Roofs need to be cleaned regularly to keep off all the debris that collects there and makes homes for critters, insects, and mold. But, remember that hundreds of people in the USA–people who get paid to work on roofs–die each year from falling off the roof. It’s dangerous work for a number of reasons.
If you don’t know what you are doing and you step on a weak spot in the roof, off you go. Or, if you don’t place the ladder properly on the ground, you might end up on the hard ground. And then there’s the weather–unexpected rain or a sudden wind that can throw you off balance. Finally, for those of you who fear heights or have an inclination to misjudge where to step, you are in trouble. Let the professionals do the jobs safely.
You need to take good care of your roof and preserve its life for as long as possible. Not only does this save you the expense of a new roof, but taking care of it improves the aesthetic appearance of your house. And last of all, a roof in good shape helps keep you cool in the summer and warm in the winter.
