Repair Flat Roof
Flat roof is also popularly known as low-slope roof, and just like any other roofing, it may need repairs. Although there are many Do-It-Yourself guides on the internet, you need to hire a roofing expert to do the job. First, the expert will observe the roof and determine whether the issues identified can be solved by repairs, or there is need of total replacement of the roofing system.
The following are the steps observed when you want to repair flat roof.
Locating leak in flat roof:
Although finding the spot of leakage in flat roof is not as complex as in shingled or steep-sloped roof, the leaks can be quite deceiving. The point where the water gets in to the interior space may not be the exact point of the leakage. This is because water which penetrates to the roofing membrane may travel some distance before finding seam within the sheathing or sub-roofing where it seeps inside.
Note that, up there in the roof there may be darkness so the roofers need to use lighting. Also, heights and ladders must be used but you must be very careful to avoid falls. During winter, the roof may be icy and slippery. Simply put, a lot of caution is required to ensure no injuries happen in the course of repairing the roof.
The process of repairing:
Most roofers give a warranty on flat roofs, ranging between 5 and 20 years. When the flat roof develops issues when it is still covered by the warranty, you should get in touch with the contractor which installed it, and the necessary repairs will be undertaken. There are some manufacturers and installers who issue warranty prorated for the roof’s age, and in that case, the professional repair will help you save money. If the warranty is over, then you need to think of how you can undertake the repairs at your cost, and you will have to hire contractor to do the job.
The tools required:
The successful repair of the flat roof, various tools are used and they include membrane cleaner, hand roller tool, seams scrubbing tool, rubber glue, and roofing tape. Also required is ladder and roofing ladder stabilizer, paint brush (for spreading the glue) and warm water. Other tools may also be required depending on the specific roofing system in place, and also the nature of leakage that needs to be repaired. These tools include caulk gin, utility knife, putty brush or knife, and tube of roofing cement or sealant.
For small punctures and holes, you can repair by simple application of rubber sealant from the tube. In tar and gravel roofs, you can repair by the simple application of tar to the damaged area, by use of caulk gun then smoothing with brush or putty knife. Membrane blisters can be solved by the simple puncturing of the blister then applying the right sealant. For the larger tears and rips in the roofing structure, the damaged section should be removed and then a printer and cleaner should be applied in the right way.
Weighing repairing versus replacement costs:
Some slow roofing contractors will make you believe that repairing a roof is worthless venture, and that the only viable option is replacing. This is not always wrong, as an expert should help you weigh how much it will cost to repair and how much it will cost to replace. Also important is an evaluation of how long the roof will last after the repairs. Note that replacement is only recommended where the costs of repair are too high, or where the roof is in such a state where it needs very frequent repairs which will be costly in in the long run.
