Best Roof Sealants for Shingle Roofs
The best roof sealants for asphalt shingle roofs perform well under the circumstances they were made for. For example, the best roof sealant to protect against UV rays won’t necessarily be the same sealant that works best against moisture.
The best roof sealants include:
Best Overall: The best overall roof sealant for asphalt shingle roofs is silicone. This man-made, solvent-based roof sealant features the most protection with the longest life. Strong against water, moisture, and sun damage, silicone is also typically the most expensive.
Best Budget: The best budget roof sealant is rubber. Though rubber may have a shorter life span than silicone, it still provides strong protection against moisture and UV rays.
Best for Sun: The best roof sealant to protect your asphalt shingle roof against the sun is acrylic. Featuring both water- and solvent-based options, acrylic is best for places with regular sunshine that see little rain. It’s not made for being moisture-resistant, so acrylic has a longer life in dryer climates.
Best for Water: The best roof sealant for water and moisture is polyurethane. Opposite of acrylic, it’s best for areas prone to rain and snow since it’s highly moisture-resistant. However, this solvent-based formula doesn’t rate as high for protection against UV rays.
Easiest to Use: The roof sealant that’s the easiest to use is tape. Using a straightforward approach, the moisture-resistant tape is thin with adhesive backing. Tape is placed over the leak to seal the damaged area.
