A tropical depression is a tropical cyclone with sustained wind speeds around 38 mph. So it’s pretty much like a big thunderstorm. Tropical storms have max sustained wind speeds are between 39 to 73 mph, and that can cause damage to roofs with loose shingles, tree branches too close to the roof, and some flying debris can penetrate some flat roof membranes.

Hurricanes are where the more serious damage occurs.

  • A category 1 hurricane has wind speeds from 74 to 95 mph. This can cause any loose shingles, siding, or gutters to fly off, and tree branches and trees to snap.
  • Category 2 hurricanes have winds 96-110 mph. Most three tab shingles have a wind resistance up to 90 mph, so severe damage can occur to roofs with that type of shingle. Flying debris and falling trees and branches can cause much damage to both shingle and flat roofs.
  • The wind speeds of a category 3 hurricane range from 111 to 129 mph. Most architectural shingles have a wind resistance of up to 110 mph, so these type of shingles can begin to blow off.
  • Cateogory 4 hurricanes have a wind rating of 130- 156 mph. Even you’re heavy duty designer shingles blow off with those winds.
  • A category 5 hurricane is going to render any roofing system you have susceptible to severe damage at best, and total lose at worst. There isn’t a whole lot to be done if this one hits your area.
