Asphalt shingle roofing
Architectural and three-tab, repaired or replaced.
When you're paying for the third repair on the same slope, you're not fixing a roof anymore — you're renting time.
The honest threshold is not an age. It's when shingles are brittle across the whole roof, granules are gone, the deck is soft in more than one place, or repairs keep appearing somewhere new. At that point the repairs cost more than they buy.
Tear-off matters here. A lot of Ohio Valley roofs carry a second layer over the original, which hides deck rot, prevents proper flashing work, and adds weight to framing that was sized for one layer. Going over a third time is how a deck gets condemned.
What's underneath does the work: deck repair where it's soft, ice-and-water shield at eaves and valleys, synthetic underlayment across the field, then flashings and edge metal. The shingles are the part you see and the least important layer in the system.

Primary coverage is Pittsburgh and Allegheny County, with regular dispatch into the close South Hills, North Hills, and Washington County towns.
Most single-family tear-offs run one to three days depending on layers, pitch, access and weather. Steep hillside lots and slate take longer.
You can shingle over one layer in some cases, and it's usually a false economy. It hides deck rot, prevents proper flashing, and shortens the life of what goes on top.
Yes, with caveats. Shingles need warmth to seal, so cold installs need hand-sealing and a weather window. Some jobs are better tarped and scheduled for spring.
