Have you ever considered replacing your roof? If so, you were probably worried about the cost when looking at different options. With the average roof costing around $20,000 to replace, taking good care of the roof you have, so as to extend its lifespan, is only common sense.
One of the things that can do the most damage to your roof, no matter what material it is made from, is water. You should do all you can to prevent water from pooling on top of your roof. This means keeping it free from debris and leaf piles. You should also ensure that your gutters are flowing well, since water could back up from a clogged gutter and do damage to your roof. If you are not comfortable working on your roof, you might need to hire someone to take care of this for you.
Cutting back tree branches that extend over your roof can also help in keeping it from getting damaged.
