What is Modified Bitumen Roofing?
Modified bitumen roofing systems are flat or low-slope roofs made from asphalt that has been enhanced with modifiers like APP (Atactic Polypropylene) or SBS (Styrene-Butadiene-Styrene). These modifications give the roof improved elasticity and UV resistance. Often used in commercial settings but also suitable for residential applications, modified bitumen can be installed using various methods such as torch down, cold adhesive, or self-adhered systems.
How Does Modified Bitumen Compare to Other Roofing Systems?
When considering your roofing options, it's essential to compare modified bitumen with other materials:
- Asphalt Shingles: While asphalt shingles are popular for pitched roofs due to their affordability, they don’t offer the same level of waterproofing as modified bitumen.
- TPO Roofing: TPO (Thermoplastic Olefin) is a single-ply roof membrane known for its energy efficiency but may not hold up as well under extreme conditions compared to modified bitumen.
- EPDM Roofing: EPDM (Ethylene Propylene Diene Monomer) is another flat-roof option that offers excellent longevity but can be less flexible than modified bitumen.
Understanding these comparisons will help you make an informed decision about the best roofing system for your needs.
The Components of Modified Bitumen Roofing Systems
To comprehend how modified bitumen works effectively, it's important to understand its components:
1. Base Sheet
The base sheet serves as the foundation of the roofing system and provides stability.
2. Modified Bitumen Membrane
This is the primary layer that offers waterproofing capabilities and resilience against weather elements.
3. Insulation
Insulation layers can improve energy efficiency by reducing heat loss during winter months.
4. Surfacing
Granules or coatings on top of the membrane provide UV protection and enhance aesthetic appeal.
Benefits of Modified Bitumen Roofing

Regular inspections are necessary to ensure that seams remain intact and there are no leaks due to wear and tear.
Installation Methods for Modified Bitumen Roofing
Modified bitumen can be installed using several techniques:
1. Torch Down Method
This method involves heating the underside of the membrane with a torch before adhering it to the roof deck—ideal for experienced roofers due to safety concerns.
2. Cold Adhesive Installation
Involves applying a cold adhesive instead of heat; it’s simpler but requires meticulous application for long-lasting results.
