How to repair a leaking felt roof.

We had a problem with our shed workshop flat felt roof leaking and needed a quick repair. The nail will provide a path for the water. Insert a nail in the hole where water is leaking through the roof. Step 2 place a bucket underneath the nail to catch the water as it runs down the nail.

Pour some water on the felt roof to see how the water runs into the gaps. Firstly measure from the outside wall of the room along the ceiling to the damp spot dripping area. Cut a piece of new felt to use as a patch big enough to give above a 50mm 2 inch overlap beyond the repaired blister. Small nail holes left behind from old vents satellite dish brackets or anything previously attached to the roof can allow water to enter and cause damage for years before leaking is noticed.

To fix a felt flat roof leak first find out where the water is working it s way through the felt. Ensure the nails that. Apply some bitumen adhesive over the repair and beyond to suit the patch and apply it. Patch the nail or screw holes by slipping a piece of roof flashing underneath the shingle.

Apply some bitumen adhesive to the exposed surface and fold back the segments. Instead of replacing the felt roof we decided to use a product call. Press down the top layer into the adhesive. After setting the patch in place press it lightly and drive roofing nails around its perimeter.

This will usually be a crack in the felt or where the felt has peeled away from the roof.
