Different Options Available for Flat Roof Replacement
Flat roofs are a popular choice for commercial and residential buildings. However, with time, flat roofs can deteriorate due to various factors such as weather conditions, lack of maintenance, and poor installation.
Three options available for flat roof replacement include built-up roofing (BUR), modified bitumen roofing (MBR), and single-ply membrane roofing (SPR). BUR is a traditional method that involves layering asphalt and felt while MBR is made up of reinforced asphalt layers. SPR is a modern option consisting of a single layer of thermoplastic or synthetic rubber material that offers durability and energy efficiency.
Built-Up Roofing
Built-up roofing, also known as BUR, is a traditional and reliable commercial roofing system commonly used on low-sloped roofs. It consists of multiple layers of roofing materials such as asphalt, felt paper, and bitumen that are built up to create a durable and waterproof membrane.
The installation process involves alternating layers of these materials with hot tar or asphalt to bond them together. This creates a seamless surface that can withstand heavy foot traffic and extreme weather conditions.
One advantage of built-up roofing is its longevity. With proper maintenance, it can last up to 30 years or more. Additionally, it provides excellent insulation properties which can help reduce energy costs for the building owner.
However, one disadvantage is its weight which may require additional structural support during installation. Furthermore, the installation process can be time-consuming and messy due to the use of hot tar or asphalt.
Overall, built-up roofing remains a popular choice for commercial buildings due to its durability and reliability in protecting against leaks and other forms of damage.
Modified Bitumen Roofing
Modified bitumen roofing is a modern version of built-up roofing that addresses some of its disadvantages while retaining the advantages. It is made by combining asphalt with modifiers such as APP (atactic polypropylene) or SBS (styrene-butadiene-styrene).
The resulting product is a flexible, durable, and long-lasting material that can resist punctures, tears, and weathering. Modified bitumen roofing comes in different forms such as torch-applied, self-adhering, cold-applied, and hot-mopped.
Each type has its own installation process and cost comparison with other flat roof systems.
To install modified bitumen roofing using the torch-applied method, a flame torch is used to heat the bottom layer of the material until it melts onto the roof surface. Self-adhering sheets are peel-and-stick products that require no heat source during installation.
Cold-applied adhesives use solvents or water-based solutions to bond the layers together without any fire hazard involved. Meanwhile, hot-mopped modified bitumen roofing involves heating up asphalt in kettles and then mopping it onto the substrate before adding more layers on top.
In terms of cost comparison with other flat roof systems like PVC or TPO membranes, modified bitumen roofing falls somewhere in between due to its flexibility and durability.
Single-Ply Membrane Roofing
Single-ply membrane roofing is a type of roofing system that has become increasingly popular in recent years due to its lightweight, flexible, and energy-efficient properties.
It is a low-slope roofing system that consists of a single layer of synthetic polymer-based material such as PVC (polyvinyl chloride), TPO (thermoplastic olefin), or EPDM (ethylene propylene diene terpolymer).
The advantages of single-ply membrane roofing are numerous. These roofs are easy to install, maintain and repair. They are also highly resistant to UV rays, chemicals, punctures, tears, and other types of damage.
One disadvantage of single-ply membrane roofing is that they can be more expensive than traditional built-up roofs. However, this cost can be offset by the savings in energy costs over time due to their reflective properties.
Another disadvantage is that these roofs may not be suitable for areas with extreme weather conditions such as heavy snowfall or high winds unless they are properly designed and installed with additional reinforcement materials.
Despite these drawbacks, the benefits of single-ply membrane roofing make it an attractive option for those looking for a durable and energy-efficient roof replacement solution.
Factors to Consider When Choosing a Replacement Option
When making a decision on the appropriate option for replacing an existing flat roof, it is crucial to consider various factors.
Durability is one of the most important factors to consider since flat roofs are more susceptible to damage from weather elements than sloped roofs. The replacement material should be able to withstand harsh weather conditions, such as heavy rain, snowfall, and strong winds.
Additionally, the cost-effectiveness of the replacement option should be considered. While some materials may be more expensive than others initially, they might save money over time due to their durability and low maintenance costs.
Environmental impact is another significant factor that should be taken into account when choosing a new roofing material. In today’s world where climate change has become a major concern, selecting an eco-friendly replacement option can help reduce your carbon footprint and contribute positively towards environmental conservation efforts.
Some factors that can help you determine if a roofing material is environmentally friendly include its recyclability and energy efficiency rating. Cost comparison is also an essential consideration since different roofing materials have varying prices depending on their quality and availability in your region.
Hiring a Professional Roofing Contractor
Hiring a professional roofing contractor is a crucial step in ensuring that the replacement process is carried out effectively and efficiently, with minimal disruptions to the occupants of the building.
