Interlocking Metal Roofing Panels for Wind Resistant Roofing

May 30, 2018

wind resistant roofing from Lifetime Metal Roofing of ATL

Strong winds are prevalent everywhere, but here in Atlanta, we also receive those strong winds as the residual of hurricanes. Though the strength of those storms weaken over the miles that they travel, it’s not unusual these days for homeowners in Georgia to experience winds in excess of 80 mph during the hurricane season.

 Wind resistant roofing in the form of our interlocking metal roofing panels, when chosen and installed correctly, can withstand even hurricane strength winds.

Conventional Roofing: Asphalt Shingles and Wind Resistance

Conventional roofing materials depend upon three things to hold them tight in high winds: 

  1. Their own rigidity, which diminishes with age.
  2. Their weight and gravity.
  3.  Failure-prone sealants.

A Different Approach: Classic Wind Resistant Roofing

The very interlocking nature of metal roofing makes it an ideal system that has panels which interlock on all sides and edges.

Traditional shingles overlap and really don’t have anything to hold them in place. Though they may appear to “interlock”, asphalt shingles are easily compromised by heat and cold temperatures. Those tiny, “interlocking” flaps simply can’t hold up to wind, rain, hail, or snow load. Those tabs break.

Our exclusive Classic Metal Roofing Systems deliver rigidity. Most roofing materials lose wind resistance with age as they become more brittle and as sealants begin to dry out and fail. Metal roofs, though, resist this kind of degradation with weather exposure and instead maintain their wind resistance even as they age.

Because of the interlocks between our panels, air can pass between them. This means that the roof covering alone does not bear the entire brunt of the uplift pressures on the “back” side of the roof.
