How Heat and Humidity Affect Asphalt Shingle Roofs in the Carolinas
Sep 14, 2026The climate in the Carolinas has many benefits, including plenty of sun all year long. However, the heat and humidity of sweltering summers can really do a number on your asphalt shingle roof. While asphalt shingles are designed to stand up to the elements, prolonged exposure to the sun’s rays in combination with persistent moisture in the air can degrade their performance and appearance over time.
If you are a homeowner in the Carolinas, understanding how local weather patterns may affect your roof is essential identifying problems early on, before they require more costly repairs. Below, our team at Merritt Roofing is providing a brief guide on asphalt shingle damage that can help you be proactive about keeping your Carolina roofing system in great shape from season to season.
How Prolonged Heat Affects Local Roofs
Skyrocketing summer temperatures can be a real challenge for asphalt shingle roofs, which absorb heat from direct sunlight. Over repeated heating and cooling cycles, shingles may begin to degrade, losing the flexibility that helps them provide such exceptional protection in the first place. If you notice any shingles starting to crack or curl, it’s possible that your roof is already suffering from the effects of heat damage.
One way to reduce the impact of heat on your roof is to ensure you choose asphalt shingles that are specifically designed for the type of weather conditions common to the Carolinas. For example, at Merritt Roofing, we install premium Owens Corning shingles that offer lasting performance in diverse weather conditions, including high heat and humidity.
High Humidity and Asphalt Shingles
Heat from the sun isn’t the only concern when it comes to protecting your roof against summer conditions. Consistently high levels of moisture in the air prevent your roofing system from ever having the chance to dry out completely. This in turn can contribute to the growth of algae, which often results in both ugly discoloration and structural issues. Furthermore, persistent humidity can lead to moisture intrusion, degrading your roofing system’s underlying components.
