Roof maintenance checklist
for Central Valley.

Why maintenance matters in the Central Valley

The Central Valley is hard on roofs. Summer temperatures above 100°F cause shingles to expand, contract, and lose protective granules. Winter rains test every seal and flashing joint. Without regular maintenance, a 25-year roof becomes a 15-year roof.

Spring checklist (March - May)

After winter rains, inspect for damage:

• Check gutters and downspouts — clear debris, check for proper drainage
• Inspect flashing — around chimneys, vents, skylights, and wall junctions
• Look for missing or damaged shingles — wind and rain can loosen them
• Check for algae or moss growth — less common here, but possible in shaded areas
• Trim overhanging branches — keep 6+ feet of clearance from the roof
• Inspect attic for water stains — signs of winter leaks

Summer checklist (June - August)

Central Valley summer heat (100-110°F) is the #1 enemy of your roof:

• Check attic ventilation — attics should not exceed 120°F; poor ventilation cooks shingles from below
• Inspect pipe boots and rubber seals — UV and heat degrade rubber in 5-8 years
• Look for blistering or curling shingles — signs of heat damage
• Check granule loss — excessive granules in gutters mean shingles are aging
• Ensure proper insulation — reduces heat transfer and cooling costs

Fall checklist (September - November)

Prepare for winter rains:

• Clean gutters thoroughly — leaf buildup causes water backup and fascia damage
• Seal any cracks or gaps — caulk around penetrations
• Check drainage — water should flow away from the foundation
• Schedule a professional inspection — catch problems before the wet season

Winter checklist (December - February)

• Monitor during storms — check attic for active leaks during heavy rain
• Keep gutters clear — heavy rains move debris quickly
• Check for ponding water — especially on flat or low-slope sections
• Document damage — photos help with insurance claims if needed

Professional maintenance vs. DIY

Homeowners can handle ground-level visual inspections and gutter cleaning. Leave these to professionals:

• Walking on the roof (safety risk + can damage shingles)
• Flashing repairs and resealing
• Pipe boot replacement
• Attic ventilation modifications
• Any repair on a roof steeper than 6/12 pitch
