EPDM rubber roofing has been the number one preference for commercial buildings for decades because of its flexibility, durability, and affordability. However, to ensure your roof performs well and has a long lifespan, it needs to be installed correctly. But how long does it take to properly install an EPDM roof?
The short answer is: between a few days and a couple of weeks. However, the duration of EPDM roof installation varies based on several factors, such as roof size, weather, and the installation technique employed. Larger roofs take longer to complete, and harsh weather conditions can slow down work.
What is EPDM Roofing?
EPDM is an abbreviation for Ethylene Propylene Diene Monomer, a synthetic rubber roof membrane. While most flat roofs do not last more than 20 years, EPDM is a budget-friendly, long-lasting membrane with various installation processes to meet different project demands. EPDM roofs last up to 30 years and are resistant to extreme weather conditions, such as heat, UV rays, hail, snow, and fire. These rubber roofing membranes also come in black and white, with varying energy-efficiency benefits depending on color selection. The black membrane traps heat and keeps a building warm during winter, while the white-coated ones reflect heat and keep the building cool during summer.
How Long Does EPDM Roofing Installation Take?
It typically takes between a few days and a couple of weeks. On a flat roof, the installation may take only 2-3 days. For simple, commercial buildings, a single-layer EPDM installation can take a week. However, for more complex roofs (with steep slopes or designs), installation can take a longer time. In some cases, even a month. The size of the roof and the complexity of the task will also contribute to its overall installation time.
Factors That Affect EPDM Roofing Installation Time
The following factors can affect the time it takes to install an EPDM roof.
1. Roof Size and Complexity
Roof size and complexity have a big effect on installation time. A small, uncomplicated flat roof with little in the way can be installed in a day or two. Yet, a large commercial roof with features like vents, HVAC units, or skylights takes extra time for careful cutting and sealing. The more complex the arrangement, the more time it will take to install.
2. Weather Conditions
EPDM installation is very weather-sensitive. Optimal temperatures are between 40°F and 85°F to facilitate good adhesion and sealing. Low temperatures stiffen the membrane, making it more difficult to handle, and high temperatures influence adhesive curing times. Rain or excessive humidity can also impact installation, as water prevents adhesives from sticking well, resulting in leaks and weak points.
3. Surface Preparation Requirements
Before the installation, the old roof surface has to be properly prepared. If the roof contains old or deteriorated material that needs to be removed, this contributes to additional time in the project. Moreover, repairs, insulation fitting, or adjustments to the substrate can prolong the duration. A clean, smooth, and dry surface is vital for guaranteeing a trouble-free EPDM application and durability in the long run.
4. Installation Method Chosen
EPDM roofs are installed in three primary ways: fully adhered, mechanically fastened, or ballasted. Fully adhered, where adhesive is applied to the entire membrane, takes longer than mechanical fastening, where the membrane is fastened with fasteners and plates. Ballasted installation, where the membrane is weighed down with gravel or pavers, is typically the fastest overall, but it still requires time for placing and adjusting the ballast materials.
5. Contractor Experience and Crew Size
The skill level of the roofing contractors and the number of people working on the job can largely influence installation time. A well-trained team with years of experience can do the job quickly and correctly. A big team can also speed up the process by working on various things at the same time, for example, installing insulation, fastening the membrane, and closing seams. Having a professional roofing contractor guarantees high-quality workmanship and reduces installation delays.
Tips to Ensure EPDM Roof Longevity
Proper maintenance is needed to ensure your EPDM roof will fulfill its entire lifespan. Consistent maintenance avoids expensive repairs and prolongs the lifespan of the roofing system. Below are some key maintenance tips:
- Inspect Regularly: Inspect your roof regularly, particularly after harsh weather, to check for damage, cracks, or loose seams.
- Keep the Roof Clean: Clear leaves, dirt accumulation, and debris to avoid drainage problems and water clogging.
- Inspect for Ponding Water: Excess water can cause the membrane to deteriorate over time, so ensure adequate drainage to prevent damage.
- Fix Minor Problems Immediately: To avoid further damage, fix minor tears or leaks promptly with proper EPDM repair products.
- Don’t Use Harsh Chemicals: Clean with EPDM-friendly cleaning agents to prevent surface damage to the membrane or shortening its lifespan.
By adopting these maintenance routines, you can ensure maximum performance and lifespan of your EPDM roof and prevent unnecessary repairs.
Conclusion
The duration of EPDM roofing installation varies depending on the roof size, weather, and installation method. It typically takes between a few days and a couple of weeks. However, bigger roofs take longer, and poor weather conditions can delay the process. The installation type, fully adhered, mechanically fastened, or ballasted, also influences the duration. Installation must be done properly to guarantee durability and long-term performance. Hiring a professional roofing installer is the best option to achieve optimal results.
