How to Spot Roof Damage: Complete DIY Inspection Guide

Your roof silently protects your home 24/7, but damage often goes unnoticed until it causes serious problems. Regular inspections can save thousands in repair costs by catching issues early. This comprehensive guide teaches homeowners how to identify roof damage safely from the ground and attic—no ladder required for most checks.

Why Regular Roof Inspections Matter

The Cost of Neglect

Small Issues Become Major Problems:

• Minor leak: $300-$500 repair
• Water damage from ignored leak: $5,000-$15,000
• Roof replacement due to neglect: $8,000-$25,000+

Hidden Damage:

• Mold and mildew growth
• Structural rot
• Insulation damage
• Ceiling and wall damage
• Decreased home value

Recommended Inspection Schedule

Routine Inspections:

• Twice yearly (spring and fall)
• After major storms
• Before and after winter
• When buying/selling a home
• Every 5 years by professional

Safety First: Before You Inspect

Never Climb on Your Roof If:

• You're uncomfortable with heights
• Roof pitch is steep (greater than 6/12)
• Roof is wet, icy, or snow-covered
• You lack proper safety equipment
• You're alone
• Roof appears unstable or damaged

Safe Inspection Methods

From the Ground:

• Use binoculars for distance viewing
• Walk around entire perimeter
• Look from multiple angles
• Check during different lighting conditions

From the Attic:

• Use flashlight in daylight
• Look for light penetration
• Check for water stains
• Inspect insulation and decking

Professional When Needed:

• Steep or high roofs
• After severe storms
• Suspected structural issues
• Before buying/selling home

Ground-Level Inspection: What to Look For

1. Missing or Damaged Shingles

Asphalt Shingles:

Missing Shingles:

• Gaps in roofing pattern
• Exposed underlayment (usually black)
• Increased wind noise during storms

Curling Shingles:

• Edges turning upward
• Corners lifting away
• Indicates age or poor installation

Cracking:

• Visible splits in shingles
• Brittle, dry appearance
• Common in older roofs (15+ years)

Blistering:

• Raised bubbles on surface
• Dark spots or discoloration
• Result of trapped moisture

Granule Loss:

• Shiny, bare spots on shingles
• Granules in gutters and downspouts
• Color fading or discoloration
• Indicates aging or damage

Action: A few damaged shingles = repair; widespread damage = replacement consideration

2. Sagging or Uneven Roof Lines

Signs of Structural Issues:

Visible Sagging:

• Dips or waves in roof line
• Uneven ridge
• Drooping between rafters

What It Means:

• Weakened roof decking
• Insufficient support structures
• Water damage to framing
• Overloaded roof (too many layers)
• Age and deterioration

Danger Level: High - indicates serious structural problems

Action: Call professional immediately; may be safety hazard

3. Damaged or Missing Flashing

Critical Leak Points:

Chimney Flashing:

• Gaps between chimney and roof
• Rust or corrosion
• Loose or missing pieces
• Cracked caulking

Vent Pipe Flashing:

• Cracks in rubber boots
• Rust around base
• Loose or lifted metal
• Improper sealing

Valley Flashing:

• Rust or corrosion
• Lifted or loose edges
• Visible fasteners
• Improper installation

Step Flashing (walls/dormers):

• Gaps between siding and flashing
• Rust or deterioration
• Bent or damaged pieces

Action: Flashing repairs are critical; schedule repair promptly

4. Gutter and Downspout Issues

Warning Signs:

Granule Accumulation:

• Black sand-like material in gutters
• Heavy granule loss indicates aging
• Normal aging: light granules
• Excessive loss: damage or defect

Sagging Gutters:

• Pulling away from fascia
• Water pooling in gutters
• Indicates excess weight or damage

Peeling Paint:

• On fascia boards
• Behind gutters
• Indicates water overflow or leaks

Staining:

• Vertical lines on siding
• Water marks below gutters
• Shows inadequate drainage

Action: Clean gutters seasonally; repair separation promptly

5. Moss, Algae, and Vegetation

Growth Types:

Black Streaks (Algae):

• Gloeocapsa magma bacteria
• Cosmetic issue primarily
• More common in humid climates
• Can trap moisture if severe

Green Moss:

• Thrives in shade and moisture
• Lifts shingle edges
• Retains moisture (accelerates damage)
• Common on north-facing slopes

Lichen:

• Combination fungus and algae
• Similar issues to moss
• More aggressive than algae

Trees/Plants:

• Growing in gutters
• Roots penetrating roof
• Indicates neglected maintenance

Action: Remove vegetation; improve sunlight exposure; consider algae-resistant shingles

6. Chimney Damage

Inspect:

Mortar Joints:

• Crumbling or missing mortar
• Gaps between bricks
• White staining (efflorescence)

Chimney Crown:

• Cracks in concrete cap
• Missing pieces
• Water penetration

Flashing:

• As mentioned above
• Most common chimney leak point

Action: Chimney repairs prevent major water damage; address promptly

7. Signs of Animals or Pests

Evidence:

Birds:

• Nesting materials
• Feathers
• Droppings

Squirrels/Rodents:

• Chewed shingles or wood
• Holes in soffits
• Scratching noises

Bats:

• Droppings (guano)
• Entry holes
• Odors

Insects:

• Carpenter ants (wood damage)
• Wasps/hornets nests
• Termite damage

Action: Remove pests; repair entry points; inspect for damage

Attic Inspection: Interior Warning Signs

1. Light Penetration

What to Look For:

Visible Daylight:

• Through roof boards
• Around vents or chimneys
• At eaves or ridge
• Any pinprick holes

Meaning:

• Holes in roof deck
• Missing or damaged shingles
• Gap in underlayment
• Potential leak points

Best Time: Bright sunny day

Action: Mark locations; inspect from outside; schedule repairs

2. Water Stains and Leaks

Stain Types:

Active Leaks:

• Dripping water
• Wet insulation
• Fresh water stains
• Visible moisture

Old Water Damage:

• Brown or yellow stains
• Dark rings on wood
• Dried water marks
• Musty odors

Location Clues:

• Near chimneys (flashing)
• Around vents (boot cracks)
• In valleys (ice dams, poor flashing)
• At eaves (ice dams)

Important: Water often travels; leak location may be far from stain

Action: Active leaks = emergency; old stains = investigate and monitor

3. Mold and Mildew

Signs:

Visual:

• Black or green spots
• Fuzzy white growth
• Discolored surfaces

Smell:

• Musty, earthy odor
• Damp smell
• Stronger in hot weather

Texture:

Health Concerns:

• Respiratory issues
• Allergies
• Structural damage

Action: Identify source; fix leak; professional mold remediation if extensive

4. Damaged or Wet Insulation

Check:

Compressed Insulation:

• Matted, flattened appearance
• Reduced effectiveness
• Result of water damage or age

Wet Insulation:

• Dark discoloration
• Must be replaced (ineffective when wet)

Missing Insulation:

• Gaps in coverage
• Moved by animals
• Inadequate installation

Ice Dams Connection:

• Insufficient insulation
• Poor attic ventilation
• Heat loss causes ice dams

Action: Replace damaged insulation; improve ventilation; seal air leaks

5. Sagging or Damaged Roof Decking

Warning Signs:

Sagging Between Rafters:

• Visible dips or waves
• Deflection when pushed
• Water damage or age

Rot or Decay:

• Soft, spongy wood
