Introduction
Selecting the appropriate roofing material requires careful assessment to ensure it suits the property’s functional and structural needs and meets regulatory requirements.
The material selection also impacts energy efficiency, durability, and budget. Modern roofing solutions provide superior insulation that helps regulate indoor temperatures.
On the other hand, assessing material durability is vital as commercial buildings are often exposed to more significant environmental stresses due to their size.
5 Key Factors to Consider When Choosing Roofing Materials
When selecting roofing materials, businesses often prioritize price differences. However, the initial cost is not the only factor to consider when investing. Choosing materials for their durability, resistance to environmental hazards, and building purpose provides better long-term investment.
The main factors to consider when selecting roofing materials are:
1. Climate and Environmental Conditions
Understanding local climate and environmental conditions is a foundation for material selection, as it enables businesses to tailor their choice to ensure longevity and long-term energy efficiency.
Colder regions with heavy snowfall require durable materials such as EPDM to handle heavy loads while preventing water penetration.
Meanwhile, businesses should prioritize materials that deflect heat, such as TPO or PVC, in areas with high temperatures and sun exposure. Choosing these in warmer regions helps save energy and reduce cooling costs.
2. Building Purpose and Design
The purpose and design play a significant role in determining the most suitable roofing material – a roof for an office building must meet different functional and aesthetic requirements than one designed for a storage facility or industrial warehouse.
Buildings such as warehouses or manufacturing facilities, where functionality outweighs aesthetics, need to prioritize durable materials. Conversely, office buildings or retail spaces may require a visually appealing finish to align with the architectural design and brand image.
3. Budget and Lifespan
The return on investment (ROI) for various roofing materials varies depending on the material’s longevity, ease of maintenance, and energy efficiency.
Metal, EPDM, and TPO are known for their durability, usually lasting 30 to 50 years. Lower maintenance fees and a longer average life span compensate for higher initial costs when choosing these materials.
On the other hand, asphalt and modified bitumen are more affordable options that still provide good performance.
4. Sustainability and Energy Efficiency
The ability of roofing materials to reduce energy consumption reduces costs while benefiting the environment. The reflective properties can help regulate a building’s internal temperature and reduce the need for excessive heating or cooling.
On the other hand, materials like recycled metal, green roofs, and solar roof systems offer sustainability and energy efficiency.
Look for ENERGY STAR or LEED certifications to meet sustainability and energy efficiency standards.
5. Building Codes and Regulations
Compliance with local laws is essential, as each region may have specific codes regarding fire resistance, wind loads, insulation, and overall structural integrity. These codes must be adhered to for the roof to pass inspections and meet safety requirements.
Roofing companies experts are familiar with codes and can guide local standards. Consulting with a professional ensures that the selected roofing system is compliant and optimized for the building’s needs, preventing costly delays or modifications later in the process.
Popular Roofing Materials for Commercial Buildings
Popular materials for commercial buildings include:
1. Metal Roofing
Steel, copper, aluminum, and other metal materials are known for their durability and resistance to environmental hazards. Additionally, metal roofing is highly versatile, providing for various commercial applications, from warehouses and manufacturing facilities to office buildings and retail spaces.
2. TPO and PVC Membranes
Thermoplastic materials such as polyvinyl chloride (PVC) or thermoplastic olefin (TPO) are in increasing demand. Roofs made of these materials provide resistance to UV radiation and chemical damage. However, the initial costs of installation and insulation may be higher than those of other materials.
3. EPDM Roofing
Ethylene Propylene Diene Monomer is a weather-resistant solution for flat or low-slope roofs. Its main advantage is its resistance to UV radiation and lifespan of 25 to 30 years.
4. Built-Up Roofing (BUR)
Bilt-up roofing is created by installing multiple layers of asphalt or bitumen and reinforcing them with felts or textiles. BUR roofs have long lifespans and resist high foot traffic, water, and UV damage. However, their weight requires a strong foundation, and the installation takes longer than other materials.
5. Asphalt Roofing Systems
Asphalt roofing systems are a cost-effective and easy-to-install option for commercial buildings. They are particularly well-suited for properties with steep-sloped roofs or those requiring quick, budget-friendly solutions. Asphalt roofs provide reliable protection and last up to 20 years, making them a practical choice for smaller commercial buildings or temporary structures.
6. Modified bitumen
Modbit, made of several layers of asphalt combined with fiberglass to improve flexibility and strength, has been the most popular roofing material for the past 50 years. Known for its durability in extreme weather conditions, modified bitumen is also easy to install, resilient, and cost-effective. It is ideal for flat or low-slope commercial roofs, whose layered structure provides superior waterproofing.
7. Green Roofing Options
Green roofing offers both environmental and economic benefits. These roofs improve energy efficiency by providing natural insulation and reducing heating and cooling demands. They also mitigate heat, enhance air quality, and manage stormwater runoff.
5 Common Mistakes to Avoid When Choosing Roofing Materials
Make sure to avoid common mistakes when choosing a roofing material, including:
- Neglecting weather resistance: Overlooking local climate conditions can lead to premature roof failure. Therefore, select materials that can withstand the region’s environmental challenges.
- Prioritizing costs: Failing to consider reflective properties, insulation compatibility, or eco-friendly materials can result in higher energy bills and reduced sustainability.
- Overlooking energy efficiency and environmental impact: Failing to consider reflective properties, insulation compatibility, or eco-friendly materials reduces sustainability and increases energy costs.
- Not considering regulations: Ignoring local building codes can lead to legal issues, fines, or costly modifications.
- Not consulting professionals: Attempting to choose a roofing material without expert guidance can result in inappropriate selections that don’t meet structural or functional requirements.
Conclusion
Choosing the right roofing material for your commercial building is a complex decision that impacts the structure’s longevity, energy efficiency, and overall performance. This guide has outlined essential considerations, including climate, building design, budget, sustainability, and compliance with regulations, to help you make an informed choice.
However, selecting the right roofing material requires expertise.
Professional roofing assessments ensure that chosen materials align with the building’s structural requirements, long-term goals, and local regulations.
