Complete Guide to DIY Roof Inspection

Regular roof inspections can help you catch small problems before they turn into major (and expensive) repairs. Here's how to conduct your own roof inspection safely and effectively.

When to Inspect Your Roof

Perform a roof inspection:

• Twice a year (spring and fall)
• After severe weather events
• If you notice interior water damage
• Before listing your home for sale

Safety Considerations

Important: Roof inspections can be dangerous. Never inspect a roof during wet or icy conditions, and always use proper safety equipment.

Consider hiring a professional if:

• Your roof is steeply pitched
• You're uncomfortable with heights
• You lack proper safety equipment

What You'll Need

• Binoculars (for ground-level inspection)
• Ladder (if accessing roof)
• Camera or smartphone
• Notebook
• Flashlight (for attic inspection)

Exterior Inspection

1. Check from the Ground

Start by examining your roof from the ground using binoculars. Look for:

• Missing, cracked, or curling shingles
• Damaged flashing around chimneys and vents
• Sagging areas
• Excessive granule loss (dark spots on asphalt shingles)

2. Inspect Gutters and Downspouts

Clean gutters tell you a lot about your roof's condition:

• Excessive shingle granules in gutters indicate aging shingles
• Check for proper drainage and no overflow
• Look for rust, holes, or sagging

3. Examine Flashing

Flashing seals the areas where your roof meets walls, chimneys, or vents. Check for:

• Rust or corrosion
• Gaps or lifted edges
• Cracked caulk or sealant

Interior Inspection

Attic Inspection

Your attic can reveal problems not visible from outside:

1. Water Stains: Dark spots on rafters or decking indicate leaks
2. Daylight: If you can see daylight through the roof boards, you have gaps
3. Mold or Mildew: Indicates moisture problems
4. Proper Ventilation: Ensure soffit and ridge vents are clear

Ceiling Inspection

Check interior ceilings for:

• Water stains or discoloration
• Peeling paint
• Sagging areas

Common Problems to Look For

Missing or Damaged Shingles

High winds and age can cause shingles to crack, curl, or blow off entirely. These need immediate replacement to prevent water infiltration.

Flashing Damage

Damaged flashing is a leading cause of roof leaks. Check around chimneys, skylights, and vents.

Moss and Algae Growth

While not always harmful, excessive growth can trap moisture and damage shingles over time.

Sagging Roof Deck

A sagging roof indicates structural problems and requires immediate professional attention.

Maintenance Tips

• Keep gutters clean
• Trim overhanging branches
• Remove debris regularly
• Address small problems quickly

When to Call a Professional

Contact a roofing professional if you find:

• Significant water damage
• Structural issues or sagging
• Extensive shingle damage
• Problems with flashing
• Any issue you're unsure about

Documentation

Keep a record of your inspections:

• Take dated photos
• Note any concerns
• Track repairs and maintenance
• Save receipts and warranties

Regular roof inspections are a smart investment in your home's longevity. By catching problems early, you can extend your roof's lifespan and avoid costly emergency repairs.

Remember, while DIY inspections are valuable, professional roofers have the experience and equipment to spot problems you might miss. Consider having a professional inspection every 3-5 years, or more frequently if your roof is older.
