How long does a built-up roof last on a commercial building in Houston?
A properly installed 3- or 4-ply commercial built up roofing system with a gravel cap typically lasts 20–30 years in the Houston climate, provided ponding water is addressed and the gravel ballast is replenished during routine maintenance.
What does commercial BUR roofing cost in Houston?
Commercial built up roofing projects generally start at $20,000 depending on square footage, tear-off scope, and drainage corrections. Final pricing follows an on-site inspection.
Why is ponding water such a concern for BUR roofs specifically?
Standing water adds sustained weight and moisture pressure at seams and flashing details. On a multi-ply commercial built up roofing system (BUR), prolonged ponding accelerates ply separation faster than it does on fully adhered single-ply membranes.
Can a built-up roof be repaired, or does storm damage always mean full replacement?
Most localized damage — a torn cap sheet, a failed flashing detail, or a bare gravel section on your commercial built up roofing — can be repaired in place. Full replacement is typically reserved for widespread ply separation or repeated leak history across the field.
How does gravel ballast affect a building’s cooling costs in Houston summers?
A light-colored or mineral-surfaced gravel cap reflects a portion of solar heat rather than absorbing it, which can reduce rooftop surface temperatures and ease HVAC load during peak Houston summer months.
Does a commercial BUR project in Houston require a permit?
Most commercial roof replacements in the Houston area require a permit through the applicable municipal or Harris County building department before work begins; repairs below certain thresholds may not. We confirm requirements during the estimate.
How can I tell if my flat roof is BUR versus modified bitumen or single-ply?
A gravel or mineral-surfaced top layer with visible asphalt between stones is the clearest indicator of a built-up roof, as opposed to the smooth membrane sheet look of TPO, EPDM, or PVC systems.
What causes blistering on a built-up roof’s surface?
Blistering occurs when trapped moisture or air between plies expands under sustained UV heat, common on Houston roofs during summer. Left unaddressed, blisters can crack open and expose the felt underneath.
How often should a commercial BUR roof be inspected?
Twice-yearly inspections — before hurricane season and after — catch gravel displacement, seam separation, and drain blockages before they become active leaks, particularly important given Houston’s storm frequency.
Will a new BUR system affect my commercial property insurance?
Some commercial insurers offer favorable terms for roofs with documented recent installation and warranty coverage. We provide installation and warranty documentation that can be submitted to your carrier.
Do you service BUR roofs outside Houston proper?
Yes — we serve Houston, The Woodlands, Cypress and more, with crews and materials staged at our Cypress supply yard for faster response across the service area.
What warranty comes with a commercial BUR installation?
Installations carry a 5-year workmanship warranty. Manufacturer material warranties vary by product line and are reviewed with you before the project is scoped.
