Understanding Modified Bitumen Roofing
Modified bitumen roofing is a time-tested solution for flat and low-slope roofs. It combines durability, waterproofing, and flexibility, becoming a favorite for commercial and residential properties.
The Core Material
These are asphalt-based, like BUR, but modified bitumen is crafted by combining asphalt with polymers to improve performance. These polymers, such as SBS or APP, promote the material’s flexibility, enabling it to endure extreme temperature changes without cracking. This flexibility is essential in shifting climates, like Calgary’s chilly winters and hot summers.
It’s beneficial because it can be installed on various roofing substrates, such as concrete, metal and plywood. This flexibility makes installation easier and provides a strong, waterproof bond to flat and low-slope roofs. For instance, on a commercial building with a concrete deck, modified bitumen offers fantastic adhesion and leak protection.
Two Main Types
Modified bitumen comes in two primary forms: SBS and APP. SBS-modified bitumen is extremely elastic, so it’s great for roofs that experience regular thermal expansion and contraction. APP-modified bitumen, conversely, is more rigid and UV resistant, working best in sunny, stable climates.
Installation methods vary. SBS can be cold-applied using adhesives or with self-adhesive sheets, while APP usually employs a torch-applied method. These options enable property owners to select the process most appropriate to their building’s requirements and budget.
Proven Durability
Originally developed in Europe in the 70s, modified bitumen has proven itself to be a reliable roofing system. When maintained and re-roofed every once in a while, they can last 60–75 years. Because they take 10–20 years to form, they age slowly.
Cost and Warranties
While modified bitumen is 20–40% more costly than the likes of TPO or EPDM, its longevity and warranties (often 10–30 years) make it worth the spend. It permits as many as two re-roofing cycles before replacement.
A Closer Look at SBS Systems
SBS roofing is a modified bitumen system for flat and low-slope roofs. Renowned for its versatility and ruggedness, it’s a perfect fit for places like Calgary that endure harsh temperatures and climates. Its expansion and contraction without cracking is dependable in residential and commercial applications. SBS systems provide superb waterproofing and energy savings.
The Flexible Solution
What SBS roofing shines at though, is handling building movement and temperature changes. Its flexible nature enables it to withstand freeze-thaw cycles, typical of Calgary’s climate, without cracking or leaking. Unlike regular roofing materials, SBS does not break down over time and is resistant to UV rays and other external forces.
That versatility means SBS roofing is perfect for a variety of uses, whether it be a house or a commercial property. Its capacity to keep up with structural expansion and contraction provides longevity into the range of 20-30 years, with some manufacturers even providing warranties.
Installation Methods
- Torch-On Application: Heat is used to bond the SBS membrane to the roof surface, ensuring strong adhesion.
- Cold Adhesive Application: A solvent-based adhesive is used to attach the membrane, avoiding open flames.
- Self-Adhered Installation: The membrane comes with a pre-applied adhesive layer, simplifying installation.
As previously mentioned, the SBS surface must be prepared adequately to properly bond. The certified roofing contractors must deliver the goods. Safety is important during the torch-on method as regulations must be followed.
Calgary Climate Performance
SBS roofing takes Calgary winters and hailstorms in stride. Its pliability stops cracking in the bitter cold, and its sturdiness holds strong against heavy snow and freeze-thaw cycles. This provides a reliable option for the city’s dynamic weather.
A Closer Look at Torch-On Systems
Torch-on roofing, more specifically SBS systems, is the ultimate modern-day roofing solution. This heat-applied membrane system provides not only unparalleled strength and durability but also does so in even the most difficult weather environments. Trusted and proven over time, torch-on roofing is most commonly utilized on flat and low-slope roofs, where it’s a favorite amongst commercial and industrial buildings.
The Rigid Protector
Torch-ons are like your shield against the elements – they prevent water from sneaking in, keeping your roof leak-free. The UV resistance ensures that it doesn’t crumble from years of sun exposure, just like a good sunscreen extends your life. Torch-on membranes don’t get dislodged in high winds or heavy rain. For flat roofs that experience heavy loads (think: HVAC units and constant foot traffic), the system’s strength delivers extra comfort.
The Application Process
The materials are applied with an open flame to fuse them on. Professional installers are a key to this technique, since accuracy matters to create a watertight bond. Torch-on systems are multilayered with a base sheet, all of which have been precisely glued for greater longevity. Safety precautions, including fire-resistant shields and ventilation, must be taken during application to reduce hazards. It’s easy to install for seasoned crews, but it requires care to achieve long-lasting results.
