Attic flashlight tour
Twice a year · typically February and August
Why it matters
Nobody goes in their attic, which is exactly why problems live there rent-free for years. Twice a year — once in winter, once in late summer — you stick your head up with a good flashlight and just look.
What skipping it costs
$800–$12,000
The attic is where roof leaks, bathroom-fan moisture, and critter damage all show up first — quietly. A wet patch of sheathing caught in February is a $300 flashing fix. The same patch found two years later is rotted decking, matted insulation, and a mold bill: $800 to $12,000 depending on how long it stewed.
Two ways to get it done
Do it yourself
You'll need: Bright flashlight or headlamp, Phone for photos, Dust mask if it's been years.
- Go up on a bright day, kill your flashlight for a minute, and look for daylight. Pinpricks at nails are normal; visible sky at vents' edges, flashing, or eaves is not.
- Lights on: scan the underside of the roof sheathing for dark staining, damp patches, or frost (winter). Follow any stain downhill to its source — it's usually a penetration, not the field.
- Check that soffit vents (at the eaves) aren't buried under insulation. You should see light or baffles at the eave line. Blocked soffits are the #1 attic ventilation problem and a free fix.
- Look for critter sign: droppings, chewed wiring insulation, tunneled insulation, nesting material. Listen for a few seconds too.
- Confirm bathroom fans and dryer ducts actually exit the roof or wall — not just dump into the attic. You'd be amazed.
- Photograph anything questionable with the date. Same spot, six months later, tells you if it's active or old news.
Walk only on the joists or laid boards — the drywall between them is not a floor, and stepping through a ceiling turns a free inspection into a $500 patch.
Hire it out
$150–$300National fair range — local labor moves this number.
A standalone attic inspection runs $150–$300, but here's the honest version: you rarely need to buy one. It rides along free with a decent roof inspection, an energy audit, or a pest inspection. If mobility or access hatches make DIY a no-go, fold it into one of those instead of paying for it alone.
What you're guarding against is the free-inspection-as-sales-funnel: insulation companies and mold franchises both use the attic as a closing room. Anything they find should come with photos, a moisture reading, and time to think. The attic isn't going anywhere.
Ask the tech
- Can you photograph anything you're flagging — wet spots, daylight, blocked vents?
- Is the ventilation actually blocked, or just imperfect? What's the moisture reading on the sheathing?
- If you're recommending more insulation, what's my current depth and what R-value am I at?
Red flags you're being upsold
- An 'attic inspection' that turns into a same-day insulation quote without a single photo of a problem. Insulation-topping is the easiest upsell in the trade because you'll never go up there to check.
- Radiant barrier or attic-fan pitches sold as energy miracles — the honest payback math on both is marginal in most climates.
- Mold panic. Light surface staining on sheathing is common; 'toxic mold remediation' quotes in the thousands need a second opinion, not a same-day signature.
Second opinion time: Any mold remediation quote over $1,000, or any insulation job over $3,000 — both are quoted sight-unseen constantly.
The call
DIY this one — it's twenty minutes with a flashlight and you're just looking, not touching. Hire it only if you physically can't get up there.
