Best RV Roof Sealant – What To Look For


It’s every RV owner’s worst nightmare: a leak. A leak in your
roof can mean water damage, mold, and untold amounts spent in repairs and
ongoing maintenance if it’s not addressed properly. Fortunately, experienced RV
owners also know that there’s one thing they can rely on: quality sealant. The
challenge? Finding the best RV roof sealant for your unique needs. Here are a
few tips to help you find the right products.

How Does The Sealant

A sealant might be affordable, easy to dispense, and match
your materials—but if it doesn’t cure well, then it’s not going to be worth the
purchase. The first thing you should look for in determining the best RV roof
sealant for your RV is in the kind of
cure you can expect.

  • Curing in
    the presence of water
    . Moisture isn’t just bad when it comes to RV leaks—it
    can also get in the way of an effective sealant cure. A sealant that can cure
    in the presence of water will show resilience to moisture and give you more
    options when it comes to application.
  • Avoiding
    damage to the RV
    . A waterproof cure is great—but what if it damages the
    underlying material of the RV itself? Then the point is moot. Look for
    acid-free cures that won’t corrode the materials of your roof. When in doubt,
    read the label. If a sealant is high quality, it will likely avoid problems
    like corrosion and leaving black streaks on your RV.

A quality cure can make the difference between a seal that
will hold its structure for years—and a cure that might need its own seal
within a year or so.

Matching The Sealant To
The Material

The most important decision you make often isn’t in the
individual style of the sealant, but in picking up a sealant that’s
specifically designed for the material
you’re sealing.

For instance, Life
Seal® Silicone/Polyurethane Sealant
is formulated especially for
fiberglass, which is why it’s great to keep on hand for RVs with a lot of
fiberglass issues. But be sure to read the label of each sealant—for instance,
you’ll find that this version of Life Seal® also adheres to metal, glass, and

If you’re still in doubt, you might want to go for a
versatile sealant like Life
Seal® Silicone Rubber Sealant
. This sealant is great for a range of
materials—plastic, metal, wood, and fiberglass.
