Roof Cleaning in Farmers Branch, TX 75234
Those black streaks are algae, not stains. Soft washed off without a pressure washer near your shingles.
Roof cleaning in Farmers Branch, TX
Across Marsh Lane from us. Mid-century brick ranches with wide driveways and a lot of shaded concrete.
Farmers Branch is mostly 1950s–70s brick ranch with wide driveways, and the roofs here get the same thing every North Texas roof gets: black streaks running down the north-facing slopes. That's not dirt and it isn't a stain. It's Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler in asphalt shingles. It's alive, which is why it spreads downward and why rinsing it accomplishes nothing.
Never pressure wash a roof
This is the whole page. Shingles are coated in ceramic granules — that layer is what blocks UV and makes the roof last. Pressure blasts them off. The roof looks great for a season and then ages fast, and most manufacturer warranties are void the moment a pressure washer touches them. If anyone in Farmers Branch offers to pressure wash your roof, that's the end of the conversation.
Soft washing is the method
Barely more than hose pressure, with a solution that kills the organism instead of knocking it off. It's what the shingle manufacturers themselves specify. The streaks release over the following days rather than instantly — that's it working.
It isn't only cosmetic
The organism holds moisture against the shingle and eats its filler. Left alone it genuinely shortens roof life. Given what soft old mortar joints does around here, it's the cheapest thing you can do for a roof you'd like to keep.
Why we quote Farmers Branch jobs in person
Square footage gets you a baseline and nothing more. Condition is what moves the number, and condition is exactly what nobody can assess over the phone. In Farmers Branch we're looking specifically at soft old mortar joints, original wood fascia, and long stretches of shaded concrete. Finding it at the estimate means it's in the written number. Finding it mid-job means a conversation neither of us enjoys.
What to ask anyone bidding roof cleaning in Farmers Branch
Ask what pressure they'll use, surface by surface. If they give you one number for the whole property, they're going to damage something — concrete takes 3,000 PSI and siding takes about 500. Ask whether flat concrete gets a surface cleaner or a wand; a wand is what leaves stripes. And ask for the insurance certificate, which any legitimate operator sends without being chased.
Getting on the schedule
We're based in Addison, so Farmers Branch is a short drive and coming back isn't a production. Spring is the busy stretch — on homes this age we almost always find something a phone quote would have missed. Call and we'll tell you honestly where the calendar is, including if we're too far out to help on your timeline.
Why we're not the cheapest quote in Farmers Branch
We won't be. The material cost between a cheap wash and a good one is small; the difference is knowing what not to blast, using the right solution instead of just more pressure, and taking the time to protect what stays. An operator bidding well under everyone else is planning to point one setting at everything and be gone before it shows.
If price is the deciding factor, we understand — there are cheaper operators in Farmers Branch. What we'd ask is that you get their pressure answer in writing first, so you're comparing the same job.
Pressure alone loses to anything living
Worth repeating because it's the thing that costs people the most money. The grey-green film on shaded concrete and the black streaks on north-facing roofs aren't dirt — they're organisms. Pressure knocks the visible layer off and leaves the rest, which regrows within weeks. A solution that actually kills it is the difference between washing annually and fighting the same battle twice a year forever.
This is also why the cheapest quote often costs more. If it comes back in a month, you didn't save anything.
What we protect while we work
Plants get watered down before we start, so they aren't drinking anything concentrated, and rinsed after. Fixtures, outlets, and vents get covered. Pets stay inside. If there's something in your yard you're precious about, tell us at the estimate — we'd rather plan around it than apologize for it.
Free estimates, in Farmers Branch and everywhere else we work
Free, in person, no pressure. We look at the actual surfaces, tell you what will come out and what won't, and give you a written number. If we can't get the result you're after, we'll say so rather than take the job and hope. That happens more than you'd think, and it's why people call us back.
