The Best Roofing Shingles for a Damp Climate

Asphalt

• Organic asphalt shingles do not hold up well in humid climates where they typically warp, but asphalt shingles with algaecides applied work well. Algaecides consist of an algae-resistant coating sprayed or painted on each shingle that helps keep moss and algae from weakening the wood. In you live in a cooler, humid climate, choose dark asphalt shingles with algaecide to help the roof absorb heat during the winter. If you live in a tropical climate that gets hot during the summer, light-colored asphalt shingles help keep your house cool. To maintain value in your home while protecting the roof, consider architectural asphalt shingles that resemble cedar, slate or tile. As long as the shingles are coated with algaecide, architectural shingles add beauty and appeal to your home while keeping your roof in top condition.

Fiberglass

• A shingle made from fiberglass and asphalt makes an optimal roofing material in humid climates, especially in the south. Each shingle consists of hard asphalt topped with fiberglass. This union gives your roof high tolerance of both heat and humidity. Fiberglass and asphalt shingles come in a variety of weights with the heaviest offering the most roof longevity. The low cost of the shingles makes them an even more attractive material, especially since they come in a variety of colors and patterns.

Wood

• Most wood shingles come from cedar, a natural roofing material used for several centuries. A natural oil in cedar shingles helps repel water, making them ideal for a woodsy look in climates with lots of rain or humidity. The wood’s natural substance helps stop mold and mildew from rotting the shingle and causing leaks in your roof. Cedar shingles also help keep insects from chewing holes in your roof.

Slate

• Roofing options in damp climates where moss causes problems include slate shingles. These natural stone shingles provide a porous surface that supports moss growth. The shingles also offer strength and durability although their cost is higher than asphalt shingles. Slate shingles work best in wet areas in northern climates, especially on houses built along steep slopes. You may still need to control moss growth with annual cleaning and applications of a moss inhibitor.
