How to judge roofing work

A roof is the one system that protects every other part of a building, which is why the way a contractor inspects matters more than the brochure. A thorough look covers flashing, penetrations, valleys and decking — not just the field of shingles — because that is where water actually finds its way in.

Roof lifespan depends more on installation quality and attic ventilation than on the material alone. Poor ventilation cooks shingles from underneath, and incorrect nailing patterns void many manufacturer warranties. The useful questions to ask any roofer are about process and sequence, not only price.

Typical lifespan ranges by roofing material (industry averages; actual life depends on climate, ventilation and installation quality)
Material	Typical lifespan	Notes
Asphalt shingle	15–30 years	Most common; ventilation strongly affects service life
Metal	40–70 years	Standing seam generally outlasts exposed-fastener panels
Clay or concrete tile	50–100 years	Underlayment usually needs renewal sooner than the tile
Slate	75–150 years	Weight requires adequate framing capacity
Single-ply membrane (flat)	20–30 years	Seams and terminations are the usual failure points

More detail: questions they hear most.
