Dallas summers hit 100 degrees and drive thermal expansion that cracks standard shingles fast. Class 4 shingles use a reinforced fiberglass mat and polymer modified asphalt to hold up. Cheap crews often skip the extra underlayment layer at eaves, which lets water back up under the first row during heavy rain.
Many homes in Oak Lawn and East Dallas still have 20-year shingles from the 2000s that fail at the ridge cap first. Switching to Class 4 means nailing down GAF Timberline HDZ or similar impact-rated product with 130 mph wind warranty. Dallas permits require the new layer to meet current wind load rules on any roof over 4:12 pitch.
Hail storms move through North Dallas and Lake Highlands every spring. Class 4 shingles limit granule loss so the roof keeps its fire rating longer. Crews that rush tear-offs often leave old nails in the deck, which poke holes in the new felt within two seasons.
