Mountain View Roofing
Residential Roofing Services
We install, repair, and replace asphalt shingle, concrete tile, metal, and low-slope systems across all 12 square miles of the city, working within Title 24 cool roof requirements, the city's Reach Codes, and Mountain View's permit process. Mountain View homes span 1950s Eichler flat roofs in Monta Loma, Spanish-tile bungalows near Castro Street, and newer townhomes off El Camino Real — each demanding a different roofing approach.
Free Written Estimates
A quality roofing contractor believes your estimate should be clear and honest from the beginning. We provide a detailed scope of work so you understand exactly what you're paying for, with no hidden fees or surprises. If unexpected damage is discovered once the old roof is removed, we'll explain the issue, show you the problem, and get your approval before any additional work is performed.
A Company You Can Trust
Choosing a roofing contractor means trusting someone with one of your most important investments. A quality contractor earns that trust by being licensed and insured, communicating clearly, showing up when promised, using experienced installers, and keeping you informed throughout the project. We believe professionalism and accountability shouldn't end when the final payment is made.
Guaranteed Quality Work
A quality roof replacement is about more than putting new shingles on your house. We look for the underlying causes of leaks and pay close attention to vulnerable areas such as flashing, valleys, penetrations, vents, and roof-to-wall transitions. Our goal is to install a complete roofing system correctly the first time, so your new roof protects your home for years to come.
Range Of Services
These are the most frequently requested services from our Mountain View and South Bay Customers
Roof Installation/Replacement
Replacement makes financial sense when repair costs approach a third of a new roof, when granule loss is widespread, or when the deck shows
soft spots. Asphalt roofs in Mountain View generally reach the end of service
between 20 and 28 years, helped by the mild climate but stressed by UV exposure and winter rain cycles.
Roof Repair
Most repair calls we receive in Mountain View involve flashing failures, cracked tiles, damaged pipe boots, or leaks around skylights and solar mounts. Winter storm season from November through March produces the highest volume. The repair of each roof is unique and needs to be thoroughly evaluated so that the issue is solved properly the first time.
Roof Maintenance
Regular roof maintenance helps extend the life of your roof and prevent costly repairs. A quality roofing contractor can inspect for damaged or missing shingles, worn flashing, clogged gutters, leaks, and other potential problems before they become major issues. Routine inspections and timely repairs help keep your roof performing properly and protect your home from water damage.
Emergency Services
Active leaks during a winter storm require response within hours, not days. Our emergency service covers the Mountain View area with same-day dispatch for active water intrusion, wind-lifted roofing, tree impacts, and structural breaches. The immediate objective is stopping water entry. We install reinforced tarps, temporary membrane patches, or plywood dry-in over the affected area, then return for permanent repair once weather allows and materials are staged.
Roof Inspection
We recommend a full inspection every two years, and annually once a roof passes 15 years of service. Our inspections cover field condition, flashing at all penetrations, valley integrity, ridge and hip condition, attic ventilation, sheathing from below where accessible, gutter and downspout function, and fastener condition. Real estate transaction inspections are a significant part
of our Mountain View workload, given the pace of home sales in the area.
Leak Detection & Repair
A stain on the ceiling rarely sits directly under the entry point. Water travels along rafters, sheathing seams, and HVAC ducting before it shows up inside. We trace leaks using moisture meters, infrared thermal imaging, and controlled water testing on suspected penetrations. Common failure points we find in Mountain View: pipe boot flashing, failed mortor on tile roofs, ponding water, and skylight and chimney flashing.
Residential Roofs
Shingle Roofing
Architectural asphalt shingles cover the majority of Mountain View's single-family homes, and for good reason. They handle the Bay Area's wet winters and dry summers without cracking, and they cost less per square than tile or metal. We install laminated shingles from GAF, Owens Corning, and CertainTeed, typically with 30- to 50-year limited warranties.
Tile Roofing
Concrete and clay tile suits the Mediterranean and Spanish Revival homes scattered through Old Mountain View and Cuesta Park. Tile lasts 50 years or more, resists fire — a Class A rating that matters for insurance in California — and reflects heat well in summer. The underlayment beneath the tile is the real waterproofing
layer, and it wears out long before the tile does.
