One of the more expensive parts to your home is your roof. Replacing a roof can become very costly, even forcing you to take out an additional mortgage, so it definitely makes sense to take good care of it. Your roof is exposed to the sun throughout the day, which can make it brittle. It can also get pounded by rain and hail, or carry the heavy weight of a thick layer of snow. While you might not be able to alleviate these problems, you do have the ability to lower the impact they have. When it rains, the water needs to drain off the roof well, or you will have problems caused by the standing water. For this, your drains and gutters need to flow well. If you are expecting heavy rain, take the time to check them.
You should clear off any collections of leaves or other debris where water can soak in. In the wintertime, it might be necessary to clear some snow off of the roof to make sure it doesn’t get too heavy.
