Fast, Reliable Roofing Company Across Los Altos
If you own a home in Los Altos, you already know the drill: a low-pitched ranch roof, a canopy of mature oaks and heritage trees overhead, and moss that shows up faster than you’d like. Tilehurst Roofing provides residential roof repair, inspections, and full replacements across Los Altos, with written pricing before any work starts and a live person answering every call, 24/7. Our crews know the city’s 1950s-1970s housing stock, its tricky 2:12-4:12 slopes, and the way the fog shadow keeps north-facing rooflines damp for months. Call (945) 303-9821 for a free estimate, and you’ll get a real number, in writing, before we ever touch your roof.
Key Takeaways
- Most asphalt-shingle repairs in Los Altos run $180-$340, and full replacements on a typical ranch home run $12,000-$22,000 depending on size and material.
- Los Altos’s low-pitch ranch roofs need underlayment and flashing spec’d differently than steeper roofs elsewhere in the Bay Area.
- Heritage-tree protections mean overhanging oaks often can’t be trimmed, so we design around the canopy instead of fighting it.
- Every repair carries a written guarantee, and if it fails within the 365-Day Done Right Promise window, we return at no charge.
Why Tilehurst Roofing Is Los Altos’s Preferred Roofing Company
Los Altos homeowners call us because the Roofing Company team shows up when we say we will, and we put the price in writing before any work begins. Greg Holloway, who leads Tilehurst Roofing, built the Los Altos service area around a simple rule: answer the phone, arrive in the window you gave, and stand behind the work for a full year. That’s the Kingswell Way, and it’s why local customers who’ve been burned by no-shows and mid-job price changes tend to stick with us.
Our Los Altos reputation rests on specifics. Every job begins with a written quote, not a handshake. Every repair gets a written guarantee delivered before the crew leaves, not mailed a week later. If a repair fails inside the guarantee period, we come back at no charge under the 365-Day Done Right Promise. And the technicians on your roof are background-checked and uniformed, so you know exactly who you’re letting onto your property. Calls are answered by a live person, 24 hours a day, 7 days a week, including evenings and weekends. No voicemail queue, no waiting until Monday.
We’re part of the Kingswell family of roofing companies, founded in 2000. The Los Altos location is independently owned and operated under the Kingswell Guarantee, with dispatch and scheduling coordinated from the brand’s San Francisco Bay Area office. Crews serve Los Altos locally, which means quick response times for everything from a small leak off Foothill Expressway to a full re-roof in South Los Altos.
Roof Inspection in Los Altos
Roof Inspection in Los Altos is the single most useful service for owners of 1950s-1970s ranch homes, because these roofs are at or past their second replacement cycle and the warning signs here are easy to miss: moss creeping up shaded north slopes, granule loss at the valleys, and soft decking hidden under a layer of old composition shingles. A full inspection runs $150-$350 depending on roof size and access, and we deliver a written report with photos, measurements, and a line-item repair or replacement recommendation. Most Los Altos inspections take under two hours, and the report is yours to keep whether or not you hire us.
What We Check on Every Los Altos Roof
We inspect the low-slope runs first, because a 2:12 or 3:12 pitch ponds water differently than a 6:12. We check the underlayment condition at the eaves, the drip edge, the valleys where oak leaves and acorns pile up, and the flashing around vents and chimneys. On Los Altos ranches with heritage oaks overhanging the roofline, we also document moss coverage and any granule erosion that could void a manufacturer warranty on the shingles.
When to Schedule an Inspection
Book an inspection after any storm season, before a remodel that opens walls or ceilings, and before you buy a Los Altos home. Many buyers get an inspection during escrow so they know exactly what the roof will cost them in the next five years. If you’ve owned the home for fifteen years or more and have never had the decking opened up, that inspection is overdue.
Commercial Roofing in Los Altos
Commercial Roofing in Los Altos covers the city’s small retail strips along Main Street and State Street, the office buildings near downtown, and the low-slope commercial structures scattered along San Antonio Road. Most commercial roofs here are flat or very low-pitch, which means the same fog-shadow moisture that grows moss on residential ranches also shortens the life of commercial membrane systems. Typical commercial roof repairs in Los Altos run $400-$1,800 depending on the membrane type and the size of the affected area, while full commercial replacements run $8-$16 per square foot for TPO or modified bitumen systems.
Low-Slope Commercial Systems
Los Altos commercial buildings are overwhelmingly low-slope, so we spec and install TPO, PVC, and modified bitumen membranes rated for near-flat applications. The marine layer that sits over the city from late fall through early spring keeps commercial roofs damp, so we pay particular attention to seam integrity and ponding areas where water stands for days. A commercial roof that is not inspected annually in Los Altos will develop seam failures faster than the same roof in Sunnyvale.
Written Allowances on Commercial Jobs
For larger commercial work, we write allowances into the contract up front. When we open a commercial roof and find saturated insulation or rotted decking, the allowance covers it without a change-order surprise. You approve the number in writing before the work proceeds, which keeps the job moving and the budget honest.
Trusted Brands We Service in Los Altos
Tilehurst Roofing installs and services roofing materials from seven leading manufacturers, so you’re never stuck with a single house brand. For Los Altos homes, we frequently recommend GAF architectural shingles on low-pitch residential ranches, Atlas for homes in the fog shadow where algae resistance matters, and CertainTeed for homeowners who want a specific color or profile to match the neighborhood’s ranch aesthetic. We also work with Owens Corning, IKO, Tamko, and Boral. If you have an existing roof by any of these manufacturers, our crews know the installation specs and can match the product or upgrade it cleanly. Parts and materials are sourced quickly for Los Altos customers, so repairs don’t stall waiting on a shipment.
