What’s different about Louisiana

Louisiana's hurricane risk drives wind-rated construction, and persistent humidity and flood exposure raise exterior maintenance and insurance-related costs.

  • Hurricane codes require wind-rated shingles, extra fasteners, and sealed decking.
  • Algae-resistant shingles are popular where humidity drives streaking.

Expect quotes toward the higher end in Louisiana’s larger metros — New Orleans, Baton Rouge, and Shreveport — where labor and permit costs run above the state average, and lower in rural areas.

How the cost is built

Roof cost scales with roof area (measured in 100 sq ft 'squares'), pitch, and material — asphalt shingles are the budget choice, while metal, tile, and slate run two to four times more. Steep or complex rooflines, multiple layers to tear off, and new decking or flashing all add to the total.

Resale value

A new asphalt-shingle roof recoups roughly 60% of its cost at resale, per the annual Remodeling Cost vs. Value report — and it's often what lets a home sell at all.
