Jesse built the maintenance plan around a simple idea: it's cheaper to keep moss off your roof than to let it come back and cost you years of roof life. Here's what a year on the plan actually looks like, and where he draws the line on what he will and won't promise.
Portland moss doesn't care that you had your roof cleaned last spring. It's already working back in — under branches, along shaded north slopes, in valleys that never fully dry out. One cleaning knocks it back. Staying on it every year is what keeps it from coming back at all.
Moss holds moisture against your shingles, breaks down granules, and works its way into fasteners and flashing over time — slow damage that adds up if nobody's checking on it. Jesse's seen homeowners on a yearly plan get another 5–10 years of life out of a roof that would've otherwise needed replacing early.
The treatment itself is the same safe, US-made product we use on every job — no zinc, no bleach, no peroxide — organic and EPA-registered, so it doesn't chew up your gutters, landscaping, or the roof it's meant to protect. It just needs about a month to fully soak in and do its work.
Every roof's schedule is a little different, but the plan itself has always covered the same four pieces — kept simple on purpose, because that's what actually protects a roof.
The base of every visit — moss and debris cleared off the roof, with gutters cleaned out on most homes at the same stop, so clogged downspouts aren't left to feed the next round of moss.
The long-term piece. Once you're on the plan, you're already scheduled to come back before moss re-establishes, and we contact you before every visit — with a full inspection and photos emailed afterward, not just the treated areas.
The same safe, US-made treatment on every job — registered organic with the USDA and EPA-certified, no zinc, bleach, or peroxide. It takes about a month to soak in and kill the spores at the root, and works best applied in spring or fall.
"Limited" on purpose — if an inspection turns up a lifted shingle, a worn pipe vent, or a nail backing out, we'll photograph it and quote it separately. We don't do full roof replacements, so if it's bigger than that, we'll say so and point you to a roofer instead.
We apply the treatment to the full roof, clear the gutters on most homes at the same visit, and let the product do its work over the following weeks.
While we're up there, we look past the moss — pipe vents, nail heads, shingle wear, anything that could turn into a leak — and photograph what we find.
You get the photos and notes emailed straight to you. If something needs attention, we'll say so plainly and quote it separately — nothing bundled in without you knowing.
We're already scheduled to be back before moss has a chance to fully re-establish. Most roofs run on this yearly rhythm indefinitely; heavily shaded roofs or ones catching up after years of neglect sometimes start on a twice-a-year schedule until they're caught up, then settle back to annual.
Jesse's tested plenty of treatments over 15+ years, and they all land in about the same place — they work, and they last about as long as each other. If someone tells you they can guarantee an exact month before your roof needs attention again, they're guessing. What we'll guarantee is the work itself: we do what we say we're going to do on your roof, every visit.
That's really the point of the plan. Instead of guessing when the moss comes back, we're already scheduled to be there before it's a problem again — and because we're on your roof every year, we catch the small stuff (a lifted shingle, a nail backing out, a clogged downspout) while it's still small, not after it's become a leak. Maintenance customers hear about problems when they're cheap to fix. Everyone else hears about them when they're not.
An annual treatment costs a fraction of what a neglected roof eventually costs you — in an early roof replacement, in gutter damage, in a leak that started as a nail nobody spotted.
"Roof preservation will save you money in the long run. Moss can and will deteriorate a roof."
The treatment has gotten better over the years. The philosophy hasn't changed: protect your home — your most valuable possession.
Jesse's spent 15+ years watching how other moss-treatment outfits operate around Portland, and he's built two policies around what he's seen.
We'll match a competitor's price — but only if they're fully legal: active CCB registration, workers' comp insurance, and Oregon Department of Agriculture chemical-operator licensing to apply moss treatment. That licensing requirement is real — Oregon requires anyone applying moss prevention or treatment to be licensed for it, and it's worth checking before you hire anyone, not just us.
Jesse's take on the spray-and-wait competitors: "They spray it on and you have to wait five or six months for the moss to fall off." He's skeptical of the caustic-solution treatments some companies push too: "I really would have to see that work to believe it."
We'll point you to two other companies we consider fully legal and legitimate, so you can get three bids total before deciding. Most contractors don't recommend their own competition. We'd rather you make an informed choice than a rushed one.
