Your roof is constantly exposed to the elements, and because of this, it could have its lifespan shortened. Between rain, snow, sunshine and wind, there is a lot of wear, and considering the cost of replacing your roof, it is in your best interest to counteract all those things.
So, what can you do since you can’t change the weather where you live? One thing that you can do is to keep water from staying on your roof for an extended time. Your gutters and downspouts are essential when it comes to keeping your roof clear of water. If they are blocked, then water will not drain off as easily. Clearing off leaves and branches from your roof will also help to keep water from collecting.
Constant exposure to sunlight can also cause damage to the surface of the roof, making it brittle and easily damaged. The weight of snow could pose another problem. If too much snow is left on the roof, it could collapse.
