How to Install an EPDM Rubber Roof on a Shed

A Step-by-Step Guide from Puffin Sheds Swindon

At Puffin Sheds, our EPDM rubber roofs are supplied as a complete kit, including the correct adhesive and roller for easy installation. Must be purchased with a shed.

What You’ll Need

• EPDM rubber roofing sheet
• Adhesive (supplied)
• Roller (supplied)
• Soft brush or hand roller
• Clout nails
• Fascia boards / edge trims

Step 1: Prepare the Roof

Brush the roof surface thoroughly to ensure it is clean, dry, and dust-free. Remove all dirt and debris so the adhesive bonds properly.

Step 2: Position the EPDM Rubber

Lay the EPDM rubber loosely over the roof and allow it to settle naturally.
Ensure it overhangs evenly on all four sides.
Do not pull it tight — the rubber should lie flat on its own.

Step 3: Bond the First Half

Weigh down one half of the rubber sheet.
Peel back the other half and apply adhesive evenly across the exposed wooden roof using the roller. Roll the EPDM back into place slowly and use a soft brush to remove any trapped air until the surface is completely flat.

Step 4: Bond the Second Half

Repeat the same process on the remaining half of the roof, ensuring full contact and a smooth finish.

Step 5: Secure the Edges

Fold the rubber over the roof edges and secure it with clout nails beneath the trim line.
Refit the fascia boards or edge trims to complete the installation.

Installing Two EPDM Sheets (Larger Roofs)

If your shed requires two EPDM sheets, join them using EPDM double-sided joining tape before bonding them to the roof.
Ensure the joint is fully sealed and smooth before continuing with the adhesive process.
