The 5 issues we see across Huntsville, Madison, and Decatur more than anywhere else.
Algae streaking
Tennessee Valley humidity feeds algae. Modern AR-granule shingles slow it down.
Hail bruising
North Alabama is in an active hail belt. Bruising is often invisible from the ground.
Wind creasing
Spring straight-line winds break shingle seal strips on a regular basis.
Pipe boot failure
The #1 leak source we find — rubber gaskets that crack within a decade.
Inadequate ventilation
Many older Huntsville homes lack proper ridge ventilation, cooking shingles from below.

Local Factors That Change Roofing Problems Common in North Alabama 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
- 1Save any debris, torn shingles, or broken material for the record.
- 2Check ceilings and closet corners across the whole house, not just the room where you saw a stain.
- 3Ask your insurer what your wind-and-hail deductible actually is before you decide to file.
- 4Book an inspection that produces slope-by-slope photos you can keep.
- 5Schedule the permanent repair rather than relying on sealant as a long-term fix.
