Bars to one scale; the longest is spring (March to May).

By heavy-rain days, Hennessey falls among the fewest heavy-rain days of the 227 places in Oklahoma on this site (10.4 a year). Its housing ranks near the middle of the 227 places in Oklahoma on this site (half built by 1974). By first frost it falls 34th earliest for the first fall frost of the 226 places in Oklahoma on this site (October 30).

When to clean gutters in Hennessey

The first fall frost comes around October 30 in a typical year here, and the last spring frost around April 14 (median dates, NOAA normals). A fall cleaning set for the weeks after that frost, when the branches over the house are bare, gets the year’s leaves in one trip; a spring visit follows once the pollen and catkins have come down.

When to clean gutters explains how the trees over a roof change the schedule.

Gutter and downspout size for Hennessey rain

Gutters are sized for the worst few minutes of a storm, not for the year. In Hennessey the five-minute rain expected about once in ten years falls at 8.06 inches an hour (NOAA Atlas 14 Volume 8). At that rate one 2-by-3-inch downspout drains about 890 square feet of roof and one 3-by-4-inch downspout about 1,790, by the rule in the Copper Development Association’s design handbook. Try your own roof in the gutter and downspout calculator, which starts from this figure.

The houses in Hennessey

Half the homes in Hennessey were built by 1974, 70% before 1980 (ACS 2020–2024). At that age a gutter has seen decades of leaves and storms, and the fascia it hangs from has too. On a house built before 1978, replacing more than 20 square feet of painted fascia or trim falls under the EPA’s lead-safe rule, so ask whether the crew is certified.

64% of households own their home, and 75% of homes are detached houses, 4% townhouses. If an association maintains the exterior, the gutters may be its job rather than yours; check before calling.

Hiring in Oklahoma

Licensing for gutter work differs from state to state; ask a contractor in Hennessey which license or registration they hold in Oklahoma, and for proof of liability insurance. Hiring a gutter contractor
