Keith Roofing Company has been covering Mountain View roofs for decades — residential and commercial, tile and shingle, repair and replacement. Family-owned since 1952. BBB A+ Accredited. California Licensed #1118418.
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 itself has been incorporated since 1902 and operates its own Community Development Department with a notably strict Title 24 energy enforcement. 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 TPO 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: When you call Keith Roofing for your Mountain View home or business, you're not getting a generic quote from a roofer who works everywhere and specializes nowhere. You're getting contractors who know this specific market — the typical failure modes, the dominant roof systems, the permit process, the HOA and preservation rules, and the pricing that makes sense for your property type and neighborhood.
Decades of working this specific market means we know the common failure modes, the dominant roof systems, and what to look for at estimate.
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: TPO 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.
Mountain View strictly enforces Title 24 cool-roof rules — we spec compliant materials for every re-roof as a default.
Homes in Old Mountain View may be subject to historic preservation review — material and color choices can require approval.
Mountain View's high fog exposure accelerates algae growth on north-facing roof slopes — algae-resistant shingle formulations are worth the upgrade.
Tech corridor flat-roof work is constant — new builds, tenant improvements, and system replacements on maturing office stock.
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.
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 TPO 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.
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. Commercial TPO delivers 20-30 year warranted service life with energy compliance for the life of the system.
Roofing materials and installation techniques should reflect local climate realities — not generic specifications. Here's what Mountain View's specific weather patterns mean for your roof.
Mountain View summers are mild — 78-85°F typical highs thanks to strong Bay breeze influence. Less UV-driven degradation than inland cities.
Typical South Bay rainfall — 15-18 inches annually. Atmospheric-river events are the primary flat-roof stress scenario.
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.
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.
Historic Craftsmans, Victorian cottages, and heritage homes — preservation rules apply.
Mid-century ranch homes — straightforward shingle re-roof market.
Newer residential and townhomes.
Commercial flat-roof systems for tech corridor.
Residential with a mix of 1950s ranches and newer custom homes.
Eichler-era homes with distinctive low-slope roof systems.
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.
For Mountain View residential work, we default to algae-resistant shingle formulations. Homeowners can opt for non-algae-resistant if budget dictates, but we'll explain the long-term implications in Mountain View's climate.
Mountain View Community Development strictly enforces Title 24 cool-roof requirements. We prepare NFRC ratings, alternative compliance documentation, and product specification sheets for the permit application.
Installation follows manufacturer spec plus Mountain View code requirements. Photo documentation supports warranty registration, permit close-out, and any future preservation-related questions.
For Old Mountain View historic homes, we handle the preservation review, material selection, and installation with the care the homes deserve. Shake-to-composition conversions that maintain historic aesthetic are a specialty.
We know how Mountain View's fog climate treats different shingle formulations over 10, 20, and 30-year timeframes. Material recommendations reflect actual Mountain View performance data, not manufacturer marketing.
North Bayshore and Shoreline commercial property work is a regular part of our business. Property manager coordination, tenant notification, energy compliance documentation — standard commercial practice.
Mountain View is stricter on Title 24 enforcement than most cities. We stay current on compliance requirements and alternative paths, reducing permit review time and avoiding costly inspection failures.

An 1898 Queen Anne Victorian in Old Mountain View had original cedar shake that had been replaced with 3-tab composition shingle in 1987. At 36 years old, the 3-tab was failing and the home was subject to historic preservation review. We proposed a CertainTeed Presidential Shake TL architectural shingle in a charcoal-gray profile that mirrors the original cedar shake aesthetic. The project required preservation-board approval (5-week review), structural assessment of the original decking (skip-sheathing that had to be overlaid with solid sheathing), full tear-off of existing composition, new underlayment with ice/water shield at valleys, and Presidential Shake TL installation with matching ridge and hip work. Final inspection passed preservation review with commendation for aesthetic compatibility. Homeowner received 50-year CertainTeed SureStart PLUS warranty plus restored historic character.
