Metal Roof Over Shingles (Retrofit) in Lafayette

Lafayette sits on the flat Vermilion River prairie, on heavy clay and bayou lowland about 30 miles from the Gulf, under live oaks, pecans and crape myrtles that drop debris on every roof in town. From the 1950s-70s brick ranches off the Oil Center and Broadmoor to the 1980s-2000s subdivisions along Ambassador Caffery and River Ranch, most of these homes still carry one or two layers of aging asphalt shingles. A metal roof over shingles (retrofit) in Lafayette lets you skip the tear-off, cut the waste, and put a wind-rated metal roof on the same deck. We check the deck first and tell you straight when a full tear-off is the better call. If you want the full picture on panel options, start with our metal roof installation page.

Why Lafayette Homeowners Retrofit Over Shingles

Acadiana roofs take hurricane and tropical-storm wind, steamy humidity, salt-tinged air, intense UV and torrential afternoon downpours. Asphalt shingles in this climate curl, lose granules and trap heat, and after repeated storm seasons many Lafayette roofs are one layer away from a leak. A retrofit puts a metal skin over that shingle bed, which adds a second drainage plane and reflects summer heat instead of soaking it in.

• You avoid tearing off a ton or more of shingles, so the dumpster and disposal bill drops.
• The existing shingles stay in place as an underlayment layer, which saves a full day on many ranch homes.
• Metal sheds oak and pecan debris better than worn asphalt, which matters under the big trees in the Saint Streets.
• You can often keep living in the house, since there is no open deck exposed to afternoon storms.

That said, a retrofit is only as good as the deck underneath, and we verify that before we quote a panel.

Key info: A 1960s brick ranch off Broadmoor with one layer of shingles is a textbook retrofit. A 1920s Creole cottage in the Saint Streets with three layers and soft decking usually needs a tear-off first.

Local code limits how many existing shingle layers you can recover over, and the City of Lafayette and parish building departments set their own thresholds and inspections. Check the Lafayette Consolidated Government permit office before you schedule anything.

How We Retrofit a Metal Roof Over Shingles in Lafayette

We do not sell a retrofit sight unseen. The deck decides the method, and the method decides the price. Here is the sequence we run on every Lafayette-area home, from a River Ranch two-story to a low ranch in Scott.

1. We walk the attic and the roof to check decking, rafters and any soft spots from old leaks.
2. We measure the existing shingle layers and confirm the local code limit for recover.
3. We repair or replace bad decking and refasten loose sheathing before anything goes on top.
4. We install a slip sheet or underlayment over the shingles to separate the old surface from the new metal.
5. We set new eave trim, rake trim and penetration flashing, since old shingle flashing will not seal to metal.
6. We install the panels with the correct fastener pattern for our wind zone and torque every screw to spec.
7. We clean the gutters, magnet-sweep the yard and walk the job with you before we leave.

Each step is documented with photos, which also helps if you file an insurance claim after a storm.

Local example: On a 1970s split-level near Girard Park, we found two shingle layers and one rotten valley. We replaced the valley decking, installed a slip sheet, and set a standing seam panel over the top. The homeowner kept the original shingles in place and saved the tear-off cost.

If your existing roof is already metal and leaking at the fasteners, that is a different job. See our screw replacement and re-fastening service instead.

Retrofit Approaches We Use Across Lafayette

Not every panel belongs on every roof. The right approach depends on the pitch, the number of shingle layers and how visible the roof is from the street. Here is how we match method to house.

Metal Roof Over Shingles (Retrofit) Cost in Lafayette: What to Expect

Retrofit pricing starts around $7 per square foot for a basic exposed-fastener panel over sound decking. Standing seam, stone-coated steel and complex roofs with multiple valleys or dormers run higher. The number moves mostly on deck condition, panel type, roof pitch and how much trim and flashing the house needs.

• Deck repairs add cost, and soft sheathing is common on 1950s-70s ranches around the Oil Center.
• Panel choice matters most, since standing seam costs more than a screw-down ribbed panel.
• Roof complexity drives labor, especially steep hips and gables on Victorian and Queen Anne homes.
• Access and height add time, such as two-story homes and tight lots in Freetown.
• Flashing and penetration work is not optional, and old chimneys and skylights often need new metal.

Get two or three written estimates on the same scope so you compare apples to apples, not a low bid that skips the deck work.

Metal Roof Over Shingles (Retrofit) Near Me: How to Vet a Lafayette Contractor

Anybody with a truck can promise a cheap retrofit. The contractor you want can show a Louisiana license, carry liability and workers comp, and explain the local recover limit without guessing. Ask for the certificate, call two recent references, and confirm who pulls the permit.

• Confirm the license and insurance in writing before work starts.
• Get at least three estimates and compare scope line by line, not just the total.
• Ask for addresses of recent retrofits in Lafayette, Scott or Broussard you can drive past.
• Check HOA and historic-district rules on panel profile and color before you order material.
• Make sure the contract states who handles permits and inspections.

If a bid is far below the others, ask what it leaves out, because deck repairs and flashing are where cheap jobs cut corners.
