A professional roof inspection covers far more than the shingle surface. It looks at flashing, penetrations, valleys, the drip edge, ventilation, gutters and the attic underside for moisture and daylight. Homeowners can do useful monthly checks from the ground and from inside the attic, but walking a roof is where most homeowner injuries in this category happen.
Key points
- Most leaks start at a transition or penetration, not in the middle of a field of shingles.
- The attic tells you more than the roof surface does.
- Binoculars from the ground are a legitimate inspection tool.
What a professional inspection covers
- Flashing at chimneys, walls, skylights and vents
- Valleys, ridge and hip lines, and the drip edge
- Shingle condition: lifting, curling, granule loss and prior repairs
- Sealant and boot condition at every penetration
- Ventilation balance between intake and exhaust
- Gutters, downspouts and where water actually lands
- Attic underside for staining, damp insulation, mold and daylight
The monthly check you can safely do
Walk the perimeter with binoculars after any significant weather. Look for missing or displaced shingles, a shiny patch where granules washed off, a sagging line along the ridge or gutter, and debris piling in valleys.
Then go into the attic with a flashlight on a bright day. Turn the light off and look for daylight at the roof plane, then look for dark staining on the sheathing and any insulation that feels damp.
Found something you cannot identify?
Find roofing helpWhy walking your own roof is a poor trade
Roof surfaces are slick with dew, granules act like ball bearings underfoot, and a step in the wrong spot on aged decking can go through. Professionals carry fall protection and know how to move on a given material.
There is also a diagnostic reason. Untrained walking damages shingles and can create the leak you were looking for.
When to schedule one
- After hail, high wind or a storm that brought down branches
- Before buying or selling a home
- Before an insurance renewal if the roof is aging
- Once a year on any roof past the midpoint of its expected life
- Any time you see an interior stain, even a small one
