Durability of Slate Roofing

Slate, a natural stone product, is renowned for its longevity and aesthetic appeal. It thrives in continental climates because of its thermal resistance and durability, handling both hot summers and cold winters with ease. However, the weight and cost of slate can be prohibitive for some homeowners.

Suitability of Clay Tiles

Clay tiles, popular in tropical and dry climates, offer resistance to decay, mold, and fire. They have a high thermal mass, which helps regulate indoor temperatures. Their primary drawbacks are their weight and fragility, requiring a strong support structure and careful installation.

Challenges of Wood Roofing

Wood roofing, often in the form of shingles or shakes, provides a rustic aesthetic and good insulation, making it a possible choice for polar climates. However, it requires high maintenance and is susceptible to fire unless treated with a fire retardant.

Impact of Climate on Each Roofing Material

Effects of Temperature on Asphalt Shingles
