Solar Roof Integration in Houston, TX

• Putting Solar on a Houston Commercial Roof Without Voiding It
• The economics of rooftop solar make sense across Houston's commercial inventory. We have enormous, unobstructed flat roofs on warehouses, big-box stores, and office buildings, and we have the sunshine to match, with some of the highest solar irradiance of any major metro in the country. A distribution center off the Energy Corridor or a retail box in Westchase can carry hundreds of kilowatts on a roof that is otherwise dead space. The catch is that a solar array is a thirty-year mechanical and electrical system bolted to a waterproofing system that may not last that long, and the two have to be planned together or they fight each other.
• Our role is the roofing half of that equation. We make sure the membrane under the array is sound and will outlive a panel's first service interval, that the array is attached without compromising the watertight layer, and that putting solar up does not quietly void the manufacturer's roof warranty. Too many Houston building owners discover, after a leak, that a solar installer drilled their roof and that the membrane warranty is now worthless.
• Start With the Roof's Remaining Life
• The most expensive mistake in commercial solar is mounting an array on a roof with five years left in it. Removing and reinstalling a PV system to replace the membrane underneath can cost as much as the roof itself. Before anyone talks about panels, we assess the existing roof's condition and remaining service life. If it has a decade or more of sound performance left, we proceed. If it does not, we recommend re-roofing first, ideally with a reflective single-ply system that runs cooler and extends the life of both the membrane and the equipment above it. Coordinating the re-roof and the solar install on a single timeline is almost always cheaper than doing them years apart.
• Attachment Without Punctures
• How the array connects to the roof is the decision that determines whether you stay dry. We work with two broad approaches:
• Ballasted, non-penetrating racking. On many of Houston's low-slope membrane roofs, the array sits in trays weighted with concrete blocks and never pierces the waterproofing. Protection pads spread the load and shield the membrane from abrasion. This keeps the roof's integrity, and its warranty, fully intact. The constraint is wind and weight, which we address below.
• Mechanically attached mounts. Where ballast is not viable, attachments are fastened to the structure and then flashed. Here the detailing is everything. Each mount becomes a roof penetration, and we flash it with the same discipline we use on any pipe or curb, using manufacturer-approved bases welded or adhered into the field membrane so the array's footprint stays as watertight as the rest of the roof.
