Description
A green, moss-covered roof may make you think you wandered into a fairy tale.. But, in the real world, moss is much less a fantasy than it is a nightmare. Left untreated, the clumpy greenery can cause virtually any roofing material to degradeââ¬âmost commonly wood and asphalt, but also metal, clay, and concreteââ¬âand thus drastically shorten its lifespan
