Most San Diego homes have asphalt shingle roofs. They are affordable, they look good, and when installed correctly, they hold up well against our climate. But they do not last forever.
If your shingles are 20 years old or showing serious wear, replacement is probably coming. Here is what you need to know.
When Replacement Makes Sense
Some roof problems can be repaired. A few missing shingles after a windstorm, a small leak around a vent pipe, damaged flashing - these are fixable without replacing the whole roof.
But there comes a point when repairs stop making sense. If you are calling a roofer every year or two for new problems, you are probably past that point.
Look at your shingles from the ground with binoculars, or ask a roofer to inspect. Signs that suggest replacement:
- Shingles curling at the edges or cupping in the middle
- Large areas of missing granules (you will see dark patches)
- Multiple shingles cracked or broken
- Daylight visible through the roof boards in your attic
- Water stains on ceilings in multiple rooms
Age matters too. A 25-year shingle does not always last 25 years, especially in San Diego. Our sun is brutal. UV radiation breaks down asphalt faster than in cloudier climates. If your roof is past 20 years and showing wear, do not be surprised.
When you get bids, contractors will talk about shingle grades. The main categories are three-tab shingles (flat, basic) and architectural shingles (dimensional, textured). Architectural shingles cost more but look better and typically carry longer warranties.
Pay attention to what is included in the bid. Does it cover removing the old roof completely, or just layering over? Complete tear-off is almost always better. You want to inspect the sheathing underneath and start fresh with new underlayment.
Does the bid include replacing damaged sheathing? Flashing around vents and chimneys? Ice and water shield in valleys? These details matter.
After installation, your new roof needs minimal maintenance. Keep gutters clear, trim back overhanging branches, and walk the property after major storms to spot any obvious damage. That is about it.
