Merced Window Cleaning serves residential homeowners throughout Merced, CA, matching the cleaning method to what the roof actually needs. The two types we work with most are asphalt shingle and tile, and each calls for a different approach: soft washing for most situations, and pressure washing reserved for tile when the homeowner wants a same-day result. Roof buildup in the Merced area tends to show up on the north-facing side of a home first, though the west and east sides develop the same problems. Cooler-season moisture, winter fog, and valley dust all contribute to moss, lichen, and organic debris settling in over time; left in place, that material keeps building until it washes into the gutters.
We offer two roof-cleaning methods depending on the roof type and the homeowner’s goals. Soft washing is the standard approach for asphalt shingles and works well for tile too. Pressure washing is reserved for tile roofs when the homeowner wants visible results the same day. We commonly recommend pairing roof cleaning with gutter cleaning in a single visit, and we make sure you understand the plan and what to expect before we start anything.
Every estimate is done in person because roof size, condition, and cleaning requirements vary too much for a reliable phone quote. Soft wash roof cleaning starts at about $350 for smaller jobs and typically falls between $350 to $750, with pricing based on a factor of square footage × 0.18. Pressure washing for tile roofs runs from about $500 to $1,500, using a factor of square footage × 0.25.
What moves the number up or down includes:
On the scheduling side, a soft wash only takes at least 2 hours, a soft wash with gutters runs 2–3 hours, and pressure washing a tile roof typically takes 4–6 hours. If you have a tile roof, we walk you through both method options at the estimate so you can decide what fits your goals and your schedule.
Each job is priced on its own merits, and we keep that straightforward from the estimate through the invoice.
Asphalt shingle and tile are the two roof types we encounter most in this market. We do not position our service around metal, clay, or slate since those materials are not common in the areas we serve. The cleaning method we use depends on the roof material and what the homeowner is trying to accomplish. Where chemical treatment is involved, we use a bleach and soft wash solution.
Asphalt shingle roofs are always soft washed. The surface layer of a shingle is designed to protect the material underneath, and pressure washing would damage or destroy it. On a shingle roof, we clear debris, scrub off large moss pieces with a nylon brush on an extension pole, and then apply the solution. This approach cleans the roof without putting stress on the material. If another company is suggesting pressure washing for your shingles, that is not something we practice or support.
Tile roofs can be cleaned with either method, and the right choice depends on the condition of the roof and what you are trying to accomplish. Pressure washing delivers a same-day result if that is what you are after. Soft washing works well too, but a soft-washed tile roof can still look yellow for 6 to 12 months while the treatment continues working, and that is an expectation we cover at the estimate to avoid surprises. We also want you to know that about 90 to 95 percent of tile roofs we work on already have some pre-existing cracked tiles before we arrive. We photograph what we find before touching anything, walk you through it, and choose the method based on condition, pitch, and safety.
We do not apply one approach to every roof. Asphalt shingles require soft washing. Tile roofs offer more flexibility, and we help you weigh soft washing against pressure washing based on your timeline and what the roof can handle. Knowing the difference between materials and respecting what each one needs is how we protect your roof rather than just clean it.
Before cleaning starts, we take a close look at the roof for visible issues. If we find cracked tiles or other damage, we photograph those areas and bring them to your attention before work begins. If the damage is severe enough that cleaning is unlikely to help, we say so upfront. After the job, we can point you toward a roofing company if repair work is needed. This step protects you and makes sure anything present before we arrive is documented and discussed before we do anything.
A soft wash solution that is not managed carefully can affect plants, gutter exteriors, and surrounding surfaces. We take specific steps on every job to prevent that. Before applying any solution, we water the landscaping and pre-wet the gutter exteriors. We set up the downspouts to capture solution runoff during the work. When the cleaning is complete, we water the plants again, wet the gutters again, and remove all captured materials from the downspouts before we leave. Responsible runoff handling matters in Merced County, where keeping pollutants out of stormwater systems is taken seriously, and our process reflects that.
