Do you know if your house's roof is sound or not? When is the last time you had a professional inspect the roof on your house to look for any issues? If this is something that you've never done, it's probably time that you do so. While your roof might seem like it is in good condition right now, there are a number of reasons why your roof could be at or near the time that it needs to be repaired or replaced. Some of the biggest reasons why your roof may no longer be as good as you're thinking are:
Age: Most roofs will last for at least 3 decades, but this is just an average. There are many things that can cause a roof to prematurely age, such as various weather conditions or the use of inferior materials. If the previous homeowner used cheap and/or clearance shingles, they may not hold up as well as more expensive mid-range shingles would. An experienced roofing contractor will look for signs of aging that might not occur to the average homeowner and that you may be overlooking. Some of these signs, such as the loss of the protective covering of pebble-like aggregate on asphalt shingles, may not even be visible from the ground.
Exterior damage: If you have a large tree or two growing anywhere near your home, chances are good that storms have knocked branches off over the years and the wind has blown these branches onto the roof. They need not be large or heavy branches to damage the shingles; you might not even have noticed that it happened. A roofing contractor will look for scratches or holes caused by this type of damage. If there is any, he or she will let you know whether it's serious or if it can be put off for a while.
Interior damage: A lot of people are under the impression that as long as the outside of a roof looks sound then it is fine. This is simply not the case. Poor attic or crawlspace ventilation or animals getting into the space can result in damage that can be invisible at first. Rot can sometimes take hold with relative ease. If not discovered by a roofing contractor, this rot can spread and the roof may start to sag and be near collapse by the time it becomes obvious from the outside. Animals can gnaw on the roofing materials while building their nests, creating an increased chance of serious roof leaks.
