Roofing Contractor
in Mountain View, CA
Old Mountain View Craftsmans, Monta Loma Eichlers and office roofs near Shoreline all get the same careful work from Keith Roofing Company. We have been a family-owned roofer since 1952, carry an A+ BBB accreditation, and work under California license #1118418.
Mountain View's Trusted
Local Roofer
Mountain View is a city of contrasts — and so is Mountain View roofing. Old Mountain View, dating to the 1860s, has Victorian cottages, historic Craftsmans, and heritage homes where preservation and architectural sensitivity are primary concerns. Meanwhile, the Shoreline and North Bayshore tech corridor has modern office buildings, mid-rise commercial, and cutting-edge construction where cutting-edge flat-roof systems are standard.
The city has been incorporated since 1902, and its Community Development Department takes Title 24 energy rules seriously. Cool-roof requirements apply to most re-roofs and we spec compliant materials by default. Two different roofing markets in one city — and we work both. From historic Old Mountain View Craftsman shake-to-composition conversions to North Bayshore office-park single-ply installations, our Mountain View portfolio spans the full range. Our familiarity with Mountain View's preservation requirements and the tech corridor's commercial operational standards makes us a natural fit for both.
What this means for you: Owners of older cottages and Craftsmans in Old Mountain View get advice on materials that suit the house and won't cause trouble in a historic review. Newer homes get algae-resistant shingles that stay clean through the damp months, and commercial clients near Shoreline and North Bayshore get flat-roof work scheduled around tenants who can't shut down for a week.
What We See on
Mountain View Roofs
Old Mountain View cottages, postwar ranches and Bayshore office roofs each wear out differently. This is what we usually find when we inspect them.
Residential: architectural asphalt shingle is dominant on mid-century and newer homes; concrete tile is common on custom and Mediterranean-style homes; and cedar-shake-converted roofs on historic Old Mountain View homes typically need upgrading to modern Class A composition. Commercial/institutional: single-ply and modified bitumen dominate flat-roof work for the Shoreline and North Bayshore tech corridor. Cool-roof requirements (Title 24) are strictly enforced and affect most re-roofs.
Title 24 Cool-Roof Enforcement
Mountain View strictly enforces Title 24 cool-roof rules — we spec compliant materials for every re-roof as a default.
Historic Old Mountain View Preservation
Homes in Old Mountain View may be subject to historic preservation review — material and color choices can require approval.
Foggy-Zone Roof Deterioration
Mountain View's high fog exposure accelerates algae growth on north-facing roof slopes — algae-resistant shingle formulations are worth the upgrade.
Shoreline/Bayshore Commercial Demand
Tech corridor flat-roof work is constant — new builds, tenant improvements, and system replacements on maturing office stock.
Mountain View's Specialty: Algae-Resistant Shingle & Tech Corridor Commercial
Why This Material Works Here
Mountain View's notable fog exposure — particularly in areas closer to the Bay and in shaded tree-canopy neighborhoods — creates ongoing algae and moss growth on roof surfaces. Dark streaks on north-facing shingle roofs are a visual indicator of algae colonies (gloeocapsa magma) that feed on shingle granules over time. Algae-resistant shingle formulations with copper-infused granules address this directly.
Technical Installation Approach
For residential work, we specify algae-resistant shingles as a default in Mountain View: CertainTeed Landmark with StreakFighter (10-year algae warranty), GAF Timberline HDZ with StainGuard Plus (25-year algae warranty), or Owens Corning TruDefinition Duration with StreakGuard (limited lifetime algae warranty). These carry a modest premium over non-algae-resistant equivalents but deliver substantial long-term aesthetic benefit in Mountain View's climate.
For Old Mountain View historic preservation work, Class A composition with shake-look profile replaces original cedar shake — maintaining historic aesthetic while meeting modern fire code. We use CertainTeed Presidential Shake or GAF Grand Sequoia profiles that approximate original wood-shake visual character.
Commercial work in the Shoreline and North Bayshore corridors uses single-ply systems meeting Title 24 cool-roof requirements — typically white fleece-backed mechanically-fastened membrane from Carlisle, GAF, or Firestone with 20-30 year warranties.
Expected Longevity & Value
Algae-resistant shingles deliver standard 25-30 year service life with substantially cleaner appearance throughout. Historic-compatible composition lasts 30+ years while meeting modern fire code. On commercial buildings, a single-ply membrane typically carries a 20-30 year warranty and keeps the building energy-compliant for as long as it lasts.
Mountain View's Climate
and Your Roof
Mountain View's damp mornings and mild afternoons are easy on people but not always on shingles. Here is how we plan for them.
Summer Heat & UV
Mountain View summers are mild — 78-85°F typical highs thanks to strong Bay breeze influence. Less UV-driven degradation than inland cities.
Winter Rainfall
Rain comes mostly in winter, and the big atmospheric-river storms are what push water under tired flashing on older homes and into ponded spots on flat commercial roofs.
Fog & Fire Exposure
High fog exposure, especially morning marine layer intrusion through spring and summer. Low wildfire risk. Algae and moss growth on north-facing and shaded slopes is common — algae-resistant materials are strongly recommended.
Practical Implications
Mountain View roofing priorities: algae-resistant material selection (high fog = high algae), Title 24 cool-roof compliance (strictly enforced), preservation-compatible materials for Old Mountain View historic work, and commercial expertise for the Shoreline and North Bayshore corridors.

How We Handle Roofing
in Mountain View
Preservation Review (When Applicable)
For homes in Old Mountain View's historic conservation areas, we verify preservation status and prepare documentation for City review. This adds time to the schedule but ensures compliance.

Installation follows manufacturer spec plus Mountain View code requirements. Photo documentation supports warranty registration, permit close-out, and any future preservation-related questions.
