Is your commercial roof in need of repairs? Regardless of who you are, it can be stressful to have a roof that isn’t working for you - especially when it comes to deciding what to do with it. The truth is, there are two options to choose from: a full roof replacement or re-roofing. You can either place new shingles on top of the existing shingles or tear up the shingles and do a complete roof replacement.
Before you choose one of the two, it’s essential to understand your options, when you should choose a full roof replacement, and when you should opt for commercial re-roofing.
The Basics of Commercial Roof Replacement
What is Commercial Roof Replacement?
To expose the roof deck, a roofing contractor will tear everything off, exposing the deck. They will then install a new underlayment or felt to protect the roof deck from elements. Finally, they will completely recover the roof with new shingles and repair or replace any flashing or edging.
A roof replacement should last for at least 20 years and can be done no matter how many layers of shingles are already on the roof, which means it can be done when re-roofing isn’t an option. Due to the extra labor involved, a new roof can also be more expensive.
The Pros of Commercial Roof Replacement
As a worthwhile investment, a commercial roof replacement provides the following benefits:
- You get an entirely new roof
- The installation will be stronger because there is nothing between the new roofing materials and the roof deck
- The roofing materials will last longer than with a re-roof
- It adds value to the property if you decide to sell it in a few years
The Cons of Commercial Roof Replacement
The drawbacks of a commercial roof replacement include:
- It is more disruptive than to operations than re-roofing
- It may be necessary to expose portions of your building when removing your old roof
- Mechanical and HVAC installations on your roof can cause complications
- It is more expensive than re-roofing due to the extra labor
The Basics of Commercial Re-Roofing
What is Commercial Re-Roofing?
Typically, re-roofing costs less than replacing your roof because it uses fewer materials than a full roof replacement. However, even though it’s less expensive, it’s not always the best option.
With re-roofing, a roofing contractor will place a new shingle overlay over your worn shingles, exposing the deck. They’ll apply an underlayment or felt paper to the deck to protect it from water and other weather elements.
The new shingles will then be installed on top to restore the look of your roof and provide a protective layer to help leaks from getting inside your commercial building.
The Pros of Commercial Re-Roofing
If you’re hoping to save money, commercial re-roofing is a great option that provides the following:
- The second layer of shingles adds an extra layer of strength to your roof
- The new layer of shingles also gives your roof a facelift
- The process is relatively simple and takes a lot less time than a full roof replacement
- Re-roofing is inexpensive because it uses fewer materials than a full roof replacement
The Cons of Commercial Re-Roofing
Despite its advantages, there are also disadvantages to commercial re-roofing:
- Works for roofs with one layer of shingles
- Doesn’t work for roofs with extensive water damage or mildew growth
- Can make your roof look uneven if it’s partially damaged in certain areas
- Will only disguise problems that eventually reappear in the future
Commercial Roofing Replacement vs. Re-Roofing: Which One Should You Choose?
If you only have one layer of shingles on your roof, you may be a candidate for commercial re-roofing. It may also be a good idea if you have a roof that is nearing the end of its lifespan and is in overall good shape, or there are only minor issues or leaks.
However, re-roofing isn’t always a great idea, especially if your roof has experienced significant water damage, or there are large amounts of moss or mildew growth. It can also add additional weight to the roof structure and may not be as aesthetically pleasing as a roof replacement.
You may want to consider a roof replacement if your roof deck has experienced extensive water damage, has a lot of mildew or mold growth, or is sagging. Plus, it’s always a safer and longer-lasting option.
