Rolled Roofing: An In-Depth Guide for Homeowners
Choosing the right roofing material is crucial for protecting your home or commercial property. While traditional shingles are popular for sloped roofs, flat or low-slope roofs require a different solution. Rolled roofing offers a versatile and durable option that is increasingly favoured in Atlanta, Georgia.
Rolled roofing includes a variety of materials designed specifically for low-slope applications, suitable for everything from residential flat roofs to large commercial buildings. These materials are supplied in rolls, making installation efficient and providing a seamless, watertight finish.
However, the array of options, such as modified bitumen, TPO, and PVC, can make selecting the best-rolled roofing material challenging.
For rolled roofing projects, partnering with a reputable contractor like Southern Premier Roofing is crucial. Our expertise ensures the selection of appropriate materials and ensures proper installation, delivering long-lasting protection and peace of mind for years to come.
What is Rolled Roofing?
Rolled roofing refers to a range of materials tailored for low-slope or flat-roof installations. In contrast to traditional shingles, which are intended for shedding water on sloped roofs, rolled roofing materials create a seamless, watertight membrane that offers robust protection from the elements.
Difference from traditional shingles
Traditional shingles, like asphalt or composite types, are engineered to overlap and interlock, forming a layered system that guides water down the roof slope. Yet, this design proves ineffective on flat or low-slope roofs, where water pooling can lead to leaks. In contrast, rolled roofing materials are installed as a continuous sheet, forming a seamless, watertight surface capable of enduring ponding water.
Suitable applications for rolled roofing materials
Rolled roofing is highly versatile and suitable for various applications, such as:
- Residential roofs with flat or low slopes
- Commercial and industrial buildings featuring flat or low-slope roofs
- Outbuildings, sheds, and other structures with flat roofs
- Re-roofing or roof recovery projects on existing flat or low-slope roofs
Types of Rolled Roofing Modified Bitumen Roofs
- History and development :
- Modified bitumen roofing originated in the 1960s as a substitute for traditional built-up roofing systems. It blends asphalt with reinforcing materials such as fibreglass or polyester.
- Construction and composition :
- Modified bitumen roofing generally includes a base sheet, a reinforced membrane, and a granular surface layer. These components are crafted to offer durability and superior weather resistance.
TPO Roofing
Definition and popularity :
TPO, short for Thermoplastic Polyolefin, has risen as a leading choice among rolled roofing materials for commercial use. This single-ply membrane is renowned for its energy efficiency, reflectivity, and resistance to chemical exposure.
- Installation process and characteristics :
- TPO roofing is installed using large rolls that are secured to the roof deck using specialised plates and screws or adhesives. The seams are then heat-welded to form a seamless, watertight seal.
Colour variety and residential suitability :
TPO roofing is primarily available in white or light colours to maximise energy efficiency. Some manufacturers may offer limited options such as gray or black. Its strong performance and durability make it suitable for residential flat roofs, though aesthetic preferences should also be considered.
PVC Roofing
Comparisons between PVC and TPO: PVC (polyvinyl chloride) roofing shares similarities with TPO in installation methods and single-ply membrane construction. However, PVC stands out for its exceptional resistance to grease, oils, and specific chemicals, making it a favored option for restaurants and industrial applications.
Advantages in specialized applications (e.g., restaurants): PVC roofing’s outstanding chemical resistance makes it perfect for restaurants, where grease and kitchen vent exhaust can deteriorate other roofing materials.
Cost and recent trends: PVC roofing typically commands a higher price compared to TPO. Recent advancements in TPO technology have enhanced its cost-effectiveness in numerous scenarios. Nevertheless, PVC continues to be favored in specialized applications where its superior chemical resistance is essential.
Installation Methods for Rolled Roofing
Torch-applied method: In this technique, the rolled roofing material is heated with a torch, activating the sealant and ensuring it adheres to the substrate.
Adhesive method: This method involves applying a specialized adhesive to the roof deck, onto which the rolled roofing material is laid and bonded.
Self-adhering method (popular in residential applications): Self-adhering rolled roofing membranes come with a pre-applied adhesive layer, eliminating the necessity for torches or extra adhesives. This method has become increasingly popular in residential applications for its simplicity of installation and safety benefits.
Expected lifespan and factors affecting durability: With correct installation and regular maintenance, rolled roofing systems can endure for 20 years or longer. However, factors such as climate, weather conditions, foot traffic, and adherence to manufacturer guidelines can impact the overall lifespan and durability of the roofing system.
Choosing the Right Rolled Roofing Material
Assessing your roof’s slope and conditions: The initial step in choosing the right rolled roofing material is assessing the slope and current condition of your roof. Rolled roofing is tailored for low-slope or flat roofs, but various materials may be more suitable for specific slope ranges. Moreover, considerations like the age and state of the existing roof deck can impact the selection of roofing material and the method of installation.
Considering climate and weather in Atlanta, Georgia: Weather and climate conditions in Atlanta, Georgia, are pivotal factors in selecting the optimal rolled roofing option. Materials such as TPO and PVC are renowned for their resilience against UV rays and temperature changes, making them well-suited for the region’s diverse weather conditions. Additionally, when choosing a material capable of enduring extended exposure, it’s essential to consider the possibility of ponding water on flat roofs.
Balancing cost, performance, and aesthetic preferences:
While performance and durability are crucial, factors such as cost and aesthetic appeal should also be considered when selecting rolled roofing materials. TPO and modified bitumen roofing typically offer cost-effective solutions, whereas PVC roofing, despite being more expensive, provides superior chemical resistance. Additionally, if the roof is visible from the ground or surrounding areas, the color and appearance of the material may influence the overall aesthetic of your property.
The Importance of Professional Installation
Potential pitfalls of DIY or inexperienced installation:
Attempting to install rolled roofing yourself or hiring inexperienced contractors can result in costly mistakes and premature roof failures. Improper material handling, inadequate seam sealing, and incorrect attachment methods can compromise the roof’s watertight integrity, leading to leaks, ponding water, and potential structural damage.
