Roofs are an essential part of any construction, not only for the protection they afford against adverse weather conditions such as wind, rainwater and damp, but also because they ensure thermal and acoustic insulation as well as providing the right finished look.
Various factors can interfere with and influence the performance of the surfaces of a roof, one of the most common and often overlooked being perforations. Although necessary, these are problematic because they penetrate surfaces and can become direct entry points for water infiltration.
Perforations are most frequently found in:
Hydraulic systems such as storm water drains
HVAC systems
Metallic profiles
Cable routes
Photovoltaic and solar panels
Ventilation ducts
Smoke extraction ducts
Electrical ducts
Railings
In this article, we’ll focus our analysis on two of these sources which cause the most problems for homes.
The site where a pipe or post passes out through a roof is, potentially, a direct entry point for water infiltration into the building, meaning that effective sealing is crucial. If these perforations are not sufficiently waterproofed from the outset, leaks will inevitably appear, leading to serious problems inside the building.
Water infiltration problems can flare up when pipes or poles are installed without sufficient care or attention to detail. The most commonly applied fixes in these cases are galvanized or zinc-coated sheets, sealants and other short-term solutions. While these measures can be an adequate initial response, the repeated action of wind and rain battering against the components of the repair can cause major issues, due to the constant movement and thermal expansion of the parts. Not only could the appliance bend or come loose from its base, but it can also cause cracks in the base of the surface and generate wear on the materials, resulting in permanent breaches.
When complications begin to appear on the outside of the building, they are immediately reflected on the inside of the building. Often resulting in:
Fissures and cracks in the roof slab
Damp and condensation
Fungus growth
Cracks in the interior mortar lining
Shrinkage of materials
Three easy steps, two words, one definitive solution – Water Stopper. Step 1 – mould the ruler, adaptable to any size or configuration of exit point. Step 2 – apply the sealant to the Stopper mould. Step 3 – fill up the space in the mould, and your infiltration problems are over for good! It’s quick, it’s simple and you can do it yourself – no need for professional help!
