Replacing a roof is an expensive venture, but you also can't (and shouldn't) keep repairing your aging roof forever. Knowing when to throw in the towel and have your roof replaced is an important trick that will save you from possible roof collapse, water damage and other dangers of failed roofs. Here are four signs that mean it's time to stop repairing your aging roof:
The Roof Is Sagging
When an old roof starts to sag, it means that the damage it has experienced is more than cosmetic. In most cases, sagging starts when the roof support system (the structural framework) has been weakened and can no longer support the weight of the roof. Such damage can be caused by different issues such as water damage or the normal aging of the roofing materials. In most cases, the sagging of a roof can only be dealt with via roof replacement.
The Roof Experiences Frequent Failures
When you get to the point where you are calling for roof repairs every month or so, then there is probably major underlying issues that need to be solved. Maybe you have dealt with missing shingles, rotten trusses, water leaks and curling shingles within the last few months. Such frequent roofing issues tell you that it's time to stop patching up the roof and deal with the root of the problem once and for all by replacing the roof.
The Roof Needs a Major Repair
Many contractors will also advise you to replace your roof instead of undertaking a major repair that involves tearing off half or more part of the roof. For example, if you need to replace more than half of the shingles and tear off a huge chunk of the roof support, it might be a better idea to replace the entire roof. After all, even if you undertake the major repair, the remaining part of the roof may not last long before necessitating a repair too. In fact, in such cases, the cost of the major repair may not be too far removed from the cost of replacing your roof, which makes roof replacement even more attractive.
Patching up an old roof may extend its natural life, but it can't go on forever; there comes a time when it is best to opt for a total replacement. Listen to your roof contractor's advice to determine when to replace your roof so as not to waste further resources on piecemeal repairs.
