Pros
- Easy to apply with sprayer, roller, or brush and dries clear quickly
- Stops leaks on older roofs and improves shingle flexibility and color
- Reduces residue and granule shedding even in heavy rain
- Environmentally friendly water-based formula
- Enhances wind, impact, and UV resistance
Cons
- Ineffective on severely damaged or unsalvageable shingles needing replacement
- Requires application above 45°F on dry surfaces with no rain for 1-2 hours
- Thin consistency may lead to overspraying if not back-rolled
Nationwide Coatings Shingle Sealer is a 100% acrylic clear waterproofing product designed for asphalt shingle roofs showing signs of age like granule loss, drying, or minor leaks. It suits homeowners wanting to extend their roof's life affordably without a full replacement, especially on garages, homes, or mobile homes with moderately worn shingles.
The sealant stands out for its ability to penetrate shingles, re-glue granules, and leave a flexible breathable film that blocks moisture and UV damage while allowing vapor escape at 24 perms. Real-world performance shines in reviews, with users reporting stopped leaks, restored color and flexibility, less residue in rain, and dramatically reduced granule loss. Testing confirms just 0.2% granule loss after rigorous scrubbing versus over 5% untreated.
Application is straightforward with a backpack sprayer, roller, or brush, covering 250-350 sq ft per gallon per coat for up to 700 sq ft total. The water-based formula cleans up easily with soap and water, dries to touch in one hour, and provides a beautiful gloss without altering shingle colors. Build quality reflects decades of proven global use with excellent gloss retention and resistance to wind, impact, and salt spray.
Drawbacks include limitations on very old or heavily stained roofs, where cleaning first and assessing viability is key, plus strict weather requirements like no rain post-application and temps over 45°F. Overspraying can occur due to its thin nature, so back-rolling is advised.
Overall, Shingle Sealer delivers reliable rejuvenation and protection, making it a smart choice for maintaining shingle roofs cost-effectively. Highly recommended for proactive roof care based on consistent positive feedback.

Apply to clean, dry shingle roofs above 45°F with low humidity; avoid rain for 1-2 hours post-application. Use two thin coats at 250-350 sq ft per gallon via sprayer (back-roll), roller, or brush. For heavy granule loss, pair with PERMAGLUE or consider PERMAKOTE coating. Test small area first on porous shingles.
Best for roofs with life left; not a fix for structural damage or black stains on failing shingles. Expect improved appearance, leak prevention, and longevity on moderately aged surfaces.
