Three Layers of Roofing in Westland, Michigan: Why It Happens and Why It Matters
When most homeowners think about replacing their roof, they picture a simple tear-off of old shingles, some cleanup, and then a fresh new roofing system going on. But in many neighborhoods across Michigan—especially in places like Westland—we often find something very different once we start tearing into the roof structure.
That “something different” is exactly what we uncovered on a recent project: three full layers of roofing stacked on top of each other.
And while it might sound shocking, it’s actually more common than you’d think.
Why Do Homes End Up With Multiple Layers?
Years ago, many roofers and homeowners treated roofing like a stackable upgrade. Instead of tearing the old layer off, they simply installed a new one right over the top. It seemed like a quicker, easier, and cheaper option at the time. But roofing technology, building codes, and long-term durability requirements have changed a lot since then.
Here’s why multiple layers are a problem:
-
Excess weight: Shingles are heavy. Three layers add thousands of extra pounds to a home’s structure. That weight pushes down on rafters, decking, and framing.
-
Trapped moisture: Layers of old shingles can hide leaks that have been soaking the wood underneath for years.
-
No visibility of underlying issues: Soft spots, rot, mold, and gaps stay hidden until a full tear-off.
-
Shorter lifespan for the new roof: New shingles don’t lay or seal correctly when installed over old ones.
This is exactly why today’s building codes in Michigan require a full tear-off when there are already two layers present.
What We Found in Westland
On this Westland, MI job, our crew began the tear-off expecting the usual one or two layers. But as the first layer came off, we found another. And under that—another.
Three full layers, each aging, curling, cracking, and hiding the problems below.
This is the moment where experience matters. A triple-layer tear-off isn’t just more work—it requires careful handling, clean removal, and making sure the home stays protected throughout the process. Once everything was stripped down to the wood deck, we finally got a clear look at the condition of the structure. That revealed areas that needed new sheathing and repairs before the new roof could go on safely.
Without a proper tear-off, none of those issues would have been visible.
Why a Proper Tear-Off Protects Your Home
Tearing off all layers isn’t just the “right” way to do it—it’s the safest. Here’s what the homeowner gained by doing it the right way:
-
A roof deck that is inspected and repaired instead of covered up
-
Cleaner installation that helps shingles seal properly
-
A longer-lasting roofing system
-
Better energy efficiency and ventilation
-
Peace of mind knowing the home meets building code
A roof is more than shingles—it’s a full system made to protect your biggest investment. That protection starts with what’s underneath.
What Homeowners in Westland Should Know
If you live in Westland or the surrounding area, here’s a simple tip: you never really know how many layers are on your roof until a professional takes a look. Older neighborhoods often have multiple generations of roofing stacked up. Even if everything “looks fine” from the ground, the truth might be hiding under the surface.
Our goal isn’t just to replace roofs. It’s to make sure the house beneath them stays strong, safe, and dry for years to come.
