Roof Moss-It’s not a Rooftop Garden!

There are many quaint pictures of the English countryside of homes with moss covered roofs. The truth of the matter is, however, that moss can severely damage not only the roof, but an entire home! In many areas, it is a real problem. Some homes have only a small amount, at least at first. For some homes though, the roof moss is very obvious and can cover almost the entire roof. This is one reason that roof inspections and cleaning should be done at least twice a year. Spring and Autumn are perfect times to accomplish this task.
