by | Apr 1, 2023 | Blog, Central Missouri, Knob Noster, Local News, Storm Damage Roof

On Friday, residents in Knob Noster experienced severe weather in the beginning of what is shaping up to be a doozy of a storm season. Here’s the overview of what occurred:

  • What: 1.75 inch diameter hail
  • When: March 31, 2023
  • Where: Knob Noster, MO

What It Means for Your Home

The Johnson County Emergency Management Agency posted on their Facebook page that areas of Knob Noster saw hail as big as 1.5″ in diameter while residents throughout the area reported even larger hail in the range of 1.75 to 2 inches in diameter.


Clearly, that’s some huge hail – but what exactly does that mean for your home?

Generally hail that is greater than 1″ in diameter will cause damage and warrants a professional inspection.

  • Hail this size can create dents in shingles as well as bruising in the underlayment.
  • You may see dents in your gutters and fascia.
  • Siding can become dented or even cracked.
  • Hail can tear holes in window and door screens.
  • Shingles will experience granule loss – this will be obvious from an excessive amount of granules in your gutter downspouts.

Larger hail, in the ranger of 1.5″ to 2″ in diameter is even more destructive.

  • In addition to the above problems, hail of this size can begin to penetrate softer parts of the roof like ridge caps and plastic roof vents.
  • Siding is more likely to crack and break – you may even see your siding tear off entirely from the combined pressure of hail strikes and high winds.
  • Windows and doors may show cracks in their glass from hail impacts.
  • Most metal fixtures will begin to show damage.

Take note, larger hail is generally caused by stronger winds – wind can be extremely damaging in its own right.

  • High winds will cause shingles to lift, curl, peel, or blow off the roof entirely.
  • Fallen limbs and other debris can cause extreme damage to the roof, siding, gutters, and other exterior fixtures.