Metal Roofing
Standing seam metal has grown popular on Mountain View's modern remodels and accessory dwelling units. Panels come in Kynar-coated steel or aluminum, carry 40- to 70-year service lives, and pair well with rooftop solar mounting without penetrating the panel. Metal also meets California's cool roof reflectance standards in most factory finishes, which simplifies Title 24 compliance.
Cool Shingles
Title 24, Part 6 of the California Energy Code sets minimum solar reflectance and thermal emittance values for reroofing projects. In Climate Zone 4, which covers Mountain View, steep-slope residential roofs generally need an aging solar reflectance of at least 0.20 and thermal emittance of 0.75 — or a Solar Reflectance Index of 16 or higher. Cool shingles lower attic temperatures by 10 to 20 degrees on hot afternoons, which reduces air conditioning load and slows the aging of roof decking.
Presidential Shingles
Presidential Shake is a luxury laminated shingle that mimics hand-split cedar using a triple-laminated fiberglass construction. It carries a Class A fire rating, a 130 mph wind warranty, and a lifetime limited warranty for the original homeowner. Homeowners in Waverly Park and Blossom Valley often choose it when they want cedar's depth without the maintenance or fire risk.
Flat Roof
Mountain View has one of the higher concentrations of Eichler homes in the Bay Area, and those low-slope roofs need materials built for standing water and minimal pitch. We install TPO, PVC, and modified bitumen systems, along with fluid-applied silicone coatings for roofs that are still structurally sound. Drainage matters more than material choice. We verify scupper and drain placement, add tapered insulation where ponding occurs, and flash every parapet and skylight curb.
Commercial Roofs
TPO Roofing Systems
Thermoplastic polyolefin is the most requested commercial membrane in Mountain View, and for good reason. White TPO reflects roughly 78–80% of solar radiation, which helps buildings meet California Title 24 cool roof requirements without additional coatings. We install TPO in 45, 60, and 80 mil thicknesses, using either mechanically fastened, fully adhered, or ballasted methods depending on
deck type and wind exposure. Seams are hot-air welded, producing a bond that is typically stronger than the membrane itself. This matters during the winter atmospheric river events that bring most of the city's 15 inches of annual rainfall.
EPDM Roofing
Ethylene propylene diene monomer, commonly called rubber roofing, has a service history stretching back to the 1960s. It remains a
practical choice for warehouses, self-storage facilities, and buildings where foot traffic is minimal.
EPDM handles UV exposure and thermal cycling well, and the Bay Area's moderate temperature swings put less stress on the material than inland climates do.
We offer 45, 60, and 90 mil options in fully adhered and mechanically attached configurations.
PVC Roofing Systems
Polyvinyl chloride membrane is our recommendation for restaurants, food processing facilities, and any building where grease, oils, or chemical exhaust reach the roof surface. Mountain View's Castro Street restaurant corridor is a common application. PVC resists animal fats and petroleum byproducts that degrade TPO and EPDM over time. The membrane is also inherently fire resistant.
Like TPO, PVC uses heat-welded seams and reflective white
surfacing that satisfies cool roof standards.
Why We're the Best Roofing Company in Mountain View, CA
We hold a California C-39 roofing license, carry workers' compensation and general liability coverage, and pull permits through the City of Mountain View Building Division for every tear-off and re-roof. Our crews work daily on Eichler low-slope roofs in Monta Loma and Fairmead, Spanish tile in Old Mountain View, and composition shingle on the 1950s tract homes near Cuesta Park.
What sets our work apart:
Roof Replacement Steps
- We follow the same sequence on every project:
- Property protection — tarps over landscaping, plywood against siding, and magnetic sweeps staged for daily cleanup.
- Tear-off— existing layers removed down to the deck, with debris going directly into a dumpster placed on the driveway.
- Deck inspection — we check for dry rot, delamination, and fastener holding power, then replace damaged sheathing at an agreed per-sheet rate.
- Underlayment and flashing — synthetic underlayment, ice and water shield in valleys, and new metal at chimneys, walls, and penetrations.
- Installation— field material applied per manufacturer specification to preserve warranty coverage.
- Ventilation — ridge vents, O'Hagin vents, or turtle vents installed to meet the 1:150 intake-to-exhaust ratio.
