Full roof replacements do not need to be performed too often. The average shingle roof should last up to 20 years. However, that lifespan can be cut short by factors such as installation errors and weather damage. The best way to figure out if you need to completely replace your roof, or if a repair job will do, is to talk to a roofing contractor.
Extent** of the Damage**
The extent of the damage is a major factor to consider. If the damage is limited to one or two small areas, then you should be able to get by with repairs instead of a replacement. It may even be possible for your roofing contractor to match the appearance of the new shingles to the old ones.
Presence of Sagging
If your roof appears to be sagging, don’t wait to get it repaired—call a roofing contractor right away. Sagging is an indicator of major water damage. The contractor will need to replace the entire roof.
Possibility** of Ridge Asymmetry**
In some cases, it may be possible to tear off and replace all of the shingles on one side of the roof. Homeowners who are interested in saving money may prefer this option compared to tearing off and replacing the entire roof. However, your contractor will have to consider how many layers of shingles your roof already has. (You or the previous homeowner may have decided to reroof over the old shingles instead of tearing them off.)
If there are already a couple of layers on, they’ll have to be torn off before new shingles can be applied. And if you’re only replacing one side of the roof, then there will be a noticeable height difference between the new and old sections, given that the old sections will still have multiple layers of shingles underneath. In this case, consider tearing off and replacing the entire roof.
