If the shingles covering your residential roofing are nearing the end of their 20-year lifespan, start thinking about how you want to spruce up the top of your home. However, it can be difficult for homeowners to tell if they’d be better off with reroofing or a roof replacement. Here are both options in more detail to help you make the best choice for your property. 

What Is Reroofing?

Reroofing is the process of covering up old shingles with new ones. When homeowners opt for this service, they won’t have to tear up the old shingles — they just have to nail in new ones. While this choice is easier than replacement, it can be done only once, as additional layers of shingles would be too difficult to nail.

Since this project doesn’t involve tearing down existing materials, there is a risk you could end up missing problems affecting the underlayment and deck structure. However, if there are no signs of potential damage and there is only a single layer of shingles, reroofing may be the most time-efficient and affordable option.

What Is Roof Replacement?

Roof replacement is when all existing shingles and felt underlayment are removed and replaced with fresh materials. Additionally, contractors need to install new ventilation, flashing, and other essential components to protect the structure.

Replacement is advisable if you have room in your budget and schedule, as the tear-down process requires more labor time and costs. In the event you already have two layers of shingles, replacement is ideal.

If you have concerns about underlayment, replacement ensures all problems are addressed. However, if weather is bad, your home may be left exposed to the elements during construction.
