Austin Commercial Roofing Restoration
Austin commercial roofing restoration puts a new, fully adhered waterproofing layer over a roof that is aging but still sound, instead of tearing it off. Done on the right roof it adds years for well below the cost of a replacement. Done on the wrong roof it traps water and hides the problem. Which roof you have is a measurement, not an opinion.
What commercial roof restoration actually means
Restoration means repairing a roof's weak points (seams, flashings, penetrations, wet areas) and then applying a liquid-applied coating system across the whole surface, built up to a specified thickness. The existing membrane stays in place and becomes the substrate. It is not a paint job and it is not a new roof covering. The coating does the waterproofing only as well as the repairs and preparation underneath it.
It sits between a Commercial roof repair Austin visit, which fixes defined problems, and a Commercial roof replacement in Austin, which removes the system. For how the four options compare side by side, see Austin commercial roofing solutions.
Restoration only works on a dry roof
The single most important question is how much of the insulation under the membrane is wet. Coat over saturated insulation and you seal the water in: the deck keeps degrading, the insulation keeps losing R-value, and the coating blisters from below. So before anyone quotes a restoration, the roof needs a moisture survey and core cuts to confirm what the survey shows.
Infrared or capacitance scan
Wet insulation holds heat differently. A survey maps suspected wet areas across the whole roof, not just where the leaks are.
Core cuts
Small cores through the membrane confirm what the survey suggests, and show the layers, the insulation and the deck.
The quarter rule
Isolated wet areas are cut out and replaced before coating. If roughly a quarter or more of the roof is wet, restoration stops making sense.
Ask every bidder one question: "Where is your moisture survey?" A restoration quote without one is a guess about the most important variable on the job, and guesses in this trade are usually optimistic.
Silicone, acrylic and urethane compared
| Coating | Where it fits | Watch for |
|---|---|---|
| Silicone | Roofs with some ponding; holds up well to UV in Central Texas sun; reflective white finish | Collects dirt, which lowers reflectance over time; very few materials bond to silicone later, so future recoats are usually silicone again |
| Acrylic | Well-drained roofs; a reflective, economical choice | Not suited to standing water; ponding areas need correction or a different coating |
| Urethane | Higher foot traffic, rooftop equipment areas, impact resistance | Often used as a base or in combination; typically costs more |
The right coating depends on the substrate (TPO, EPDM, modified bitumen, built-up or metal), the drainage and the traffic. Restoration coatings are made for low-slope and metal roofs; a steep-slope shingle roof needs a different approach, covered on Austin commercial shingle roofing. For the drainage question, see flat roof installation contractor in Austin, which covers slope, crickets and ponding in detail.
How a commercial roof restoration is done
- Inspect, survey and core. Moisture survey across the whole roof, confirmed with core cuts.
- Cut out and replace wet areas. Wet insulation and damaged membrane are removed and replaced with matching materials.
- Repair the details. Seams, flashings, penetrations, curbs and drains are repaired and reinforced, often with fabric embedded in the coating.
- Clean and prime. The surface is cleaned, and primed where the substrate needs it for adhesion.
- Apply to a measured thickness. The coating goes on to the specified mils, and thickness is checked during application, because the warranty depends on it.
- Final inspection and warranty. Walk-down, punch list, documentation, and warranty registration where applicable.
When restoration is the wrong answer
Wet roof
More than roughly a quarter of the insulation wet, or a deck that's deteriorating.
Structural ponding
Water that sits because of the slope or the deck, not a blocked drain. Fix the geometry first.
Failing membrane
Shrinking, splitting or delaminating across the field. Coating won't hold it together.
Near end of life, but dry
Often the best candidate: sound, dry, and aging. This is where restoration earns its keep.
On taxes: restoration is sometimes treated differently from a replacement for tax purposes, but that depends on your situation. Ask your accountant before deciding on that basis; we won't tell you what your treatment will be.
After restoration
A coated roof still needs inspection: drains cleared, penetrations checked, and any mechanical damage from HVAC service repaired before it lets water under the coating. Put it on a Commercial roof maintenance in Austin plan from day one. To start with the survey, book a Commercial roof inspection Austin, or see how we build a number on our Austin roof estimate page.
