However, it's important to keep in mind that wood shake roofs are best suited for dry climates, as they don't fare well in wet conditions. Moisture, mold, and insects can have a negative impact on their longevity. Additionally, you'll need to budget for fire retardant treatments, as they are required for safety. On average, the cost for a wood shake roof is around $20,000, and its lifespan typically spans 25 years. So, if you're looking for a roofing option that combines style, natural beauty, and eco-friendliness, consider a wood-shake roof for your home.
