Helping Tigard Homes Stay Clean Through Every Oregon Season
Roof moss in Tigard does not show up the same way from one neighborhood to the next. On the shaded slopes of Bull Mountain, roofs tucked under Douglas firs and leafy tree cover can develop thick moss mats, especially on north-facing sides. Down near the Fanno Creek corridor in Metzger, older ranch-style homes with lower-pitch roofs often hold moisture longer under mature trees. Even in newer areas like River Terrace, roofs with more sun exposure can start showing dark algae streaks as the years go by.
At 4 Seasons Softwash, we help homeowners protect their roofs with careful, professional soft washing that is tough on moss, algae, and lichen while being mindful of the roofing material. We bring a detail-oriented approach to every job, taking time to understand the roof’s condition before recommending the right cleaning solution.
Call us at (971) 434-7355 for a free estimate. We will look at the roof in person, assess the actual conditions, and provide a clear quote based on what your property really needs.
Roof Types We Handle Across Tigard
We clean the full range of roof materials across Tigard’s residential and commercial properties, adjusting our method to match the surface.
A soft-bristle brush clears debris, then biodegradable detergent kills moss, algae, and lichen without high pressure. Moss releases naturally over four to six months through wind and rain. Asphalt shingle is the default residential roof material citywide, from architectural shingle on Bull Mountain’s larger-lot homes to standard three-tab on Summerlake and River Terrace subdivisions.
Biodegradable detergent is applied and rinsed gently. The soft-wash approach prevents cracking or chipping on tile surfaces.
Detergent is applied and gently rinsed without brushing. Algae streaking develops on metal panels under canopy shade, even though moss does not grip metal the way it grips shingle. Metal roofs are scattered on newer River Terrace builds and some commercial structures across the city.
TPO (Thermoplastic Polyolefin) and membrane roofs on commercial buildings are cleaned with the same soft-wash chemistry, applied flat, and rinsed without mechanical agitation. Commercial structures along the Hall Boulevard corridor commonly carry these flat membrane roofs.
Serving Tigard Homes and Commercial Properties
Tigard homes face a wide range of roof conditions, from the steeper roofs on Bull Mountain to the shaded, low-pitch ranch homes in Metzger. Our soft-wash roof cleaning is built for those local challenges, removing moss, algae, and buildup without harsh pressure that can damage shingles.
Before any treatment begins, we provide a free roof inspection to check vents, roof jacks, ridge caps, and overall roof condition. Our SoftWash Systems-certified crew uses an ARMA-compliant cleaning method and OSHA-approved fall protection on every residential job.
Every residential roof cleaning includes a five-year warranty, and because moss grows year-round in the Pacific Northwest, we offer service in every season, not just summer.
Commercial roof cleaning covers TPO/membrane flat roofs and metal-roofed structures such as storefronts, mixed-use buildings, and commercial properties along the Hall Boulevard corridor and near Bridgeport Village. We coordinate with the decision-maker through an in-person site walkthrough before quoting, and our crew works around open business hours with A-frame caution signage. After-hours scheduling is available for sites that need it. The same soft-wash method and five-year warranty apply to every commercial roof.

Give Your Roof the Care It Deserves
What to Expect from Your Tigard Roof Cleaning
Reach Out, and We Respond Fast
Call or submit the website form. Our goal is a response within sixty seconds. We start by understanding the roof type, the property layout, and any specific concerns you have.
Free In-Person Estimate
We schedule an in-person visit so we can see the roof directly. That lets us evaluate square footage, pitch, material condition, and buildup severity before quoting.
Pricing Tied to Real Conditions
Your quote reflects the actual state of the roof: square footage, pitch, shingle type, moss severity, and crew access requirements. No flat-rate guessing, no one-size-fits-all packages.
Booking Confirmation and Reminders
Once you approve the estimate, the job goes on the schedule through HouseCall Pro. You receive a reminder one week out and another two days before the appointment.
Inspection and Soft-Wash Cleaning
Before we clean, we inspect your AF-50 vents, B vents (roof jacks), ridge caps, and the overall integrity of the roof. If we find loose shingles, flashing issues, or signs of damage, we let you know up front. Then our crew applies a soft-bristle brush on asphalt and tile (rinse-only on metal), followed by biodegradable detergent that kills and inhibits moss, algae, and lichen. OSHA-approved fall protection and ladders are in place throughout. Tigard’s pitch variation means the crew adjusts access on every job, from Bull Mountain’s steeper slopes down to Metzger’s low-pitch ranch-style roofs along the Fanno Creek corridor.
Walkthrough and Follow-Up
Our crew walks the completed work with you, reviews anything found during the inspection, and makes sure you are satisfied before packing up. Moss releases naturally over four to six months through wind and rain after treatment, and the five-year warranty starts at that point. A Google review request follows the visit.
Our Comprehensive Roof Cleaning Pricing
Roof cleaning in Tigard typically begins around $600, with larger or more complex projects priced higher based on the details of the roof. Luxury properties, difficult access, steep pitches, heavy moss growth, or unusually large roof systems can increase the cost significantly, with some high-end projects reaching $25,000 or more.
We do not use one-size-fits-all pricing. Every estimate is based on what your roof actually needs, including its size, slope, material, access, and the level of buildup. Your quote is always free and completed in person, so we can give you an accurate price before any work begins.
Discounts available:
- Bundle four or more services and save 5 to 10% off the full job.
- Pair house washing with window cleaning for a discounted window cleaning rate.
- Use code “25-OFF” for $25 off when booking two or more services.
Service Plans
Our service plans set a recurring cleaning schedule that matches Pacific Northwest moss and debris pressure, so your roof stays ahead of regrowth instead of reacting to it. Three tiers are available:
Twice-a-Year Service
Two scheduled cleanings per year help keep exterior buildup from getting ahead of the property. This plan is ideal for homeowners who want consistent upkeep without over-cleaning, and it includes 10% off the services in the plan.
Quarterly Service
Quarterly service keeps moss, algae, grime, and curb-appeal issues under control through all four seasons. It works well for shaded homes, properties with heavy tree coverage, and commercial spaces that need a dependable appearance, with 15% off included services.
Monthly Service
Monthly service gives your property the most consistent care throughout the year. It is best for commercial buildings, storefronts, and highly visible residential properties that need to stay clean month after month, with 20% off included services.
