The roof system is one of the most important assemblies in a commercial and residential building. Every year commercial maintenance managers and home owners would spend 50% of their maintenance budget on the roof. One of the best ways to protect this important building component is by waterproofing.
Building and home owners would spend abut 5 to 10% of their construction cost on roofing assemblies. Houses located in areas with heavier rain downfall usually have slating roofs, so that the water would slide sideways, away from the surface. However, there are houses and building that have flat roof systems which could cause water to stay on the room for sometime.
It is also common to find commercial and residential buildings with concrete roof systems. Concrete roofing systems are not actually water proof. Concrete roof like those made of tiles or shingle, could easily get weak and crack when consistently exposed to water and moisture. They could also develop serious cases of molds and mildew which could endanger the health of those living in the building.
To determine the condition of your roof, there should be maintenance program that would include inspection and regular maintenance task. For commercial buildings, a detailed survey or inspection could be done to check all the components of the roofing system. Defects would be identified and repairs would be recommended. Ideally, a roof should be inspected twice a year.
If you have concrete roof structures, make sure to use waterproofing materials for the roof. The roof should be regularly checked for broken or missing tiles and shingles or clogged gutters. There are specialized rubber and plastic coats which could be applied to extend concrete life. This coat or membrane could protect the roof; however, it is important to seal all cracks before applying the membrane.
There are some spray-on waterproofing products which could also seal cracks and leaks. There are also some products which are applied to the shingles, just like paint. There are membranes which are applied under the shingles and tiles, creating a moisture barrier.
Concrete roofs should also have proper drainage. Some homeowners would use damp proofing since it costs less, however, waterproofing proved to be more effective in keeping the water away. In severe cases, tiling would be removed and would undergo a special waterproofing treatment. This could be very costly.

Just verify with friends or relatives, who have used the services of the contractor before, if they were able to provide good service. You could also ask them for recommendations.
