EPDM Rubber Roofing in Shreveport, LA

EPDM (ethylene propylene diene monomer) is a synthetic rubber sheet that has been covering flat roofs for decades. Plenty of churches, schools, office buildings and older retail centers around Shreveport and Bossier City still have one. Call (318) 287-8236 and we will connect you with an independent licensed commercial roofing contractor who works on EPDM. Shreveport Commercial Roofing Pros is a referral service; the contractor inspects, quotes and does the work.

Who usually calls about EPDM

• Owners of an aging rubber roof who are seeing leaks at the seams or around penetrations and want to know if repair still makes sense.
• Facility managers comparing EPDM with TPO for a replacement and wanting an honest side-by-side.
• Buildings with irregular shapes where large rubber sheets can cover big areas with fewer seams.
• Budget-driven projects, since EPDM is often among the lower-cost membrane options in national cost guides.

How EPDM differs from TPO

Both are single-ply membranes, but they behave differently. EPDM is a thermoset rubber, so its seams cannot be heat-welded. Instead, laps are joined with seam tape or adhesive. When those taped or glued seams are installed well, they perform; when the surface was not cleaned and primed properly, they are the first place an EPDM roof opens up. EPDM is very flexible and tolerates building movement well. Most EPDM is black, which absorbs heat; white EPDM exists and costs more. TPO is white by default and its welded seams are generally considered stronger, which is why many replacements around the area have shifted toward TPO. Neither choice is right for every building.

Installation methods

1. Fully adhered. The sheet is glued to the insulation or cover board. This is the most common approach on buildings that need a smooth, wind-resistant surface.
2. Mechanically attached. Fasteners and plates or batten strips hold the sheet, with the seams covering the fasteners.
3. Ballasted. Loose-laid sheet held down with river rock or pavers. Older buildings sometimes have this; it requires a structure that can carry the weight and is less common in areas exposed to strong storm winds.

Typical thicknesses are 45, 60 and 90 mil. Under the membrane sits insulation, often tapered to move water toward drains, and ideally a cover board.

Signs an EPDM roof is near the end

• Seams peeling back at the edges of the tape or lap
• Membrane shrinking and pulling away from walls and curbs, sometimes stretching tight across inside corners
• Surface crazing or a chalky feel after years of sun
• Repeated patches that keep failing in the same areas
• Soft or spongy spots underfoot, which point to wet insulation
• Ballast stones scattered off the roof after a windstorm

Repair, coat or replace?

A rubber roof with a few bad seams and dry insulation can often be repaired with new seam tape, cover strips and re-flashed penetrations. An older EPDM roof that is mostly intact may also be a candidate for a coating system designed for rubber; ask the contractor whether the coating manufacturer approves application over EPDM and what primer it requires. When a moisture survey shows a large share of the insulation is wet, coatings and repairs usually just delay the bill, and replacement becomes the realistic option.

Typical EPDM cost ranges

These are typical ranges from national cost guides, shown only to help you budget. They are not quotes for your building.

Costs move with roof size, tear-off layers, deck condition, access for equipment and how many penetrations need flashing. Our cost guide walks through those factors.

Timeline

Repairs are often a single visit. A full EPDM replacement on a modest building may be finished in a few working days, while larger roofs take longer. Adhesives and seam primers have temperature and moisture limits printed on the product labels, so humid mornings, dew and rain can push start times later in the day. Ask the contractor to explain how weather will affect their schedule.

EPDM around Shreveport-Bossier: local specifics

Which buildings have it. Black rubber roofs are most common on buildings from the decades before TPO took over: church education wings and fellowship halls, older school additions, small office buildings and neighborhood retail. Many of these sit in or near Shreveport's older neighborhoods such as Highland, South Highlands and Fairfield, which are local historic districts. The Shreveport-Caddo MPC's Historic Preservation Commission reviews certificates of appropriateness in those districts, and its case list includes a roof replacement with material changes in the Fairfield district. If your building is in a historic district and the roof is visible from the street, ask whether a certificate is needed before switching materials.

Cold matters too. During the February 2021 arctic outbreak, the National Weather Service recorded 1°F at Shreveport Regional Airport on February 16, and much of the area stayed below freezing from about February 13 to 18. EPDM stays flexible in cold, but seam adhesives, frozen drains and ice sitting on a roof for days all test an older rubber roof. A roof walk after any hard freeze is worth scheduling.

Ballast and wind. On June 1 and 2, 2004, the Weather Service found straight-line winds of 85 mph or higher in spots across the region, with thousands of trees down across Shreveport-Bossier. Older ballasted rubber roofs depend on stone staying in place; scattered ballast after a storm means the sheet below needs a look.

Humid mornings. With pre-dawn humidity at 90 percent or higher on most nights, seam primer and tape work often waits for the roof to dry. Ask how the crew checks surfaces before taping.

Questions worth asking

• Are you proposing EPDM because it suits this building, or because it is the cheapest option you install?
• What thickness, and is the sheet reinforced?
• Fully adhered, fastened or ballasted, and why?
• How will seams be cleaned, primed and taped, and will you send photos?
• What happens to existing ballast if the roof has it?
• What does the warranty cover, for how long, and who issues it?

Checking a contractor before you sign in Louisiana

• State license on larger jobs. The Louisiana State Licensing Board for Contractors (LSLBC) requires a commercial license for commercial projects valued at $50,000 or more, counting labor and materials. Roofing falls under the board's "Roofing and Sheet Metal, Siding" subclassification of Building Construction, and a contractor may also hold the broader Building Construction classification. Ask for the license number and look it up on the LSLBC website. A contractor's name on a truck is not proof of a license.
• Small apartment buildings. For buildings used mainly as residences with up to four units, the LSLBC says roofing work of $7,500 or more requires the Residential Roofing or Residential Construction classification as of August 1, 2026. Owners of duplexes and fourplexes should ask which license covers their job.
• Permits. The LSLBC says Act 239 of 2025 requires permitting and inspection of roof construction and reroofing on residential and commercial structures for projects beginning on or after August 1, 2025. Inside Shreveport the permit comes from the city's Division of Permits and Inspections at Government Plaza; in Bossier City it comes from the Permits & Inspections Division on Benton Road. Ask the contractor to pull the permit in the contractor's name and schedule the inspections. Our guide to commercial roof permits and codes in Shreveport and Bossier City has the details.
• Insurance. Request certificates for general liability and workers' compensation, sent straight from the insurance agent, not handed over as a photocopy.
• Everything in writing. System, thickness, insulation, attachment, flashing details, how hidden damage is priced, payment schedule, warranty terms and cleanup.

Care tips for rubber roofs

Walk the roof or have it walked twice a year, looking at seams, inside and outside corners and pipe boots. Clear pine straw and leaves from drains. Keep sharp objects, grills and grease away from the membrane, since petroleum products and animal fats can damage EPDM. Fix small seam openings early, before water travels under the sheet.
