Asphalt shingle roof in Illinois
Last updated: September 24, 2026
For residents of Illinois, particularly within the vast Chicago metropolitan area, the installation of asphalt shingles must account for the region's pronounced continental climate, characterized by hot summers and bitterly cold winters with significant snowfall. This necessitates a roofing system engineered for resilience against extreme temperature fluctuations and precipitation.

The climate in Illinois, and especially in Chicago, demands a robust approach to asphalt shingle roof installation. The annual cycle of freezing and thawing, coupled with heavy snow loads during winter, can compromise less durable roofing systems. Proper underlayment, especially in eaves and valleys, along with adequate ice and water shield, is critical to prevent water infiltration and structural damage. The prevalent housing stock in Chicago, featuring a mix of historic structures and contemporary homes, often requires detailed site assessments to ensure the underlying structure can support a new asphalt shingle roof and that ventilation is optimized for both summer heat and winter cold.
When undertaking an asphalt shingle roof project in Illinois, understanding local building codes and permitting requirements is essential. Municipalities across the Chicago area may have specific ordinances regarding roofing materials, installation procedures, and contractor licensing. A qualified roofing contractor will be proficient in these local regulations, ensuring a compliant and efficient installation. Evaluating potential providers involves assessing their experience with Illinois's climatic conditions, their proficiency in applying asphalt shingles according to manufacturer specifications for wind and hail resistance, and their commitment to using quality underlayment and fastening systems that will withstand the state's rigorous weather patterns.
Common questions
How much does it cost to have a roof installed?
The cost of an asphalt shingle roof installation is influenced by numerous factors. These include the complexity of your roof's geometry, the specific type and quality of asphalt shingles chosen, and the necessary preparation of the existing roof deck.

What is the average cost to have a new roof?
While an 'average cost' can be misleading due to project variability, key determinants for a new asphalt shingle roof include the total square footage requiring coverage and the labor involved in the tear-off of old materials.

What are the steps to installing a roof?
The process begins with a thorough inspection and preparation of the existing roof deck, followed by the application of underlayment and ice and water shield in critical areas. Next, starter shingles are installed, followed by the main field shingles, ensuring proper overlap and fastening according to manufacturer guidelines and local building codes.
What is the cheapest type of roof to install?
While basic 3-tab asphalt shingles generally represent a lower initial material cost compared to architectural or premium asphalt shingles, the long-term value and performance should be considered. Factors such as durability, warranty, and wind resistance significantly affect the overall cost-effectiveness of any roofing material choice.
What is the 25% rule for roofing?
The 25% rule, often discussed in the context of asphalt shingles, refers to the principle that if a roof has more than 25% of its shingles damaged or missing, it is generally more cost-effective to replace the entire roof rather than attempt localized repairs. This guideline helps homeowners make informed decisions about when repair becomes impractical.
How do Illinois winters impact asphalt shingle roofs?
The severe cold and heavy snowfall common in Illinois winters can lead to ice dams and water infiltration if an asphalt shingle roof is not properly installed. Adequate ice and water shield, along with proper ventilation and shingle fastening, are crucial for protecting your roof against these harsh conditions.
