Finding a Roof Leak: Step-by-Step Water travels far from the entry point—how to trace ceiling stains to the actual roof penetration. Attic inspection techniques during and after rain.

Hail Damage to Roof: Assessment Guide Bruising vs cracking vs granule loss—what hail damage looks like on different materials. Why you need photos within 48 hours and the insurance claim filing window.

Wind Damage: Lifted & Missing Shingles Creased vs torn shingles, wind-rated shingles explained (Class D, F, H), and why wind damage often creates openings you can't see from the ground.

Ice Dams: Causes, Damage & Prevention Heat loss through attic melts snow at the ridge; water refreezes at the eave creating a dam. Ice & water shield, ventilation, and insulation solutions explained.

Sagging Roof: Structural Warning Signs Ridge sag vs rafter sag—both signal structural failure. Water damage to decking, undersized rafters, or foundation settlement could be the root cause.

Moss & Algae on Roof: Damage or Cosmetic? Gloeocapsa magma algae causes those black streaks—zinc strips and copper granules inhibit regrowth. Moss lifts shingles and traps moisture; removal must not damage granules.

Flashing Failure: The #1 Leak Source Chimney, valley, step, and pipe boot flashing—why improper flashing causes more leaks than shingle failure. Proper installation techniques and sealant lifespan.

Roof Decking Rot: Hidden Damage Below Shingles Spongy roof feel when walking, visible sagging between rafters, and why a tear-off reveals what a layover hides—decking replacement adds $2-5 per sq ft.
