How low-slope roofs differ
A commercial roof usually has little pitch, so water drains slowly and depends on drains, scuppers and gutters to leave. If any of those clog, water sits. Standing water finds every seam, and a small split in the membrane can let a lot of it into insulation before anyone inside notices.
Most low-slope roofs use a single-ply membrane such as TPO or EPDM, a modified bitumen system or metal panels. Each has its own weak points. Our article on TPO vs. EPDM roofing compares the two most common membranes.
Heat is the quiet enemy. Long summer days make membranes expand and shrink, which stresses seams and flashing. Dark roofs hold more heat, and lighter membranes reflect more of it. When a roof is due for replacement, the choice of system and color is worth a real conversation, not just a price comparison. Our page on flat roof drainage systems is a good primer on the water side.
What we work on
Membrane repairs
Punctures, open seams and blisters are cleaned, patched and sealed.
Drainage
Clearing and correcting drains, scuppers and gutters so water leaves the roof.
Flashing and curbs
Edges and the base of HVAC units are where many flat roofs leak first.
Full replacement
When the membrane is worn out or the insulation is wet, we plan a new system with the least disruption.
Metal roofs
Fastener checks, sealant at seams and repairs to dented or rusted panels on metal buildings.
Hail and commercial roofs in Round Rock
NOAA's Storm Prediction Center logged 92 hail reports within 10 miles of Round Rock from 2015 through 2024, and 36 were 1.75 inches or larger. The largest, 4 inches, fell on September 24, 2023. Round Rock reaches into 2 counties, Williamson and Travis, and hail does not care about the line.
On a flat roof, hail can crush insulation under the membrane, crack older membranes and dent metal units and flashing. Damage is hard to see from the ground, so a walk-through after each large storm is the safest habit. Our hail damage roof repair in Round Rock page covers the storm side in more detail.
After a storm, a building manager can do a quick ground-level check: look for dented rooftop units, bent gutters and debris on the roof edge, then call for a full walk-through. Photos taken the same week make it easier to connect damage to the storm date.
Signs your building needs attention
Ponding water that stays after the rain has stopped.
Ceiling tiles stained inside the building.
Bubbles, cracks or open seams in the membrane.
Rust or loose metal at edges and around rooftop units.
Higher cooling bills that may point to wet insulation.
Wet or spongy spots underfoot when walking the roof.

Frequently Asked Questions
How often should a commercial roof in Round Rock be inspected?
Many owners schedule a check in spring and fall, plus one after any large hail or wind event. Regular checks catch clogged drains and open seams before they reach the insulation. A commercial roof maintenance plan keeps those visits on the calendar.
Can you work while my business stays open?
In most cases, yes. We plan the work in sections, keep entrances clear and talk with you about noise and access times. Our article on how to reduce business disruption during roof repairs explains what owners can plan ahead.
Is a coating a good option instead of replacement?
It can be when the membrane is still sound and the insulation is dry. A coating will not fix wet insulation or a roof with widespread damage. An inspection of the layers below shows whether a coating, a repair or a replacement fits the building.
