How to Waterproof Asphalt Shingles

Asphalt shingles are a common roofing material due to their durability and affordability. However, over time, they can wear and tear, becoming more susceptible to water damage. If you want to keep your asphalt shingles in good condition and extend their lifespan, you should consider waterproofing them.

There are a few different ways to waterproof asphalt shingles:

1. Apply a sealant. This is the most common and affordable way to waterproof asphalt shingles. Sealants are available in various formulations, so choosing one specifically designed for asphalt shingles is essential. Applying the sealant is typically done with a brush or roller, and it can be done DIY.

2. Install a waterproof underlayment. This is another effective way to waterproof asphalt shingles. Waterproof underlayments are installed underneath the shingles and act as a barrier against moisture. They are available in various materials, including felt, rubberized asphalt, and synthetic polymers.

3. Use waterproof roofing nails. Standard roofing nails can rust over time, which can create leaks in the roof. To prevent this, you can use waterproof roofing nails, made of materials resistant to corrosion, such as stainless steel or aluminum.

4. Repair any damage. If you notice any damage to your asphalt shingles, you must repair them as soon as possible to prevent further water damage. Repairs can be done by replacing the damaged shingles or applying a sealant to the affected area.

By following these tips, you can help waterproof your asphalt shingles and extend their lifespan.
