Differences Between Flat Roofs

 

There are many different types of flat roofs, and they are each designed to meet a different need. The insulation, reflectivity, cost, and longevity of these roofs can vary greatly, so it’s important to know what you’re getting when you make a purchase. 

 

 

 

Many flat roofs are designed with insulation in mind. Of these roofs, spray foam offers the best bang for your buck. Spray foam roofs offer the highest R-value of any roofing system available. Installed on the outside of the roof deck, their high insulation also helps with the interior climate as opposed to insulation that is installed under the roof deck. Other roofing systems aimed towards providing insulation are built-up roofs and metal roofs with interior insulation.

 

 

Other flat roofs are designed to enhanced the reflectivity of the roof. Namely, white roof systems address reflectivity. These roofs decrease heating costs by decreasing the interior building temperature. White roof coatings are among the most prevalent and most rapidly growing roof types providing high reflectivity. Specifically, silicone roof coatings are growing faster than any other roofing segment thanks to their reflective properties. Reflecting around 88% of UV rays back into the atmosphere, silicone roof coatings can drastically reduce the temperature of your building. 

 

 

If you’re looking for a lightweight roofing system, your options change once again. Certain deck boards are extremely lightweight while offering some insulation properties. Thin metal panels are much lighter than a concrete or built-up roof. These lightweight panels are easier on the structure of your building.

 

 

Sometimes an inexpensive roofing option is all you need. These are more common in re-roofing scenarios where the building owner simply needs to get a few more years out of the roof. Some membrane systems offer adequate coverage at a low price tag, as well as most roof coatings. The benefit of roof coatings here is that they can be a long-term solution that provides reflectivity, while still offering a low price tag.

 

 

Depending on what you’re looking for, your roofing choice can vary drastically. If you just want to save money, you might choose one roof, whereas if you’re concerned with sustainability and lower energy expenses, you might choose another.
