If you own a home in San Diego, you know your roof quietly protects everything you value. But roofs don’t last forever, and replacing yours at the right time can prevent costly damage to your home’s structure and interior.
Whether you have shingles, tile, metal, or flat roofing, understanding when to replace your roof is essential for maintaining your property’s value and avoiding unexpected emergencies.
At Dana Logsdon Roofing & Solar, we’ve been helping San Diego homeowners for over 30 years. Here’s what you need to know about roof lifespans, warning signs, and the best time to schedule a replacement.
Average Roof Lifespans in San Diego
How often you should replace your roof depends heavily on the material and how well it’s maintained.
Below are averages you can expect in Southern California’s coastal and inland climates:
| Roofing Material | Average Lifespan |
|---|---|
| Asphalt Shingles | 20–30 years |
| Clay or Concrete Tile | 40–60 years |
| Metal Roofing | 50–70 years |
| TPO Roofing | 15–25 years |
| PVC Roofing | 20–30 years |
| Torch Down Roofing | 12–15 years |
What Makes San Diego Roofs Age Faster?
While San Diego’s weather is more temperate than other parts of the country, several local factors shorten roof life:
-
Intense UV exposure that breaks down shingle oils and dries out membranes.
-
Salt air near the coast that corrodes metal fasteners and flashing.
-
Occasional heavy rain that tests underlayment and drainage systems.
-
Wildfire exposure in some inland areas that requires Class A fire-rated materials.
Even well-installed roofs eventually wear down. Routine inspections help spot issues early so you can plan ahead.
Signs It’s Time to Replace Your Roof
If your roof is near or past the expected lifespan, watch for these warning signs:
1. Missing or Damaged Shingles or Tiles
-
Bald spots where granules are gone.
-
Curled, cracked, or loose shingles.
-
Broken or slipped clay tiles exposing underlayment.
2. Persistent Leaks and Water Stains
-
Recurring leaks even after repairs.
-
Water stains on ceilings and walls.
-
Musty smells in the attic or crawlspace.
3. Sagging Rooflines
-
A drooping ridge or uneven slopes.
-
Soft spots when walking on the roof deck.
4. Excessive Granule Loss
-
Granules accumulating in gutters and downspouts.
-
Shingles look shiny or bare.
5. Failing Underlayment
-
Roofs older than 15–20 years often have underlayment that has deteriorated.
-
Even if your tile looks fine, old underlayment can lead to leaks.
6. Increased Energy Bills
-
Poor attic ventilation and degraded materials can trap heat, raising cooling costs.
If you see any of these issues, it’s time to schedule an inspection to understand your options.
Should You Repair or Replace?
When damage is isolated and your roof is still within its lifespan, repairs may be enough. But if multiple areas show wear, it’s usually more cost-effective to replace everything at once.
Here’s a simple guide:
| Condition | Recommendation |
|---|---|
| Isolated damage, newer roof | Repair |
| Recurring leaks, multiple repairs | Replace |
| Widespread material failure | Replace |
| Roof over expected lifespan | Replace |
