Roof Preparation and Inspection

We start by thoroughly inspecting the roof deck to identify damage or debris. A clean, smooth, and dry surface is critical to ensure proper EPDM membrane adhesion. Any old roofing materials that could interfere with bonding are removed.



Repairs are made to fix structural issues or uneven spots. We then clean the surface using appropriate tools, followed by applying a primer to enhance membrane attachment. This careful preparation minimizes installation errors and extends the roof’s lifespan.

Membrane Application and Adhesion

Applying the EPDM membrane requires accurate measurement and careful handling. We measure and cut the membrane to fit the roof’s exact dimensions, minimizing waste and ensuring a tight seal around penetrations and edges.



In adhesive installations, we use high-quality water or solvent-based adhesives to bond the membrane securely to the roof deck. The membrane is rolled out gradually, pressed firmly for full contact, and adjusted to prevent wrinkles or folds that could cause leaks.

Finishing Touches and Quality Control

Sealing seams and edges is essential to prevent water infiltration. We apply specialized seam tape or liquid sealants after priming, focusing on joints, drainage areas, and roof penetrations for a watertight seal.



Flashing and trim components are installed at all roof transitions and edges to reinforce durability. Our team conducts detailed inspections to spot any imperfections or potential weak points before project completion.

Safety and Compliance for EPDM Roofs

We adhere to all industry safety standards and local building codes throughout the EPDM installation process. Our team uses proper protective equipment and follows safe work practices to protect both workers and the property.



Documentation and permits required by Joliet, IL regulations are managed professionally to ensure full compliance. This structured approach mitigates risk and guarantees your roofing project meets all legal and quality requirements.

Durability and Weather Resistance

EPDM roofing is highly resistant to UV rays, ozone, and extreme temperatures, maintaining its integrity in Joliet’s diverse climate. This synthetic rubber material does not crack or become brittle with age, unlike some other roofing types.



Its flexibility allows EPDM roof membranes to handle thermal expansion and contraction without damage. This resilience significantly reduces the risk of leaks and structural issues.

We routinely recommend EPDM for low-slope roofs because it withstands ponding water and harsh weather events better than many alternatives. It also resists hail and wind uplift, making it a solid choice for commercial buildings.

Cost Efficiency and Maintenance

Installing EPDM roofing typically costs less upfront compared to other flat roofing options like TPO or PVC. Its simple, single-ply design helps lower installation labor time and complexity.



Maintenance requirements are minimal, as EPDM roofs rarely need repairs if installed correctly. We advise regular inspections to clean debris and check seams, but replacement intervals often exceed 20 years.

The material’s longevity minimizes frequent roof replacements, reducing lifecycle costs for commercial property owners. We help clients maximize value by recommending proper installation and preventative upkeep.

EPDM's Environmental Features

EPDM rubber roofing contains no harmful substances and is fully recyclable at the end of its service life. Its black surface absorbs heat, which can be advantageous in colder months for energy savings.



For clients seeking year-round cool roofing, white or reflective EPDM membranes are also available, helping reduce energy costs by lowering cooling loads in summer.

Using EPDM supports sustainable building practices due to its durability, recyclability, and energy efficiency. These factors contribute to smaller environmental footprints for commercial buildings in Joliet and beyond.
