Stick roof foil - easy and fast

Roof foil can also serve as an alternative to bituminous membranes - the newly developed EPDM foils for roofing offer a number of significant advantages over the traditional, complex bitumen cover. How to properly transfer them, read in this post.

Modern plastics have advantages

On the one hand, bituminous roof coverings must be laid in two layers; in addition, the seams must still be welded in order to actually ensure tightness of the roof.

The roles have to be laboriously heaved individually on the roof, and without a helper you usually only get along, if you are reasonably adept and experienced.

EPDM film offers a few major advantages here: it can be cut to the approximate size on the ground and is usually brought to the roof in one piece and then merely glued.

At the same time it is more resistant and more durable than bituminous coverings and just as rainproof.

What is there to know about EPDM film?

  • It is durable and extremely durable - a lifetime up to 50 years and above is realistic
  • The abbreviation EPDM stands for Ethylene Polypropylene Diene Monomer and is a special plastic
  • After bonding, EPDM film keeps completely tight but can occasionally wrinkle, which is harmless

This is how the EPDM film is glued to the roof

  • EPDM foil
  • suitable adhesive (there are different brands with their own processing instructions)
  • scissors
  • Roller for the glue application
  • broom

1. Preparation of the roof

Before gluing, the roof must be clean, clean and dry. There must be no leftovers of old bituminous surface.

2. Cut the film roughly and let it "snap" on the roof

Even before transport to the roof, the foil can be cut with the scissors to the rough dimensions - but you should also factor in about 15 cm of protrusion on the sides.

After that, the foil laid on the roof has to rest for half an hour, so that it can contract again evenly.

3. Bond the foil

Knock back about half of the film and coat the substrate thinly with glue. The EPDM film is then merely gently pressed into the adhesive and the wrinkles and blisters are smoothed with the brush in the direction of the edge of the roof.

Thereafter, the second half is knocked back and also glued in the same way.

Tips & Tricks

To get a nicer roof finish, you can also attach strips or profiles to the edge of the roof.
