Ponding, pitch, and flat roof sections on DeSoto homes
Plenty of DeSoto homes have a low-slope section — over a patio cover, an addition, a porch, or a modern architectural element. These are where leaks start, and they fail differently than the main roof.
What we look for:
- Standing water 48 hours after rain. That's ponding, and it's a defect, not a quirk. Every day of standing water shortens the membrane's life.
- Shingles on a slope that can't carry them. Composition shingles have a minimum pitch. Below it they will leak no matter how well they're installed — the answer is a membrane system, not better shingles.
- The transition detail. Where the low-slope section meets the pitched roof is the highest-risk detail on the whole house, and it's the first thing a rushed crew gets wrong.
