, predictable list. It helps to see your roof the way they will:
Notice what's not on the list: the roof's age by itself. A 23-year-old roof that's clean, flat, and not leaking often passes with a simple "nearing end of service life" note. An old roof plus visible moss and curling is what turns into a price negotiation.
Roof moss removal before selling is usually the best money a seller spends, because it changes how the whole house photographs and how the roof reads in the inspection report. A proper job on our wet-climate roofs means gentle removal — no pressure washing, which strips granules and shortens shingle life — followed by a treatment to keep it from coming right back before closing.
Cost drivers here are roof pitch, how established the moss is, and whether shingles have already been damaged underneath. If moss has been sitting for years, plan on a few shingle repairs coming with the cleaning. That's still far cheaper than a buyer's credit request.
One Kirkland homeowner told us plainly: "the inspection will require a railing." He was right. Anything the inspector can call a safety hazard — a missing railing on stairs or a deck, steps that feel unstable, a post that's barely hanging on — will show up in the report as a required item, and lenders sometimes won't fund the loan until it's fixed. These are the "this one needs to be done ASAP" items.
Here's the honest trade-off, though. You don't need an expensive railing — you need a solid, code-compliant one, properly anchored so it never feels unstable again. Same with rotted deck boards or posts: if there is rot, it all has to go, because a repair that leaves compromised wood behind will fail the re-inspection. But often it's "just the steps" or "just these two" boards, not the whole deck. A good contractor will tell you which boards to save and which are truly deteriorated, instead of quoting a full rebuild you don't need.
Watch for the classic Eastside carport and porch problem: a post that was never treated lumber, or is missing a bolt at the base. Those typically last 15 or 20 years before they rot out at the bottom. Replacing a post with a proper treated post and correct hardware is a modest job — leaving it means the inspector writes "structural concern," which is the phrase that kills deals.
Washington sellers fill out a disclosure form, and anything you know about, you must disclose. So for each issue, ask three questions:
What you shouldn't do is over-improve. A full roof replacement rarely returns its cost on a house you're leaving — unless the roof is failing, in which case the sale price will reflect it either way and it's worth a real conversation.
Everyone's first question is "how much," and the honest answer is: it depends on what we find when we open things up. The main drivers are:
Get a couple of quotes — that's smart, and any contractor worth hiring won't be offended.
Yes, in almost every case. It's one of the least expensive exterior fixes, it improves listing photos, and it removes the most common roof flag in Eastside inspection reports. Just make sure it's done without pressure washing.
Inspectors don't pass or fail houses — they report conditions. An old roof with no active problems gets noted as aging; an old roof with moss, curling shingles, or soft spots gets flagged as needing repair or evaluation, and that's what triggers negotiations.
You can disclose most things instead of fixing them, but safety items like missing railings often become lender requirements, meaning the sale can't close until they're done. Fixing small safety and water issues up front is usually cheaper than the credits buyers demand.
Give yourself four to eight weeks before photos. Moss removal, railing work, and rot repair are quick individually, but summer schedules fill fast on the Eastside, and you don't want repairs happening while the house is on the market.
