Willow Glen's Trusted
Local Roofer
Willow Glen is one of San Jose's most architecturally distinctive neighborhoods — and one of Keith Roofing's longest-standing service areas. We've been working on Willow Glen roofs since the 1950s, when many of the Craftsman bungalows along Lincoln Avenue, Willow Street, and Minnesota Avenue were already 20+ years old. Today you'll find Keith-installed roofs on hundreds of homes between the 87 freeway and Meridian, from the Spanish Revival cottages off Bird Avenue to the Tudor-influenced homes along Willow Road.
What makes Willow Glen unique is the density of historic architecture. The neighborhood grew rapidly between 1910 and 1940, which means most homes here are 85–115 years old. Original roof systems have typically been replaced two or three times by now, and every one of those replacements had to respect the character of the original home. That's where most general-purpose roofing contractors struggle and where decades of Willow Glen experience matters.
What this means for you: On a house this old the roof covering is rarely the only question. We look at what is under it, how the chimney was flashed the last two times, and whether the new roof will suit a 1920s front elevation. Your quote already allows for those things, so you are not handed a low number that grows once the old roof comes off.
What We See on
Willow Glen Roofs
Most Willow Glen homes are on their third or fourth roof, so part of every estimate is reading what the earlier crews left behind.
The architectural mix dictates the material: Craftsman bungalows almost always mean wood-shake-converted-to-composition-shingle or original composition shingle replacement. Spanish Revivals around Bird Avenue and the Willow Street corridor call for concrete or clay tile — often requiring color-matched legacy tile sourced through our long-standing Monier Lifetile, Westlake Tile (Eaglelite), and Eagle Roofing relationships. The small-commercial buildings along Lincoln Avenue's shopping district are typically low-slope flat-roof systems where we do single-ply membrane installations and roof coatings.
Aging Wood Shake Conversions
A lot of Willow Glen houses traded their first cedar shake for composition shingle back in the 1990s. That second roof is reaching the end of its life now, and when it comes off we often find soft or damaged decking.
Chimney Flashing Failures
Historic Willow Glen homes typically have brick chimneys that need careful flashing renewal every re-roof cycle. Cheap counter-flashing is the #1 cause of leaks we see here.
Spanish Tile Underlayment
Concrete and clay tile roofs common on Bird Ave and Minnesota Ave homes have outlived their underlayment — lift-and-relay is often the right call rather than full tear-off.
Hidden Skip-Sheathing
Many original Willow Glen roof decks are skip-sheathed (spaced 1x boards) from the shake era. Modern composition shingles require solid decking — we catch this at tear-off and overlay properly.
Willow Glen's Specialty: Historic Tile & Character Restoration
Why This Material Works Here
Willow Glen is one of the densest concentrations of Spanish Revival architecture in the South Bay. The 1920s and early 1930s saw a building boom along Bird Avenue, Minnesota Avenue, and the Willow Street corridor that put down hundreds of tile-roofed homes in styles ranging from simple Mission Revival bungalows to elaborate two-story Spanish Colonial estates. Many of these homes are now approaching their centennial, and the roofs that came with them — mostly original concrete tile with a smaller number of clay-tile installations — are the characteristic detail that makes these homes what they are.
Technical Installation Approach
Tile roofs in Willow Glen typically fail at the underlayment, not the tile itself. The original 30-pound felt underlayment installed in the 1920s–30s has long been replaced — usually in the 1970s or 80s — with 90-pound felt or early-generation synthetic. That second-generation underlayment is now 40–50 years old and failing. Meanwhile the concrete or clay tile itself is often in excellent condition with decades of service life remaining.
This is where lift-and-relay becomes the right answer. We carefully number and remove each tile course, inspect and replace the underlayment with modern synthetic products (Owens Corning Deck Defense, CertainTeed DiamondDeck), renew all flashings (chimney, skylight, sidewall, valley), replace the tile battens if present, and reinstall the original tile. Lift-and-relay extends the service life of a Willow Glen tile roof another 30–40 years at 40–60% of full-replacement cost.
