Repair Leaky Slab Roofs In Jamaica

slab roof repairs in Jamaica

A leaky roof is a stressful situation and one that can turn into a watery nightmare and costly repair if not addressed quickly. However, sometimes a homeowner isn’t aware there’s a problem until telltale signs appear which is usually after a few days of heavy rainfall. No one in Jamaica wants to see water leaking through their concrete slab roof. Even with regular roof maintenance, harsh weather can roll through, and you can find a puddle on your floor or stain marks running down your walls.

The most common complaint with regard to both concrete tile and flat concrete roofing in Jamaica is water leaks. When there are leaks in a flat concrete roof, the fast fix is usually to apply some kind of sealant or waterproof cement at the site of the leak. Most of the times, cracks can be filled with similar caulking materials to prevent further damage to the roof but this is only a temporary fix.

Quite a few homes in Jamaica are made with slab roofs and overtime these roofs will begin to show signs of leaking. You may see from inside that the roof paint begins to fall of or you will see a line in the roof with the paint elevated. If you are seeing water stains of various shapes size and color in your house, you need to investigate the source. The stains may appear as discolored rings or in various hues including gray, yellow or brown.This is a sign of a hairline crack in the roof and now water is settling in the cracks to cause the discoloration of the paint or the lines in the roof.

Keep in mind that even concrete that is free of cracks or damaged is still very porous and able to retain moisture. The next time rain falls, we suggest that after the rain stops falling that you go on top of your roof and you will see puddles or small pools of water. This is where water can soak through the porous roof and travel the the small holes and cracks and eventually leak inside of your house or building. The best option is to waterproof the entire roof, regardless of the where the leak sites are present. For this, you will need to first clean the entire roof surface with a pressure washer. Fill large cracks with mortar or roofing cement, and then apply a good prime.  The next step if to apply Sika Roof Primer and then once it dries you apply the Sika Roof Membrane

One common practice when repairing roof leaks in Jamaica is to check and repair the area just above the leak. This is less costly and labor intensive, but the actual source of the leak may be somewhere else. When you have a leak make sur to have the roofing specialist, check your plumbing lines, check for ponding (puddles of water), and check the entire roof surface.

Open Penetrations

Roof penetrations are found on many flat concrete slab roofs. Roof penetrations are AC units, vents, drains, pipes, steel protuding from the roof and other systems that come through the concrete roof.

Sika has a decade-long tradition to take Sarnafil® roofing membrane samples from certain roofs in North America and Europe to document durability of Sika’s roofing membranes in exposed applications. With average tested roof age being over 20 years old, the oldest is 49 years old, which was installed in 1967 on a project in Persoucio, Switzerland using Sarnafil® G 410-12 PVC membrane. Considering the age and the condition of the roofs analyzed, the data indicates that a properly formulated, properly maintained, reinforced vinyl roof membrane system performs in excess of 20 to 30 years in various climates throughout Europe and North America.

Solutions For Solar Roofs


These are becoming increasingly popular in Jamaica West Indies. More and more building owners see the opportunity to make effective use of their roof space to make a contribution to the environment through sustainable electricity production. Such installations are investments intended to provide a return over the long-term.

Therefore, the roof itself needs a proven track record of high performance with low maintenance requirements as a critical component of solar applications that have an expected service life of 20+ years. Sika has years of experience in the manufacture of liquid and single ply membranes
that can live up to the demands for performance and life expectancy not only as stand alone waterproofing systems, but also ideal substrates for
a variety of solar applications. For the main Photovoltaic technologies currently available, Sika can o«er an ideally suited solution that ensures the overall performance of the solar application with as little maintenance and interruption as possible.
Sika has created “Solar Parks” at its own facilities to showcase its expertise and flexibility of dealing with solar systems used in rooftop applications.


Certain rooftop solar systems absorb light not only from the sun to produce electricity but also from the reflective roof surface itself – in some cases
increasing the e¹ciency of the solar cell up to 15% (depending on the local conditions). Sika’s highly reflective liquid and sheet membranes make a significant contribution to increased electricity production from the same area of solar roof space.
