7 Signs Your Fresno Roof Needs Repair Before the Rainy Season

If you’re like most Fresno homeowners, you probably don’t think about your roof until something goes wrong — a leak, a water stain, or even a sudden collapse.

But here’s the reality: by the time you see a roofing issue, it’s often been developing for months — or even years.

And with the rainy season approaching in the Central Valley, now is the time to act.

In this post, we’ll break down the 7 key warning signs that your roof needs repair, how Fresno’s unique climate impacts your roof, and how to get a free inspection before small problems become expensive headaches.

🌧️ Why Roof Maintenance Matters in Fresno

Fresno may be known for its sunshine, but winter rains and high summer heat both take a toll on your roof.

Here’s what your roof goes through in a typical year:

• Intense UV exposure that breaks down shingles

• Sudden temperature shifts (hot days, cool nights) causing expansion/contraction

• Heavy winter rains that expose small cracks or loose flashing

• Windy spring conditions that can lift tiles or shingles

If your roof is more than 10 years old, these cycles can start to add up — and if you’re planning to install solar panels, any existing damage could delay or prevent the project.

That’s why catching roofing issues early is essential — especially before winter storms arrive.

🚩 7 Warning Signs You Need Roof Repair

Here are the most common (and most ignored) signals that your roof might need professional attention:

1. Water Stains on Ceilings or Walls

One of the most obvious red flags. If you see brown spots, streaks, or bubbling paint on the ceiling, it often means water is seeping through the roof and into your attic space.

Even if the leak seems minor now, it can spread quickly — damaging insulation, wood, and drywall.

2. Missing, Cracked, or Curling Shingles

Look at your roof from the street or backyard. Can you spot:

• Shingles that look like they’ve peeled back?

• Cracks or “waves” in the surface?

• Patches that look bare or uneven?

These are signs of shingle failure, and they leave your roof vulnerable to water infiltration.

3. Granules in Gutters or Near Downspouts

If your gutters are filled with little black or gray granules, it’s likely your shingles are deteriorating.

These granules are the outer protective layer — and when they start coming off, your shingles are exposed to the elements.

This is especially common on older roofs (10–20 years).

4. Sagging Roofline

Your roof should have a straight, sturdy structure. If any section of your roof looks like it’s sagging or dipping, it could indicate:

• Structural issues

• Water damage in the decking

• Rotted rafters or supports

This is a serious safety concern and should be inspected immediately.

5. Moss or Algae Growth

Green patches may seem harmless — but moss and algae can trap moisture and cause shingles to degrade faster.

In Fresno’s dry summers, this often appears in shaded areas or where water pools after irrigation.

Left unchecked, it can shorten your roof’s lifespan significantly.

6. Daylight in the Attic

If you can see sunlight coming through your attic boards or roof decking, it means water (and pests) can get through too.

Take a flashlight into your attic and check for any signs of:

• Light streaks

• Damp spots

• Rotting wood or mold

These are all indicators of roof failure.

7. Your Roof Is Over 15 Years Old

Even if you don’t see obvious damage, age alone is a factor. Most roofs in Fresno last:

• 15–20 years for asphalt shingles

• 20–30+ years for tile or metal

If your roof is 15+ years old and hasn’t had a recent inspection, there’s a high chance small issues are forming under the surface — especially around vents, chimneys, and flashing.

🧱 Why Roof Repair Matters Before Going Solar

If you’re considering solar panel installation, roof condition is critical.

Here’s why:

• Solar panels last 25+ years — but if your roof fails before that, they’ll need to be removed for a re-roof

• Damaged roofs can’t safely support mounting systems

• Many solar installers will refuse to install on an unfit roof

At One Sun Solutions, we assess your roof’s condition before every solar project. If repairs or upgrades are needed, we handle them in-house to avoid delays or subcontracting.
