Call (877) 367-1429

We’ve worked in Hillsborough since the 1980s, long enough to know that a roof here is not just a roof. The town’s 1920s-1950s estate homes on the hills above Burlingame and San Mateo were built with clay barrel tile, slate, and wood shake systems that demand specialized knowledge most Bay Area contractors simply do not carry. Our crews have replaced roofs on homes along Skyline Boulevard, in the St. Matthews neighborhood, and throughout the 94010 zip code - always with the understanding that Hillsborough’s Town Architectural and Design Review (ADR) process mandates approval for any exterior material or color change before a permit is ever issued. That regulatory layer does not exist in neighboring Burlingame or San Mateo. We know how to navigate it because we’ve done it dozens of times.

Our Roof Replacement & Installation Services in Hillsborough

Tile Roofing and Period-Matching Restoration

Tile roofing is the signature of Hillsborough’s historic housing stock. The Spanish Colonial Revival and Mediterranean estates built between 1920 and 1955 were roofed with clay barrel tiles that are now 70-100 years old. Many are failing from coastal salt corrosion, freeze-thaw cracking, and decades of moss and lichen infiltration. We source salvaged and custom-blended tile from specialty suppliers to match original profiles, glazes, and weathered colors - because Hillsborough’s ADR board has historically rejected permits when replacement tile looks too new or too different. A standard “reroof” here is a materials-research and approval project as much as a construction job. We handle both.

Full Roof Replacement

When a Hillsborough roof has reached the end of its service life, we strip to the deck, assess structural integrity, and rebuild with systems engineered for this specific environment. That means corrosion-resistant fasteners and flashings rated for salt-laden marine air, proper underlayment selection for shaded, damp conditions, and ventilation calculations that account for dense tree canopy coverage. We recently completed a full roof replacement on a 1929 Spanish Colonial Revival estate in the St. Matthews neighborhood, where the original clay barrel tiles were failing due to coastal salt corrosion. We sourced period-matching salvaged tiles and used galvanized hardware throughout to meet both the ADR’s aesthetic standards and the demands of the salt-air environment. The job took eleven days from permit approval to final inspection.

Asphalt Shingles

While less common on Hillsborough’s historic estates, asphalt shingles do appear on certain additions, guest houses, and newer construction. We install GAF and CertainTeed systems with algae-resistant granules formulated for shaded, damp climates - a necessity here where the dense oak and redwood canopy keeps roof surfaces cool and moist year-round. We never substitute materials without documentation; the brand on the estimate is the brand on the roof.

Metal Roofing

Standing-seam and metal tile systems are increasingly specified for Hillsborough homes where homeowners want the profile of traditional tile with reduced weight and maintenance. We install coated steel and aluminum products from Atlas and Tamko with marine-grade finishes that resist the salt corrosion that destroys standard galvanized fasteners within 5-7 years. Every metal roof we install in Hillsborough includes proper isolation from dissimilar metals to prevent galvanic corrosion at flashings and penetrations.

Trusted Brands We Service in Hillsborough

We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Hillsborough’s tile restoration work, we maintain relationships with specialty salvage yards and custom tile producers who can match historic profiles that are no longer in standard production. This is not a matter of walking into a supply house and picking from a rack. The right tile for a 1934 Mediterranean on El Camino Real might need to be fired to order or reclaimed from a demolished estate in Pasadena. We have spent decades building those supplier relationships so Hillsborough homeowners do not face ADR rejection mid-permit because their contractor stocked only new-production standard tile.

Common Roof Replacement & Installation Problems We See in Hillsborough Homes

• Salt-laden fog corrosion. Marine air from the Pacific carries chloride salts that attack galvanized steel fasteners, flashings, and hardware on garage doors and roof systems alike. In Hillsborough’s exposed hillside locations, we see fastener heads deteriorated to structural failure within 5-7 years - corrosion rates far exceeding inland Bay Area neighborhoods. We specify stainless steel and marine-grade coated hardware for all replacement work.
• Moss and algae acceleration under dense canopy. Hillsborough’s mature oak, redwood, and eucalyptus canopy creates perpetual shade and moisture retention on roof surfaces. Clay tiles that would dry within hours in a sun-exposed San Bruno neighborhood stay damp for days here. That moisture feeds moss and lichen growth that infiltrates tile pores, leading to freeze-thaw cracking and spalling. Our inspections include assessment of tree clearance and drainage patterns, not just surface condition.
• Complex geometry concentrating water risk. The estate homes of Hillsborough were designed with multiple valleys, dormers, turrets, and intersecting roof planes that create dozens of linear feet of flashing - each a potential failure point. Wet winters averaging 20-24 inches of rain concentrate infiltration at these intersections. Valley flashings corrode first; we replace them with wider, heavier-gauge material and improved waterproofing membranes.
• Original clay tile reaching end of service life. Many Hillsborough clay tile roofs are 80-100 years old. The tiles themselves may be sound, but the mortar ridge caps, hip closures, and underlayment have long since degraded. A proper restoration addresses the full system, not just the visible surface. We remove, clean, and reinstall salvageable tile while replacing all substrate components.
