10 Signs your Bay Area Home's Tile Roof needs Remediation

Living and operating in Alameda and Contra Costa counties means enjoying California’s mild climate, but our seasonal changes—including heavy winter rains, occasional high winds, and summer heat—can take a toll on your tile roof. Whether you’re a homeowner, an HOA managing multiple properties, or a business owner, ensuring your roof is in top condition is critical to avoiding costly water damage and maintaining your property's value.

If you spot any of these 10 warning signs, it's time to schedule an inspection with Global Gutter Systems, the #1 trusted gutter and roof specialist in the East Bay.

1. Cracked or Broken Tiles from Storms & Aging

Alameda and Contra Costa counties experience seasonal rainstorms and occasional high winds that can crack or loosen roof tiles. Cracks let moisture seep into the underlayment, leading to leaks and structural issues—especially in older homes and commercial buildings.

2. Missing Tiles After Windy Weather

If your property is near the hills, open spaces, or the coastline, you’re more likely to experience strong gusts of wind, especially in areas like Oakland, Berkeley, and Walnut Creek. Missing tiles leave your roof vulnerable to moisture intrusion, which can escalate into expensive repairs.

3. Water Stains on Ceilings or Walls – A Sign of Seasonal Leaks

With heavy winter rains, roof leaks become more apparent. If you notice stains on your ceilings or walls, it likely means water is penetrating through the roofing layers. Left unchecked, this can lead to mold and costly interior repairs—something no homeowner, HOA, or business wants to deal with.

4. Moss or Algae Growth – A Common Issue in Shaded Areas

Many neighborhoods in Oakland, Moraga, Orinda, and other tree-lined areas experience moss and algae buildup on tile roofs. This excess moisture leads to deterioration and creates an environment for mold growth, which can spread to your attic and insulation.

5. Sagging Roof Sections – A Warning Sign for Older Properties

A sagging roof could mean underlying structural issues caused by moisture retention or poor drainage. This is especially concerning for HOAs managing older townhomes or businesses in historic buildings, where structural integrity is crucial.

6. Deteriorating Roof Underlayment – A Silent Threat to Your Property

Tile roofs are durable, but the underlayment beneath them breaks down over time, leading to hidden leaks. Homes in Danville, Pleasanton, and Lafayette with original roofs over 20 years old should have their underlayment inspected before issues arise.

7. Granule Loss on Tiles – A Sign of Aging in Sun-Exposed Areas

With California’s intense summer heat, roof tiles lose their protective outer layer over time. If your south-facing roof sections are fading or shedding granules into your gutters, it may be time for remediation to maintain energy efficiency.

8. Poor Drainage & Clogged Gutters – A Major Risk for Property Damage

Homes, HOAs, and businesses with tile roofs and inadequate gutter systems often experience water pooling and debris buildup. This is particularly common in neighborhoods with large trees like Alameda, El Cerrito, and Castro Valley. Clogged gutters force water under roof tiles, leading to leaks and foundation damage.

9. Interior Mold or Musty Smells – A Sign of Hidden Roof Leaks

If you manage multi-unit buildings or commercial properties, musty odors are a red flag that moisture is accumulating in attics or walls due to a leaky roof. Proactive maintenance prevents costly mold remediation and health risks for residents, tenants, and employees.

10. Higher Energy Bills – An Overlooked Sign of Roof Issues

Many property owners in Alameda and Contra Costa counties don’t realize that a failing roof can increase energy costs. Damaged tiles and worn underlayment reduce insulation, forcing HVAC systems to work harder—especially during hot summers in Concord, Livermore, and Brentwood.
