Monsoon bursts and desert wind
El Paso gets very little rain by Texas standards, and that is precisely what makes its storms dangerous for roofs. The bulk of annual precipitation arrives between July and September during the North American monsoon, in short, extremely intense bursts. A roof that has baked dry for ten months takes a year's worth of water in a handful of storms.
The second hazard is wind. Spring brings sustained high winds and dust storms through the Chihuahuan Desert, and those wind events regularly lift roofing material from low-slope roofs — where a lifted edge has no gravity assistance to reseat it.
Third, and specific to this corner of Texas: UV. El Paso's elevation and clear-sky fraction give it the most punishing ultraviolet exposure in the state. This matters directly for tarping, because a standard poly tarp degrades here faster than anywhere else in Texas. Anything expected to stay on for more than a few weeks needs UV-stabilised material as a matter of course.
Flat roofs change the method
Much of El Paso's housing and nearly all of its commercial stock is flat or low-slope — built up, modified bitumen, single-ply membrane, or the traditional adobe-influenced parapet roof. None of these shed water by gravity the way a pitched roof does, which means a tarp cannot simply be laid over a hole and left to drain.
Covers here are laid to direct water toward existing drains and scuppers, ballasted rather than fastened, and checked for ponding. A tarp that blocks a scupper on a parapet roof turns a contained leak into a flooded roof deck, which is a considerably worse problem.
