What is Involved in Installing Built-Up roofing

Built-up roofing is a roofing system that is popular for both residential buildings as well as commercial premises. There are a lot of different types and different materials used in the process. Primarily used for flats roofs and low-pitched roofs, built-up roofs are best when installed in warmer climates, not colder ones.

As a roofing contractor, we recommend built-up roofs for installation only in warmer climates. In cold climates, there is ice built up in the drainage areas and pond water, or water that pools on the roof, which can cause roof failure and can lead to a faster deterioration of the roof.

Wide Application

Built-up roof systems can be used for any application.We use them for specific roof structures – on flat roofs, specifically the three-ply fiberglass roof systems with Elastomeric coating. We also use them when we have tear-offs and re-roofing, and on roofs that are under construction. The system is built up because it has multiple layers of waterproofing membranes, which are traditionally applied using hot tar.

On top of that, it is a cool coating, which is where we get a variety of energy-efficiency advantages, helping our customers save a lot of money on their cooling and heating bills. The coatings are usually white in color and manufactured to have high reflectivity of the solar reflectance, which means they reflect visible infrared ultra violet wavelengths from the sun. That, in turn, reduces the heat transfer into the building from the roof. This means that the home stays cooler – and you save on your cooling bills.

Energy-Saving Products

By using built-up roofs, homeowners can save huge cost on their cooling bills. The majority of our customers are now beginning to recognize that energy-saving products – in particular ones that are Energy Star rated – are worth having. Usually, a built-up roof will save you up to 10 to 20 percent off your cooling bills on hot days. In warm climate areas, from May through September, we probably average about 93 degrees to 105 degrees Fahrenheit during the summertime during the day, so installation of these roofs can make a lot of sense – and cents.

In addition, it is fairly straight-forward to install built-up roofs. The process, from a full tear-off to a re-roof, will take, on average, from three to four days for a residential roof. It is done with minimal disruption to the customer, and homeowners can stay in the residence while the built-up roof is being installed. We will be working on the rooftop and just have one area where we will have our truck and a dumpster for the tear-off. As a roofing contractor, we do built-up roofs for commercial facilities as well.

What You Should Remember

As a homeowner, you should remember that built-up roofs are not designed to be walked on. A built-up roof membrane consists of piles of felt – saturated and coated – and mats, between which layers of bitumen are applied. If you are walking on the roof, you can cause the membrane to contract and tear the roof quicker, or have a membrane leak.

Your roof is usually where you have your cooling and heating systems located, so always have a roofing contractor come out afterward to inspect and make sure there are no punctures in the membranes or cracks which the workmen have made when they were up there. And when you look for a roofing contractor, always play it safe and look for a licensed, bonded and insured roofing contractor.
