Tapered insulation is a roofing feature you shouldn’t underestimate. It can go a long way in maintaining your roof and giving it a longer roof shelf life. The purpose of tapered roof insulation systems is to drastically minimize the dangerous effects of ponding or standing water on the membrane of your roof deck, and it’s especially important for flat roofs. In most cases, tapered insulation comes as a preformed rigid insulation feature used on roofs at drains or roof intersections. It requires a slight change in elevation at the surface.
The Problem of Poor Drainage
Poor drainage is one of the most important things you have to consider when it comes to long-lasting roofing. Large amounts of accumulated or ponding water can be the greatest threat to an existing roofing membrane. Roofing systems without proper drainage can result in damage that is even more destructive than the damage caused by wind, other natural elements or gradual wear-and-tear.
There are many negative effects of this poor drainage. It significantly shortens the expected life of the membrane, which can void your membrane and roofing warranty. It can also lead to serious problems like bacterial or unwanted vegetative growth on the roof, and structural deflections of the roof deck.
Heavy rainwater and snow can cause damage to your roof which, more often than not, can be costly. Home insurance doesn’t usually cover pre-mature roof failure as well as minor problems. As such, it’s essential that you preempt and prepare for the dangers of poor drainage. You need to insure a safe and long-lasting roof before any insulation-related problems arise.
Tapered Insulation and its Benefits
The answer to reduce the impact of ponded water is tapered insulation. Tapered insulation enhances positive rooftop drainage while also providing insulating value. Most tapered insulating roof systems direct water to drains and scuppers, reducing the amount of ponding water in the first place. This can greatly reduce the need for maintenance and the amount of stress placed on the roof. In short, the service life of your roof becomes extended.
The insulating properties of tapered insulation systems ensures a cooler roof. It lessens the amount of sunlight and heat trapped by your roof, which also leads to a cooler building atmosphere overall.
Tapered insulation systems are equally compatible for new and replacement construction, and they are easy to install. You also don’t need to sacrifice the structural and economic advantages of a flat roof deck. A 1/4 inch per feet minimum field slope is generally recommended.
Some tapered insulation systems are made of expanded polystyrene. This material ensures long-term thermal performance, stability, and consistent moisture-resistance. Other tapered insulation systems make use of other equally effective materials.
There are many things to consider when you want to add tapered insulation. For example, a designer has to think of the details of the roofing area as well as budgetary concerns. As such, there are many different types of slopes that you can design for your roof.