Calgary Climate Performance
Torch-on for Calgary’s weather unpredictability. It endures intense hail, a summer scourge, and bears heavy snow loads in brutal winters. Below freezing temps don’t make it brittle, while UV resistance guards it in sunny seasons. Over decades, this roofing system pays dividends, surviving Calgary’s weather extremes with practically no upkeep required.
The Calgary Showdown: SBS vs. Torch-On
Choosing the right roofing system is crucial for Calgary’s ever-changing weather. SBS vs. Torch-On for Calgary – comparing quality flat roof systems. So here’s an in-depth comparison of these systems, zeroing in on how they held up against Calgary’s unforgiving weather.
1. Cold Weather Flexibility
SBS roofing is superior in the extreme cold because it is rubberized and can flex without cracking in Calgary’s freeze-thaw cycles. This elasticity guarantees longevity, even with repeated temperature fluctuations. Torch-on systems, although robust, tend to be brittle in sub-zero temperatures, which can cause them to crack with age. When it comes to Calgary winters, SBS’s cold stress endurance would make it your best bet for a stable, flexible surface.
2. Hail and Impact Resistance
Calgary’s infamous summer hailstorms require impact-resistant roofing. Torch-on systems offer awesome durability and can often withstand hail punctures because of their layered nature. SBS roofing beats it; it takes the hits without breaking. Unlike torch-on, SBS’s elasticity prevents cracking when hit, which is perfect for flat roofs that get pelted by hail. Both systems are solid, but SBS provides extra durability for ongoing comfort.
3. Installation Safety
Torch-on roofing needs a torch, which can lead to fires. SBS roofing provides safer installation alternatives, frequently depending on adhesive or self-adhering membranes. Whichever system you opt for, hiring certified professionals is critical to make sure that it’s by safety rules and properly installed. This reduces hazards for installers and property owners.
4. Seam Integrity
SBS systems are created with seamless waterproofing in mind, meaning there is less chance of leaks. Torch-on systems can have seam failures down the road if not properly installed. Expert installation and regular maintenance are important to both systems to maintain seam integrity and prevent water damage, especially on low-slope roofs.
5. Long-Term Cost
SBS roofing requires a larger initial investment, with material costs 20%-40% higher than options like TPO or EPDM. Its low maintenance requirements and 20–30 life span make it worth the expense. Torch-on systems might be cheaper upfront, but more expensive to fix. When it comes to performance over time, SBS is a great value with superior longevity.
Beyond the Membrane: System Components
Flat roofing, in particular, SBS roofing, depends on carefully integrated components that provide durability, energy efficiency, and water resistance. An integrated solution is the secret to meeting Calgary’s tough climate. Below is an outline of essential system components and their roles in enhancing roof performance:
- Insulation: Maintains energy efficiency, reduces heating/cooling costs.
- Vapour Barriers: Controls moisture, prevents condensation damage.
- Flashing: Seals edges, prevents water infiltration.
- Waterproof Membranes: Shields against weather, extends lifespan (20-30 years).
- Adhesives & Mastics: Secure layers, seal penetrations.
Insulation Choices
Proper insulation is key for flat roofs. Rigid boards such as EPS, XPS, and Poly-iso are typical as well, offering structural support and thermal resistance. They promote energy efficiency by minimizing heat loss during winter and heat gain in summer, which slashes energy bills. For SBS systems, rigid insulation plays well with the membrane’s flexibility without sacrificing performance.
Vapour Barriers
Vapour barriers are moisture-resistant layers placed to avoid condensation in the roofing assembly. Without them, trapped moisture can rot insulation and eat away at roof longevity. SBS systems are compatible with vapour barriers and will perform well over time. It must be installed correctly—gaps or overlaps can result in system failure.
Flashing Details
Flashing shields vulnerable spots such as roof edges, seams, and penetrations. With top-notch materials like metal flashings, paired with SBS membranes, they provide superb waterproofing. Mastics and caulking seal connections to keep water out. Proper installation avoids leaks and lengthens roof life by tackling vulnerable spots.
Lifespan and Maintenance in Alberta
Roofing in Alberta is special because of its temperamental climate and high altitude. SBS and torch-on roofs – their lifespan and upkeep in Alberta Below is a breakdown of their expected lifespans and key maintenance considerations:
