How the Glenn Heights hail record affects flat roofs
NOAA's Storm Prediction Center logged 95 hail reports within 10 miles of Glenn Heights from 2015 through 2024. Of those, 19 were 1.75 inches or larger, and the largest reached 4 inches on June 12, 2023. Large hail was reported in 2017, 2021, 2023 and 2024.
On a flat roof, hail damage hides. A stone can split a membrane, crack the board underneath or crush insulation, and the roof may look fine from below. Water then spreads under the membrane before it reaches a ceiling. With three of the large-hail years in the most recent stretch of the record, many commercial roofs in the area deserve a close walk now.
Glenn Heights lies in Ellis County and Dallas County, and buildings in both parts of the city face the same storm tracks.
Simple habits that extend a commercial roof
Keep drains, scuppers and gutters clear, especially before spring storms.
Walk the roof or have it checked after any storm with large hail.
Limit foot traffic on the membrane and use walk pads near equipment.
Fix small punctures and open seams quickly before water spreads.
Keep a written log of inspections and repairs. A commercial roof maintenance plan helps.

Repair now or plan a replacement
A commercial roof does not have to be replaced the first time it leaks. Open seams, failed flashing at units and small punctures can be repaired and the roof kept in service. The question is how much of the material underneath is wet or crushed. Dry insulation and a few failures point to repairs; wide wet areas point to a new system.
For owners on a budget, the best approach is often to fix what is urgent now and plan a replacement on your own schedule. That avoids an emergency job in the middle of storm season and gives time to compare membranes and drainage options. Our article on signs a commercial roof needs replacement lists what to watch.

Frequently Asked Questions
What is ponding water and why does it matter?
Ponding is water that stays on a flat roof long after rain. It adds weight, speeds up wear on the membrane and finds any small opening. Clogged drains, sagging decking or poor slope can cause it. Our guide on flat roof drainage systems explains the fixes.
Can a hail-damaged membrane be patched?
Small punctures and splits can often be patched with matching material. If the hail crushed insulation or cracked the cover board over a wide area, patching the surface will not fix what is underneath. An inspection shows how far the damage goes.
Do you work on church and small office roofs?
Yes. GemSco works on residential and commercial roofs, including pitched roofs with shingles or tile and low-slope or flat roofs. We look at the building, talk about how it is used and recommend repairs or replacement that fit.
