Asphalt Shingle Roof Replacement in San Bruno, CA

Architectural asphalt shingles remain the most popular roofing material in San Bruno, CA, and for good reason: they balance cost, durability, and curb appeal better than any alternative. A full asphalt shingle roof replacement removes every layer of old roofing down to the deck, repairs any damaged sheathing, and installs a complete new system — underlayment, flashing, shingles, ridge caps, and ventilation — engineered to last 25 to 30 years.

What This Service Includes

An asphalt shingle replacement is not a layover or a patch job. We strip the roof to the bare wood deck, which lets us find and fix the hidden problems that shorten roof life: rotted sheathing, rusted flashing, failed valleys, and inadequate ventilation. Then we build the new roof as a complete system, with each layer working together.

Signs You Need This Service

• Curling, cupping, or clawing shingles
• Bald spots where protective granules have worn away
• Cracked or missing shingles after wind events
• Dark streaks or moss growth on north-facing slopes
• Daylight visible through roof boards in the attic
• A roof age of 20+ years on 3-tab or 25+ on architectural shingles

How We Do It Right

We install laminated architectural shingles rated for high wind, with synthetic underlayment, ice-and-water shield at eaves and valleys, new drip edge, and corrosion-resistant flashing. In San Bruno, we recommend algae-resistant blends on shaded slopes, and we always bring attic ventilation up to current standards.

Asphalt Shingle Roof Replacement for San Bruno Homes

In San Bruno, architectural shingles with algae-resistant granules are the standard, with careful attention to corrosion-resistant flashing. Architectural shingles with the right underlayment and ventilation handle persistent marine-layer fog, salt air, and gusty Peninsula winds reliably for 25 to 30 years, which is why they remain our most-installed system.

Frequently Asked Questions

How long does an asphalt shingle roof replacement take?

Most single-family homes in San Bruno take one to two days for a full tear-off and replacement. Larger or more complex roofs can take three days. Weather is the main variable — we never tear off more than we can dry in the same day.

Can you install new shingles over my old roof?

In most cases we recommend a full tear-off. A second layer hides deck damage, adds weight, voids most manufacturer warranties, and shortens the new roof's life. Tear-off costs more upfront but delivers a roof that actually lasts.
