Whenever a person is trying to run a business, the last thing they want to think about is a failing roof. Sadly, this can happen quite frequently with commercial buildings because these properties can sit for extended periods of time between leasing. When a roof fails, it can cost a business some very expensive repairs even though many commercial businesses have simple roofing systems.
There are several types of low-pitched roofs, but Flat Roofs in Peoria IL, are the most common. This doesn’t imply a specific type of flat roof is more functional than another because many progressive companies use polymers such as PVC (Polyvinyl Chloride) or TPO (Thermoplastic Polyolefin) to cover large buildings. The plastics can be stretched over the roof structure and are eventually secured in place.Another option for Flat Roofs is the rubber membrane. This covering is made from EPDM (ethylene propylene diene terpolymer), which is a synthetic rubber. Unfortunately, EPDM doesn’t work well in all climates. It can be affected by extreme heat and cold. This makes EPDM a poor choice for certain types of roofs. A flat roof actually uses a low or gradual slope for shedding water. This allows the roof to drain water without losing any of the aggregate used to keep a flat roof in place.The most common type of low pitched or flat roofs in the Peoria IL area use BUR (Built-Up Roofing). This roof covering is a soft product that can be somewhat difficult to install. The typical BUR roof begins with an OSB (Oriented Strand Board) or plywood covered deck. Decking like this is strong enough to handle the weight of roof coverings. Over the decking should be a layer of roofing felt or tar paper. This material is installed to protect the underlying decking.Over the decking should be one or more layers of asphalt or an asphalt mix designed for durability. Next should come multiple layers of roofing felt and asphalt. Rotating between asphalt and a membrane creates a roofing solution that is very durable. In fact, the only thing missing is the aggregate. Most flat or BUR installations use small pebbles such as pea gravel to hold the felt or roofing paper in place.
