EPDM Installation Service
Our expert team handles complete EPDM membrane installations for commercial and residential buildings across Washington DC. We utilize advanced single-ply roofing techniques to ensure proper membrane placement and adherence.
The installation process begins with precise measurements and material preparation. We use high-grade EPDM sheets sized specifically for your roof's dimensions.
Our installation methods include both fully-adhered and mechanically-fastened systems, depending on your building's requirements. We apply commercial-grade bonding adhesives uniformly to achieve maximum surface contact.
Surface Preparation and Repair
Proper surface preparation forms the foundation of a lasting EPDM roof. We thoroughly clean and inspect the existing roof substrate, removing all debris and addressing structural issues.
Our team repairs damaged decking, fills gaps, and levels uneven surfaces. We install new insulation boards where needed to create an optimal base for the EPDM membrane.

The substrate receives a primer coating to enhance adhesion. We ensure all surfaces are completely dry and clean before membrane application.
Seam Sealing and Flashing Application
Secure seams and properly installed flashings are crucial for waterproof protection. We use EPDM seam tape and specialized primers to create watertight bonds between membrane sections.
Our technicians install reinforced perimeter fastening strips and terminate bars for enhanced edge security. Custom-cut flashings protect all roof penetrations, including vents, pipes, and HVAC units.

Each seam undergoes thorough inspection and testing to verify proper adhesion. We apply additional sealant at critical junctions for extra protection.
Regular Inspections and Maintenance
We provide scheduled maintenance services to protect your EPDM roof investment. Our inspection program includes quarterly visits to check seams, flashings, and drainage systems.
Professional cleaning removes debris and prevents water pooling. We promptly repair any damage to prevent small issues from becoming major problems.

Our maintenance team documents all findings and repairs, creating a detailed service history for your roof system.
EPDM Roof Installation Methods
Professional EPDM roof installation requires specific techniques and materials to ensure optimal performance and longevity. Each method offers distinct advantages for different building requirements and environmental conditions.
Fully Adhered EPDM Roofing
We apply bonding adhesive to both the substrate and the EPDM membrane using specialized rollers for complete coverage. This method creates a strong, continuous bond across the entire roof surface.

The membrane attaches directly to the insulation or roof deck, providing excellent wind resistance and a sleek appearance.
Our team pays special attention to seam preparation, using primer and seam tape to ensure watertight connections. This technique works exceptionally well for low-slope commercial buildings in Washington DC's variable climate.
Mechanically Fastened EPDM Systems
This system uses metal plates and screws to secure the roofing membrane to the deck. We place fasteners along the seams of the membrane at specified intervals.
The method offers quick installation and reduces adhesive costs while maintaining strong wind uplift resistance. It's particularly effective for large commercial roofs.
Our technicians carefully calculate fastener patterns based on building height and local wind zone requirements.
Ballasted EPDM Roofing Technique
This method involves loose-laying the EPDM membrane and securing it with stone ballast or pavers. We typically use smooth river rock at 10-12 pounds per square foot.
The weight of the ballast holds the membrane in place without penetrating the rubber material. This approach offers excellent insulation properties and UV protection.
We recommend this system for structures with adequate load-bearing capacity and minimal roof slope.
EPDM Roofing with Drip Batten Edge
We install metal drip battens around the roof perimeter to create a secure edge termination. This method prevents water infiltration at the roof edges.

The batten system includes a continuous cleat that anchors the membrane firmly. We seal all terminations with water block sealant for additional protection.
This edge detail works particularly well with fully adhered systems and provides enhanced wind uplift resistance in Washington DC's urban environment.

FAQs
TPO roofing installations come with many common questions from our customers. We've gathered the most important information about costs, durability, brands, and maintenance to help you make informed decisions.
What are the factors influencing the cost of a TPO roof installation?
Several key elements affect TPO roofing costs. The size of your roof is the primary factor, as larger areas require more materials and labor.
The thickness of the TPO membrane impacts pricing significantly. We offer options ranging from 45 mil to 80 mil thickness, with thicker membranes costing more but providing enhanced durability.
Your roof's complexity matters too. Buildings with multiple penetrations, HVAC units, or unusual shapes require more detail work and flashing.
Accessibility affects labor costs. If your roof is difficult to reach or requires special equipment, this will increase the installation price.
How long does a TPO roof typically last under normal weather conditions?
TPO roofs installed by Washington DC Roofing Company typically last 20-30 years with proper maintenance. This lifespan depends on several factors including membrane thickness and local climate conditions.
The quality of installation significantly impacts longevity. Our certified installation team ensures all seams are properly welded and details are correctly finished.
Modern TPO formulations have improved UV and heat resistance compared to earlier generations. This enhancement helps maintain reflectivity and structural integrity over time.
Regular inspections can help identify and address small issues before they compromise the roof's lifespan.
Which TPO roofing brand shows the highest performance and reliability?
We primarily install GAF and Firestone TPO systems due to their consistent performance records and extensive warranties. These manufacturers have refined their formulations over decades.
GAF EverGuard TPO offers excellent heat and UV resistance with their advanced material science. Their products perform exceptionally well in Washington DC's varying climate conditions.
Firestone UltraPly TPO provides superior puncture resistance and flexibility, maintaining performance through seasonal temperature changes. Their seam strength is among the industry's best.
Both brands offer comprehensive warranty options that can extend up to 30 years when installed by certified contractors like us.
Are there any notable drawbacks when using TPO roofing for commercial buildings?
Installation quality is critical with TPO systems. Poorly welded seams can lead to leaks and premature failure, which is why we invest in ongoing training for our installation teams.
Some older TPO formulations had issues with premature aging and cracking. Today's improved materials have largely resolved these concerns, but choosing a quality manufacturer remains important.
TPO can be punctured by sharp objects, making regular roof inspections necessary. We recommend establishing maintenance protocols after installation.
While highly energy efficient, TPO's initial cost may be higher than some traditional roofing systems, though this is typically offset by energy savings over time.
Can a TPO roof be installed over an existing roofing system, and what are the considerations?
Yes, in many cases we can install TPO over existing roofing, potentially saving on removal costs and reducing landfill waste. This approach is called a "recover" installation.
The existing roof must be structurally sound and relatively dry. We conduct moisture scanning to detect any trapped water that could compromise the new system.
Building codes typically limit commercial buildings to two roof layers. We'll verify local regulations and assess your current roofing situation during consultation.
Proper preparation may include adding recovery board insulation to create a smooth, compatible surface for the new TPO membrane attachment.
