What's Included
Flat Roof Replacement in The Woodlands, TX
Full Tear-Off Replacement
We strip the failing membrane down to the deck, remove any wet or rotted insulation underneath, and start the new system on solid, dry decking.
TPO, PVC, and Modified Bitumen Systems
Single-ply and modified bitumen membranes from Duro-Last and Versico, matched to your building's slope, drainage, and rooftop traffic.
Drainage and Insulation Correction
Tapered insulation, added drains or scuppers, and corrected slope so water actually leaves the roof instead of sitting on it.
Commercial and Residential Flat Roofs
Offices, retail buildings, and warehouses make up most of our flat roof work, with occasional replacements on flat-roofed additions, porches, and modern-style homes.
Minimal Disruption During the Tear-Off
Work staged in sections, materials staged away from entrances, and a crew that keeps your building watertight overnight during multi-day projects.
Locally Owned and Operated
ROYH Build Co serves The Woodlands and Magnolia, TX, and works directly with property managers, general contractors, and homeowners across the region.
Signs Your Flat Roof Needs Replacement, Not Another Repair
Every flat roof gives warning signs before it fails outright, and most of them show up long before the ceiling starts dripping. Chronic ponding water is usually the first one. A little standing water after a hard rain is normal on a low-slope roof. Water that is still sitting there two or three days later is not, and it means the roof has lost its slope or the drains are not doing their job anymore. Left alone, that ponding accelerates membrane breakdown right where the roof is weakest.
Saturated insulation is the sign most building owners never see until a repair crew opens the roof up. Once water gets under the membrane, insulation boards soak it up like a sponge and stop insulating at all, and a roof deck that feels soft or spongy underfoot is often telling you the insulation below it is already gone. Repeated leaks are the third flag. If the same spot keeps reopening after a patch, or new leaks keep showing up in different areas of the roof, the membrane itself has reached the end of its service life. Our flat roof repair service handles the early-stage version of these problems. Once ponding, saturation, and repeat leaks are all showing up together, replacement is usually the more honest answer.
Membrane Options: TPO, PVC, and Modified Bitumen
We install three main flat roof systems, and which one makes sense depends on the building. Our TPO roofing uses Versico and Duro-Last membranes, a reflective single-ply system that is heat-welded at the seams and holds up well against UV exposure and the heat cycling a Texas roof sees every summer. It is the most common choice for offices, retail buildings, and warehouses.
For buildings with more demanding conditions, restaurants with grease exposure, sites near heavy chemical use, or roofs that see a lot of rooftop foot traffic, we install PVC roofing instead. PVC membranes cost more than TPO but resist punctures, chemicals, and grease better over the life of the roof. Modified bitumen is the third option, a multi-layer asphalt-based system that is heavier and holds up well on roofs with a lot of rooftop HVAC equipment or regular maintenance traffic. We walk every roof before recommending a system. The right membrane depends on your building's use and roof traffic, not just what is cheapest to install.
Getting Drainage and Insulation Right the Second Time
A flat roof replacement is a chance to fix the underlying problem, not just swap out the membrane. Most flat roof failures trace back to drainage that was never right in the first place, not the membrane material itself. During a replacement, we install tapered insulation to build in a real slope where the roof deck is flat, add drains or scuppers where the original design left too few, and correct any low spots that were letting water collect year after year. Wet or rotted insulation gets pulled out entirely rather than covered over with new membrane on top of a soggy base. Skipping that step is how a roof ends up back on the repair list within a few years of a full replacement.
Flat Roof Replacement for Commercial Buildings and the Occasional Home
Most of our flat roof replacement work is on commercial buildings, offices, retail centers, restaurants, and warehouses across The Woodlands and the greater Houston area. We also take on flat roof replacements on homes when the layout calls for it: flat-roofed additions, covered porches, garages, and the modern-style homes that use a low-slope roof section as part of the design. The membrane systems and installation approach carry over from commercial work either way. What changes is the scale of the job, not the quality of the system going on the roof.

Frequently Asked Questions
How do I know if I need a flat roof replacement instead of a repair?
If your roof has one isolated leak or a small area of membrane damage, repair is usually enough. Replacement becomes the better option once you are dealing with chronic ponding water that will not drain, saturated or soft insulation, or leaks that keep reopening in the same spot or moving to new ones after being patched. We walk the roof in person before recommending either option.
What is the difference between TPO, PVC, and modified bitumen for a flat roof replacement?
TPO and PVC are both single-ply membranes that are heat-welded at the seams. TPO is a reflective, cost-effective option well suited to most commercial buildings, while PVC resists chemicals, grease, and punctures better, which makes it a common choice for restaurants and industrial sites. Modified bitumen is a heavier, multi-layer asphalt system that holds up well on roofs with a lot of rooftop equipment or foot traffic. We help match the system to your building before you commit to one.
How long does a flat roof replacement take?
Timelines depend on the size of the roof, the extent of any deck or insulation damage found during tear-off, and the weather. Smaller commercial roofs can often be completed in a few days, while larger buildings or roofs with drainage corrections built in take longer. We give you a schedule estimate up front once we have walked the roof and can see what condition the deck is in.
Do you replace flat roofs on homes, not just commercial buildings?
Yes. While most of our flat roof replacement work is on commercial buildings, we also replace flat roofs on homes with flat-roofed additions, covered porches, garages, or modern-style designs that include a low-slope section. The same TPO, PVC, and modified bitumen systems we install commercially apply to residential flat roof sections.
