If you’re a homeowner in Louisiana, you know your roof has a tough job. Between the heat, the humidity, and the storms that roll through every year, roofs here take a serious beating.

At Westbank Roofing, one of the first questions we get from homeowners is simple: How much is a new roof going to cost me?

The honest answer? It depends. Roof replacement costs can vary quite a bit depending on several key factors. Here’s what really goes into the price of a roof replacement in Louisiana—without the sugarcoating.

The Average Cost of a New Roof in Louisiana

Most homeowners in Louisiana pay between $5,000 and $20,000 for a full roof replacement. That’s a wide range—but for good reason.

The final price depends on:

  1. The size of your roof

  2. The materials you choose

  3. How complex your roof’s layout is

If you have a smaller home with standard asphalt shingles, you’re likely looking at the lower end of that range. If you’re considering metal roofing, tile, or if your roof has a lot of angles and valleys, the cost climbs from there.

What Factors Affect Roof Replacement Cost?

There’s no one-size-fits-all answer, but here’s what really impacts your price:

Roof Size

Roofing costs are usually measured per “square” (which equals 100 square feet). The bigger your roof, the more materials and labor required.

Roof Pitch and Complexity

Steeper roofs or those with lots of valleys, dormers, or chimneys require more labor and safety precautions—adding to the overall cost.

Material Choice

The material you choose plays a major role in your roof’s price. Here’s a rough breakdown of typical costs per square foot (including labor):

  1. Asphalt shingles: $4 to $7 per sq. ft.

  2. Metal roofing: $7 to $12 per sq. ft.

  3. Clay or concrete tiles: $10 to $20 per sq. ft.

  4. Slate roofing: $15 to $30 per sq. ft.

  5. Synthetic roofing materials: $8 to $15 per sq. ft.

Removal of Old Roof

Tearing off your old roof adds to the labor cost—but it’s important. While some homeowners ask about installing new shingles over the old ones, we don’t recommend it in Louisiana’s humid climate. A clean, solid surface is key for long-lasting performance.

Underlayment and Waterproofing

Quality underlayment, proper flashing, and drip edges protect your home from leaks and storm damage. These aren’t the areas to cut corners, especially along the Gulf Coast.

Other Costs to Keep in Mind

Permits

Most parishes in Louisiana require permits for roof replacements. Permit fees typically run between $150 and $500, depending on your location.

Warranty and Installation Quality

Cheaper isn’t always better. A roof is only as good as the team installing it. Paying a little more for experienced roofers and a strong warranty often saves you money down the line.

Storm-Resistant Upgrades

If you’re in a hurricane-prone area, consider upgrades like impact-resistant shingles or a FORTIFIED Roof™ system. These add to upfront costs but may qualify you for insurance discounts and provide better long-term protection.

Should You Choose the Cheapest Roof Quote?

We get it—everyone wants to save where they can. But choosing the cheapest bid often means cutting corners on materials or labor.

Before you commit to a contractor, make sure your estimate includes:

  1. Removal of the old roof

  2. High-quality underlayment and waterproofing

  3. Proper flashing and ventilation

  4. Cleanup and haul-away of debris

  5. Warranty on both materials and labor

A bargain price might feel good up front—but it could leave you dealing with leaks and repairs sooner than you’d like.

How Long Will Your New Roof Last?

The life of your roof depends on your material choice and the quality of the installation. Here’s a general guide:

  1. Asphalt shingles: 15 to 25 years

  2. Metal roofing: 40 to 70 years

  3. Tile roofing: 50 years or more

  4. Slate roofing: 75 to 100 years

Regular roof maintenance and inspections help extend the life of any roofing system.