Expected Longevity & Value
When new clay or concrete tile is specified, we work with Westlake Tile (formerly Eaglelite), Monier Lifetile, and Eagle Roofing — three manufacturers with deep Bay Area distribution and access to legacy color profiles not stocked by general wholesalers. Modern concrete tile carries 50-year manufacturer warranties; clay tile often carries lifetime warranties. With proper installation and maintenance, a Willow Glen tile roof installed today will likely outlast the current homeowner.
Willow Glen's Climate
and Your Roof
Willow Glen's weather is gentle next to the foothills, but long hot summers and a handful of heavy storms still decide how its older roofs wear. Here is what we plan for.
Summer Heat & UV
Willow Glen summers push 90°F+ with significant UV exposure. Roof surface temperatures on south-facing slopes regularly exceed 150°F during July and August afternoons. Composition shingle with algae resistance and proper attic ventilation is essential to hit the full 30-year warranty life.
Winter Rainfall
Winter rainfall averages 15–18 inches, heavily concentrated between December and March. Atmospheric-river events can drop 3–5 inches in 48 hours. Roofs need properly-sealed flashings at every penetration (chimneys, skylights, vent pipes, sidewalls) and peel-and-stick ice/water shield in valleys to survive these events.
Fog & Fire Exposure
Willow Glen's slight elevation above the Santa Clara Valley floor means less fog exposure than lower-lying neighborhoods but still enough humidity cycling to encourage moss and algae growth on north-facing slopes. Algae-resistant shingles (CertainTeed StreakFighter, GAF StainGuard Plus) are worth the modest upgrade for most homes here.
Practical Implications
The practical implications for Willow Glen roofing: material selection should prioritize UV resistance and ventilation capacity, flashing quality is non-negotiable given winter storm intensity, and algae-resistant materials pay back over the life of the roof in reduced maintenance calls and visual deterioration.

How We Handle Roofing
in Willow Glen
Historic Home Assessment
We start with a thorough roof assessment that accounts for the specific age and architectural period of your Willow Glen home. That means evaluating the existing decking (is it skip-sheathing?), the fascia and trim condition, chimney and flashing integrity, and the original roof system's compatibility with modern replacement options.
Material Matching & Samples
For tile homes, we bring physical samples of candidate tile profiles and colors — because online color matching is never accurate enough for a historic home. For shingle-on-Craftsman homes, we bring architectural shingle samples that complement the original paint palette and trim colors.
Permit & Preservation Review
We handle the City of San Jose permit application and, if your home is in one of Willow Glen's historic conservation overlays, the associated preservation documentation. This adds 2–4 weeks to the timeline but ensures full compliance.
Install With Care for the Home
Our crews work Willow Glen homes with specific attention to the mature trees, narrow driveways, and neighboring homes common to the area. We use landscape protection, magnetic nail sweep cleanup, and disposal coordination that doesn't block streets or disturb neighbors.
Why Willow Glen Homeowners
Choose Us
75 Years of Willow Glen Experience
We've been on Willow Glen roofs since the neighborhood's bungalows were still new construction. That continuity matters — we've seen how specific architectural styles age, which materials hold up, and which contractors' work from past decades reveals its shortcuts.
Legacy Tile Color Access
Years of buying from Westlake Tile, Monier Lifetile and Eagle Roofing mean we can often track down older colors and profiles a general wholesaler no longer stocks. If you are trying to match a 1928 tile, that is what separates a repair nobody notices from an obvious patch.
Craftsman Flashing Expertise
The typical Willow Glen Craftsman has a brick chimney, front and side gables, a front porch roof, and multiple flashing transitions. Each is a potential leak point. We've installed or replaced thousands of these flashings over the decades and know exactly where shortcuts lead to callback leaks.
Fair Quoting for Historic Homes
Historic-home re-roofs often have discovery items — deck rot, failed fascia, inadequate ventilation. We quote realistically on the front end and communicate transparently when discoveries happen, rather than surprising you with mid-project change orders.