- Cleanup and city inspection — final magnet sweep, then we schedule the Building Division inspection and provide you with the signed permit card.
Roofing Services FAQ
Roof repair leads our call volume, particularly leak repairs
discovered after the first significant rainfall between November and March.
Full roof replacement ranks second, with most requests
coming from homes built in the 1950s through 1970s tract developments where
original composition shingle roofs have exceeded their service life.
Other frequent requests include:
- Roof inspections for real estate transactions
- Flat roof and torch-down repair on mid-century modern and Eichler-style homes
- Gutter and downspout replacement
- Skylight flashing repair, common on ranch homes with added skylights
- Solar panel removal and reinstallation during reroofing, given Mountain View's high residential solar adoption
A standard architectural asphalt shingle replacement on a
1,800 to 2,200 square foot home generally runs $14,000 to $24,000,
including tear-off and disposal of the existing layer.
Concrete or clay tile installations typically fall between $25,000
and $45,000, depending on structural reinforcement needs.
Standing seam metal roofing ranges from $28,000 to
$55,000. Flat roof systems using TPO or modified bitumen average $9 to
$16 per square foot installed.
Costs in Mountain View sit above the national average
largely due to Bay Area labor rates, disposal fees, and California Title 24
cool roof compliance requirements.
Minor repairs — replacing a small section of damaged
shingles, resealing a vent boot, or patching a single leak point — usually cost
$450 to $1,200.
Moderate repairs involving flashing replacement around
chimneys or valleys typically range from $1,200 to $3,500.
Larger repairs, such as replacing sheathing damaged by
prolonged water intrusion or reworking a section of flat roof, commonly land
between $3,500 and $8,000.
Emergency tarping after storm damage generally costs $400
to $900, and most roofing inspections in the area run $150 to $400,
often credited toward the repair.
Yes. The City of Mountain View Building Division requires a
permit for reroofing, roof replacement, and most structural roof repairs.
Permits are issued through the Community Development
Department at 500 Castro Street. Reroofing permit fees are typically calculated
based on project valuation, and many straightforward residential reroofs
qualify for over-the-counter issuance.
Key requirements include:
- Maximum of two roofing layers under the California Residential Code — a full
- tear-off is required if two layers already exist
- Title 24 cool roof compliance for low-slope roofs and, in many cases,
- steep-slope roofs, requiring minimum solar reflectance and thermal
- emittance values
- Class A fire rating for roof assemblies
- Inspections including sheathing/nailing inspection before covering and a final inspection.
Homes within designated historic districts or with Historic Resource status may require additional review before material changes are approved. We handle permit applications and inspection scheduling as part of
our projects.
Mountain View's Mediterranean climate brings roughly 15
inches of annual rainfall concentrated in winter, followed by long dry summers
with frequent UV exposure. That pattern favors materials that shed water
efficiently and resist thermal degradation.
Architectural asphalt shingles with cool roof ratings
remain the most practical choice for most homes, offering 25 to 30 year service
life at moderate cost.
Concrete tile performs well in the local climate and
is common in Spanish and Mediterranean-style homes, though it requires adequate
structural capacity.
Standing seam metal works well for homes with solar
arrays and offers 40 to 50 year longevity.
For the flat and low-slope roofs found on Eichler and
mid-century properties, TPO or PVC single-ply membranes in light colors
meet Title 24 reflectance requirements while handling ponding better than older
tar-and-gravel systems.
Age is the first indicator. Composition shingle roofs
approaching 20 to 25 years and tile underlayment approaching 25 to 30 years
generally warrant replacement evaluation rather than continued patching.
Signs pointing toward repair include isolated leaks,
a few missing or cracked shingles, or damaged flashing at a single penetration.
Signs pointing toward replacement include:
- Granule loss visible in gutters across large areas
- Widespread curling, cupping, or blistering
- Multiple active leaks in separate roof sections
- Sagging rooflines or soft spots underfoot
- Daylight visible through attic sheathing
Maintenance covers debris removal, gutter cleaning,
sealant renewal, and moss treatment — worth scheduling annually, ideally in
early fall before the rainy season begins.
When the repair estimate approaches 30 percent or more of
replacement cost, replacement typically delivers better long-term value.
