how long do asphalt shingles really last anyway?
Been thinking about this lately...say you buy a house and the seller says the roof shingles are "good for 25 years," but um, what if they start looking rough after like 15? Would you trust the original estimate or start budgeting early?

Honestly, those "25-year" estimates are pretty optimistic. I've seen shingles start curling and losing granules around the 12-15 year mark, especially if they're exposed to harsh weather or direct sun. Manufacturers base their lifespan claims on ideal conditions, which most roofs rarely experience. I'd definitely start budgeting early - better safe than sorry. Maybe get a roofer to inspect every few years once you hit that halfway point, just to stay ahead of any surprises.
A 25-year label isn’t necessarily a prediction that every roof will need replacement at year 25.
- Curling or granule loss around 12–15 years is a reason for a close inspection, but not by itself proof that the roof has failed.
- Installation quality, attic ventilation, roof slope, weather exposure, and maintenance can matter as much as calendar age.
- Budgeting early makes sense, but replacement should be based on the roof’s actual condition rather than age alone.
