Painting asphalt shingle roofs has been a subject of debate and confusion among homeowners and contractors alike. While the idea of rejuvenating the appearance of a weathered roof through a fresh coat of paint may seem appealing, it is important to understand why it is virtually impossible to achieve satisfactory and long-lasting results when attempting to paint asphalt shingle roofs.
One of the primary reasons why painting asphalt shingle roofs is not recommended is the surface texture of the shingles themselves. The mineral granules on the shingles create a rough, uneven surface, which is not conducive to paint adherence. Consequently, paint applied to the shingles tends to peel, crack, or flake off over time due to poor adhesion, exposure to weather elements, and the natural expansion and contraction of the roof.
Furthermore, painting asphalt shingle roofs can have detrimental effects on their functionality. The granules on the shingles serve as a protective layer, shielding the asphalt from the sun's rays and preventing premature deterioration. When these granules are covered with paint, the shingles become more susceptible to UV damage, leading to faster deterioration and a shortened lifespan.
If you have to make your roof look new and fresh, consider replacing your entire asphalt shingle roof instead of painting over it. It's easy to install if you hire a reliable roofing contractor and have a long-term roof protection for your property by making it look new.

Painting shingles is absolutely possible, and there are both benefits and drawbacks to shingle painting. Painting roof shingles in a bright, reflective color, like white, can give any home a new, attractive appearance and also reflect the heat from the sun, helping to keep cooling costs lower in the summer months. However, you need to have the right asphalt shingle paint and ensure that it doesn’t trap moisture inside the roof layers, which could lead to mold, mildew, and wood rot.
You can paint a roof, but keep in mind that the material of the roof matters. You can paint asphalt shingles, metal sheeting, concrete, slate, and clay tiles, but terra-cotta roof tiles have a glaze that prevents paint from binding to the surface properly, even with specialized roof shingle paint.
With the realization that you can paint shingles, it’s also important to consider the potential benefits and drawbacks of painting a roof. Several great reasons for painting roof shingles include an instant update to the appearance, extension of the roof’s lifespan, and the low cost of this DIY project.

Instant Visual Update
Often the most attractive reason for painting the roof is that you can quickly make a home’s appearance more appealing. While asphalt shingles can look good when paired with certain exteriors, they don’t necessarily match the aesthetic of every house. With that in mind, painting your shingles is a great way to instantly update the look of your home.
Extended Roof Lifespan
As long as you choose the correct shingle paint, which should be specifically marketed as a high-quality acrylic latex paint intended for painting asphalt shingles, then a layer or two of paint can help improve UV radiation resistance. It also provides a protective layer to help reduce wear over time.
Low Cost
Reshingling the roof is the usual way to change its appearance, but a much more affordable method for updating a home’s look is to simply paint the shingles. Purchasing the paint, renting a paint sprayer, and painting the roof yourself are significantly less expensive than the cost of reshingling the roof. (Read more here)
