DIY Roof Inspection Tips for Homeowners

Keeping your roof in good condition is key to protecting your home from the elements and avoiding costly repairs. While hiring a professional for an annual inspection is essential, a simple DIY roof inspection can help you spot early signs of trouble. Regular inspections allow you to address minor issues before they turn into major ones. Here are some easy tips from Lightning Exteriors to guide you through a safe, effective DIY roof inspection.

1. Start with an Interior Check

Before heading outside, check for signs of roof issues from inside your home. These can provide clues to potential leaks or structural problems that may need attention.

• Look for Water Stains: Check ceilings and walls for water stains or discoloration, which could indicate a leak.

• Check for Mold or Mildew: Musty smells or visible mold may mean moisture is entering your home from a compromised roof.

• Inspect the Attic: If accessible, head to your attic with a flashlight. Look for any sunlight peeking through, which could indicate holes, as well as damp insulation or wooden beams.

Addressing water intrusion early can prevent mold growth and further damage to your home’s structure.

2. Inspect the Roof from the Ground

For a safe inspection, start by examining your roof from the ground. Using binoculars can give you a closer look without needing to climb a ladder.

• Look for Missing or Damaged Shingles: Broken, curling, or missing shingles are a common sign of roof damage. Make a note of any areas that appear worn or bare.

• Check for Granule Loss: If you see bald spots or notice granules in your gutters, it may indicate that your shingles are aging and losing their protective coating.

• Inspect Flashing and Roof Edges: Flashing around chimneys, vents, and skylights can become loose or damaged over time. Make sure it’s intact and firmly in place.

• Examine Gutters and Downspouts: Look for debris or granules collecting in your gutters, as these can signal that your shingles are deteriorating. Clear any blockages to ensure proper drainage.

Regularly cleaning gutters and checking for shingle granules will help you catch potential problems early on.

3. Climb Carefully if Needed

If you’re comfortable with heights and have the proper safety equipment, you can use a ladder to get a closer look. However, take extreme caution, as roof inspections can be dangerous without proper safety measures.

• Use a Sturdy Ladder: Set up your ladder on a stable, level surface and ensure it’s in good working condition.

• Avoid Walking on the Roof: Roofs are designed to protect, not to be walked on. Walking on your roof can damage shingles or tiles, especially if they’re already compromised.

• Focus on Key Areas: Check the flashing, shingles, and any areas around vents or chimneys where leaks are more likely to occur.

If you’re uncomfortable or uncertain about climbing, it’s best to leave the close-up inspection to a professional roofer.

4. Watch for Signs of Sagging or Structural Issues

A sagging roof can indicate a more serious problem with the roof’s underlying structure. This can happen due to excessive weight, water damage, or aging materials.

• Check for Uneven Roof Lines: Stand back and look at your roof from a distance to see if any sections appear to be sagging or drooping.

• Inspect Support Beams: In your attic, look at the support beams for signs of warping, cracks, or moisture.

If you notice any sagging, contact a professional immediately. Structural issues can compromise the integrity of your entire roof.

5. Inspect Seals Around Skylights, Vents, and Chimneys

The areas around skylights, vents, and chimneys are prone to leaks due to their exposed nature. Water can enter if the seals around these elements are damaged.

• Look for Cracks or Gaps: Inspect around these openings for any visible cracks, gaps, or missing sealant.

• Check for Rust or Corrosion: Metal flashing or seals can rust over time, weakening their effectiveness.

Regularly checking these seals helps prevent water from seeping into your home.

6. Examine Your Roof’s Surface for Algae, Moss, or Lichen Growth

Algae, moss, or lichen growth on your roof may look harmless, but they can trap moisture against your roofing materials, leading to premature wear.

• Look for Green or Black Streaks: Algae often appear as black streaks, while moss appears as a green, fuzzy growth.

• Gently Clean as Needed: If you spot moss, you can gently clean it using a mild solution of water and bleach. However, avoid scrubbing, as this can damage shingles. A professional can help with more intensive cleaning.

Moss and algae thrive in shaded, moist areas, so keeping your roof clear of debris and tree branches can reduce their growth.

7. Check Your Gutters and Downspouts

Proper drainage is essential for roof health. Clogged or damaged gutters can cause water to back up and pool, which may lead to roof leaks and water damage.

• Clear Out Debris: Make sure your gutters and downspouts are free from leaves, twigs, and other debris. Clean them regularly to prevent blockages.

• Inspect for Damage: Look for any signs of rust, cracks, or sagging sections. Damaged gutters may not direct water away from your roof and foundation as effectively.

Keeping your gutters in top shape helps prevent water damage and extends the life of your roof.

8. Look for Evidence of Animal Damage

Squirrels, raccoons, birds, and other critters can cause damage by nesting on or near your roof.

• Check for Signs of Nesting: Look around chimneys, vents, and gutters for nesting materials or droppings.

• Inspect for Chewing or Holes: Animals can chew through shingles or flashing, creating potential entry points for water.

To prevent animal damage, trim tree branches near your roof and consider installing protective measures around vulnerable areas.

When to Call in the Professionals
