Roofs are the most important part of any structure in terms of protecting people from sun, rain, snow and other weather phenomena. So, it becomes obvious that it’s the Roof that is exposed to the weathering phenomena facing different temperature and humidity conditions which, in-turn results in corrosion and decaying of the roofing material. The International Building Code determines that the roofs are the protectors of the building. At the same time it should also be noted that roof also happens to be the most ignored part of the structure. Lack of maintenance leads to various problems from time to time and often results in premature aging of the material requiring major maintenance or replacement of roof.
One simple solution to the roof damage problem is timely and routine inspection of roof to identify any signs of damage. Regular inspection can save a lot of hassle and money and will definitely suffice repair instead of replacement. Following are some points, which should be taken into account while inspecting the roofs:
- Leakage and Moisture:
Leakage and moisture retention often takes place due to external factors like rain, snow, hail, debris etc. Continuous exposure to weather may develop cracks and fissures in the top layer which leads to moisture seeping to the lower layers causing leaks and mold.
- Faulty Installation:
Very often the problems of roofs start right at the time of installation. Irregular gaps between pans, improper sealing of joints etc. can lead to long-term problems. Faulty installation of flashing also causes leakage. Flashing cover the edges where the roof is infiltrated to fit drainpipes, sun roof etc. if flashing is faulty then the moisture seeps in along the edges causing damage.
- Ponding:
Improper slope, accumulation of debris and leaves in the drain pipes and gutters leads to ponding of water on the roof leading to premature aging of the top layer.
- Punctures and Damages:
The top layer of the roof may be punctured due to various factors such as by hail, wind, debris, birds and animals and insects etc. The roof needs to be regularly inspected for any such damage, which may start in form of a small crack or hole but will ultimately lead to bigger problems.
- Shrinkage:
Very often the roof membrane shrinks with time and change in temperature. Shrinkage leads to cracks and blisters which may lead to problems of leakage and moisture.
- Lack of Ventilation:
When the temperature is naturally or artificially managed inside the building, the hot air rises up. Proper ventilation of roof and attic is necessary to keep the roof intact in long run. Lack of ventilation may make the whole structure weak causing problems.
There are many other possible causes creating roof related problems depending on weather and regional factors besides these common problems. One should always keep in mind that the inspection and maintenance of the roof should be done on a regular scheduled basis. A simple process of maintenance can save you fortunes in roof replacement.
