Your roof is one of the most valuable parts of your home, but it’s also one of the easiest to overlook. Black streaks, algae, moss, lichen, and years of dirt buildup don’t just make your roof look old—they can trap moisture and contribute to premature deterioration.
At Fox Window & Gutter Cleaning Services, we’ve been helping homeowners throughout San Mateo County since 2011 with professional roof cleaning solutions that safely restore roofs while protecting their long-term performance. Our experienced team uses the appropriate cleaning method for your specific roofing material, delivering outstanding results without unnecessary risk.
We hear this a lot from Half Moon Bay folks: “I didn’t realize how bad it’d gotten until you cleaned it.” The foggy marine layer that rolls in off the coast keeps roofs damp for hours, especially in neighborhoods like Miramar and Princeton-by-the-Sea. That constant moisture is a perfect breeding ground for moss and lichen. We’ve tackled roofs on Wavecrest Road that looked green from the street, and after a gentle wash, they looked years younger.

Keeping it clean isn't just about appearance—it's an important part of preventative home maintenance, especially in Half Moon Bay's coastal climate.
A professionally cleaned roof dramatically enhances the overall appearance of your home and creates a great first impression. Drive up Kelly Avenue toward downtown, and a clean roof stands out.
Removing algae, moss, and debris helps reduce moisture retention and supports the long-term health of your roofing system. The salty air near the harbor can accelerate wear, so regular cleaning matters.
Routine roof cleaning helps homeowners maintain one of the most expensive components of their property. We've seen roofs in the Highlands neighborhood last an extra decade just from consistent care.
Professional cleaning removes algae, mildew, moss, and lichen before they continue spreading. Those tall cypress trees common in Half Moon Bay drop needles that trap moisture against shingles.
A clean, well-maintained roof contributes to higher perceived property value and improved marketability. If you're thinking of selling near the Ritz-Carlton area, a spotless roof really makes a difference.
Many homeowners don’t realize how much dirt and organic growth has accumulated until it’s removed.
If you’ve noticed any of these issues, it may be time for professional roof cleaning:
Ignoring these problems can lead to increased moisture retention, unnecessary wear, and a roof that looks much older than it actually is. The truth is, after a wet winter in Half Moon Bay—especially with the heavy rains we get between November and April—those dark streaks can spread fast. We’ve cleaned roofs off Highway 1 that hadn’t been touched in five years, and the difference was night and day.
Whether you have 10 windows or 100, we’ll get them clean—efficiently and safely. We’re trained and equipped to safely clean a wide variety of window styles and configurations, including:
We believe every roof deserves the right approach—not a one-size-fits-all solution. Up in the hills near Tunitas Creek, the clay soil and heavy fog create a different set of challenges than what we see in the flatlands near the harbor. That’s why we always do a walk-around first.
We’ve seen a lot of roofs in Half Moon Bay. And honestly, not a single one is the same. That’s why we never use a one-size-fits-all approach — your roof deserves a plan that matches its unique condition and location.
We start by inspecting your roof's condition up close. In Half Moon Bay, that means checking for moss buildup from the foggy mornings and any wind damage from those strong Pacific gusts. We figure out the safest way to clean it, every time.
Your roof type matters — whether it's composition shingles in the Miramar neighborhood or clay tiles in the wave-lashed homes near the harbor. We tailor the whole cleaning process around what's actually on your roof and how much algae or lichen has settled in.
Our crew uses proven techniques to knock off dirt, moss, and those ugly black streaks you see on so many roofs around Half Moon Bay. We're careful near skylights and solar panels too — the last thing you need is a leak after a storm.
Before we pack up, we walk the property line — from the street to the backyard. We check gutters, downspouts, and make sure all debris is cleaned off your driveway. If it's not right, we don't leave.
Since 2011, we’ve earned the trust of folks all over the Coastside — from the homes tucked along Wavecrest Drive to the ranches out on Higgins Canyon Road. We know what this climate does to a house, and we show up ready for it.
Look, we’ve seen companies roll through Half Moon Bay, blast a roof with pressure, and disappear. That’s not how we work. We take the time to inspect your roof, figure out what’s really growing on it (moss? algae? salt residue from that morning marine layer?), and then we get to work the right way.
Here’s what you’re choosing when you hire us:

Half Moon Bay, home to roughly 11,000 residents, anchors the San Mateo County coastline just 25 miles south of San Francisco. The city’s coastal fog and salt-laden air, especially in neighborhoods like Miramar and the stretch along Cabrillo Highway, create a persistent film on windows that standard cleaning can’t touch. This marine layer also brings frequent mist, leaving glass streaked even after a brief rain shower.
Tourism drives much of the local economy, with landmarks like Pillar Point Harbor, the Ritz-Carlton, and Mavericks Beach drawing visitors year-round. For property owners in Half Moon Bay, especially those near the coast or the downtown State Street area, sparkling windows aren’t just about curb appeal—they’re essential for maximizing ocean views and maintaining homes against the corrosive coastal conditions. Routine professional cleaning helps prevent hard water stains from the area’s mineral-rich municipal supply and extends the life of windows exposed to constant salt spray.
The marine layer and heavy fog, common from late spring through summer, deposit fine salt particles and moisture on windows. This means standard residential windows may need cleaning every 4-6 weeks to avoid a hazy film, especially in neighborhoods like Miramar. We recommend scheduling cleanings after extended foggy periods to prevent mineral buildup.
All window cleaning companies operating in Half Moon Bay are required to hold a valid City of Half Moon Bay Business License, registered with the Finance Department. We also carry liability insurance covering your property, and our technicians are trained to handle the steep slopes common in the hills around Wavecrest.
Yes, but we take extra care. From March through August, cliff swallows nesting under eaves and docks at Pillar Point Harbor are protected under the Migratory Bird Treaty Act. We avoid disturbing active nests and use soft brushes and non-toxic cleaners near known roosting areas, ensuring compliance while keeping your windows clear.
