Commercial Re-roofing vs. Commercial Roof Replacement

It is normal to have confusion about the differences between re-roofing vs. replacement. We’ll explain each to help you understand the differences.

Roof replacement involves removing your old roofing materials from your roof. The decking is inspected, and the water-resistant underlayment is replaced. A new layer of roofing is then installed on the roof.

Re-roofing allows you to skip the removal of the old roof. Roofers instead install the new roof system over the old one.

Re-roofing is the opposite of roof replacement, which removes the old roof. It simply applies a brand new roof over top. As you can imagine, there are some advantages and disadvantages to this. Let’s look at some of the things you should think about before making a decision on a commercial re-roofing project in Florida.

Commercial Re-roofing: Pros and Cons

Commercial re-roofing can be a great option, but sometimes it’s better to replace the roof completely. Let’s start by looking at the many reasons why commercial re-roofing might be right for you.

Pros of Commercial Roof Re-roofing

1. Cost: The most important advantage of re-roofing is the price. Re-roof is always more affordable than replacement because it does not require the removal and disposal of your entire old roof. Re-roofing is a good option for those who don’t want to spend money on a complete roof replacement.

2. Time: Many businesses do not want roofers on their property, particularly if they are a seasonal company in the middle of its busy season. Commercial re-roofing can be a great option in these situations because it is much faster than removing and replacing an old roof.

3. Double Protection: When you choose a commercial roof re-roofing you get twice the protection. Your new roof will sit on top of the old one, so water will have to travel twice as far before it can reach your building. This is great for flat roofing since they are more susceptible to standing water.

4. Aesthetics: Commercial re-roofing revitalizes the look of your roof. Covering your old flat roof with a new one can give it a “new roof look” without the “new roof price tag”.

Cons of Commercial Roof Re-roofing

1. Usability: Not all roofs are eligible for commercial re-roofing. You can only have 2 roofing systems on the same structure at once, so it’s not possible to re-roof a roof twice. A roof that has been significantly damaged may also not be suitable for re-roofing. If you have heavy leaks on your roof, structural damage may exist that can’t be fixed by re-roofing. In this case, a roof replacement for a commercial building would be the best option.

2. Lifespan: When compared to roof replacement, a roofing job will not last as long. The materials used will determine how long the roofed-over roof will last. Modified asphalt, TPO, and EPDM roofing are common for commercial re-roofing.

3. Assurance: When you replace your roof, you can be sure that the entire roofing system will work. When you opt for commercial re-roofing, there is no access to the roof’s underlying structure. Re-roofing won’t reveal any existing damage.

FAQs about Re-roofing

1. What is re-roofing, and why do you need it?

   A: Re-roofing involves installing a new roof without removing the existing one. Roof replacement is the process of tearing off your old roof and installing a new roof in its place.

2. Q: When should you re-roof instead of replace?

   A: Re-roofing is a time and cost-effective option as you don’t have to remove your existing roof. This is the most common option when an existing roof still has structural integrity but needs to be upgraded or repaired.

3. Q: What is the benefit of commercial re-roofing for businesses?

   A: Re-roofing is a cost-effective way to extend the life and energy efficiency of an existing roof. It can also address minor problems without having to replace the entire roof.
