Choose your city
Illinois experiences a wide range of weather conditions, from frigid winters with heavy snowfall and ice accumulation to hot, humid summers. EPDM roofing's inherent durability, UV resistance, and flexibility make it an excellent choice for these demanding climates, particularly for the prevalent low-slope and flat roofs found on many commercial and residential structures in Chicago and its suburbs. Proper installation is critical to ensure the membrane can withstand significant thermal expansion and contraction, as well as the abrasive effects of wind-driven debris and hail. When selecting an EPDM installer in Illinois, prioritize those with a thorough understanding of state and local building codes, particularly those enforced within the City of Chicago, and a demonstrated history of successful installations in similar environmental conditions.
Common questions
What is the cheapest type of roof to install?
EPDM is a highly cost-effective material for low-slope roofs, offering a balance of affordability and long-term performance. While asphalt shingles may be cheaper for steep slopes, EPDM's durability, energy efficiency, and resistance to weathering often result in a lower overall cost of ownership, especially in Illinois' varied climate.
What is the 25% rule for roofing?
The 25% rule is a widely accepted guideline in roofing, indicating that if damage or deterioration affects more than a quarter of a roof's surface area, a complete replacement is typically more advisable than localized repairs. This approach ensures the integrity of the entire roof system and prevents future issues.
What is the cheapest month for roofing?
In Illinois, the shoulder seasons, such as late spring or early fall, often present the most opportune times for roofing projects. Contractors may have more availability during these periods, potentially leading to more competitive pricing for EPDM installations due to reduced demand.
Which company is the best for roofing?
The 'best' roofing company is one that demonstrates extensive experience with EPDM installations in Illinois' climate, possesses all necessary licenses and insurance, and has a portfolio of satisfied clients. Expertise in navigating Chicago's specific building regulations is a key differentiator for local contractors.
What is a fair price for a new roof?
A fair price for a new EPDM roof is determined by factors such as the roof's surface area, its slope, the grade and thickness of the EPDM membrane utilized, and the complexity of the installation process. Specialized roof details and the need for ancillary components will also influence the overall cost.
How does Illinois' climate impact EPDM roof choice?
Illinois' harsh winters with heavy snow loads and the intense heat of summer necessitate an EPDM system that is both robust and flexible. Proper seam adhesion and the use of UV-resistant membranes are vital to prevent premature aging and ensure the EPDM performs optimally against thermal stress and extreme weather.
