Why ground-only inspection is good enough
Insurance adjusters do most of their inspection from the ground. So do experienced roofers on initial estimates. Climbing on the roof creates risk (every year, ER visits from homeowner ladder falls outnumber actual roof emergencies) and isn't necessary to identify the failures that matter — granule loss, missing shingles, sagging, flashing damage, and gutter problems are all visible from the curb with a pair of binoculars.
What you need
Don't overcomplicate this. The full kit:
- Binoculars (any pair, even hunting/birding ones)
- Phone with camera (you're documenting findings)
- Notepad or notes app
- Optional: roof inspection app or printable checklist
Step 1: The 4-corner walk
Walk to each corner of your house and look up at the roof from each angle. You're looking for the overall shape — does the ridge line stay straight? Are slopes consistent or do they sag in the middle? Are eaves level with each other? Curbside view from a neighbor's yard or across the street is even better — distance helps you see the overall shape. Photograph each angle.
Step 2: Inspect each slope through binoculars
Pick a slope. Through binoculars, scan it left-to-right, top-to-bottom. Note:
- Color uniformity — patches of darker shingles indicate replacement areas (recent repair) or moisture damage (problem)
- Granule loss — bald or speckled patches mean shingle is at end-of-life
- Curling, cupping, clawing — edges turning up means UV damage
- Missing or lifted shingles — wind damage; mark the row and column
- Moss or algae streaks — biological growth, mostly cosmetic but accelerates decay
- Daylight gaps where shingles should overlap — installation defect or wind lift
Step 3: Inspect penetrations
Penetrations are where 80% of leaks start. Walk around the house and identify each one — chimneys, plumbing vent pipes, attic vents, skylights, satellite dish mounts. For each, look at the flashing (the metal trim around the base):
- Is it intact? Rusted or missing flashing = needs repair
- Is the rubber boot around plumbing vents cracked or torn? They fail every 15-25 years
- Are there obvious gaps where caulk has shrunk?
- On chimneys: is the step flashing layered into the shingles or just slapped on top with caulk? Caulk-only flashing fails fast
Step 4: Check the gutters
Walk along each gutter run from the ground. Look for sagging sections (gutter pulling away from the fascia), gaps at corners and joints, missing downspout extensions. Then look UNDER the downspout discharge — if you see a pile of granules or shingle pieces accumulating, that's tells you the roof is shedding material faster than it should.
Step 5: Fascia, soffit, and wall stains
Look at the fascia (the trim board where the roof meets the wall) and the soffit (underside of the eaves). Water stains, soft/rotted wood, or visible mold here indicate water has been getting past the gutters or under the shingles for a while. Check for stains running down exterior walls below windows or roof valleys — these mean a leak path that's been active.
Step 6: Attic check (optional but valuable)
If you have attic access, take 5 minutes up there with a flashlight. Look up at the underside of the deck. You're checking for: water stains on the wood (active leaks), rusty nail tips (condensation issue or active leak), daylight visible (holes), or dark mold patches. Touch insulation in suspect spots — wet insulation indicates an active leak even if the deck above looks dry.
When to call a pro
Get a professional inspection if you find any of these:
- Sagging or wavy roof line — structural concern
- Daylight visible through the deck
- Active interior leak or fresh ceiling stain
- Multiple missing shingles across more than one slope
- Sustained moss/algae over 30%+ of any slope
- You can't safely see your roof from the ground (heavy tree cover, multi-story angles)
