A well-designed roof is the ‘crown’ of your commercial building. It must be functional, while aesthetics is not always a priority. But if you are engaged in some industries where clients and customers come every day, it won’t hurt if this part of your facility is appealing.

A well-made roof will protect your building from bad weather and give strength to its structure for a long time. Numerous materials, roof systems, and construction techniques have been developed today. They can extend the lifespan of your roof up to several decades. Still, no rooftop is eternal. When it’s beyond its useful life, it’s time for action.

On the following link, inform about the importance of regular rooftop inspections:

Commercial re-roofing is a fast and efficient way to restore the roof’s appearance and provide an extra  layer of protection against the elements. This intervention is not as demanding and costly compared to roof replacement. But it will have the best effects when the rooftop is still in good condition, with no major damages.

What Is Re-roofing?

Commercial re-roofing typically involves applying a new coating over an existing layer. There’s no need for roof tearing; just exposing the deck when old and worn-out shingles are removed. A new layer will come to their places. It sounds simple, but this procedure needs good planning and material consideration.

Because the new layer comes over the existing one, the existing roof must be sturdy enough to support the new layer. Most commercial roofing systems can support the new layers. But they shouldn’t be damaged, and the deck must be in good condition. If not, you must make necessary repairs before re-roofing.

The new layer of shingles will protect the interior of the building while providing a cosmetic makeover for the exterior. Ensure you have licensed roofing contractors on this project, as it must be done with the utmost attention. You can visit this website for more guidelines on hiring professional roofers.

Materials Used

Popular materials include single-ply TPO (Thermoplastic Polyolefin) membranes, metal panels, PVC, and rubber (EPDM). Each of them has its good sides, so make sure you talk to an expert before making a final decision.

The latest innovations in roof systems are unmatched in the industry. These include metal and membrane coatings, both industry-leading choices for flat and low-slope buildings. They provide superior protection to the building and peace of mind for the building owner.

When Re-Roofing Is the Best Option

As already explained, re-roofing has no purpose if your roof is damaged or destroyed. This intervention is possible when there are fewer cracks on the shingles or edges curling near seams or plies. You can also spot them near flashings, skylights, and gutters.

These cracks and curls affect roof aesthetics more than functionality. They usually appear as a result of prolonged UV exposure and moisture. But some latent signs also indicate the need for re-roofing. These could be seam delaminations, cracked insulation that traps water, etc.

Building Permits

A proper re-roofing project should start with a thorough evaluation of the existing roof. There could be underlying problems that an untrained eye will miss. For example, installing a new roofing system over a deteriorated deck can cause bigger problems and more expensive repairs later. So you should leave the roof inspection to experts.

A professional roof inspection will provide you with all the necessary documentation to ensure that re-roofing is doable and safe. Also, these projects need building permits. Building codes may differ from state to state, so you should check those requirements with your local authorities.

You must submit your plans and paperwork and wait for the approval. If you do re-roofing without permission, you can face fines and prosecution. Also, you risk project suspension while the paperwork is processed.

Re-Roofing or Replacement

When it’s time to work on your commercial roof, it’s always good to consult roofing experts. You can even get a free estimate from SW Commercial Roofing and several other contractors before deciding on the best option. Of course, complex interventions cost more, but they are not always necessary. Roof replacement is necessary sooner or later. But, re-roofing at the right time can often save the day.

Complete roof replacement requires the removal of 100% of the old roof. It means exposing the entire deck to install new underlayment and fixing structural issues before covering it with new shingles. That’s a costly venture, but it can add value to your property. A new roof has the highest return on investment.

Re-roofing requires only 10% of the old roofing system. That’s a cheaper and faster solution to replacement. It employs fewer materials and labor, so this intervention can be less expensive than tearing off the entire rooftop. Instead of replacing the structure, you simply add a second layer of shingles to the existing one.

Re-roofing is an excellent option if your roof is in the middle of its lifespan. Unfortunately, that’s when early signs of deterioration usually appear. So you may want to take action sooner rather than later as it will help you retain the original appearance of your building.

Benefits of Re-Roofing

Re-roofing is much less time-consuming than a full replacement. One reason is that removing the old system and installing a new one will cut the time it takes to complete the project by over 50%. That’s significant because time is money, and you don’t want to waste either if not necessary.

Another benefit of re-roofing is that it requires less tear-off than exposing the entire deck. But when replacing a roofing system, it’s never advisable to install it over a wet or saturated roof. That may affect the performance of the newly installed system.

Furthermore, removing the entire roof requires a lot of labor and materials. Re-roofing allows you to remove only a portion of the old roofing system, which doesn’t require as detailed organization as a replacement. Also, you don’t have to schedule this intervention a few months ahead. You just need a few days with no rain and wind.


The most significant advantage of commercial re-roofing is that it costs far less than a traditional replacement. The main reason is that it requires less time and material than a complete roofing system replacement. You just need a new coating and supplies for its installation (adhesives, screws, patches, etc.).

This procedure is explained on the source below:

When restoring your commercial rooftop with a new coating, contractors apply underlayment and felt paper before. Then, they add a protective layer before restoring the roof’s aesthetics. This process is streamlined and includes skilled professionals with vast knowledge of materials and installation techniques. That ensures no idling and fast project completion.

The most common re-roofing cost is $360 to $2,185 per square meter (10×10 feet). Higher-end materials can double the cost of a new roof. But that still doesn’t mean they are the best solution for you. If the roof has significant water damage or is nearing its lifespan, re-roofing is not always the best solution.

Adding Strength to Existing Structures

Depending on the materials used, re-roofing can improve your roof’s functionality. Typically, a flat or low-pitched roof has three layers: surfacing, reinforcement, and weatherproofing. The layers all require some degree of weatherproofing and, in colder climates, ice protection.

Adding extra layers can bring benefits regarding improved sound and heat insulation, waterproofing, and moisture protection. But that’s possible only if you cover the structure that’s still in good condition.

Re-roofing a commercial building is an excellent way to enhance the overall quality and durability of the roof. Also, it strengthens the existing roofing system and provides your commercial building with a new look.

Easier to Schedule

Depending on the size of your commercial building, roof replacement can even require several crews that work on different tasks at the same time. That calls for excellent planning and organization. On the other hand, re-roofing is more efficient as it needs fewer people and tools to do the entire work.

Removing and installing a new deck can be troublesome due to nearby HVAC and gutter installations. These can further complicate the entire project. For you, it could mean work stoppage and delays. Luckily, that won’t happen when doing re-roofing. Skilled contractors can often do the work in a few days, with minimal disruption to employees or customers. Visit this page to see how to hire them.

Re-Roofing Disadvantages

While there are numerous benefits of re-roofing your commercial building, you must consider some disadvantages. As said, this intervention is not always feasible. It could be done on roofs with a single layer of shingles and no significant water or mildew damage. In any other case, it won’t work.

Also, re-roofing is not a temporary solution. It will provide seemingly better aesthetics and more strength to your rooftop. But it only masks the issues that will eventually appear. That’s the point where a roof replacement is a must.

Re-roofing adds weight to the structure of the building. A commercial building’s roof material can limit the number of layers that can be added. For example, asphalt shingles can only tolerate two layers of protection before necessary replacement. Also, poorly done re-roofing can make your rooftop look bumpy and uneven.

The re-roofing is relatively simple, requiring fewer resources, time, and artistry than the traditional roof replacement. As a result, it’s a less expensive, more efficient solution for commercial buildings that needs minor roof upgrades. Adding new layers adds strength and durability to the building without compromising aesthetics. But it’s not something you can do all over again, so make sure to talk to experts before deciding on this intervention.
