What is a Flat Roofing System?
Flat roofs are engineered with the primary purpose of waterproofing the roof area and to provide a protective covering for all the materials beneath them. Flat roofs or Built-Up Roofing should be designed with positive drainage. Most flat roofing material manufactures and trade associations require a flat roofing system to be designed so that water is not standing or ponding for longer than 48 – 72 hours. A wide array of materials are used to create the protective membrane depending on the roof style and are applied in a myriad of ways. Many flat roofs today, installed correctly within proper specs, can perform for 15 years or more with great efficiency
Common Flat Roofing Failures, Leaks and How to Prevent Them
Common flat roofing problems are caused if they are incorrectly installed along with other components of the roofing system. This includes improper ventilation, inadequate substrate, missing vapour barrier or flashings. Premature membrane degradation and subsequent roofing system failure could occur much sooner than warranted, causing costly repairs in the future. One way to prevent leaks, extend and preserve the life of a flat roof membrane covering is to install a Roof Coating System. Home and buildings alike need to prevent moisture and water intrusion. With rising energy cost building owners are constantly looking for ways to reduce these costs. Karnak Building Envelope Sealers reduce air and moisture flow in or out of the building depending on your needs. Reflective Coatings reduce roof surface temperature helping extend the life of the roof; they also reduce energy consumption by preventing heat absorption. Roof coating systems designed with re-enforced seam sealing and flashing tapes, waterproofing base coatings and energy efficient water proofing reflective top coatings are a cost effective way to fulfill all of these needs. MrRoofRepair can tailor a specific solution for your roof needs and budget.
Why is positive drainage for a Flat Roof so important?
Improperly installed, degraded, damaged and missing membranes are the primary causes for flat roof leaks. Large amounts of water will pool, causing strain on the seams which will break the bond and leak into the home. One issue is that once water does penetrate, damage can often go unnoticed for a long period of time as it soaks the roof deck and any insulation and structure beneath. This can lead to expensive damage from the rot which often develops and if left can weaken the roof structure. This, in turn can lead to mold growth which creates a health risk for people and animals inside the home.
Another common reason for failure of flat roofs is lack of drain maintenance where leaves and debris can block water outlets such as gutters. This can cause water to freeze which will break up the roof surface as it expands. Flat roofs are also sensitive to human traffic. Anything which produces a crack or puncture in the waterproofing membrane can easily lead to leaks.

Many flat roofs cannot be viewed from the ground, so if you’re not sure, or you think you might have a problem call a professional to inspect and report on remedial work. Regular maintenance inspections could help extend and preserve the life and prevent costly damage to your home.
