Re-roofing vs. Roof Replacement, What Is Right For Me?

A failing roof is every homeowner's worst nightmare. Whether the roof is leaking or has suffered some structural damage, it's always best to fix the problem upfront. For many people, resolving common roof problems narrows down to two roof repair options – re-roofing or roof replacement.

To help you choose the best option from the two, we've discussed the re-roofing and roof replacement differences, key considerations, their pros and cons, and everything in between.

Re-Roofing Vs. Roof Replacement

Re-roofing is the process of adding a new layer of roof, such as roof shingles over an existing roofing material. Since there's no tearing off the old or damaged roof, this process is fast and less costly. However, it doesn't fix the underlying roof issues, such as a rotting roof deck, plus it can be done only once. This is because there's a risk of piling too much weight on the roofing structure.

On the other hand, roof replacement is a more thorough process. It involves tearing off the old or damaged roof before putting on a new roofing layer. Roof replacement is best done when re-roofing isn't an option, and more underlying roof issues have to be fixed. Because of how comprehensive the process is, roof replacement is labor and skill-intensive and is more expensive.

Re-roofing and Roof Replacement Considerations

A roof that's nearing the end of its lifespan could develop structural issues such as leaks or missing shingles. If you have just one roofing layer installed, you can opt for a re-roof. This will further extend the lifespan of your roof while restoring its form and beauty. And while this option is attractive to most homeowners, it's not always the best.

For homeowners looking for the best results from their roof renovation project, a roof replacement will do. The latter comes with more benefits as it fixes water damage issues on the attic and decking. It also gives your roof a completely new look.

Here are some of the factors to consider before going for a re-roof or a roof replacement:

The Extent of Damage

Re-roofing is done to a roof that's still in good shape but has suffered minor damage. The damage would often be physical, such as curled edges or missing granules on asphalt shingles. If the damage is due to rot or mold build-up, a re-roof could easily hide these adverse roof issues. That way, you'll only be addressing the symptoms and not the root causes of the problem.

For advanced roof issues, a roof replacement is the best option. If the roof looks worn with dark streaks all over, it's a sign of advanced water and mold damage. Here, it's recommended to tear off the old roof and inspect the entire roofing structure for further damage. The roofing technician will also inspect the framing, deck nailing, and the strap & shear.

Cost

Cost is the other determining factor that plays a critical role when choosing from the roof repair options. More often, re-roofing is cheaper than replacing the entire roof. The process of tearing off the old roof material, inspecting & preparing the decking, then replacing a new roof adds to the roofing cost.

That said, a re-roof can be done by one or two people, while a roof replacement may require the use of specialized roofing equipment. This will further call for more labor and hence higher cost. If you are on a budget, a roof replacement may not be an instant solution. You may need to re-roof the damaged or leaking part of the roof to fix the problem at hand as you prepare financially for a roof replacement.

Before judging which option is costlier, you may want to use a roof replacement cost calculator to get the exact figures and wisely weigh the two options. 

Aesthetics

Your roof makes up a large portion of your home, and it's the focal point of your property's exteriors. If your roof is worn out and old, it kills your home's overall aesthetics. Many homeowners would choose to clean and re-paint their roofs once the color begins to fade. But this isn't always an option if the roof is damaged as well.

Depending on the level of damage and whether the entire roof is worn out, you can go for a re-roof or a roof replacement. A re-roof will work if there's a small damaged portion and the entire roof looks clean and new. You'll only need to match the colors and texture of the roofing materials to preserve the aesthetics.

If the damage is huge, a roof replacement will work best. Here, you'll go for a roofing material within your budget and that will further enhance your home's curb appeal.

Get Help with Your Roofing Needs

Before outright deciding to go for a re-roof or a roof replacement, you want first to schedule a professional roof inspection. This will help unearth the level of damage and the necessary steps to take to restore the integrity of your roof.

For the best results, choose a roofing contractor who will listen to your needs. The contractor should also customize their services to meet your expectations. Doing your research and reviewing the contractor's past projects and customer reviews will help you make the right choice.
