Commercial roofing for Houston grocery stores and supermarkets. Reroofing and leak repair that protects refrigeration, inventory, and rooftop HVAC units.

Roofing over a store that never stops selling perishables
A grocery store roof is working overtime in ways an ordinary commercial roof is not. It carries a dense field of rooftop equipment, it sits over millions of dollars of perishable inventory, and the store underneath stays open while we work above it. We reroof and repair grocery stores and supermarkets across Greater Houston with all three of those pressures in mind, keeping the sales floor open, the refrigeration running, and the produce dry while the new roof goes on.
Most supermarkets in Harris County are large, flat, single-ply roofs over a big open box. That wide flat expanse is exactly the kind of roof Houston weather goes after, and the equipment density on top of a grocery store makes every leak more likely to land somewhere expensive.
The rooftop equipment makes the roof harder
Walk a Houston supermarket roof and you are walking through a small mechanical plant. Refrigeration condensers, multiple large HVAC rooftop units, exhaust fans over the bakery and deli, and a web of refrigerant lines, condensate drains, gas lines, and conduit running across the membrane. Every one of those is a roof penetration, and every penetration is a potential leak.
This density drives the specific problems we see on grocery roofs:
Failed penetration seals. Refrigerant line sets and condensate lines move and vibrate, and the pitch pockets and seals around them dry out and crack under Houston sun, opening leaks right next to running equipment.
Leaks over refrigeration and electrical. Because so much of the rooftop equipment serves the cold cases, a leak in the wrong spot can drip onto a condenser or into an electrical disconnect, turning a roof problem into a refrigeration outage and a spoiled-inventory loss.
Ponding around curbs. Water collects on the low side of large rooftop units and in the valleys between them. On Houston's flat decks with heavy rain, that standing water sits for days and wears the membrane out fastest exactly where it is hardest to reach.

Roof planning guidance

Heat and UV breakdown. The sheer size of a supermarket roof means a huge area baking under months of Gulf Coast sun, drying and embrittling an aging membrane until it splits. We work around your equipment, not just over it Reroofing a grocery store means coordinating closely with whoever services your refrigeration and HVAC. We protect the running equipment during the work, keep refrigerant and condensate lines supported and functioning, and reflash every penetration properly so the new roof seals tight around the dense field of curbs and pipes. Where units have to be lifted or curbs rebuilt, we coordinate the timing so a cold case is never left without the cooling it depends on.

Because the store stays open, we keep the work clean and contained. We protect against debris reaching the sales floor through rooftop openings, we manage where crews and materials stage so customer parking and entrances stay clear, and we tarp and seal any open area at the end of every workday. A single overnight Houston downpour reaching the grocery aisles or a stockroom is the exact outcome we plan to prevent.

Reflective roofs that cut the refrigeration load

Heat is not just a roof-durability issue on a supermarket, it is an operating-cost issue. The more heat the roof absorbs, the harder the refrigeration and HVAC have to work, and a grocery store runs those systems constantly. On the flat roofs that cover nearly all Houston supermarkets, we install reflective white single-ply membranes such as TPO, which bounce a large share of the sun's heat back off the building. Under the months of intense Houston sun, that reflectivity eases the load on the rooftop units and the cold cases below, which matters on a building this size.

Roof systems we install on Houston supermarkets

For most grocery reroofs we install reflective TPO or PVC single-ply membranes, sized and attached for the wind exposure this region sees during hurricane season. PVC in particular stands up well to the grease and exhaust that drift onto the membrane near bakery and deli vents, which is a real factor on a food retail roof.

Where the existing membrane still has life but is weathering, a spray-applied silicone or acrylic coating can restore reflectivity, seal the aging seams and penetration details, and add years to the roof without a full tear-off. For a busy store, a coating's lower disruption and faster schedule are often the deciding advantage, since there is no demolition phase exposing the sales floor below.

Solving the drainage and ponding problem

Storm response, repairs, and inspections

A flat supermarket roof has to move a great deal of water fast when a Houston storm parks overhead. We assess the drains and scuppers, clear and enlarge undersized outlets, and add tapered insulation to build slope toward the drains and around the equipment curbs where water collects. Correcting the ponding around rooftop units does two things at once: it ends the chronic leaks in those low spots and it removes standing water from right next to the equipment you cannot afford to lose. Grocery roofs take a beating in this climate, and not every problem is a full reroof. We repair active leaks, reseal and rebuild failing penetrations, reflash equipment curbs, and patch storm punctures when the roof still has years left in it. Spring hail and hurricane-season wind both damage large single-ply roofs, and after a major storm moves through the Houston area we inspect supermarket roofs and document the damage, which gives you the record you need for an insurance claim and a clear picture of what to repair before the next leak finds your inventory.

We also offer scheduled inspections so the penetration seals, drains, and membrane get checked before hurricane season rather than after a leak hits a cold case. For a building where a roof failure can mean lost refrigeration and spoiled product within hours, staying ahead of the roof is far cheaper than reacting to it.
