The roofing system of a house shouldn’t be ignored by contractors since a bad roof can easily leak much to the disguise of the home owner. Good roofing materials and quality workmanship will ensure the roof comes out great. However, with time, the roof will age and may start to leak as a result hence the need of roof repair. The first signs of a leak will be signs of dampness on the ceiling or actual dripping of water.
As soon as there is a sign of a leakage, you need to find the exact location of the leak and chances are that it may not be directly above the dump section of the ceiling. Ensure that you establish the overall condition of the flat roof to ascertain if the whole roof need replacement or the damage is small enough to be repaired. Remember it is not worth it to try to repair a roof whose lifespan is on the brink of conclusion.
The damages on the roof will include: cracks and chips, blisters, splits and tears, lifting overlaps and flashings.
Roofline rubber roofs EPDM has proved to be very reliable since it is leak proof if properly installed, can tolerate temperature variations and sunlight.
1. Blisters in the felt•
Clean the blister carefully to get rid of any chippings, mould or dirt.
• Use a sharp craft knife to make a cut through the top layer.
• Peel back the parts and dry the underneath using a heat gun.
• Apply EPDM liquid rubber to the exposed surface and fold back the parts.
You should ensure that the cut area overlaps the blister by 2 inches.
2. Splits ant tears•
Lift the split or tear without destroying the felt further and clean the space under it as well as the area around it.
• Fill the space under the split or tear with liquid EPDM rubber.
• Press it down and fill other voids with the liquid EPDM rubber.
• Cut a piece of new felt to use as a patch. Remember to give a 2 inches allowance beyond the cut.
• Apply the adhesive over the repair to fit the piece.
• Place the patch into place and seal the edges well.
3. Lifting overlaps•
Lift the overlap, clean it and leave it to thoroughly dry.
• Fill the space under the overlap with liquid EPDM rubber and press it down gently.
• Weigh the seam down as it dries to prevent the overlap from lifting as the adhesive dries
Clean off the surface
• Cut the EPDM rubber tape and apply it on the area.
• Smooth it down the clean surface ensuring that the edges are well sealed and the tape is well stretched with no creases.
• Always start with the lowest trip and overlap upwards. Make sure the overlaps are well sealed at the ends
As seen some processes require liquid EPDM rubber while others will need the tape version of EPDM rubber. Ensure you use the correct version where necessary.
