What should I look for regarding roof condition?

Are you standing on a roof time bomb? Here’s what most buyers miss—and what to check now.

Why roof condition matters

A bad roof destroys value fast. Water damage, mold, and rot spread behind walls. Insurance problems follow. A smart buyer treats the roof like the foundation: inspect first, assume second.

11‑point roof inspection checklist (quick, direct)

• Age of roof: Ask for installation date. Asphalt shingles usually last 15–25 years. Clay, metal, and slate last longer.
• Shingle condition: Look for curling, cracking, missing shingles, or granule loss (bald spots).
• Flashing: Check metal flashing around chimneys, vents, valleys and skylights. Loose or corroded flashing leaks.
• Gutters and downspouts: Blocked or oddly stained gutters show poor water flow or past leaks.
• Roof valleys: These concentrate water. Missing shingles or bending here is major risk.
• Ridge and hips: Staples or broken caps are signs of wear or poor installation.
• Ventilation and soffits: Poor ventilation shortens shingle life and causes ice dams in cold climates.
• Interior signs: Water stains on ceilings, mold, sagging drywall or attic insulation that’s damp.
• Attic inspection: With a flashlight, check roof decking for dark streaks, soft spots, or daylight showing through.
• Structural sag: Any dip in roofline could be framing or decking failure.
• Recent repairs: Patch jobs can hide bigger problems. Ask for receipts and contractor info.

Red flags that deserve a hard stop

• Active leaks inside the home.
• Multiple patched areas across the roof.
• Mold or rot in attic framing or sheathing.
• Missing or rusted flashing around chimneys and vents.
• Major sagging or soft spots underfoot.

What to ask during the inspection

• How old is the roof and who installed it? Get permits if available.
• Any warranties? Are they transferable?
• Was the roof replaced or layered over old shingles?
• Can the inspector provide roof deck photos and moisture readings?

When to call a roofing pro

If you spot soft decking, persistent stains, corroded flashing, or widespread missing shingles, schedule a licensed roofer for a full diagnostic and written estimate. Small issues become big costs fast.

Simple math buyers should use

Repair estimate > 5% of home price? Negotiate. Replacement estimate > 10%? Walk if budget is tight.