Common Roofing Company Problems We See in Los Altos Homes
- Moss and lichen eating composition shingles on shaded north slopes. Los Altos sits in the fog shadow of the Santa Cruz Mountains, and the persistent marine layer keeps roofs cool and damp. Moss holds moisture against the granule coating and erodes it, which voids manufacturer warranties years earlier than in sunnier microclimates nearby.
- Low-pitch roofs originally shingled like steep-slope jobs. Many 1950s-1970s Los Altos ranches have 2:12-4:12 pitches, yet the original composition shingles were installed with standard underlayment. That combination ponds water and fails at the second replacement cycle, which is exactly when most homeowners call us.
- Heritage oaks overhanging rooflines with no way to legally trim them back. Los Altos’s heritage-tree ordinance protects large valley oaks citywide, and many overhang rooflines directly. The continuous leaf and acorn debris dams at eaves and valleys demand a shorter maintenance interval here than in any neighboring city, and roofers must work around the canopy rather than cutting it back.
- Decking and flashing failures discovered only after the roof is torn off. On a low-pitch 1960s ranch off University Avenue near downtown Los Altos, our crew tore off a failing 3-tab composition layer and found soft sheathing at the valleys plus no ice and water shield under the low-slope runs. We re-decked the soft sections, ran a peel-and-stick ice and water shield across the low-slope field, set new drip edge and flashing, then finished with a GAF architectural shingle rated to the pitch and valley detail. The heritage oak over the north slope stays untouched.
Pricing for Roofing Company in Los Altos, CA
Roof repair in Los Altos typically runs $180-$340 for small asphalt-shingle fixes like a missing tab or a lifted flashing point. Larger repairs involving decking, valleys, or underlayment run $600-$1,800. A full roof replacement on a typical 1,400-2,200 square foot Los Altos ranch runs $12,000-$22,000 for architectural asphalt shingles, $25,000-$45,000 for concrete tile, and $30,000-$55,000 for standing-seam metal. The low-pitch factor matters: if your roof is 3:12 or below, we’ll spec peel-and-stick underlayment on the low-slope runs, which adds $800-$1,500 to the total but is the difference between a roof that lasts and one that fails at year eight.
What changes the price? The number of valleys, the condition of the decking once we open it, whether the heritage oak canopy requires extra underlayment and moss treatment, and whether the home has multiple low-slope sections. We give you a written price before any work starts, and if we find something unexpected when the roof is open, you approve the change in writing before we proceed. Call (945) 303-9821 for a free estimate.

FAQs About Roofing Company in Los Altos
Los Altos sits in the fog shadow of the Santa Cruz Mountains, so the marine layer hangs over the city more persistently than it does over Sunnyvale to the east. Your roof stays cool and damp for longer stretches, especially on the north slope, and the mature oak canopy that shades so many Los Altos ranches keeps that moisture from burning off. Moss follows the moisture, and the moisture follows the fog and the trees. In Sunnyvale, the same roof gets more direct sun and dries out, so moss is slower to establish. Call (945) 303-9821 to schedule an inspection and get a moss treatment plan that fits your roof’s microclimate.
No, and this is the most common mistake we see in Los Altos. The original 3-tab composition shingles on a 1952-1975 ranch were laid over standard underlayment, which works on steeper pitches but fails on a 2:12-4:12 slope when water ponds. For a low-pitch Los Altos roof, we spec an architectural shingle rated to the pitch plus a peel-and-stick ice and water shield across the low-slope runs. That combination prevents the ponding that kills the second replacement early. For an exact recommendation on your pitch, call (945) 303-9821 for a free estimate.
Not without city approval. Los Altos’s heritage-tree ordinance protects large valley oaks and other mature trees citywide, and many overhang rooflines directly. We can’t limb or clear those branches without a permit, and most homeowners find the approval process slow and uncertain. That’s why we design the roof around the canopy instead of fighting it: extra underlayment, valley detailing that handles continuous leaf and acorn debris, and a maintenance interval that acknowledges the tree is staying put. The canopy is a legal constraint, not a landscaping preference, and we build for it.
Outdated wiring, undersized or damaged framing, failed waterproofing, and the code upgrades a permit triggers once walls are open. This is the single biggest reason a remodel or re-roof quote moves, and it’s why we inspect first, before we quote. When we open a Los Altos roof and find soft decking or no ice and water shield on a low-slope run, we price the fix and get your written approval before we proceed. No change orders on a handshake. No surprises once the work is underway. For an inspection that tells you what’s actually under the shingles, call (945) 303-9821.
Line by line, not headline to headline. Look at the underlayment spec on the low-slope runs, the decking replacement allowance, the flashing and drip edge scope, and whether the bid includes a written guarantee delivered before the crew leaves. A lower bid that skips the peel-and-stick underlayment on a 3:12 ranch roof is not a lower bid; it’s a roof that fails at the second cycle. Tilehurst Roofing gives you a written line-item quote up front, so you can compare exactly what you’re paying for. Call (945) 303-9821 and we’ll walk you through it.
