Roof Replacement
When repairs aren't enough, a full replacement protects your home for decades.
A full roof replacement removes your existing roofing system down to the deck and installs new underlayment, flashing, and roofing material. It's the right choice when your roof is too old or too damaged to repair cost-effectively — and it adds immediate value to your home.

Frequently Asked Questions
How long does a roof replacement take?
Most residential roof replacements in San Diego take 2–5 days depending on roof size, complexity, and material choice. Tile roofs take longer than asphalt shingle. Weather delays are rare in San Diego but can add a day.
Do I need a permit for a roof replacement?
Yes. The City of San Diego requires a permit for full roof replacements. Your contractor should pull the permit on your behalf and schedule the required inspections. Be cautious of any contractor who suggests skipping the permit.
Can I stay in my home during the replacement?
Yes, in most cases you can remain in your home. There will be noise and some mess from debris, but the work is exterior and shouldn't require you to vacate. Your contractor will protect interior access points.
How do I decide between repair and replacement?
A good rule of thumb: if the repair cost exceeds 30–40% of a full replacement cost, replacement is usually the better investment. Age matters too — repairing a 25-year-old roof may not be worth it. A licensed inspector can give you an honest recommendation.
