When deciding whether to repair or replace a roof, there are several factors to consider. The age and condition of the existing roof will play a major role in the decision making process. Generally speaking, if your roof is more than 20 years old, it is usually better to replace rather than repair it as repairs may only be a temporary fix that won’t last long-term. A good rule of thumb is that any major damage such as holes caused by weathering or bucks from hail can significantly reduce the life expectancy of your existing roof system and therefore should be replaced.

This applies also when you have multiple layers of shingles on your home as having two roofs on top of each other increases moisture retention and reduces ventilation which can lead to accelerated aging and further damage down the road. Additionally, when assessing whether repair vs replacement makes more financial sense, it’s important to factor in costs associated with energy efficiency as well; newer roofs typically offer superior insulation capability resulting in lower heating and cooling bills over time which adds value to your property along with providing better overall climate control for those living inside the building itself.

All these factors must be taken into account when choosing between repair or replacement for an existing roof system but generally speaking if it’s older than 20 years then replacement is often times preferred due its longer lasting performance characteristics versus repairs that might not hold up against future weather conditions.
