Keith Roofing Company has been covering Willow Glen roofs for decades — residential and commercial, tile and shingle, repair and replacement. Family-owned since 1952. BBB A+ Accredited. California Licensed #1118418.
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: When you call Keith Roofing for your Willow Glen 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.
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 TPO membrane installations and roof coatings.
Many Willow Glen homes had their original cedar shake replaced with composition shingle in the 1990s — those shingles are now 25–30 years old and due for replacement again, often with deck damage underneath.
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.
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.
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 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.
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.
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.
Roofing materials and installation techniques should reflect local climate realities — not generic specifications. Here's what Willow Glen's specific weather patterns mean for your roof.
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 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.
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.
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.
The neighborhood's commercial spine — small-commercial flat-roof work on shops, restaurants, and mixed-use above.
Classic Craftsman bungalows with character roofs, original skip-sheathing, and chimney flashing sensitivities.
Spanish Revival homes with concrete and clay tile — our specialty for color-matched lift-and-relay projects.
1920s–30s tile-roof homes that demand careful tear-off technique and matched replacement stock.
Mid-century homes between Meridian and the 87, mostly straightforward shingle re-roofs.
Tudor-influenced architecture with steep pitches, complex valleys, and multi-dormer rooflines.
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.
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.
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.
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.
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.
Our decades-long relationships with Westlake Tile, Monier Lifetile, and Eagle Roofing give us access to color profiles that other contractors simply can't source. For a homeowner wanting to match a 1928 tile, that relationship is the difference between an authentic repair and a visible patch job.
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.
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.

A 1926 Spanish Revival home on Bird Avenue came to us with original clay barrel tile that was structurally sound but surrounded by failing underlayment and deteriorating flashing. The homeowner wanted to preserve the original tile — a legacy red-orange barrel profile no longer in production. We completed a full lift-and-relay: removed, catalogued, and stored each tile course, replaced decking where needed, installed modern synthetic underlayment, renewed all flashing with copper details, and reinstalled the original tile. The project preserved the home's historic character while giving the roof another 40+ years of service life.
