EPDM Commercial Roofing in Shreveport, LA
EPDM Rubber Roofing for Older Shreveport-Bossier Buildings
EPDM has been on Shreveport-Bossier commercial roofs for a long time, and a lot of the manufacturing and older office buildings we work on still carry an original ballasted or fully adhered EPDM system installed decades ago. Whether you need a patch, a partial section replacement, or a full tear-off and re-install, we work this material regularly enough to know exactly where it tends to fail first.
Where EPDM Actually Fails on These Roofs
Almost every EPDM failure we get called out for starts at the seams. The old seam tape used on installations from the 1990s and early 2000s loses its bond over time, especially at flashing details around HVAC curbs and parapet walls. By the time a tenant reports a ceiling stain, the seam has usually been letting water in for months, tracking laterally across the insulation before it ever shows up inside the building. We check every lap and flashing detail during an inspection, rather than only the areas near the reported leak.
Ballasted systems add another variable: displaced stone from wind events can expose membrane to UV it was never meant to see uncovered, accelerating breakdown in spots you wouldn't expect.
Patch, Partial Replace, or Full Reroof
We don't default to a full tear-off just because a roof has a few problem seams. If the membrane elsewhere is still flexible and the deck is dry, resealing and re-taping failed seams can add years of service life for a fraction of replacement cost. Where the membrane has hardened and cracked across large sections - usually from age and repeated UV exposure - a section replacement or full reroof becomes the more honest recommendation. We'll walk the whole roof with you and point out exactly which category each area falls into.
Black EPDM Versus White EPDM in This Climate
Standard black EPDM absorbs heat, which can work in its favor during Shreveport's shorter winter but adds real cooling load through the long, humid summer. White EPDM reflects more solar heat and can reduce rooftop surface temperatures noticeably, which matters for buildings with rooftop-mounted HVAC or refrigeration equipment working hard through July and August. For manufacturing buildings running process equipment that's sensitive to ambient heat, that difference is worth discussing before you commit to a color.
Ballasted, Mechanically Fastened, and Fully Adhered Systems
- Ballasted EPDM held down with stone or pavers, common on older heavier-deck buildings
- Mechanically fastened EPDM using plates and fasteners through the membrane
- Fully adhered EPDM bonded with adhesive for wind-exposed or lightweight-deck buildings
- Seam reinforcement using cover tape at high-stress laps and T-joints
- Perimeter and curb flashing detail work, the most common repair point
We'll match the attachment method to your deck type, wind exposure, and whatever loading restrictions your building has - a ballasted system isn't an option on a roof that can't carry the extra dead load, for example.
What a Facilities Manager Should Know Before Approving Repair Work
If your roof is older EPDM and you're getting periodic leak calls, ask for a full-roof condition assessment before authorizing spot repairs. Spot repairs that chase individual leak reports without a broader look at seam condition tend to become a recurring line item on your maintenance budget, one small invoice at a time, without ever addressing the roof's actual remaining service life. A single assessment gives you a clearer number to bring to whoever approves capital spend.
Recovering an Aging EPDM Roof Instead of Full Tear-Off
EPDM doesn't always need to come off entirely once it starts showing age. If the membrane field is still generally sound and the failures are concentrated at seams and flashing, a new membrane can sometimes go down as a recover layer over the existing EPDM, provided the deck and insulation test dry underneath. That approach saves the cost and downtime of full tear-off while giving you a fresh, warrantied surface going forward.
We check this option on every older EPDM roof we inspect, because a lot of facilities managers assume replacement is the only path once a roof passes a certain age, when recover is often still on the table. A number of the manufacturing plants we service in Shreveport-Bossier have also added rooftop equipment over the years - exhaust fans, condenser units, ductwork - that wasn't part of the original EPDM installation. Each addition means new penetrations and new flashing details, and those add-on penetrations are disproportionately where we find leaks during inspection. If your building has had equipment added to the roof at any point, those spots deserve extra attention regardless of how old the rest of the membrane is.
Common Questions About EPDM Roofing
Our roof has EPDM from the 1990s - is it worth repairing or should we replace it?
It depends on membrane flexibility and how widespread the seam failures are. We'll give you a section-by-section read so you're not guessing.
Can EPDM be recovered instead of torn off?
In some cases, yes, depending on deck condition and local code limits on how many roof layers a building can carry. We'll confirm during inspection.
Does ballasted EPDM work on every building?
No - it depends on structural capacity for the added ballast weight. We check that before recommending a ballasted system.
How often should EPDM seams be inspected?
We recommend at least an annual walk, plus a check after any significant wind or hail event, since seam and flashing failures are rarely visible from the ground.
Is white EPDM worth the extra cost over black?
If you're running heat-sensitive equipment on the roof or trying to cut summer cooling costs, often yes. We can walk through the numbers for your specific building.
