A hot mop roof is the most effective way to cover your home’s flat roof. The results are very effective. It is a multi-layered roof covering that will last long if the roof is placed with adequate drainage and prevents pudding. It is one of the most inexpensive roofing solutions as well as durable.
Most commercial structures and other flat-top structures, including homes, have had tar and gravel roofs. Because of the techniques used, it is known as a hot mopping roof or built-up roof. It is a clay tile roof with an asphalt coating added on top.
So, in this article, I will discuss all the necessary information about Hot Mopping Roofs. By reading this article, I hope you will get all the information you need. So, let’s get started without delay.
9 Quick Steps To Set Up, Or Install Hot Mopping Roof
You must know that hot mopping is not recommended for residential roofs because it can be challenging to install and repair. If you consider installing the hot mopping for your roof, follow the step-by-step guide.
Step 1: Clean The Surface
The first thing you need to do is make sure that your roof’s surface is clean and free of debris. If there is any dirt or debris on the surface of your roof, it can prevent the asphalt from bonding correctly to the surface. It can lead to leaks and other problems.
Step 2: Repair The Damage
Next, you need to repair any damage on the surface of your roof. It includes cracks, holes, and any other damage that may have occurred. If you have any loose shingles, you should also replace them. After repairing the roof’s surface, you can begin the process of hot mopping.
Step 3: Apply Asphalt On Surface
The first step in hot mopping is to apply a layer of asphalt to the surface of your roof. The coating will serve as a barrier between the top and the tar. After using asphalt, you can then apply the tar.
Step 4: Apply Tar And Rosin Paper On The Surface
The tar is applied to a hot mopping machine. This machine will spread the tar evenly on the surface of your roof. Once the tar has been applied, you will now need to apply rosin paper along the length of the roof above it. You must use a staple gun to attach the rosin paper so that the rosin paper does not come out.
Step 5: Put The Layer Of Asphalt On Rosin Paper
Now you can apply a second layer of asphalt to the rosin paper. By doing so, you can prevent leaks. You can start installing shingles after finishing this second-level application. But you have to make sure that the shingles overlap each other.
Step 6: Install Flashing
Now is the time to cut and install flashing around the roof fixtures and inserts. You can use a plastic roofing flashing set to reduce leakage. These flashing shingles seal the edges and prevent water from entering your home.
Now you can apply a layer of asphalt over the flashing; this layer of asphalt will help keep the flashings in place and prevent them from moving.
Step 7: Use Tar On The Flashing
Then, you tar with a bucket or pump on top of it. You must apply tar, as it will prevent leakage. You must be safe when pouring hot tar, and others must be in a safe position. If necessary, shout out to everyone to get to a safe place. When it splashes, there is the potential for serious injury.
Step 8: Install Ridge Caps
You can then install ridge caps on the roof of your home. The ridge cap needs to seal the roof edges and prevent water from entering your home. Moreover, you can install a valley liner on the roof. This valley liner is mandatory to seal the edges of your roof and prevent water from entering your home. You can even apply tar on it to protect it.
Step 9: Put Pebbles On The Surface
You are almost in finishing touch. Now, you sprinkle light-colored pebbles evenly on your roof to protect it from the sun and weather. You do not have to do it if you have enough time to clean the ceiling after a week.
6 Reasons To Choose A Hot Mopping Roof
A heated mop roof is an excellent option for many reasons. The process is simple, efficient, and less expensive than tearing down and replacing an existing roof. Below I have mentioned some of why you should choose hot mopping:
1. No Need For A Complete Tear-Off:
Undoubtedly, one of the most significant advantages for commercial structures needing rapid, inexpensive, and dependable re-roofing services. A hot mop roof may be rapidly and simply installed on an existing ceiling as long as the weight does not exceed the structure’s capacity. It means that there is a lot of potential for cost savings on the overall job.
2. Long-Lasting:
When installed correctly, a hot mop roof will last for many years. It means that you won’t have to worry about re-roofing for a long time, saving you even more money in the long run.
3. Durable And Easy To Maintain:
A hot mop roof can withstand a lot of wear and tear, which is ideal for commercial buildings that see a lot of foot traffic or are in harsh weather conditions. The hot mop roof doesn’t require much maintenance, so you won’t have to spend much time or money keeping it in good condition.
4. Easy To Repair:
If there is ever any damage to a hot mop roof, it is easy to repair. The roofing material is applied in sheets, so one only needs to replace the damaged section to fix it. It can save you a lot of time and money in the long run.
5. Affordability:
A new roof covered with a hot mop is a cost-effective alternative for many homeowners. While this isn’t the most long-lasting roofing material on the market, it may be pretty affordable to homeowners who need to replace their roofs soon. This type of roofing material might need some maintenance in some cases.