We carry liability insurance up to $1 million. We use ladder stabilizers on every roof job to avoid denting gutters and for technician safety. We use a harness when conditions call for it, and on roofs that are too steep to walk safely we handle the work from the ladder rather than put anyone in an unnecessary position. The question homeowners often have but do not always ask is whether they can trust a crew on their roof, and we think our approach to safety and insurance gives a clear answer.
Roof cleaning is different from most exterior services because you usually cannot clearly see the results from the ground. We send before-and-after photos for every roof cleaning job so you have a clear record of what was there and what we did. That documentation also comes in handy when you need to share cleaning history with an HOA, an insurance carrier, or for your own property records.
We schedule in-person estimates for all roof cleaning work, and from there the process stays organized. You receive reminder messages before the appointment, a text when the crew is on the way, and an electronic invoice and receipt after the job is done. If something about the result does not meet your expectations, we review the concern and come back to handle any needed touch-ups.
Merced Window Cleaning has earned more than 300 reviews on Google and received the Angi Super Service Award in 2023. We hire carefully and train our team to represent the business the right way. We have been serving this community since 2022 and plan to stay.
Around the three-year mark after a roof cleaning, we reach back out with a letter or a call. We offer a free inspection to see how the roof is holding up, and if a maintenance treatment is needed at that point, we offer it at a preferred rate. This is how we think about long-term roof care for the homeowners we work with, not a one-and-done transaction.
All roof cleaning estimates are done in person at the property. When you reach out, we set up an estimate appointment, and if you approve the quote, we schedule the service. From there you receive reminder messages ahead of the appointment and a text when the crew is heading your way. The estimate visit is also where we cover which cleaning method fits your roof, what results to realistically expect, and whether it makes sense to include gutter cleaning at the same time.
When the crew arrives, the first order of business is a thorough visual inspection before any equipment is set up. We look for cracked tiles and any other visible issues, photograph what we find, and let you know what we saw. If the damage is severe enough that cleaning is not the right next step, we say so before starting anything. Safety setup runs alongside the inspection: ladder stabilizers are used on every job, a harness goes on when the roof conditions call for it, and on roofs that are too steep to walk we work from the ladder. We only go up on a roof when it is walkable and safe to do so.
Before any solution goes on the roof, we prepare the surface. The ladder stabilizer goes up, and we head onto the roof with a leaf blower to clear loose debris. If there is significant moss buildup, we scrub off the largest pieces with a nylon brush on an extension pole and blow the loosened material away. Debris that ends up in the gutters gets picked up as part of this step. If gutter cleaning is part of the visit, we often take care of the gutters first so that debris from the roof work does not land in freshly cleared gutters.
The treatment method depends entirely on what we are working with. Asphalt shingle roofs are soft washed only. For tile roofs, we default to soft washing or use pressure washing when that is the better fit for your goals and the roof’s condition. For the soft wash sequence, we set up the downspouts to capture runoff, water the plants and landscaping, pre-wet the gutter exterior, connect the soft wash system and hoses, and apply the bleach and soft wash solution from the top of the roof down to the bottom. Pressure washing for tile roofs is used when the homeowner wants a same-day visual result and the roof is in a condition where that method is appropriate; pitch, condition, and safety all factor into that call.
Once the cleaning is done, we put the system away and take care of the property. That means watering the plants again, wetting the gutters again, and collecting all captured materials from the downspouts before we leave. You receive photos of any issues we noted and photos of the completed work; before-and-after pictures are standard for every roof cleaning job. Payment is accepted by cash, check, card, or Venmo, and card payments carry a 3% fee. Invoices and receipts are delivered electronically if you have email on file. If anything falls short of your expectations, let us know and we will come back to handle any needed adjustments.
We back our roof cleaning work with a two-year guarantee. For tile roofs that have been soft washed, if lichen is still visible at the 12-month mark, call us and we will return for spot treatment if needed. That two-year roof cleaning warranty is our commitment to standing behind the work after the crew has left. We also warrant your satisfaction: if the results are not what you expected, we will review the concern and come back to handle any touch-up or adjustment that is warranted. Pre-existing damage is documented before we start, discussed with you before work begins, and we can refer a roofer afterward if repair work is needed. Documenting what existed before we arrived protects everyone and keeps expectations clear from the start.
