Flat Roof Repair Tips

Introduction:

Flat roofs are very common in industrial construction as well as home construction. Flat roofs are highly vulnerable to damages and leaks from standing water and ice. Ice and water does not run off of flat roofs as it does on pitched roofs. The water accumulates on its surface which leads to water leaks. Debris and other materials, such as leaves and twigs, also collect on flat roofs. In addition, harsh weather conditions and the heat from the hot sun can further wear it out.

By taking a few precautions and performing routine maintenance a flat roof can last just as long as a pitched roof before it has to be replaced. Here are some DIY flat roof repair tips to make a flat roofs last longer and avoid roof leaks.

·       If you have water leaks, look for their source and repair them immediately. Keep in mind that water often puddles and travels to different areas of the roof making it difficult to locate the leak. Searching for the leak when the roof is dry makes this task easier.

·       Check for cracks in and around flashings. Flashing is installed as a barrier between the roof and the chimney or on the roof's edge. Make sure there are no cracks or little openings in the flashing.

·       Clean the roof often. Sweep off gravel and debris that have accumulated. A clear view of your roof will make it is easier to see possible damages. When your flat roof's top layer is separated from the layer beneath it a blister or crack may form that needs immediate roofing repair. You can remedy this by using a sharp knife to slice through the middle of the blister. Carefully cut the top layer to avoid damaging the felt beneath.

·       Remove any water inside the blister. Open the edges of the damaged area and let it thoroughly dry. Once the area is dried, pour roof cement on the bottom edges of any loose felt and press down the blisters' edges firmly. Next, nail the sides of the blister and spread another coat of roof cement on the repaired area. Make sure nail heads are also covered with cement.

Remember to use asphalt lightweight cement or acrylic based products when filling the puddle areas of a damaged roof. This can prevent future roofing problems. Fiberglass seam tapes are also good reinforcement for the edges of a patch. When the roof cement has dried, the fiberglass tape prevents cracking on the edges. If you are repairing your roof during cold weather, a propane torch with a flame spreader nozzle will help dry out cement and felt. However, this must be done cautiously since roofing felt and tar are flammable.
