Signs the roof is near the end
- Granules collecting in gutters and bare patches on shingle faces
- Curling, cupping or cracked shingles across whole slopes
- Repeated leaks in different places, not one repaired spot
- Daylight visible in the attic, or dark stained decking
- Sagging lines along the ridge or between rafters
One leak is a repair question. Leaks in several places are usually a roof-age question.
The sequence of a proper tear-off
Protect
Landscaping, siding, windows and attic contents are covered before work starts.
Strip
Old shingles, underlayment and failed flashing come off down to bare deck.
Inspect the deck
Soft or delaminated sheathing is replaced, and the cost basis for that is agreed in writing beforehand.
Build the barrier
Ice and water protection goes at eaves and valleys, then underlayment across the field.
Flash and vent
New metal at every wall, chimney and penetration, with ventilation balanced.
Cover
Shingles or metal panels go on, followed by ridge details.
Clean and verify
Magnetic sweep for nails, final walkthrough and photos of the finished work.

Common questions
Layering hides the deck from inspection and adds weight. A full tear-off lets us see and fix what is underneath.
Yes. A cold, dry attic reduces ice damming and moisture, and a hot one shortens shingle life.
