Why We Always Strip a Roof Down to the Decking

Here's something a lot of homeowners don't know until it's too late - layering new shingles over old ones is one of the biggest shortcuts in the roofing industry. Some contractors push it because it's faster and cheaper on their end. But what it does is lock in every problem that already exists under those shingles, and now you can't see any of it.

When we do a roof replacement, we strip everything off. Every layer, down to the bare wood decking. That's the only way to actually know what you're working with. Soft spots, rot, water-damaged OSB - none of that shows up until the old material is gone. We've found decking issues on jobs that looked completely fine from the ground.

A roof is only as strong as what it's nailed to. If the decking is compromised and you install new shingles on top of it, you're spending real money on a roof that's already sitting on a weak foundation. It doesn't matter how good the shingles are. The whole system fails faster than it should.

What we do instead is give the new roof a clean, solid surface to start from. Any bad decking gets addressed before a single new shingle goes down. That's how a replacement is supposed to work - not a cover-up, but a fresh start built to last.

If a roofer is quoting you a job and they're not talking about a full tear-off, that's worth asking about. The extra step isn't just a preference - it's the difference between a roof that holds up and one that hides problems until they get expensive.
