There are many features of your home that serve a practical purpose, and many of them are located on the exterior of your home, as that is where a lot of damage can occur, as a result of exposure. Of these, the roof could be considered the most important, when it comes to keeping the rest of your home dry and safe from the elements. Because of all this exposure, though, you need to be especially mindful of your roof, in terms of maintenance. There are many ways in which a roof can become damaged, and it is in your best interest to find out as soon as possible, so you can do something about it. That is why it is considered prudent to get a roofing inspection, from good roofing contractors, once per year.
The main reason it is a good idea to get a roofing inspection, once a year, is the fact that weather can have a very detrimental effect, on your roof, even if there has not been a terribly severe storm. If you live in a temperate zone, with harsh winters and harsh summers, it is even more likely that your roofing will undergo some sort of damage. As a matter of fact, one of the reasons the extremes, with regards to the seasons, are so damaging is the fact that the winter weather exacerbates the damage that your roof may undergo, during summer storms. For example, if your roof is hit by a few hailstorms, over the course of the summer, there is a good chance that some portion of your roofing, could be weakened or damaged. The likelihood of this is substantially greater, though, if your roof was not installed properly to begin with, but damage can occur, regardless.
The time of the year that is best for an inspection is the end of the summer or the beginning of the fall, since that is the window of time, between the destructive hail storms of summer and the harsh winter weather that comes with living in a temperate region. By timing the inspection, in this way, you will have plenty of time to complete any repairs that may be necessary, but you will still have avoided the hail season, so there will be a low chance of more damage occurring, before winter. If damage is discovered, there are a couple of possible courses of action. The first is to have them repair the damaged portion of your roof, and the second is to have them replace all of your roofing. While the former seems more logical, in many cases, the latter is cheaper and more practical. For one thing, your roofing is not likely to last too long, regardless, so it is often in your best interest to replace your roofing, anyway. Furthermore, in some cases, it is actually less costly to just re-roof, rather than to try to repair the damaged portion. It is important to have trustworthy roofers, so you can know that they are giving you sound advice, on the matter, though.
