The Hidden Risk of Roof Layering & Why Brown Roofing Always Recommends a Full Tear-Off

When a roof needs replacing, it can be tempting to save time and money by installing new shingles right over the old ones. It’s a common shortcut, and some contractors still offer it. But the truth is, roofing over an existing layer can cause more harm than good.

What Is Roof Layering?
Layering, also known as "roofing over," is when a new set of shingles is nailed directly on top of old ones. While this method technically gives your home a new outer surface, it doesn’t address what might be lurking underneath.

Why It’s Risky
The biggest danger of roof layering is what it hides. With the original shingles still in place, there’s no way to inspect the condition of the wood decking beneath. If there’s rot, moisture damage, or weak spots, you won’t know... until it’s too late.

Shingles are also heavy. Two layers add extra weight that your roof structure may not have been designed to support long-term. Over time, that added weight can lead to sagging or even structural issues.

Full Tear-Off = Full Peace of Mind
At Brown Roofing, we never do shingle overlays. Every project starts with a full tear-off, no exceptions. That way, our crews can carefully inspect the decking and replace any soft or damaged wood before installing your new roofing system.

Once the decking is solid and secure, we tape the seams, add ice and water shield, and install a synthetic underlayment. Only then do we install your new shingles, giving you a roof that’s solid from the ground up.

Why It Matters
A roof is more than just shingles. It's a system that depends on strong layers working together. Cutting corners by layering might save a little money upfront, but it risks major issues down the line.

That’s why Brown Roofing never layers over old shingles. We do it the right way, every time, because we believe your home deserves nothing less.
