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.

The time needed to install a new roof depends on several variables, such as the size and number of stories in your home, the type of roof being installed (asphalt shingles versus metal roofs), and any special features that may require additional work. On average, most asphalt shingle roofs can be completed in one day if there is only one story. If your house has two stories or a complex roof line with many angles, it might take two days or more depending on roof size. Metal roofs typically take longer to install than asphalt shingles due to their specialized materials and installation requirements; for example, it may involve cutting custom pieces for flashings and valleys.

In addition to the actual installation process itself – which usually takes 1-2 days – other related tasks are involved when replacing a roof like debris removal from attic spaces, re-decking/adding new plywood underlayment over an old existing layer of plywood sheathing, installing ice & water shield around eaves as well as along ridges located below base flashing locations. These are all factors that need to be taken into consideration when estimating how long it will take for you to have a completely installed new roof over your house.
