If a contractor steps on your roof and sinks, you have decking failure — not a shingle problem. Soft spots mean the OSB or plywood beneath has rotted, almost always from a slow leak that's been active for months or years.
Symptoms of Soft Spots on the Roof
- Roof feels spongy underfoot
- Visible dip or wave in roof plane
- Sagging between rafters
- Stains in attic on the underside of decking
What Causes Soft Spots on the Roof in North Alabama
- Slow hidden leak
- Long-term condensation from poor ventilation
- Failed flashing upstream
- Ice damming (rare in AL but possible)
Risks of Ignoring Soft Spots on the Roof
- Decking collapse under installer weight
- Inability to nail shingles properly
- Hidden mold colonies
- Possible truss damage if widespread
Why Soft Spots on the Roof Demands Quick Action
Across North Alabama, this problem rarely resolves itself — every rain, hailstorm, or windy afternoon makes the damage worse. Most homeowners who wait end up paying 2–4x more in interior repair, decking replacement, and mold remediation than if the roof was addressed in the first 30 days.

Local Factors That Change Soft Spots on the Roof in Huntsville
River-valley humidity across Madison, Morgan, and Limestone Counties feeds algae streaking and keeps decking damp after leaks. Moisture that lingers is what takes a minor flashing failure into rotted sheathing.
Local code matters too. Roofing work inside Huntsville city limits follows the International Residential Code as adopted locally, which sets nailing patterns, drip edge, underlayment, and attic ventilation minimums — and allows no more than two roof coverings before a full tear-off is required. When a roof is replaced, the new installation has to meet current code even if the old one predated it.
What to Do Next
- 1Write down when you first noticed the issue — carriers and contractors both ask for a date.
- 2Look for granules in gutters and at downspout outlets, which signals shingle wear or impact.
- 3Avoid climbing the roof yourself; wet or aging shingles cause most homeowner falls.
- 4Have the roof and attic inspected together, since half the useful evidence is underneath.
- 5Compare any two estimates line by line: underlayment, flashing, ventilation, warranty.
