How To Replace A Damaged Flat Roof

Roofs come in many designs and depend mainly on your preferences. The most commonly installed roof style is the flat one because it is durable and practical. Even if you have no experience with roofs, flat roofs are the simplest roofs that you can repair yourself. However, if you are in doubt about your expertise, turn to trusted roofing replacement companies to get your job done.

  • EPDM rubber
  • Strong glue
  • protective gear
Remove any roof debris by poking it with a spade

Roofs are made of felts, fabrics and mats, which are known as layers. Wear safety glasses, gloves, boots and long pants. If you’re on firm ground, hold your spade at about a 35-degree angle and launch from one spot. Use a small, rounded spade to separate the damaged layers of your roof and set them aside for proper disposal. Remove the felt, take off the gutters and siding so you can effectively remove the roof underneath.

Peel off the perimeter filled with mortar

Take the damaged pieces of mortar and slowly peel them off by wiggling them. If they are not yet loose, place a spade under the debris and gradually remove them. If you can’t break the area flush with the wall, use a screwdriver on the wall and hit the handle with a hammer to eject the dry grout.

Scrape off the remaining pieces of mortar.

Use a hammer and a pad to scrape off the pieces of concrete that are still adhering to the masonry. Add a space between your roof and the felt and slowly apply pressure upwards, removing the roof edges. Stand in a permanent location near the front roof. Slide a stripping knife across the front of your roof to remove any remaining felt.

If you have wood fillets on your roof, be sure to take them off before replacing them with a new roof.

Attaching an EPDM roof

The following steps will guide you in attaching your EPDM membrane.

Measure the size of your roof

Use a tape measure to determine the length and width of your roof. Add a few inches to your measurements for some overlap. Make your measurements available to your EPDM supplier and buy a thicker membrane for a long life. Thoroughly clean the surface on which you are laying the EPDM membrane to ensure good adhesion.

Opening of the EPDM

Place the folded membrane in the middle of your roof. Fold the top fold so that it is parallel to the edge of the roof.

Expansion of the EPDM membrane

Completely distribute the membrane on your roof while aligning it well around the edges. Let the extra inches of your membrane hang from the edge of the roof. Let the membrane sit for about 40 minutes so that it fits properly on the roof.

The next step is to pull back the membrane from the left and fold it to the right edge of the roof. Make sure that two layers cover the right side of your roof.

Apply glue

It is recommended that you use a water-based adhesive. Using a glue roller, apply the adhesive horizontally from the base of the EPDM. Make sure you apply the adhesive to prevent air pockets from forming. Completely cover the left half of the roof with glue, then move to the right side.

Attaching the membrane to the roof

After applying the water-based adhesive, push the membrane into place. Press evenly on the membrane with a broom to remove air spaces. Wipe the broom from one corner of the roof to the other until the membrane completely adheres. The unattached flaps of the membrane should be glued to the sides of the roof.

Working from the roof can be extremely dangerous. Make sure you stand on firm ground while working on the roof to avoid accidents.
