7 Hidden Dangers You Never Spot from the Ground

Ground view = 20% effective. Here’s the real killers – with pics from our 35+ years.

#1-3: Shingle Sneaks

  1. Granule Loss: Looks “dirty”? Bald spots = UV fail. Test: Run hand over – gritty gone? Lifespan cut 50%.
  2. Curling Edges: Wind from Gloucester storms lifts ’em. Miss = water entry.
  3. Bald Spots: Hail/age. PAA: “What does hail damage look like?” See our guide.

#4-7: Flashing, Valleys, Gutters & Chimney Fails

  1. Flashing Cracks: #1 leak source (35%). Chimney/step – check sealant.
  2. Valley Damage: Water highway. Lift shingles – see tears?
  3. Gutters Pulling Away: Foundation killer. [Use our gutter sizing calculator].
  4. Chimney Rust: Mortar crumbles = leaks.
