Roof Replacement in San Leandro, California

The post-war roofs across San Leandro are decades past their service life, and the fog has streaked them with algae over the years. Roof replacement in San Leandro gives the home a new, complete roof system built for the East Bay climate.

Signs Your San Leandro Roof Needs Replacement

• The shingles are curling or cupping — the damp and the age have worn the asphalt
• The algae streaks are widespread — the algae has degraded the shingle surface
• The granules are gone from the shingles — the roof is past the point of the repair
• The roof is over 20 years old — the shingles have reached their service life
• The roof has had repeated repairs — the patches are not holding and the replacement is the better value

Why San Leandro Roofs Need Replacement

The East Bay climate is the main factor in the roof replacement. The fog and the salt air degrade the shingles and the flashing. The post-war homes are decades past their life.

The replacement gives the home a modern roof system. The architectural shingles, the corrosion-resistant flashing, and the ventilation handle the coastal climate better than the old roofs.

How We Replace Roofs in San Leandro

1. Inspect the roof and the deck — check the shingles, the flashing, and the decking
2. Choose the material — the architectural shingles or the metal for the coastal climate
3. Tear off the old roof — remove the shingles and the underlayment, inspect the deck
4. Install the underlayment — the synthetic felt or the ice-and-water shield at the eaves
5. Install the flashing — the corrosion-resistant drip edge, step flashing, and valley flashing
6. Install the shingles or the metal — the material in the manufacturer’s pattern
7. Install the ventilation — the ridge vent and the soffit vents for the balanced airflow

Preventing Roof Problems in San Leandro

• Replace the roof before the algae takes over — the algae degrades the shingle surface
• Choose the algae-resistant shingles — the granules resist the streaking
• Include the ventilation — the airflow dries the roof and slows the algae
• Inspect the decking during the tear-off — the hidden rot is revealed then

Expert tip: in San Leandro, the roof replacement should include the ridge vent and the soffit vents. The airflow dries the roof and slows the algae and the moss. The ventilation is as important as the shingles in the fog.
