A yearly plan for a commercial roof
Spring walk
Before the stormy months, clear drains, scuppers and gutters and check seams and flashing.
Post-storm checks
After hail or high wind, walk the roof and photograph any damage.
Fall walk
Clear leaves and debris, and check rooftop units and curbs.
Fix small issues fast
Open seams and loose flashing are cheaper to fix than wet insulation.
Budget ahead
Track repairs so you can see when replacement becomes the better spend. See our guide to a commercial roof maintenance plan.
Hail and commercial roofs in Tyler
Tyler sits in Smith County. NOAA's Storm Prediction Center logged 67 hail reports within 10 miles of the city from 2015 through 2024, and 18 of them were 1.75 inches or larger. The largest, 2.75 inches, came on June 13, 2023. Large hail was reported in 7 of the 10 years.
On a flat roof, hail damage is easy to miss. A membrane can be bruised or punctured with no visible sign from the ground, and water can spread under the surface before it shows on a ceiling tile. With large hail that frequent, a post-storm walk should be part of the routine, not an afterthought.
Heat adds to the problem. A flat roof faces the sun on its whole surface, and daily expansion and contraction stress seams, flashing and fasteners. A membrane worn by years of sun is more likely to puncture under hail than a newer one. Rooftop units add risk, since technicians walk the roof and every curb and pipe is a place where water can get in.
Roof systems on commercial buildings
TPO and EPDM membranes
Single-ply sheets used on many flat roofs. Our TPO vs. EPDM guide compares them.
Modified bitumen and built-up
Layered systems common on older buildings. Watch for blisters, cracks and open laps.
Metal
Used on many shops and warehouses. Fasteners, seams and rust are the main concerns.
Mixed roofs
Some buildings combine steep sections with flat areas behind parapets, each needing its own approach.
Rooftop penetrations
HVAC curbs, pipes and drains break the membrane. Flashing at each one is a frequent source of leaks.
Signs a commercial roof needs attention
Water that stays on the roof long after rain stops. See flat roof drainage systems.
Stained or sagging ceiling tiles.
Lifted seams, cracked flashing at walls or curbs.
Rust, loose fasteners or open seams on metal panels.
Repeated leaks in the same area after repairs.
Ponding around rooftop units or at low spots near drains.
Debris and branches left on the roof after storms. See tree limbs and debris roof damage.

Frequently Asked Questions
How do I know if a flat roof leak is from hail or age?
Hail leaves bruises, punctures or fractures in a pattern across the roof, often with dented metal nearby. Age shows as worn seams, shrinking membranes and cracked flashing. An inspection with photos can separate the two, which matters for maintenance planning and any insurance conversation.
Can a commercial roof be repaired in sections?
Yes. Many flat roofs can be repaired or even replaced one area at a time, as long as the system is tied in properly where old meets new. Whether that makes sense depends on the condition of the rest of the roof and the insulation below.
What is a roof coating, and when does one make sense?
Coatings are a product category on the market that some owners use on sound roofs to add a surface layer. They do not fix wet insulation or failed decking. Any decision about a coating, a repair or a replacement should follow an inspection of the layers under the surface.
