A flat roof can create the need for special attention when it comes to preventing leaks and maintaining a solid fix of the flat roof repair an individual has performed. While any roof should be repaired in such a manner than it won’t leak, flat roofs do not have the run-off benefit that a sloped roof offer. The person performing flat roof repair needs to take this into account and make sure the seal is water and weatherproof.
Flat Roof Repair Tips
There are four important steps to repairing your flat roof. If you follow the steps in order and with care, you should be able fix your flat roof without problems.
Step 1 – Remove damaged tiles.
You will need to cut around the damaged area with a strong, sharp blade. Cut an area large enough to work with that encompasses the entire leak. Cut the area in a square or rectangle to make patching the area more secure.
Step 2 – Cut new tiles.
Make a template of new roof tiles to place in the space left by the old tiles. Place the old tiles on top of the new tiles to use as a template. Be sure to cut as many as you need to fill the thickness completely. This may require several tiles.
Cut one final tile an inch larger than the patch tiles.
Step 3 – Cover the hole left when the old tiles were removed.
Using a trowel, apply roofing cement to the entire surface you are going to cover with the new tiles. Be sure to extend the cement an inch or so beneath the surrounding tiles to create more of a weatherproof seal. Nail the tile down with roofing nails. Repeat this step with new roof tiles until the new patch is of the same thickness as surrounding tiles. You can simply nail the extra tiles in place without the need for cement, however.
Step 4 – Cover the patch and weatherproof
The last new tile is larger than the patched area. Nail this larger tile over the entire area, making sure that all the seams are covered. Apply a layer of roofing cement around the edges to completely waterproof the new flat roof repair. Because water will not run off the roof (there is no slope to allow for this), this technique should make sure that no water will seep beneath this final patch.
