The rules this check uses

Typical elastomeric/acrylic label requirements, applied to Wichita Falls's forecast above. Wind is stricter here than for any ground-level task — on a roof it's a safety limit.

Typical label thresholds for roof coating — the ruleset behind every Wichita Falls verdict above.
CheckThresholdWhy it matters
Air temperature 50–90°F Acrylic and elastomeric coatings want 50°F+ during application and initial cure.
Overnight low ≥40°F during the first 24 h Water-based coatings can be ruined by a cold, damp night before they skin over.
Dry before ≤0.05" rain in the prior 24 h; watch back to 48 h What fell before you start matters as much as what falls after — surfaces hold water invisibly.
Dry after <0.05" rain for 24 h after (48 h thick coats want 48 h) The make-or-break window: rain here undoes the work, not just delays it.
Evening dew-point spread ≥5°F from 6–11 pm Roofs radiate heat at night and hit the dew point before anything else in the yard.
Daytime humidity ≤85% Humid air slows evaporation, stretching dry times into the risky evening hours.
Wind ≤15 mph (roller only, no spray up to 20 mph) Scored on the windiest working hour; the marginal band changes the method, not the day.

Always follow your product label — formulas vary. Treat the table as the consensus range across brands — the label in your hand is the final word.

Figure 120 workable days a year in Wichita Falls, spread across March through May. Shoulder months turn on the overnight rule: an afternoon at 68°F passes, but the 40°F night floor is what actually opens the season in March. Neighboring towns shift by a month or more — the Texas comparison shows where Wichita Falls sits.

July here fails on heat, not rain: the average high of 97°F sits over the 90°F label ceiling, and 31 of 31 days typically top 90°F. Midsummer work moves to dawn or waits for October.

Ground level is more forgiving: compare exterior painting in Wichita Falls, where the same chemistry drops the roof-safety wind cap.

Climatology here is measured at Wichita Falls Muni Ap, Tx Us (8.6 km away). Treat the monthly numbers as the neighborhood average; a shaded north-side deck runs colder and damper than any of them. The exact formula lives in the methodology.

Wichita Falls by the numbers

Prep checklist

  1. Book a calm pair: under 15 mph to spray, under 20 mph to be up there at all, and 24 dry hours — October delivers 25 such days in an average Wichita Falls year.
  2. Walk the roof after the last rain (28% of May days here) and mark every ponding spot — they dry last and blister first.
  3. Wash the membrane, then give it a full Wichita Falls drying day; the 24-hour lookback applies to seams, not just the field.
  4. Tape the seams (seam tape) and give repairs their full cure — coating won't bridge a moving crack.
  5. Match roof primer to your membrane type before anything opens; compatibility beats optimism.
  6. Start at dawn and chase the shade line — Wichita Falls roof surfaces beat air temperature by 30°F+ in sun.
  7. Roll with a 3/4-inch nap roller kit at the label spread rate; thin coat today beats thick coat racing May rain.
  8. Harness on anything above a walkable slope, and quit by early afternoon — Wichita Falls's roofs reach the dew point first.

FAQ

What temperature do you need to apply roof coating?

50–90°F air with a 40°F+ first night — but the roof surface is the stricter limit: in sun it runs 30°F+ over air, so Wichita Falls's 97°F July afternoons can mean a 110°F membrane. First-light starts solve what the forecast can't.

How long does roof coating need to dry before rain?

Plan a 24-hour dry window per coat (48 when it's cool, humid, or laid on thick). The engine fails days that can't deliver it and flags the 24–48 h tail. Two thin coats on two Wichita Falls GOOD days beat one thick coat racing May rain.

Why does dew hit a roof first?

Radiational cooling: the roof faces the sky and sheds heat fastest, condensing moisture while the lawn is still dry. That's why this check is stricter in practice than the same rule for walls — Wichita Falls evenings that pass for paint can still wet a roof. Finish early.

Can you apply roof coating in high humidity?

The limit is ~85% relative humidity, and it stacks with dew: slow-drying film meets a roof that hits the dew point first on the property. Wichita Falls's drier months make this a non-check; muggy spells make dawn-to-noon the whole working day.

How windy is too windy to coat a roof?

15 mph ends spraying (overspray from roof height travels blocks); 20 mph ends the workday on safety grounds — the engine marks it NO no matter what else passes. Wind builds through the afternoon, one more argument for first light: that's how October banks its 25 workable Wichita Falls days.

What months are best for roof coating in Wichita Falls?

October, april and may, with October on top at 25 workable days (high 77°F, rain on 21% of days). The limiting rules here are summer heat on the membrane — see the table above.
