What 60 mph Winds Mean for Your Home
The National Weather Service explains that when winds are sustained at 40–50 mph isolated wind damage is possible, while higher wind speeds can cause widespread significant damage. A severe thunderstorm warning is issued when winds are 58 mph or higher. During the December 18th storm, radar indicated wind gusts around 60 mph—strong enough to rip off shingles, crack siding and snap large tree branches.
Straight‑line winds—thunderstorm winds that do not rotate like tornadoes—can exceed 100 mph. They can produce damage similar to a low‑end tornado. According to the National Hurricane Center’s Saffir‑Simpson scale, even Category 1 hurricane‑force winds of 74–95 mph can damage roof shingles, gutters and siding and topple shallow‑rooted trees. Though the December 18th storm did not reach hurricane strength, 60 mph gusts fell squarely within the range known to cause roof damage and power outages.
The evidence is clear: Knoxville, TN Wind Damage from 60 mph gusts is serious, and homeowners should not dismiss minor signs of damage.
How High Winds Damage Roofs and Homes
Uplift and Suction
As wind flows over a roof, it creates uplift—a suction force that pulls shingles and decking upward. When gusts reach 60 mph or more, this suction can pry up shingles or break the bond between shingles and underlayment. Exposed seams allow rain to infiltrate. Even if shingles appear intact from the ground, loosened fasteners or torn sealant strips may become leak points during the next storm.
Wind also creates pressure differences around corners and edges. Eaves, ridges and rake ends are most vulnerable; high pressure on windward walls combines with low pressure on leeward sides to twist roof planes. Over time repeated gusts can loosen flashing around chimneys and vents.
Water Intrusion and Hidden Damage
The most insidious form of Knoxville, TN Wind Damage happens when wind loosens roofing materials just enough to allow water intrusion. Rainwater can seep into attic spaces, saturate insulation and eventually drip into living spaces. Wet insulation loses its thermal value, leading to higher energy bills. Moisture trapped in attics can foster mold growth and wood rot. Because these issues may take months to become visible, insurance adjusters might later argue that the damage is due to neglect rather than the storm. That is why early documentation is critical
Debris Impact
During the December 18th storm, downed trees and flying debris caused some of the worst Knoxville, TN Wind Damage. Fallen branches punched holes in roofs, while airborne objects like patio furniture or shingles from neighboring roofs acted like projectiles. The National Weather Service warns that straight‑line winds can blow objects around and pose a significant threat to safety.
Even small debris can bruise asphalt shingles or chip away protective granules, shortening the roof’s lifespan. After any wind event, homeowners should check around their yard for stray shingles or roofing nails; these can signal unseen roof damage.
Your Roof Might Be Damaged Even Without a Leak
Many Knoxville homeowners looked up after the December 18th storm and saw no obvious problems. However, Knoxville, TN Wind Damage often hides beneath shingles or within attic spaces. Here’s why you might still have a valid insurance claim:
- Lifted or creased shingles: When wind catches the edge of a shingle it can bend or crease it. Creasing breaks the shingle’s seal and weakens it. Even if the shingle lies back down, its bond is compromised.
- Granule loss: Debris and friction can strip protective granules from shingles. Without granules, shingles deteriorate faster and become more susceptible to UV damage and leaks.
- Flashing damage: Wind‑driven rain can work under flashing around vents, chimneys or skylights. Loosened flashing may not leak until the next heavy rain.
- Hidden attic leaks: Water can enter around nails or seams, run down rafters and saturate insulation without dripping into living spaces right away.
Because of these factors, homeowners should not rely solely on visual inspection from the ground. A professional roofing contractor like Litespeed Construction uses chalk tests, moisture meters and drone imagery to detect subtle damage.

The Complexity of Insurance Claims
Navigating a roof insurance claim after Knoxville, TN Wind Damage can be daunting. Insurance policies often contain intricate wording about coverage limits, deductibles, depreciation and exclusions.
