The Hot Mop Technique Requires Specialists

Hot mop roofs are affordable and durable, particularly for commercial buildings with large roof areas. They are often installed on flat roofs or roofs with a negligible low slope and can even be installed on existing roofing material, as long as your home or building can withstand an extra weight on the top. 

Hot mop roofs are made with consecutive layers of rosin paper and molten asphalt. The liquid asphalt is heated at 400 degrees Fahrenheit and then spread on the flat roof with a special mop — which gives this type of roof its name. These three layers of insulating material are topped off with a layer of gravel or stones. In between the layers of asphalt, you must install flashing to seal the edges of the roof and around vents and chimneys. Hot mop roofs can withstand harsh weather, including the sun’s UV rays, for up to two decades.

Handling such hot and dangerous material requires expertise and training as well as the right tools and protective gear. Likewise, the proper installation of the flashing means that your roof will be fully insulated and waterproof. 

An expert like Golden Heights can install, replace, or repair your hot mop roof.

Benefits of Hot Mop Roofs

Affordable roofing material and roof repair

Hot mop roofs are affordable and more budget-friendly than other types of roofs. This type of roofing is one of the most cost-effective options for large surfaces like commercial buildings or commercial roof repair. 

Excellent waterproofing qualities

Thanks to the successive layers of rosin paper, hot liquid asphalt, and felt, hot mop roofs create a waterproof layering that provides protection from harsh weather conditions. 


Hot mop roofs are durable and can easily last for 15 years or more. They require minimum maintenance and are highly scalable if you are building an extension of the existing building. 

Hot mop can be installed on existing roofing material

There is no need to tear off the existing roof. As long as the building withstands the weight of the hot mop, you can easily install it over the existing roof. This saves time and money for home and business owners.

In some cases, a hot mop roof can be applied over an existing roof. This, however, depends on the condition and type of the current roofing system. A professional roofing contractor from Golden Heights will assess the existing roof to determine whether it is a viable base for a new hot mop application.

If you want a longer lasting hot mop roof, our roofers are ready to discuss the best roofing options for your home with you.

Yes, but it’s best to avoid doing so. While hot mop roofs are durable, it’s best to walk on them cautiously and only when necessary to prevent potential damage. If you must walk on them, use walk pads or boards for distributing weight and avoid any fragile areas or components.