Your roof is one of the most important parts of your home, and keeping it clean isn’t just about appearance, it’s about protection. A dirty, moss-covered roof can lead to serious issues like lifted shingles, cracked tiles, and even leaks that allow water and mold to enter your home. Over time, this damage can significantly shorten your roof’s lifespan and lead to costly repairs or replacements.
In addition, neglecting your roof can hurt your home’s curb appeal and may even put you at risk of a homeowner’s insurance cancellation due to poor maintenance. Regular roof cleaning helps preserve your roof’s integrity, protect your home, and maintain its value.
We offer both soft washing and pressure washing, but the method depends on the roof type. Asphalt shingle roofs are never pressure washed. For tile roofs, pressure washing is an option when the conditions are right and the homeowner wants a fast visible result.
Yes. Pressure washing strips the protective surface layer from asphalt shingles, which is why we do not offer it for that roof type. If another company is suggesting pressure washing for your shingle roof, that is not a method we use or stand behind.
We adjust our pressure washer’s pressure to around 2,000 PSI, which is safe for tile roofs, and we are mindful of how we step on your roof.
We document it before we touch anything. Pre-existing damage gets photographed and discussed with you before cleaning starts. If the roof is in a condition where cleaning is not the right next step, we will say so honestly rather than take your money on a job that is not set up to go well.
Yes, when handled correctly. We water landscaping before and after treatment, pre-wet and rinse gutter exteriors, capture solution runoff at the downspouts during the job, and remove all collected material before we leave. These are standard steps on every roof cleaning job, not optional precautions.
A soft wash only typically takes at least 2 hours. When gutter cleaning is included in the same visit, plan for 2–3 hours. Pressure washing a tile roof is a longer job and most run 4–6 hours.
A tile roof that is pressure washed will look noticeably cleaner the same day. A tile roof that is soft washed can take 6–12 months to fully reflect the cleaned result, since the solution keeps working over time. Asphalt shingle roofs treated with soft washing often look significantly better within 2–3 weeks.
The north-facing side gets less direct sun, which means it stays damp longer after rain and fog. In the Merced area, cooler-season moisture and winter fog patterns keep shaded sections wet enough for moss and organic material to establish. The west and east sides can develop the same buildup for similar reasons, and valley dust gives organic material something to cling to as it settles.
When a roof is cleaned, debris and loosened material naturally work their way toward the gutters. Doing the gutters in the same visit, often first, keeps that material from settling right back in after the roof is cleaned. It is a practical maintenance pairing, not padding the invoice.
Having clogged gutters before treatment causes your gutters to overflow with roof wash solution, which makes a mess on your exterior gutters, patios, and can harm your plants.
Yes, on every roof cleaning job. Roof cleaning is one of the services where that documentation matters most because most homeowners cannot see the roof clearly from the ground. Those records are also useful when sharing cleaning history with an HOA, an insurance carrier, or for your own files.
Yes. A steep tile roof where the homeowner wants pressure washing instead of soft washing is one example where we may decline. Safety, overall condition, and method suitability all determine whether we accept a job, and we would rather pass on a job that is not the right fit than take it on and create problems.
There is no single window that works for everyone, but Merced’s cooler months and winter moisture patterns tend to make roof staining, moss, and buildup most visible. Some homeowners prefer to schedule before the rainy season; others prefer to clear winter accumulation once things dry out in spring. Either timing works well. The most important thing is not letting contamination build up year after year without addressing it.
Not necessarily. We communicate throughout the process, text when on the way, document everything with photos, and send the invoice electronically. Any specific access requirements are confirmed at the estimate so everything is clear before the appointment.
If your roof is showing moss, lichen, or years of discoloration, addressing it sooner protects you from a more serious problem down the road.
