Installation of EPDM Roofing

The installation process for EPDM roofing involves careful preparation and specific techniques to ensure a durable and effective roof. Proper surface preparation, installation techniques, and attention to seaming and detail work are crucial for achieving the best results.

Surface Preparation

Before installing EPDM roofing, the surface must be prepared thoroughly. Start by removing any old roofing material and fixing any damaged areas of the roof deck. This may involve using a toothed roofing spade for removal and patching larger holes with plywood.

Next, clean the roof deck. This involves sweeping away debris, dirt, and dust to ensure proper adhesive bonding. The surface should be dry and smooth. If using insulation boards, secure them properly and make sure they are even and stable.

A stable substrate is essential. If working with an existing structure, ensure it can support the new roofing system without sagging. Lastly, allow any potential moisture to dry out completely to avoid future problems.

Installation Techniques

EPDM installation requires specific methods for best results. Begin by measuring the roof area to cut the EPDM membrane to the correct size. It’s critical to unfold and lay the membrane on the roof, allowing it to relax for a moment.

After placing the membrane, use a water-based adhesive. Apply it in sections and lay down segments of the EPDM on the wet adhesive before adding more. This technique helps secure the membrane firmly.

Brush the freshly laid EPDM with a broom to enhance contact with the adhesive. Ensure that the edges of the membrane are properly aligned and avoid wrinkles during this process. Folding back half of the membrane aids in applying adhesive evenly.

Seaming and Detail Work

Seaming is essential for an effective EPDM roofing system. Once the main membrane is laid, it is important to ensure that all seams are tight and well secured. Overlap seams by at least 3 inches and use a seam tape that is compatible with EPDM for the highest integrity.

Adhesive should be applied to both surfaces of the seam before pressing them together. Ensure a smooth connection to prevent leaks. For areas around vents, skylights, and edges, special attention is needed. Use flashing and trim pieces as required to seal these details securely.

Regular checks on the seams post-installation will help maintain the roof’s integrity over time and prolong its lifespan.

Types of EPDM Roofing Systems

EPDM roofing systems come in different varieties, each designed for specific installation methods and conditions. Understanding these types can help in making the right choice for a building’s roofing needs.

Ballasted EPDM Systems

Ballasted EPDM systems use weight to hold the roofing membrane in place. Typically, large stones or concrete blocks are distributed over the surface.

This method does not require any adhesives, which can reduce installation time. It offers good resistance to wind uplift and is ideal for flat roofs.

However, proper drainage is essential to prevent water accumulation. The thickness of the membrane often ranges from 45 Mil to 60 Mil, impacting its lifespan and performance. This type is usually cost-effective, making it popular for commercial buildings.

Mechanically Attached Systems

Mechanically attached EPDM systems involve fastening the membrane to the roof deck using screws and plates. This method allows for a tighter fit and better stability, especially in windy areas.
