A summer of ag dust and a winter of tule fog is what puts the black streaks up there. We kill it at the root on tile, shingle and metal, with no pressure on the roof at all.

Or Call Us NowQuick answer. Roof cleaning in Tulare, CA has to fight an unusually good food supply for algae, because organic dust off the dairies, feed storage and crop ground settles on the roof through summer and then tule fog parks over this stretch of the Valley long enough for the growth to take hold. Tulare also has more metal roofing than a typical Valley town on its shops, barns and ag structures, and metal never gets pressure from us either, only a soft wash and a controlled rinse so nothing is driven under a seam or a lap. On residential tile we walk the lower third of each tile where the batten and the course below carry the load, which is the difference between a clean roof and next winter's hairline leak, and the estimate is free and specific to your roof.
Those black streaks are living algae, and in Tulare they have an unusually good food supply sitting on the roof all summer.
Two things local to Tulare speed the whole process up. The first is the organic dust coming off the dairies, feed storage and crop ground, which settles on the roof through summer and gives the algae something to work with. The second is tule fog, which parks over this stretch of the Valley for days at a time and keeps the surface damp long enough for it to take hold. Dust arrives in September, growth starts in January.
Tulare also has more metal roofing than a typical Valley town, because of the shops, barns and ag structures. Metal grows a different version of the problem. The organic film holds moisture against the panel and against the fastener washers, and that is exactly where corrosion starts. Metal never gets pressure from us either. It gets a soft wash and a controlled rinse so nothing is driven under a seam or a lap.
On residential tile we walk the lower third of each tile, where the batten and the course below actually carry the load. Step in the middle of a concrete tile and you get a hairline crack that becomes next winter's leak. That is the single most common way a roof gets damaged during a cleaning, and it usually gets blamed on the weather.
On composition shingle, pressure blasts the granules off, and the granules are the shingle's sun protection. Strip them and the roof ages fast in a Valley summer. Soft washing is low pressure plus dwell time, so the solution kills the organism rather than knocking the top layer loose, and the roof stays clean substantially longer as a result.
One question sorts that results page fast. Ask whether they put pressure on the roof, and if the answer is yes, move on.
A pressure-washed roof looks better for a season and is worse off for it. The granules or the tile glaze are gone, water has been pushed places it should not be, and the algae is still alive because nothing killed it.

A roof cleaning is worth paying for only if the growth is dead when we leave. That takes chemistry, technique and staying off the wrong part of the tile.
Access is the expensive part of roof work. Everything else above head height is much cheaper on the same visit.
Fog covers the whole county at once, so we run roof routes across Tulare and Kings counties through the spring.
