The Original SHINGLE SEALER™ is the only clear waterproofing roof sealant built exclusively for asphalt and fiberglass shingles. Penetrates and rejuvenates the shingle surface, re-glues loose granules, and waterproofing in one application. The 100% acrylic, crystal clear formula delivers excellent weather resistance and durability against wind lift, impact, and salt spray. Water-based for easy soap and water cleanup. In testing, uncoated shingles lost over 5% of granules in 1,000 scrub cycles; Shingle Sealer reduced that loss to just 0.2%.

SHINGLE SEALER™ is an Acrylic Sealer for Protecting, Rejuvenating & Waterproofing Shingle & Granulated Roof Surfaces.
SHINGLE SEALER™ leaves a clear light gloss film with a permeability rating of 24 perms, so your shingles keep breathing after sealing. It allows the water vapor to escape while blocking the larger water molecule. The water-based formula carries VOC content less than 50 gr/ltr, qualifies as a Green Safe low-VOC coating, and is manufactured in the USA.


Rejuvenates discolored, tired and weathered shingles, restoring their natural color with a rich clear gloss finish. Real-world results show an 18-year-old treated roof outperforming a 5-year-old untreated addition on the same home. Prevents dirt and debris from sticking, keeping your roof cleaner longer.


SHINGLE SEALER™ extends the functional life of aging but serviceable asphalt and fiberglass shingle roofs, helping property owners avoid the cost of full roof replacement. Available 7-year limited warranty from Nationwide Coatings, a USA manufacturer since 1964.

Superior Mold, Mildew and Fungi Resistance. Eliminates harmful water intrusion by the sheeting off of water on the roof, thus reducing the environment for mold, mildew and fungi formation and cleansing the roof of dirt and pollution.
fortified with a high solids resin blend of advanced ingredients like polymers and acrylics, penetrates your roofing shingles, while simultaneously leaving behind a breathable film that enhances their durability. SHINGLE SEALER™ is your solution, as it re-glues and secures loose shingle granules, waterproofing and safeguarding your shingle roof from the elements.



Pure high solids acrylic formulation ensures a crystal-clear finish that not only enhances the natural beauty of shingles but also provides a waterproofing barrier for long-lasting weather protection. Its penetrating technology and transparent nature allows the original colors of shingles to shine through while offering protection against moisture, UV rays, and environmental factors for years to come.

Apply by backpack, pump-up, or industrial airless sprayer, or brush and roller for smaller areas. Thin water-based formula will not clog your sprayer tip as it penetrates deep into the shingles and leaves a breathable topical film behind to protect the shingle roof and lock down shingle roof granules. Two coats at 250 to 350 sq ft per gallon per coat (average 300 sq ft per gallon). Clean up with soap and water.


Two coats recommended for best results. Average 300 sq ft per gallon (250-350 sq ft depending on surface porosity). 750 sq ft = 5 gal; 1,500 sq ft = 10 gal; 3,000 sq ft = 20 gal. For roofs with some granule loss, use PERMAGLUE before applying. Unfortunately there is no magic sauce for a bad roof but Shingle Sealer works great on most roofs. Not effective on shingles with no remaining serviceable life.

“We had a persistent leak in our shingle roof due to, as it turned out, improperly installed shingles. We could never find an exact spot where the leak was originating, but it was damaging our ceiling and creating a lot of anxiety. Found Nationwide in an internet search. Appreciated that their products are made in the US, had a contractor friend look them over, and decided to make a call. I could not be more pleased with the customer service. Brion was courteous, knowledgeable, and genuinely interested in what was best for our project, encouraging me to purchase a less expensive product because in his opinion it was what we actually needed. And he was right, the product was exactly what we needed. Our roof is 14 years old, shingles in reasonable condition, but clearly in need of a sealer. The sealer went on easily; we did two coats. Since then we’ve had heavy rains in multiple occasions, and the roof no longer leaks. It’s completely dry underneath, much to our relief. ”
