Modified Bitumen
A durable roofing system that has stood the test of time - modified bitumen roofing systems were first introduced in the mid 1960's and continue to be one of the most widely used low-slop roofing systems today.
Benefits of a Modified Bitumen Roof
Modified bitumen is an excellent commercial roofing system because it is resistant to heavy foot traffic, punctures, and tears. Featuring plastic- or rubber-based polymeric binders in its formulation, modified bitumen is flexible and expands or contracts with the building, making it suitable for many different climates.
One reason why modified bitumen is one of the most popular roofing systems is how easy and quick the installation process can be for an experienced production crew. A quicker roof installation often times results in reduced labor costs, potentially saving you thousands on your new roofing system.
Modified bitumen sheets are manufactured under tight quality control, resulting in consistent thickness. Manufacturers assemble the torch-preparation linings, waterproofing binder, weather-resistant surfacing, and fabric reinforcement into sheets with uniform physical properties and thickness. This consistency guarantees a reliable and proven performance from the product.
An often overlooked benefit of asphalt-based roofing systems, like modified bitumen, is their compatibility with off-the-shelf roof repair products. While most leaks require the expertise of a roofing professional, some can be repaired simply by applying a bit of roofing cement. Often times, building managers and owners fail to realize that asphaltic repair products, such as roofing cement, is incompatible and ineffective on modern single-ply roofs.
The Mechanically Fastened/Attached System uses fastening plates to secure the membrane. This system provides faster installation times without the use of adhesives and seam tapes. Membrane seams are then heat-welded with specialty hot-air equipment. Mechanically attached is the most prevalent method of installing TPO membranes.
The Fully Adhered System uses TPO bonding adhesive to adhere and secure the TPO membrane to the insulation board or recovery board. This method does not require the use of fastening plates to secure the membrane. Membrane seams are then heat-welded with specialty hot-air equipment.
Frequently Asked Questions
A commercial roof replacement involves completely removing the existing roof system and installing a new one, while a roof recover/layover involves installing a new roof system over the existing one without removing it.
Several factors come into play when deciding between a roof replacement and a roof recover/layover. These include the condition of the existing roof, its age, the extent of damage, and local building codes. Our roofing experts can assess your roof and provide you with a professional recommendation.
Roof recovers/layovers are possible on certain types of commercial roofs, such as single-ply or modified bitumen systems. However, not all roofs are suitable for this method, and it depends on factors like the condition and structural integrity of the existing roof. Our team can evaluate your specific roof to determine if a recover/layover is feasible.
A commercial roof replacement offers several advantages, including improved energy efficiency, enhanced durability, increased lifespan, and the opportunity to incorporate modern roofing materials and technologies. It also allows for a thorough inspection of the roof deck and underlying structure, ensuring any underlying issues are addressed.
Roof recovers/layovers can provide cost savings and shorter installation times compared to full replacements. They can be a viable option if the existing roof is in relatively good condition and can provide an additional layer of protection. However, it's essential to consider the long-term implications and consult with our professionals to determine the best course of action for your specific roof.
At Economy Roofing, we offer comprehensive warranty options for both commercial roof replacements and roof recovers/layovers. The specific warranty coverage will depend on the type of roofing system and materials used but typically they range from 10-20 years. Our team will provide detailed information about the warranty terms and conditions associated with your specific project.
The timeline for completing a commercial roof replacement or roof recover/layover can vary depending on several factors, including the size and complexity of the project, weather conditions, and material availability. Our experienced roofing team will provide you with an estimated timeline during the initial consultation. We strive to complete projects efficiently while ensuring the highest quality workmanship.
