Roof cleaning
Those black streaks come off without touching the shingles.
A soft wash and the right solution. The shingles get zero pressure, so the granules stay on and the roof keeps its years.
Nothing here was scrubbed or pressure washed. Shingles shed their granules under pressure, and the granules are the part doing the work. The growth gets treated and rinsed, so the roof keeps the years it has left.
The black streaks are alive
Those dark stripes running down a shingle roof are not dirt and they are not a stain in the usual sense. They are a growth, and the reason they run downward is that rain carries them down the slope.
That matters for how they come off. You cannot scrub a roof and you certainly cannot pressure wash one. Shingles are coated in granules, and that granule layer is what protects the shingle from the sun. Put pressure on it and the granules come off in the runoff, which takes years off a roof that was fine before you started.
So the pressure stays off entirely. The work is a cleaning solution, applied and given time, and a rinse. The same principle as the siding, taken further, because a roof is less forgiving than a wall.
Same roof, same ridge
BeforeAfter Same ridge, same spot. Nothing was replaced, resurfaced or painted. The granules are still where they should be.
Good to know before I come out
- I'll tell you honestly whether it's worth doing. If a roof is near the end of its life, that money is better spent on the replacement, and I'll say so.
- Cleaning takes the growth off. If I spot a lifted shingle or a flashing issue while I'm up there, I'll show you so your roofer can take a look.
- It pairs with a house wash. Doing both on one visit is less setup than two, so it costs less than booking them apart.
Questions I get asked
Will this damage my shingles?
Not the way I do it. Damage comes from pointing pressure at a roof, which strips the granule layer. My roof cleaning uses zero pressure. The solution does the work and then it gets rinsed.
What are the black streaks?
A growth rather than dirt, which is why they run down the slope and why rinsing alone does not shift them. They need the right solution and time to work.
Can you do the roof and the house together?
Yes, and it is the sensible way to book it. Setup is most of the overhead on a small job, so both on one visit costs less than two trips.
What if you find damage up there?
Repairs are a roofer's job. If I see a lifted shingle, loose flashing or a soft spot, I'll photograph it and show you so you can get it looked at.
Ready for a price?
A photo from the ground, or from an upstairs window, tells me most of what I need.
