Since most flat roof problems arise from the inability to find the exact location of the minor defect and to repair it at an early stage, roof inspections must be performed on a regular basis. It is recommended that you do this two times a year, in the spring and autumn (fall), and to record the condition and any changes observed, for you to get the better understanding on how does your roof changes over time. In that way, you can prevent any defect no matter how minor they can be.
These can be wrinkles, bubbles, drainage problems, torn material, cracks, holes, openings or waste and shocks that sometimes accumulate even on the roof. It is important to check the roof during light and heavy rain to determine if and to what extent and how long the water is retained on the roof. During the check, it is necessary to look at the interior walls and ceilings. Inspection of flat roofs in developed countries is done even with infrared cameras, night shots that accurately show damp places invisible to the naked eye, which are cooler than the rest of the roof.
If you find a problem
If the problem is diagnosed in time, it can save you significant money, before greater intervention becomes necessary. The openings can be filled, the missing material is added, and if there is a problem with water retention, the possible solution is to increase the inclination of a flat roof. Water retention was most often solved earlier by placing layers and paper and aggregates on existing layers, while today bituminous coatings can be used for such minor repairs.
It is also very important to regularly clean the vegetation that appears on the surface itself, as the plants create and expand cracks and weak spots, and retaining water increases the moisture and danger of leakage. A special case of a favorable solution for a flat roof with the use of vegetation are the roof gardens which will be more words in other articles.
When, after a predetermined amount of time which can eventually be extended to a certain extent.
The roof expires, the anticipated lifetime expires, and besides the alignment, there are leaks, instead of adding a new layer, it is recommended to replace the whole flat roof, possibly with some of the more modern solutions.
