Why 95391 roofs are priced by slope area, not house size
Roof cleaning in Mountain House is quoted on measured slope area, which on these hip-heavy village plans is often larger than the home's floor area.
The tile roofs used across Mountain House are mostly low-to-moderate pitch hips with several planes. A 1,900-square-foot single-story plan in Hansen can carry well over 2,000 square feet of actual slope once the garage return and entry porch are counted.
That is why a phone quote based on floor area tends to come in low. Exterior Prime professionals measure planes from the ground with a laser and confirm the count from the eave, so the $0.55 rate is applied to real area.
Pitch is the second adjustment. Anything steep enough to need rope access carries $0.10 per square foot, which on Mountain House stock usually applies to the taller Bethany and Cordes two-story elevations rather than the single-story plans.

What the dark streaking on Mountain House tile actually is
The black vertical staining on 95391 roofs is gleocapsa, a moisture-holding cyanobacteria, and it comes off chemically rather than by pressure.
It appears first on north-facing slopes and under the shade of the maturing street trees in the older villages, because those are the surfaces that stay damp longest after tule fog and winter rain. From the street it reads as dirt; up close it is a living film with a grip on the tile texture.
Pressure does not solve it. Blasting tile strips the surface paste, shortens the tile's life and can drive water under the courses, and the stain returns fast because the organism's root layer is still in place. Soft washing treats it, waits, and rinses at low pressure.
Timing changes the price. Light streaking clears in one application. Established lichen — the crusty pale spots, common on the oldest Mountain House blocks — carries the $0.05 per square foot surcharge because it needs treatment, dwell time and a second pass.

Worked Mountain House roof totals
At 95391 rates, a 1,000-square-foot roof is $550, a 1,400-square-foot roof is $770 and a 2,000-square-foot roof is $1,100 before adjustments.
Add steep pitch to that 2,000-square-foot example and it becomes $1,300. Add heavy lichen instead and it is $1,200. Both adjustments together put it at $1,400, which is the top of what an ordinary Mountain House residential tile roof reaches.
Gutters are the natural pairing, because whatever comes off the roof lands in them. A 160-foot two-story gutter clean at $1.60 per foot is $256 on its own; the Gutter Combo bundle prices the roof and gutters together at $840.
The largest package worth knowing is Total Exterior at $1,197, which covers house wash, roof, driveway and gutters — $280 less than the same four services bought separately at 95391 rates.

Access and safety on Mountain House tile
Concrete tile can be walked only where the battens support it, which is why Mountain House roof work is done from the eave and from planned foot paths.
A cracked tile rarely leaks immediately. It leaks in the first sustained November storm, months after the visit, which is exactly the situation homeowners cannot easily attribute. Exterior Prime professionals map the walkable lines before stepping onto a 95391 roof and rinse the rest from ladders and extension wands.
Solar complicates it further, and Mountain House has a lot of solar. Panels cannot be walked, cannot be pried at, and change how water drains off the slope. Roof washing on a solar home is planned around the array and the panels are rinsed as part of the same visit rather than left streaked.
Downspout protection matters on these lots. Loosened organic matter has to be caught rather than flushed into the storm system, so gutters are cleared as part of any Mountain House roof job whether or not gutter cleaning was purchased.
