Why maintenance matters here
The Central Valley is hard on roofs. Summer heat above 100°F makes shingles expand and contract. That causes granule loss over time.
Winter rains then test every seal and flashing joint. Skip regular maintenance and a 25-year roof can fail in 15.
Spring checklist (March–May)
Winter rains are done. Now check what they left behind:
- Gutters and downspouts. Clear debris. Check that water drains freely.
- Flashing. Look around chimneys, vents, skylights, and wall edges.
- Shingles. Look for missing or loose ones. Wind and rain can loosen them.
- Algae or moss. Rare in the Central Valley, but check shaded areas.
- Tree branches. Keep at least 6 feet of clearance from the roof.
- Attic stains. Water marks mean a winter leak got in.
Summer checklist (June–August)
Heat between 100–110°F is your roof’s worst enemy. Focus on these:
- Attic airflow. Attic temps should stay below 120°F. Poor airflow cooks shingles from below.
- Pipe boots and rubber seals. UV and heat break down rubber in 5–8 years.
- Blistering or curling shingles. These are early heat damage signs.
- Granule loss. Granules in your gutters mean shingles are aging fast.
- Insulation. Good insulation cuts heat transfer and lowers cooling bills.
Fall checklist (September–November)
Get your roof ready before the rains return:
- Clean gutters. Leaf buildup causes water backup and wood rot.
- Seal cracks and gaps. Caulk around all roof penetrations.
- Check drainage. Water should flow away from the foundation.
- Schedule a pro check. Catch small problems before the wet season starts.
Winter checklist (December–February)
During the wet season, stay alert:
- Watch for leaks. Check your attic during heavy rain for active drips.
- Keep gutters clear. Storms move debris fast.
- Look for ponding water. Especially on flat or low-slope areas.
- Photograph damage. Photos make insurance claims much easier.
What you can do vs. what needs a pro
You can do ground checks and gutter cleaning yourself. Leave these to a professional:
- Walking on the roof. Fall risk, and hot shingles crack easily.
- Flashing repairs and resealing.
- Pipe boot swap-outs.
- Attic airflow changes.
- Any work on a roof steeper than 6/12 pitch.

Frequently asked questions
Twice a year is ideal here. Once in spring after winter rains. Once in fall before the wet season starts. Roofs over 15 years old should get an annual pro inspection.
We do not recommend it. You can fall. In summer heat, shingles are soft and crack under foot. Use binoculars from the ground, or hire a pro.
UV damage from extreme heat. It causes shingle granule loss, rubber seal failure, and premature aging. Proper ventilation and reflective materials help combat this.
A pro maintenance visit runs $200–$500. That depends on your roof size and what needs fixing. Compare that to $8,000–$25,000+ for a new roof. Regular maintenance is a good deal.
