Not All "Roof Inspections" Are the Same Thing

This matters more than people realize: a roof inspection during a home purchase and a dedicated roofing inspection aren't the same service, even though both get called "roof inspections." InterNACHI's official Standards of Practice for general home inspectors explicitly state the inspector isn't required to walk on any roof area that appears, in their judgment, unsafe — meaning a standard home inspection's roof assessment is often a ground-level or eave-level visual check, not a full walk of the surface. Under that standard, a general inspector is required to check roof-covering materials, gutters, downspouts, and visible penetrations like vents and flashing — a real and useful check, just a more limited one than a roofing specialist would perform. That's not a flaw in home inspections; it's simply a different scope of work than a specialized roofing inspection provides.

What a Dedicated Roofing Inspection Covers

Shingle or membrane condition, up close. Curling, cracking, granule loss, or blistering — the kind of detail covered in our UV aging article — is far easier to catch walking the surface than viewing it from the ground.

Flashing and seams at every penetration. Chimneys, vents, skylights, and valleys are where thermal cycling stress concentrates (see our companion article), and these points need close inspection, not a distant visual scan.

Gutters, downspouts, and drainage paths. Checked for attachment, clogging, and granule buildup — the early warning signs covered in our monsoon and maintenance articles.

Attic access. Checking for daylight through the decking, moisture staining, and ventilation adequacy from underneath — signs that often aren't visible from the roof surface itself.

General structural signs. Sagging, soft spots, or anything suggesting the decking itself has been compromised, not just the surface material.

Why the Distinction Between Inspection Types Matters

If a home purchase inspection reported "no issues" with the roof, that's genuinely useful information, but it reflects the scope of a general inspection, not necessarily a close roofing-specific assessment. A roof that passed a ground-level visual check during a home purchase can still have flashing or attic issues that only show up on a closer inspection. This isn't about one type of inspection being wrong — it's about knowing which one you had.

What This Means Practically for Homeowners

  • If you're buying a home, know what level of roof inspection you're getting — ask directly whether the inspector will access the roof itself or assess from ground level.
  • A dedicated roofing inspection is worth scheduling separately if your only roof assessment so far has been part of a general home inspection.
  • Ask for a written report with photos, not just a verbal summary — this matters for your own records and for any future insurance or warranty questions.
  • Timing matters too — see our maintenance checklist article for when a roofing-specific inspection is most useful in New Mexico's climate calendar, rather than scheduling one at a random point in the year.
