What’s Hiding Under Your Roof?
Why 20-Year-Old Roofs Should Be Replaced Sooner Than You Think
Most homeowners never really know what’s happening beneath their shingles. From the street, your roof might look fine—but after about 20 years, serious problems can be hiding underneath.
At Team Roofing NW, we’ve seen it all. Once we remove the old shingles, we often find rotting plywood, damaged trusses, and poor ventilation
that’s been quietly causing mold growth inside the attic. These issues usually can’t be seen from the outside, which is why a roof that was installed in 2005 or earlier
is due for a closer look.
Why Roofs Installed Before 2005 Are at Risk
Roofing standards and materials have come a long way in the last two decades.
Older installations often lacked:
- Proper underlayment and ventilation systems
- Ice- and water-shield protection around valleys and eaves
- Modern nailing patterns and high-quality fasteners
- Synthetic moisture barriers that prevent rot
Because of that, many older roofs are now failing from the inside out—even if the shingles still look okay from the outside.
What We’re Finding Beneath Old Roofs
When our crews remove aging shingles, we’re finding:
- Rotting plywood that can no longer hold fasteners
- Water-stained or weakened trusses that jeopardize the roof’s structure
- Mold growth from trapped moisture due to poor ventilation
These are detrimental issues that go unnoticed until the tear-off phase. Without access to the attic, most homeowners would never see them coming.
Case Study: Roof Replacement in Everson, WA
One recent project in Everson, Washington, shows exactly why replacing an older roof matters.
The home was being sold, and we were hired to replace the roof as part of the sale contingency—so the original homeowners wouldn’t have to pay out of pocket.
When we began the tear-off, we discovered that the plywood was completely black and rotting. Because this section of the home had no attic space, there was no way to identify the issue earlier. Once the plywood was removed, we found that the trusses were also deteriorating
and had to be sistered in to restore the structural integrity.
After making the necessary structural repairs, we installed brand-new plywood sheets, ensuring a solid, safe foundation
for the new roofing system.
Why Acting Sooner Saves You Thousands
Replacing your roof before visible issues appear can actually save money in the long run:
- Hidden leaks can slowly cause thousands in damage before you notice them.
- Roofing material costs increase every year, meaning a roof replaced this year may cost significantly less than waiting one or two years.
- Unexpected structural repairs discovered later add to your total cost.
In short: replacing an aging roof early prevents surprise expenses and protects your home’s long-term value.
Our Promise: Transparency and Trust
Whenever we uncover hidden damage, we immediately:
- Show homeowners photos of all findings
- Explain what needs to be fixed and why
- Adjust pricing only for materials and labor that were truly unexpected
We believe in fixing the problem the right way—not putting a band-aid on a major wound. Our goal is always to leave you with a roof built to last, not just look good on the surface.

Here in the Pacific Northwest, roofs deal with constant moisture, shade, and organic debris — the perfect environment for unwanted growth. But many homeowners don’t realize there’s a big difference between moss and algae on a roof. They may look similar from the street, but the impact they have on your home (and your warranty) is completely different. Understanding the difference helps you protect your home and make the best decision when it’s time for roof cleaning, maintenance, or replacement.
