You’ve probably heard of “wrap roofing” before. After all, it’s one of the most popular types of roofing available today.
But what exactly is it? How does it work? And how is it installed?
In this article, we’re going to answer all these questions and more!
What is shrink-wrap roofing?
Shrink wrap roofing is a temporary roofing solution that involves wrapping a building’s roof with a plastic film material and then heating it with a propane torch to shrink the film and create a tight, waterproof seal over the roof surface.
The plastic film used in shrink-wrap roofing is typically made from a polymer-based material such as polyethylene, polyvinyl chloride (PVC), or polyolefin and is available in various thicknesses and colors.
Shrink wrap roofing is often used as a temporary solution to protect buildings that have been damaged by fire, storms, or other natural disasters, or during construction or renovation projects when a permanent roof is not yet in place.
However, it is not recommended as a long-term solution for residential roofing as it is not as durable or weather-resistant as other roofing materials.
Why would you need shrink-wrapped roofs?
Temporary protection
Shrink wrap roofing can provide temporary protection for your home’s roof during repairs, renovations, or emergency situations where a quick fix is needed.
Weather protection
Shrink-wrap roofing can help protect your roof and home from extreme weather conditions such as heavy rain, snow, wind, and hail.
Leak prevention
Shrink-wrap roofing can provide a barrier against leaks and prevent water from entering your home, which can cause damage to your interior and possessions.
How does shrink-wrap roofing work?
Shrink-wrap roofing is a relatively simple process.
First, the roofing contractor will clean and prepare the roof surface, making sure it is free of debris and any sharp edges that could puncture the plastic film.
Then, the contractor will lay out the plastic film over the roof surface, making sure it is large enough to cover the entire area.
The film is then secured to the roof surface using strapping, taping, or other fasteners to prevent it from blowing away in the wind.
Next, the contractor will use a propane torch to heat the plastic film, which causes it to shrink and tighten around the roof surface, creating a tight seal.
The heat also causes the plastic to conform to the shape of the roof and any obstructions, such as chimneys or vents. This helps to create a uniform, waterproof seal over the entire roof surface.
Once the shrink-wrap roofing is in place, it can provide temporary protection for the building from the elements, such as rain, snow, and wind.
However, it is important to note that shrink-wrap roofing is not a permanent roofing solution and should only be used as a temporary measure.

How effective is shrink-wrap roofing at preventing leaks?
Shrink-wrap roofing can be effective at preventing leaks when installed correctly. The shrink wrap material creates a tight, waterproof seal that can help protect the roof and the interior of the building from moisture-related damage.
The thickness of this wrap can measure about 300 microns, which is considered a good thickness for waterproofing.
However, the effectiveness of shrink-wrap roofing will depend on a few factors, including the quality of the material, the skill and experience of the installer, and the specific conditions of the roof.
How to install shrink-wrap roofing
- Assess the roof: The first step in installing shrink wrap roofing is to assess the condition of the roof and determine if shrink wrap roofing is a suitable solution. If there are any underlying issues with the roof, such as leaks or structural damage, these issues must be addressed before the shrink wrap is installed.
- Measure the roof: Measure the roof to determine the size and shape of the shrink wrap material needed. The shrink wrap should be cut to fit the roof exactly, leaving no gaps or areas where water can penetrate.
- Prepare the surface: The surface of the roof should be clean, dry, and free of any debris or obstacles. The roof may need to be cleaned or repaired prior to the installation of the shrink wrap.
- Install the shrink wrap: The shrink wrap is installed using specialized equipment that heats the material, causing it to shrink and form a tight, waterproof seal over the roof. The shrink wrap should be stretched and secured tightly to the roof to ensure a proper fit and prevent water from pooling.
- Inspect and maintain: Once the shrink wrap is installed, it should be inspected regularly for any signs of damage or wear. Any damage should be repaired immediately to prevent water from seeping through. Additionally, any snow or ice buildup should be removed from the shrink wrap to prevent excessive weight and stress on the roof.
