When roof damage occurs, you are left with a decision -- repair or replace. The following can help you make this decision.
It's important to know the average lifespan for your particular roof. The average lifespan is determined by the type of roofing material after taking into consideration outside factors. For example, an asphalt shingle roof may last upwards of 20 years, but if the roof is in an area that has frequent hail storms or if the last roof was installed over the old shingles, that lifespan may be as much of half the average lifespan. If a roof is approaching the end of its expected life, it makes more sense to replace it rather than repair it.
2. Hidden Damages
A roof may look like it only has minimal damage on the surface: for example, a single missing shingle. If that shingle has been missing for awhile, though, then extensive mold and rot may have affected the roof sheathing below. A roofer needs to fully inspect the roof before repairing the visible damage so that they can determine whether what is visible is just a small part of more extensive hidden damages. If you have a lot of hidden damage, it may be necessary to replace the roof.
A few blown off shingles may not seem like a big deal, but it may lead to a major appearance-based issue. Manufacturers are constantly changing and updating their product line. If your style or color of shingles has been discontinued, it may be impossible to find a close match. In this case, any repair may stand out like a sore thumb. You need to weigh whether or not you can live with a visible patch on the roof. If you are planning to sell anytime soon, it may be better to replace the roof.
4. Damage Severity
The severity of the damage may make it more financially feasible to replace the roof instead of paying for an extensive repair. If the roof was brand new, it may make sense to repair it. On the other hand, if the roof will be due for replacement in a few years, it may make more financial sense to just put on a new roof now.
5. Future Plans
Consider your future plans for the house. If you plan to stay in the house for a decade or more, it may make sense to simple replace the roof rather than pay out for many small repairs only to replace it anyway in a few years. On the other hand, if you plan to sell the house in the next year or two, it makes more sense to pay for a small repair now since you won't be the one paying for the eventual replacement.
