Roof Inspection Checklist: What Professionals Look For
Regular roof inspections are essential for preserving the integrity of your home or commercial building. Whether you’re maintaining a property, preparing for seasonal changes, or dealing with recent storm damage, a professional roof inspection ensures that potential problems are caught early before they lead to costly repairs. Here’s what certified roofing professionals typically look for during a standard roof inspection.
1. Exterior Roof Condition
Shingles and Roofing Material
One of the first things inspectors evaluate is the state of the roofing material. For asphalt shingles, they check for:
- Curling or buckling edges
- Cracked or missing shingles
- Loss of granules (which can signal aging or hail damage)
For other materials like metal, slate, or tile, professionals look for corrosion, chips, or dislodged panels.
Flashing and Seals
Flashing, which protects vulnerable roof areas (like chimneys, vents, and skylights), must be intact and watertight. Improper or deteriorating flashing is a common cause of leaks.
Gutters and Drainage
Gutters are checked for blockages, sagging, or improper slope. Accumulated granules or debris in the gutters may indicate deteriorating shingles.
Signs of Moss, Algae, or Mold
Vegetative growth not only looks unsightly but also traps moisture that can accelerate roof degradation. Inspectors look for dark streaks, green patches, or fuzzy growth.
2. Structural Issues
Inspectors will assess:
- Sagging: This could indicate underlying structural damage or trapped moisture.
- Damaged rafters or decking: These are more easily spotted from the attic or under-roof structure.
- Proper roof ventilation: Poor attic ventilation can lead to moisture buildup and reduced lifespan of your roofing system.
3. Interior Inspection
A complete roof inspection includes checking the interior of your home:
- Ceilings and walls: Water stains or bubbling paint may be signs of roof leaks.
- Attic: Inspectors check for light penetration (which may indicate holes), mold growth, or wet insulation.
4. Signs of Water Damage
Professionals carefully search for any indicators of current or previous water infiltration. This may include:
- Rusted nails
- Warped sheathing
- Damp insulation
- Mold or mildew odors
5. Condition of Roof Penetrations
Vents, skylights, satellite mounts, and plumbing stacks that pass through your roof are vulnerable points. A professional will:
- Check the seals around penetrations
- Look for signs of wear or cracking
- Ensure flashing is correctly installed
6. Chimney Inspection
If you have a chimney, the chimney structure is inspected for:
- Loose bricks or mortar
- Cracked crown
- Flashing issues
- Signs of leaking at the base
Why a Professional Inspection Matters
Even minor issues can become major problems if not addressed quickly. A qualified roofing expert can spot subtle warning signs you might miss during a DIY check. Plus, many warranties require periodic professional inspections to remain valid.
