How Long Does a Roof Really Last? Here’s What Homeowners Should Know

If you’re like most homeowners, your roof is one of those things you don’t think about… until you have to. But knowing how long your roof is built to last can help you plan ahead, financially and practically, especially here in storm-prone Southeastern Louisiana.

So let’s answer the big question: How long does a roof really last?
Well, it depends on your roofing material, installation quality, and local weather (which, let’s be honest, keeps us on our toes around here).

Here’s what you need to know:

But… Louisiana Weather Changes the Game

Here in Ascension, Livingston, and the surrounding parishes, your roof has to stand up to heavy rain, high humidity, hurricanes, and hail. So even if your shingles are technically rated for 25 years, real-world conditions might shave that down to 18–20. Especially if:

• The roof wasn’t properly ventilated

• Storm damage went unnoticed

• You’ve had multiple insurance patches instead of a full replacement

That’s why it’s smart to inspect your roof regularly (even from the ground!) and schedule a professional inspection after major storms.

Signs It’s Time for a Replacement

Wondering if your roof is nearing the end of its life? Watch for:

• Curled or missing shingles

• Dark streaks or algae growth

• Granules in your gutters

• Daylight peeking into your attic

• Leaks or ceiling stains after storms

Sometimes these issues can be fixed with a repair. But if your roof is already 15–20+ years old, it might be time to start planning for a full replacement.

Quality Installation = Longer Life

Not all roofs are created equal. Even the best materials won’t last long if the install is rushed, sloppy, or missing key steps like:

• Proper underlayment

• Ice & water shield

• Ridge ventilation

• Clean flashing around penetrations