6. Quick Installation:
The hot mop roof is simple to install. Depending on the number of installers, it takes two and three days to put an entire roof. Considering that a clay tile roof may take 2-3 days to complete, this is excellent news.
5 Tips To Make A Hot Mopping Roof More Convenient And Effective
Hot mopping is a process that has been familiar for a long time. It is a reliable and affordable way to install or repair a roof. However, there are some things that you can do to make the hot mopping process more convenient and practical. Here are some tips:
Tip 1: Clean Your Roof Properly
Your roof isn’t one of the components of your home that you would typically consider cleaning. However, it does require some upkeep from time to time. The good news is that the cleaning procedure is not overly complicated.
Spray water near the area where you believe the leak is emerging. As a result, you’ll be able to tell which specific portion needs to be fixed. When your roof is frozen, running water can cause severe damage.
Tip 2: Don’t Forget About The Gutters
When homeowners clean their roofs, it’s normal to forget about sewers. If your sewer is clogged, it could be the source of your leak. If you haven’t done this recently, it may be time to clean up your sewer.
After all, sewers collect rainwater and store it. If that water stays in one place for a long time, leaks will probably cause more severe problems. So, to make your hot mopping roof more convenient and practical, you must clean it.
Tip 3: Prevent Dry Rot
Another widespread misconception about dry rot is that it is caused by water. It has nothing to do with water damage. Dry rot happens for a lack of ventilation in the roof, not water damage. It’s one of the many issues you may encounter during the summer; therefore, having a roof evaluation is recommended.
The most straightforward approach to avoid dry rot is to install a ridge vent, which is impossible without the aid of an expert. A soffit vent is connected to a ridge vent and includes drilled holes. The house will then be cooled via the bottom through these openings, forcing the hot air out of it.
Tip 4: Avoid Any Ice Build-up
You also have a problem with dampness. Ice may block the roof membrane and gutters and shingles when it is cold. It becomes a significant problem because ice builds up behind your heating line. As a result, you will discover some interior dripping.
Third, keep in mind that the roof must be well ventilated. A drip edge may need to be installed by a professional depending on your location, type of roof, and house style. Rain shields and ice shields will also aid significantly in avoiding ice formation.
Tip 5: Insulate The Right Way
You’re probably aware that insulation improves your energy efficiency. However, it isn’t the only reason to Insulate Your Home Correctly. Good air circulation and ventilation are simple to accomplish. Ventilation is also necessary for avoiding dry rot, as previously stated.
By allowing the heat to pass through it, rigid foam insulation prevents your home from heat gain or loss. Installing a gap-free attic floor insulation is just one of many methods to insulate your house. You may also utilize a vapor retarder underneath the insulation close to the ceiling. This technique helps prevent dampness from rising into the attic.
Hot mopping is a quick, easy, and affordable way to install or repair a roof. You can make the process more convenient and effective by following these tips.

How to Remove a Hot Mop Roof
Due to the ever-changing and harsh weather conditions, roofs often require maintenance and re-roofing once or twice in a lifetime.
The re-roofing process involves a critical stage known as the “hot mop.” This process acts as a secondary barrier to safeguard the roof’s base sheet and maintain its watertight integrity. a rolled hot mop roof entails spreading hot asphalt onto the base sheet, then applying a 90LB felt or modified bitumen cap sheet, which is back-nailed to secure it. The materials used vary for flat and sloped roofs. Safety gear is crucial, given the process’s complexity and noxious fumes.
Professional roofing contractors manage the procedure meticulously, ensuring safety and minimal waste. ABC Roofing Corp, serving South Florida for over 30 years, prides itself on delivering excellent service and customer satisfaction.
How to Install Hot Mop Roofing
Hot-mopped roofs are cost-effective and durable solutions for low-pitch roofs, ideal when the rise is minimal (no more than 4 inches per foot). These roofs consist of layers of felt and asphalt over rosin paper, with added flashing around roof features. Reflective gravel or a cap sheet is applied to protect against sun damage and enhance appearance. However, the process releases fumes during asphalt liquefaction, contributing to smog. Hot mopping may have regulatory restrictions in some jurisdictions.
The hot mop roof installation installation process involves nailing cant strips at inside corners, laying rosin paper, securing base sheets with a 2-inch overlap, and adding flashing as needed. Molten asphalt is applied using a roofing mop in layers: base sheet, felt, asphalt, and repeat for a total of three layers (including the base sheet). To minimize UV damage, a layer of light-colored gravel is spread over the final hot-mopped layer. Alternatively, an aggregate-infused cap sheet can be used to reduce weight. Safety precautions are crucial, as hot asphalt can cause serious injury if mishandled.
