At Universal Roofing and Contracting we repair and replace any type of commercial roofing philadelphia and residential flat roof.   Our crews are specially trained and certified to handle any type of flat roofing materials. These professionals install flat roofing only with materials like built–up roofing, EPDM, TPO, and modified bitumen.  Whether it is a commercial or residential flat roof, we follow all of the manufacturer’s specifications to provide the best possible warranty.  We service the following Flat Roof types:

Built Up Roof Membrane - Universal Roofing PhiladelphiaBuilt Up Roof Membrane:  A built-up roof (Smooth Built-Up, Ballasted Built-Up, or Tar and Gravel) is a class of low-slope roof that consist of laying down several layers of tar and water resistant materials and then covered with gravel.  Many old buildings with low slope or flat roofs are topped with built-up roofing made from layers of asphalt-coated roofing felt. The top layer is usually covered with rock or gravel, which serves as a ballast to hold the roofing material down and protect it from UV damage. Built-Up Roofs with gravel surfacing are also known as Tar and Gravel roofs. The typical life span of a built-up roof is 10 to 20 years depending on weather conditions.

Hypalon Roofing Membrane Philadelphia Commercial Roofing - universal roofingCommercial CSPE Flat Roof:   CSPE (Hypalon) Commercial Flat Roofing is made of chlorosulfonated polyethylene, more popularly known as Hypalon®, a reinforced, heat-weldable, membrane based on DuPont Performance Elastomers synthetic rubber.  A thermoplastic allows it to be hot air welded.  Once installed and exposure to the environment, the membrane’s individual polymer components form a highly stable, synthetic rubber material. CSPE roofs provide high resistance to a broad range of chemicals and is suited for commercial, industrial and institutional applications.  The material is available in white and light gray (special order), nominal 45 mil (1.14mm) and 60-mil (1.52) thickness in standard 76.5-inch wide rolls x 100-feet long (1.9m wide x 34m long).

EPDM Roof for Commercial - MultiFamily - Industrial Roofs - Universal Roofing PhiladelphiaCommercial EPDM Flat Roof:   EPDM Roofing (Ethylene Propylene Diene Monomer) is durable and resistant to general wear and tear and an excellent material for flat or low slope roofing.  EPDM roofing is a synthetic rubber that acts as a roofing membrane special for flat roofs. EPDM roofing membrane is versatile and offers superior flexibility, high strength, and outstanding weathering in practically all climates – ranging from -45 to 100 degrees Celsius with no signs of aging.  EPDM roofs will not crack, split, or peel, and is completely resistant to atmospheric pollution. EPDM roofing is also environmentally friendly, and is unaffected by UV light and ozone. An EPDM roof system has a life expectancy of about 20 years, during which next to no maintenance is required.

Bitumen Roof - Universal Roofing Philadelphia PACommercial Modified Bitumen Flat Roofing:  Modified Bitumen is a roofing membrane consisting of asphalt and plastic or rubber polymers, and is a step above asphalt built up roofing.  Modified bitumen displays the built in redundancy of asphalt built up, as well as the UV resistance and flexibility of a modified membrane – because it uses polymers which allow the asphalt to take on its most beneficial qualities. Typical life span of modified bitumen is 10 to 20 years, depending on climate and weathering.  Modified bitumen is generally applied using a heat application process that melts the seams together to create a seal, yet sometimes a cold adhesive application system is used.  Modified Bitumen can reach temperatures of up to 150 degrees but it can effect HVAC performance  the performance air-conditioning equipment unless an elastomeric coating is used.

Consideration when selecting a New Flat Roof.

Superior Durability and Longevity: resistance to ozone, UV radiation, extremes of low- and high-temperatures, and ultimately aging.
Quick Installation:  selecting products in sheet sizes up to 15m in width and 61m in length, resulting in fewer seams and less installation time.
High Flexibility and Elongation: choosing products that remain highly flexible even at temperatures down to -45°C and stretch to accommodate building movements.
Low Life-Cycle Cost:  selecting products that require little or no maintenance. Combined with the inherent durability and competitive installed cost result in a very low life-cycle cost.
Environmentally Friendly: we use inert materials with limited environmental impact during manufacture and use.
