If you’re a homeowner in Columbia, MD or nearby areas like Ellicott City, Laurel, or Clarksville, you may be wondering if your roof is ready for solar panels—or if it needs a little extra protection first.
One of the most overlooked upgrades? Installing ice & water shield under the area where your solar panels will be mounted.
Let’s break down what it is, why it matters in Maryland’s climate, and when it’s worth the investment.
What Is Ice & Water Shield?
Ice & water shield is a self-adhering roofing underlayment made of rubberized asphalt. Unlike regular synthetic underlayment, it creates a waterproof seal—especially around nails, fasteners, and roof penetrations. This makes it a powerful defense against water leaks, especially in high-risk areas like valleys, eaves, and anywhere something’s bolted through your shingles.
Why It Matters When Installing Solar Panels
Solar panel systems are usually mounted with brackets that go directly through your shingles and roof deck. Each of these mounting points is a potential entry for water if not properly sealed and protected.
When you install ice & water shield under the solar panel area, it adds an extra layer of protection that self-seals around those fasteners. Even if something shifts over time or a sealant fails, you still have a waterproof barrier in place.
Maryland Weather = A Real Risk for Roof Leaks
In Columbia and Howard County, we see it all—ice storms in winter, driving rain in spring, blazing sun in summer. That weather swings mean thermal expansion, roof movement, and freeze/thaw cycles, all of which can stress your roof over time. A basic underlayment isn’t always enough.
Adding solar panels introduces more components and more penetrations. Ice & water shield gives your roof a fighting chance to stay leak-free for the long haul.
When Should You Upgrade?
You don’t need to rip off your entire roof just to install ice & water shield—but if you’re already replacing your roof or planning to install solar, it’s the perfect time to add it.
