Many buildings in South Chicago have a flat roof, many of which are commercial or industrial buildings. There are a few reasons why people choose flat roofs compared to their sloped counterparts.
Flat roofs construction Types
Built Up Roofing (BUR)
This is the generic term for roofs that are built up by many alternating layers of roofing felts and waterproofing materials. These can include asphalt, coal tar pitch, cold application adhesive, and insulation plus others.
It is more commonly known as a “tar and gravel” roof as they are finished with a layer of gravel, or some other crushed rock/ mineral.
MBR (Modified Bitumen Roof)
The construction from these is slightly different as they are constructed from fiberglass-based asphalt sheeting. These are applied in layers with hot bitumen in between each layer.
These are the most common commercial flat roof materials rather than on residential buildings, yet it can be a good alternative should you so wish.
Built up roofing is the cheapest option choice, yet over time the intense sunlight breaks down the asphalt base leaving it needing replacing sooner than other options.
South Chicago Roofing spends more time installing this sort of flat roof deck materials than any other. They are the most practical, modern and the most reliable. This roofing type also comes in two varieties.
Thermoset membranes which are rubber polymers and use less tape or adhesive to form the watertight seal that is required on the edges. On the other hand, there are Thermoplastic membranes which are constructed from plastic polymers and have their waterproof seals formed by heat or chemical welding.
Included with these is also a protective reinforcement layer of either fiberglass or polyester which gives them their strength and stability.
This type of roof also lasts longer than the other kinds, so it can be a better choice, regardless of the fact that they do cost a little more.
