Collin County hail on complex roofs
Collin County takes the same North Texas hail as Dallas does, but the roofs it lands on are different. McKinney's rapid growth since the 1990s means a housing stock dominated by large two-storey homes with steep pitches, multiple intersecting gables, dormers and long valleys.
Complex geometry cuts both ways for storm damage. Steep pitches shed hail at a more glancing angle, which reduces impact severity somewhat. But the same geometry concentrates water volume in valleys, so when something does fail near a valley, the volume of water reaching the breach is far higher than on a simple gable roof.
Most of this stock carries architectural shingle, some of it impact-rated, which performs better than the three-tab on older Dallas housing — but at larger stone sizes it still fails.
Complex roofs take longer to cover properly
A tarp on a simple gable is one plane and four edges. A tarp on a McKinney roof with a dormer and a valley running through the damage zone is several planes, more edges and a set of transitions that each need detailing. It takes longer, and a crew that rushes it leaves a cover that channels water into the valley rather than out of it.
Where damage crosses a valley, we generally cover both planes and run the overlap so the upper sheds onto the lower rather than butting them at the valley line. Steep pitch also means fall protection and often roof jacks, which adds setup time before any tarp goes down.
We cover McKinney along with the surrounding Collin County communities — Allen, Frisco, Prosper, Melissa and Princeton.
