Many homeowners don’t think about their roofs unless they notice an obvious problem, such as a major leak or a caved in section of roof. However, some roof problems can be repaired, while others indicate that the roof is overdue for replacement.

If you’re trying to decide whether to replace your roof rather than repair it, there are several factors you ought to consider.

The roof’s age

The older the roof is, the more likely it is to need to be replaced rather than repaired. As a general rule of thumb, if your roof is more than 15 years old, it makes more sense to replace it than repair it. If any portion of the roof appears to be rotting or shingles appear curled or loose, you might want to consider replacing the roof. Recruit the help of professionals like ACI Roofing to assist you in determining whether you should repair or replace your roof.

Keep in mind that you may be able to replace only part of the roof while keeping the rest of the original roof if damage is limited to only one section of roof.

Roof shingles are designed to last for 15 to 20 years; however, exposure to high winds can cause shingles to become loose or break off even if the roof is younger than this.

If you have several missing shingles in the roof, you probably need to re-do your shingles. As shingles break, the shingles around them start to loosen so that more shingles continually come off. You need to replace shingles–or the entire roof if most of the shingles are missing or broken–as soon as possible once they start loosening.

Shingle installation problems


Errors in installing the shingles on your roof can cause you roof problems. If your shingles are curling up at the edges, it means one of three things. The shingles could simply be old or in need of replacement, but more often you have a problem with either the ventilation in your roof or the roof itself. You can try adding more ventilation to your roof to see if that solved the problem.

If the problem isn’t in the ventilation system, however, it probably means the shingles were not installed properly. Depending on how many shingles are curling up, you may need to replace the entire roof.

If you have asphalt shingles on your roof, they may be deteriorating, which requires you to replace the shingles. You can tell when these shingles have deteriorated beyond repair by examining them. If the shingles have a pitted appearance, meaning you can see black spots in some areas of the shingles, then they need to be replaced.

If all of your shingles are deteriorating, it’s time to consider getting a new roof altogether. You may want to consider getting other roofing materials rather than asphalt if you replace the roof because asphalt tends to deteriorate over time.

The question of whether to replace the roof depends on its age and how widespread any problem you’re having with it is. Sometimes you can get away with just replacing a few shingles, but if you’re having problems all over the roof, it makes more sense to get a new roof, especially if your roof has lasted several decades already.
