Why Choose Modified Roofing?

Modified roofing provides unparalleled resiliency and strength to your existing roof. Modified roofs are not only durable in the face of inclement weather and the elements but can also withstand foot traffic. Modified roofing keeps the colored granules in position, contributing to the roof’s stability while protecting it with its waterproofing properties for a premium roofing solution.

Types of Modified Roofing Systems

In-Ex Designs Roofing offers two main types of modified roofing, including hot application modified roofing and cold application. Depending on your needs, each type of modified roofing system offers its advantages and can drastically improve the protection and performance of your home’s roof.

Hot Application Systems

Hot application modified roofing, also called modified torch roofing, involves using heated roofing materials to create a resistant and watertight roofing membrane. This technique requires rolled roofing implemented with a torch to fasten the materials to the underlayment for a secure fit.

Cold Application Systems

Cold application modified roofing refers to the use of special adhesives that bond the materials without the use of heat. These systems, also known as self-adhered systems or peel-and-stick, are directly placed on the underlayment or base material, followed by a cap sheet applied over the adhesive to formulate the cold application modified roofing system.

Benefits of a Modified Bitumen Flat Roof

Choosing a hot or cold modified bitumen flat roof offers many advantages, including the following:

  • Energy-efficient
  • Cost-effective and low maintenance
  • Premium water and UV ray protection
  • Enhanced durability and weather-resistance

Enhanced Durability

Modified bitumen flat roof systems are durable and fire, water, and weather-resistant. They remain intact in severe weather conditions and have superior resistance to splitting and thermal shocks. Furthermore, they allow for a watertight barrier, deterring leaks and damage while protecting your home and roof.

Cost-Effective & Low Maintenance

The price of a modified bitumen roof system varies depending on the coatings and composition. Still, they are a cost-effective and affordable roofing solution due to the ease of installation. They also require minimal maintenance and can be easily repaired or maintained due to their easy-to-reach flat surface.


Modified roofing can be customized to accommodate rooftop HVAC units, solar panels, and beyond. Additionally, due to their versatile design options, they can be made to provide enhanced UV ray resistance, reflecting sunlight to regulate the temperature of your property for increased energy efficiency.
