Concrete roof repair in Jamaica and the rest of the world is often necessary because concrete is susceptible to scaling, cracking, crazing, spalling, and a host of other issues with regular wear and tear, heat and water. In most cases, minor, timely repairs and regular maintenance will ensure that there is no structural damage. The root problem when using concrete as a roofing material is that concrete is porous and retains moisture and is prone to water leaks

Sanded Waterproofing Roof Membranes
The proper design of falls in a flat roof is an essential consideration in the overall drainage of the roof. Falls create flow paths to direct the drainage of rain-water away from the roof to suitable discharge points. To be effective, it is essential to clear surface water as rapidly as possible from the flat roof to avoid ponding or stagnation of water on the roof itself.
Waterponding on a flat roof is a prime cause of deterioration because variations in temperature between wet and dry areas of the roof can cause differential thermal movement. Together with the accumulation of acids left by evaporating rain, this would cause a breakdown on the roof surface. In general, a minimum fall of 1 in 80 will help to prevent ponding of water.
One type of pre-formed membranes is the polymer-modified bitumen membranes and they are applied by heat or attached with an adhesive. These blended or ‘modified’ asphaltic product are bonded to a high strength fabric of polyester or fiberglass and produced into rolls. They have elongation and recovery properties which make them suitable to protect against stresses created by wind, temperature fluctuation and normal structural expansion and contraction of the building. Some of these products are also modified to increase their resistance to fire, thus increasing their fire-rating. Styrene-butadiene-styrene (SBS) rolls are modified with ‘rubbers’ and compatible with petroleum products. Atactic Polypropylene Polymer (APP) rolls are modified with ‘plasticizers’ and not compatible with all petroleum-based products, grease and oils.
Summary of Slab Roof Repairs in Jamaica
Proper design of falls in reinforced concrete flat roofs is most important in creating flow paths to suitable discharge points. For a roof to be effective, surface water should be discharged quickly without ponding or stagnation. Next, it is important to select the appropriate waterproofing membrane. As the roof is constantly exposed to direct sunlight and rain, it is likely to experience tremendous thermal stresses that will affect its physical properties and performance. Pre-formed waterproofing membranes generally will perform better than liquid applied membrane as it can bridge over cracks and gaps better. Also, as they are more resistant to indentations caused by traffic, they are suited for large flat roofs areas exposed to foot traffic
