Why is the Roof Leaking

Comfort in the house, among other things, is determined by the integrity of the roofing. If the roof is leaking, wet spots, mold will form in the room, the fungus will start, and there can be no talk of comfort. What to do in this case? Changing the house is not an option. It is much easier and faster to repair the roof. But before starting work, it is necessary to determine the place and cause of the leak, select the materials, and then pay due attention to preventive measures.

Why is the roof leaking

Roofing can leak for various reasons. These are the most popular according to experts:

    • exceeding the life of the coating;
    • low-quality installation;
    • leakage where pipes, antennas, walls adjoin.

Roofing can also become unusable due to mechanical damage.

There is another classification by which the sources of roofing leaks are determined:

    • rain (formed immediately after rain);
    • snow (appear when the snow begins to melt);
    • dry (condensate);
    • flickering (appear in different places and indicate that it is necessary to change the entire roofing as a whole).

Exceeding the service life

Any roofing, even the most expensive, has a kind of warranty period. So, bitumen serves about 15 years, metal – about 30. If the roof has been used for more than 2-3 decades, it is likely that the material fell into disrepair for natural reasons. Due to constant temperature changes, precipitation, and mechanical impact (cleaning), the roof is gradually thinning. The thickness decreases by 2–3 times. In some places, small holes form, which is sometimes simply invisible to the human eye. But water easily seeps through them and causes a lot of inconvenience to homeowners.

Poor installation

Not always, but there are situations when roofing specialists work poorly. The results of this careless attitude will be visible after the first rain. Sometimes negligent masters try to save money and use an insufficient amount of sealant or insulation. Because of this, condensation forms, which appear in the form of unpleasant wet spots on the ceiling.


In places of pipe laying and adjoining walls, tightness is violated. In fact, between the roof and one of the above elements, there is a cavity inside which destructive condensate forms. Moisture accumulates, and then flows down, respectively, yellow or dark spots form on the ceiling. They spoil the general aesthetics of the room and contribute to the formation of mold, fungus, the propagation of harmful bacteria.
