Tile Roof Cleaning in Modesto, CA
Concrete tile roofs, standard across Modesto's newer subdivisions, get cleaned with a no-pressure soft wash and as little foot traffic as possible, because tile cracks under both blasting and boots. The soft wash kills the algae, moss, and lichen and restores the tile color safely. Call (209) 624-6249 for a free written quote.
Tile's two enemies: pressure and boots
Concrete tile is durable against weather and fragile against point loads. A pressure washer stream can crack tiles outright and blasts off the pigmented surface layer, leaving pale scars. A careless boot does the same damage one step at a time, and every cracked tile is a future leak. Any roof cleaner who plans to walk your tile field dragging a pressure wand is offering to damage your roof for money.
How we work a tile roof
We soft wash from ladders, ridge lines, and walk pads, applying the cleaning solution with reach equipment so the field of tile carries as little weight as possible. The sodium-hypochlorite-based solution kills the black algae film, the moss padding in the tile channels, and the lichen crusts, then everything rinses or weathers off gently. Broken tiles we find along the way get flagged to you with photos, since catching them early is cheap.
Why northeast Modesto roofs streak
The tile subdivisions built across north and northeast Modesto face the same Tule fog winters as everything else in the valley, and tile's porous surface holds moisture well enough to feed heavy algae on north slopes. Orchard dust settles into the tile texture and feeds the film. Cleaned and optionally sealed, tile sheds this cycle for years, and the color change after a proper wash is dramatic, often a full shade lighter.
Questions We Actually Get
Can you pressure wash a tile roof?
No one should. Pressure cracks tile and strips its colored surface. Soft washing with minimal foot traffic is the correct method, full stop.
Will anyone walk on my tile roof?
As little as physically possible. We work from ladders, ridges, and pads with reach equipment. Where a step is unavoidable, it lands where tile carries load best.
What if you find broken tiles?
We photograph and flag them for you. Cracked tiles are future leaks, and knowing about them while repair is cheap is part of the value of the visit.
How much better will my tile roof look?
Usually dramatically, often a full shade lighter once the algae film and dust are gone. The before-and-after on Modesto tile is some of the most striking work we do.
