Repair or Replace? How to Read Your Roof's Actual Condition

You found a stain on the ceiling. Or a few shingles in the yard after a storm. Or your insurer wants pictures. The question is whether you're in repair territory or replacement.

The visible signs

Repair territory:

• Isolated wind damage to a few shingles

• A single flashing failure (chimney, pipe boot, valley)

• A nail pop or two visible on the roof

• A localized leak with no other symptoms

Replacement territory:

• Granule loss visible across the whole roof

• Curling, cupping, or clawing shingles broadly

• Multiple ceiling stains in different rooms

• Visible roof deck deflection from below

• A roof past two-thirds of its rated life with active leaks

The hidden signs

The deck (the wood underneath the shingles) tells you more than the shingles do. If a contractor pulls a shingle and finds delaminated OSB or punky plywood, that's a roof at the end of its life — repair is just buying time.

Age does matter

Asphalt shingles are rated 20-30 years; many last shorter because of ventilation issues. If your roof is over 18 years old and you've already repaired it twice, the next repair is rarely the right call.

What this means for you

Get two opinions before deciding. A contractor walking the roof with you (or providing drone photos) and explaining what they see — not just what they're selling — is the one to listen to.

What contractors should know

A documented inspection with photos of each issue and a clear repair-or-replace recommendation builds trust faster than any closing pitch.

Before you call anyone out

If you're not sure whether the work was done right, the cheapest first step isn't a contractor callback or a paid third-party inspection — it's a documented second opinion you can refer back to.

Supervisr's Roofing QA model follows industry standards and guidelines set forth by NRCA, ARMA, the IBHS FORTIFIED standard, OSHA (1926 Subpart M fall protection), and the major shingle, metal, and tile roofing manufacturers. It can analyze roof installation photos for shingle nail pattern, flashing detail at penetrations and sidewalls, underlayment and ice-and-water coverage, ventilation balance, and FORTIFIED-aligned construction details. Upload photos of shingle nail pattern, step and kickout flashing, ridge and soffit ventilation, valley construction, and chimney flashing detail, and you'll get a documented evaluation back in minutes with citations to the specific standards involved. It's the same checklist a careful inspector uses — applied to your photos, on your timeline.

For homeowners, that documentation is your conversation-starter with the contractor (or, if needed, your insurer or warranty carrier). For contractors, it's the third-party verification that closes the conversation cleanly.
