Seal. Protect. Extend Your Roof’s Life.
If you have an asphalt shingle roof, you know how important it is to keep it protected from the elements. Over time, sunlight, rain, wind, and freezing temperatures take their toll—loosening granules, drying out the asphalt, and shortening the life of your roof. Kool Seal Clear is designed to stop that damage in its tracks.
The gritty surface on shingles isn’t just for looks—it’s vital for UV protection. Kool Seal Clear bonds to those granules, holding them in place so they don’t wash away.
Creates a transparent, water-tight shield that stops moisture from seeping under shingles, which helps prevent rot, mold, and costly leaks.
Asphalt shingles naturally degrade under constant sunlight. This coating blocks harmful UV rays, slowing the drying and cracking process.
Because it’s clear, your roof keeps its original color and style—just with a subtle, freshened appearance.
The coating expands and contracts with temperature changes, so it won’t crack or peel like rigid paints.
Painting shingles with ordinary paint can trap moisture, cause granule loss, void warranties, and even violate building codes. Kool Seal Clear is different—it’s a breathable, specialized acrylic roof coating made to work with shingles, not against them.
Applied correctly, Kool Seal Clear can add years to your roof’s life. Many homeowners see a noticeable reduction in maintenance and storm-related wear. And with a 5-year limited warranty, it’s protection you can count on.
Whether your shingles are brand new or a few years old, sealing them now can save you thousands in premature replacement costs. Kool Seal Clear keeps your roof looking great, functioning better, and lasting longer—all without changing its appearance.
