It has been raining heavily in California in recent years. In 2021, California received about 33.9 trillion gallons of water through rain, which was more than it had received in 2020. If you’re living in California, you should know that your roof can get damaged from rainwater buildup.
Moss is a collection of tiny flowerless plants that survive in damp and shady places. It is a non-vascular plant, which means it does not have any roots and hence, absorbs water through its pores. As it does not have the roots to grip onto surfaces, it spreads horizontally instead of growing upwards. Roofs are the likeliest places for moss growth as they are usually damp. Thin, green layers of moss may grow between shingles and then spread rapidly on rooftops.
