EPDM Roofing 101: An Overview Of Materials
In the world of commercial roofing, choosing the right material is crucial for ensuring:
- Longevity
- Durability
- Cost-effectiveness
One of the most popular options in today’s market is EPDM (Ethylene Propylene Diene Monomer) roofing. This guide will provide a thorough overview of EPDM roofing, explaining why it’s a top choice for property managers and commercial building owners.
What is EPDM Roofing?
EPDM is a type of synthetic rubber roofing membrane widely used in low-slope buildings. Its formulation includes ethylene and propylene derived from oil and natural gas, making it highly resilient and flexible. Available in both black and white, EPDM membranes come in a variety of widths, typically ranging from 7.5 to 50 feet, and are available in thicknesses of 45 and 60 mils.
Noteworthy Features
- Durability: EPDM roofing is renowned for its long-lasting performance, often exceeding 20 years with proper maintenance.
- Flexibility: The membrane remains flexible in varying temperatures, making it less prone to cracking in cold weather.
- UV Resistance: EPDM provides excellent resistance to ultraviolet (UV) rays, preventing degradation from sun exposure.
- Eco-Friendly: EPDM is an environmentally friendly option as it can be recycled and has a low environmental impact during its production.
Benefits of EPDM Roofing
There are lots of reasons to choose EPDM, including:
Longevity and Durability
EPDM’s robust composition ensures that it can withstand extreme weather conditions, including heavy rain, snow, and high winds. Its durability means fewer repairs and replacements, saving property managers significant costs over time.
Cost-Effectiveness
One of the major advantages of EPDM roofing is its cost-effectiveness. The initial installation costs are relatively low compared to other roofing materials. Additionally, its long lifespan and minimal maintenance requirements make it an economical choice for commercial buildings.
Easy Installation
EPDM roofing can be installed using several methods, including ballasted, fully adhered, and mechanically attached systems, each offering different benefits. The installation process is straightforward, reducing labor costs and installation time.
Energy Efficiency
The reflective properties of white EPDM help in reducing cooling costs by reflecting sunlight and heat away from the building. This is particularly beneficial for commercial buildings located in hot climates.
Environmental Impact
EPDM is considered a “green” roofing option due to its ability to be recycled at the end of its life cycle. It also has a lower environmental impact during production compared to other roofing materials, making it a sustainable choice.
EPDM Roofing Installation Methods
Choosing the right installation method is crucial for maximizing the benefits of EPDM roofing. Here are the three primary methods:
Ballasted System
In a ballasted system, the EPDM membrane is loosely laid over the roof deck and held in place by a ballast, usually consisting of smooth, river-washed stones or pavers. This method is quick and cost-effective but requires a sturdy roof structure to support the additional weight.
Fully Adhered System
In a fully adhered system, the EPDM membrane is glued directly to the roof substrate using a special adhesive. This method offers superior wind uplift resistance and is ideal for roofs with unusual shapes or numerous penetrations.
Mechanically Attached System
In a mechanically attached system, the EPDM membrane is fastened to the roof deck using mechanical fasteners. This method is commonly used for large commercial roofs as it provides good wind uplift resistance without the need for ballast.
Maintenance and Repairs
One of the key benefits of EPDM roofing is its low maintenance requirements. However, regular inspections and prompt repairs are essential for ensuring its longevity.
- Regular Inspections: Conduct bi-annual inspections to identify any potential issues, such as punctures, tears, or seam separations. Pay particular attention to areas around roof penetrations, such as vents and drains, as these are common points of failure.
- Common Repairs: EPDM repairs are relatively straightforward and can often be performed by maintenance staff. For minor punctures or tears, repair kits are available that include patches and adhesives. For more extensive damage, it’s advisable to consult a professional roofing contractor.
- Preventative Maintenance: Implementing a preventative maintenance plan can extend the life of your EPDM roof. This includes keeping the roof clean and free of debris, maintaining drainage systems, and ensuring that rooftop equipment is properly secured and not causing damage to the membrane.
Choosing a Contractor: 3 Main Tips
Selecting a qualified and experienced roofing contractor is crucial for the successful installation of an EPDM roofing system. Here are some tips for choosing the right contractor:
1) Experience and Reputation
Look for contractors with extensive experience in installing EPDM roofing systems. Check online reviews and ask for references from previous clients to gauge their reputation.
2) Certifications and Training
Ensure that the contractor is certified by the EPDM manufacturer. This certification indicates that the contractor has undergone specialized training and adheres to the manufacturer’s installation guidelines.
3) Comprehensive Quotes
Obtain detailed quotes from multiple contractors. The quote should include a breakdown of all costs, including materials, labor, and any additional services. Be wary of quotes that seem unusually low, as they may indicate subpar materials or workmanship.
