San Diego County may be known for its sunshine, but when the winter rains arrive, they can test even the best-maintained roof. The region gets most of its annual rainfall in just a handful of winter storms, which means roof problems sit hidden for months and only reveal themselves when the first downpour hits. That’s why preparation before the rain starts is essential.
At Bernal Roofing Systems, we’ve been helping homeowners across San Diego County protect their homes from water damage. Here’s your complete guide to rainy season roof preparation, with the professional expertise you can count on.
Why San Diego Roofs Need Special Attention
The San Diego climate does a unique kind of damage to roofs. Long, hot, dry summers bake roofing materials, dry out caulk and roof cement, and make asphalt shingles brittle. Along the coast—from Oceanside to Imperial Beach—salt air corrodes flashing, fasteners, and gutter hardware. By the time rain arrives, your roof has spent most of the year quietly degrading with no symptoms to warn you.
That’s why a pre-season inspection is so important. As roofing expert Martin Carr of Carlsbad explains, “If the rain gutters aren’t cleared out, and then you get rain, the rain will obviously fill the gutter, and overflow, which can cause leaks”.
Your Pre-Rain Roof Checklist
1. Clear Your Gutters and Downspouts
Clogged gutters are one of the leading causes of roof leaks in San Diego. Leaves, jacaranda debris, palm fronds, and the grit that washes off aging shingles can block water flow and cause overflow.
What to do:
- Remove all debris from gutters and downspouts
- Run a hose through gutters to check for proper flow
- Ensure downspouts direct water at least 4-6 feet from your foundation
- Check for sagging sections that hold standing water
2. Inspect Flashing and Roof Penetrations
Most roof leaks don’t happen through the shingles themselves—they happen where water can get underneath. Flashing around chimneys, vents, skylights, and where the roof meets a wall are the most common failure points.
What to look for:
- Loose or rusted metal flashing
- Cracked or dried-out caulk and sealant
- Exposed nails that could allow water entry
- Gaps around skylights and vent pipes
3. Check Your Shingles and Tiles
For asphalt shingle roofs (which make up about 75% of San Diego roofs), look for curling, cupping, granule loss, and bald spots. If you’re finding granules in your gutters, that’s a sign your roof is aging.
For tile roofs, look for broken, cracked, or slipped tiles. Remember that the tiles themselves are largely a UV shield—the underlayment underneath is the actual waterproof layer, and it has a much shorter lifespan than the tile.
Red flags:
- Missing or damaged shingles or tiles
- Granules accumulating in gutters or on the ground
- Curling or lifting shingles
- Cracked or broken tiles exposing underlayment
4. Don’t Forget the Attic
Your attic can reveal problems before they become visible in your living space. After a rain, check for water stains, damp spots, or any signs of moisture. “If you have a leak, get somebody to inspect it and make sure they look in the attic as well,” advises Carr.

When to Call a Professional
While you can handle basic gutter cleaning and visual inspections yourself, some jobs require professional expertise:
- Your roof is over 10 years old
- You spot damaged or missing shingles from the ground
- You notice water stains or moisture in your attic
- You’re unsure about what you’re seeing
- You need to access a steep or multi-story roof
Safety reminder: Never walk on a wet, tile, or steep roof yourself. A lot can be assessed from a ladder at the eaves or with binoculars from the ground.
