When a roof needs a full tear-off
Shingle Roofs · 6 min read ·
A roof needs a full tear-off when the deck under the shingles can no longer be trusted, or when you want the next roof built from a clean start. Stripping to bare wood is the only way to see and fix what the old shingles were hiding.
What tear-off actually means
A tear-off removes every layer of old roofing, shingles and old felt alike, until the crew is standing on the wooden deck. From there the roof gets rebuilt in order: deck repairs if needed, new underlayment, new shingles, then caps and vents.
The alternative on some houses is going over the top, which is what we do with metal over shingles. A tear-off generally costs more in labor and disposal, so the question is always whether the deck under you justifies it.
Signs it is time to strip it
Nobody can promise what is under a roof until it comes off, but certain clues point toward a tear-off in most cases.
One clue alone may not settle it. Two or three together usually do, and the site visit is where we put them side by side.
The brick ranch, stripped
On the brick ranch re-roof in September 2026, we took the old roof all the way down to the deck. The hero photo shows that stage: bare wood decking on a one-story ranch, the brick chimney partway down the slope, and a slot already cut along the peak so the house could vent through a ridge vent once the new roof was on.
A roll-off sat in the front yard to take the old shingles as they came off. With the deck exposed, Titanium underlayment went down, then gray architectural shingles from the eaves up both slopes.
Tear-off is when hidden damage shows itself
In June 2026 we stripped an attached section on another house and found the framing along the roof edge rotted through. From the ground, damage like that is often hard to spot. Once the old roofing was off, there was no question.
We cut out the bad wood, rebuilt the framing and patched in new sheathing before any underlayment went down. That job has its own post: what rotted roof framing looks like.
It does not have to be the whole house
Sometimes only part of a roof needs to come off. On the Onyx Black re-roof in October 2026, we stripped the shingled lower sections of a farmhouse down to the deck and left the red metal roof on the main section alone.
Scope like that gets decided on the roof, section by section, not from a satellite photo.
Tear-off before metal, too
The same logic applies if you want a metal roof. When the deck is solid, metal can go right over the shingles, as our metal-over-shingles explainer shows. When it is not, the Design Studio has a tear-off-first option so we know to plan for it.
For shingles, start with the quote form. We come out, walk the roof, and tell you plainly whether we think it needs to come off.
Questions
How do I know if my roof needs a full tear-off?
A roof usually needs a full tear-off when the deck feels soft underfoot, the roofline sags, the edges show rot, leaks keep coming back, or there are already two or more layers of shingles. Schaub and Sons checks those signs in person and tells the homeowner whether stripping to the deck makes sense before pricing a re-roof.
What happens during a roof tear-off?
During a roof tear-off, the crew removes all of the old shingles and felt down to the wooden roof deck, hauls the debris away, repairs any damaged sheathing or framing, and then installs new underlayment, new shingles, and the ridge vent and caps. Schaub and Sons used a roll-off dumpster for debris on its September 2026 brick ranch tear-off.
Can you tear off only part of a roof?
Yes, part of a roof can be torn off and replaced while other sections stay. In October 2026 Schaub and Sons stripped only the shingled lower sections of a farmhouse down to the deck and re-roofed them in Owens Corning Duration Onyx Black shingles, leaving the existing red metal roof on the main section in place.
Why does a tear-off sometimes find rotted wood?
A tear-off finds rotted wood because old shingles hide the deck and framing from view. Slow leaks at edges, chimneys and valleys can soak the wood for a long time before anything shows inside. On a June 2026 job, Schaub and Sons removed the old roofing and found the framing along one edge rotted through, then rebuilt it before re-roofing.
