The Farmhouse With A 5-Layer Roof Sandwich

The Ultimate Example Of Roofers Kicking The Can Down The Road.

Our SmartSeries showcases how we take a more intelligent approach to roof replacement than your average roofing company in Greater Seattle. We don’t just address the symptoms—we fix all underlying problems to maximize your roof’s lifespan and performance.


If you want picture proof of how lazy roofing companies can be, this is the case study for you.

Sam owned a historical farm in Bellevue. He’d recently built a new house on the land, but he left the old house up.

Sam called us for two reasons. First, he wanted a new metal roof installed on his pole barn. Second, the old farmhouse’s roof was leaking, so he needed to replace it.

Replacing the pole barn’s roof was relatively straightforward. Replacing the farmhouse’s roof? Let’s just say that project had “layers.”


The Roof Sandwich

We first started the re-roofing job on Sam’s old farmhouse. While we were removing the old shingles, we were blown away by what we found: Not one… not two… not three… not four… but FIVE LAYERS of old shingles.

Our “Fiver-Layer Surprise.”

During the initial inspection, we believed there were two layers of shingles. How did we not see the other three? Because the prior roofer cut the layers back at the edges to hide them. Sneaky!

Here are a few photos of the removal process:

Why, exactly, were there so many layers? Because all the previous roofers just kept installing new shingles over the existing ones. None of the roofers bothered to tear off the old shingles.

In other words, roofers kept kicking the can down the road.

Removing all of these shingles was tough. The “sandwich” was so thick that the previous roofer used framing nails instead of roofing nails for the top layer of shingles. To put that in perspective, framing nails are about three times longer than roofing nails.

In the process of removing the shingles, we broke two shovels!

What we found underneath didn’t surprise us. There was a ton of rot and water damage. This, plus the sheer weight of all the shingles, actually caused Sam’s ceiling to sag.

This was a BIG problem, and it left Sam with two options: reframe the roof or completely tear out the ceiling. Since tearing out the ceiling would be a very costly and messy process, Sam chose to reframe the roof.

So we got to work…

After fixing all the “under the hood” problems, we were finally able to start installing the new shingles. For this project, we used Owens Corning Duration shingles because of the good balance between durability and cost.

The roof sandwich made things take a little longer than expected, but we finally finished Sam’s new farmhouse roof.

But our work wasn’t done.


One Roof Down… One To Go

Remember, we were also re-roofing Sam’s pole barn. Thankfully, that was much more straightforward. No roof sandwiches. No saggy ceilings.

We initially planned to complete Sam’s project in two days. That was before we found the roof sandwich. When all was said and done, we worked on Sam’s job for an entire week.

But let’s face it—sometimes it takes a little longer to make sure things are 100% RIGHT. There was NO WAY we were going to continue kicking the can down the road like the previous roofers. That nonsense ended with us.
