Illinois' climate is known for its cold, snowy winters and hot, humid summers. Winter months can bring significant snowfall, freezing temperatures, and ice dams, requiring roofing materials that can effectively shed water and resist freeze-thaw cycles. Summers often feature high temperatures and humidity, which can stress roofing materials over time. The type of shingle selected plays a direct role in the roof's ability to protect against moisture intrusion and temperature extremes. Understanding how different shingle types perform under these conditions is crucial for long-term durability. Proper installation by experienced professionals familiar with Chicago's building regulations ensures your roof system functions optimally.
Common questions
What are the common roof shingle types used in Illinois?
In Illinois, asphalt shingles are a prevalent choice, offering a good balance of affordability and performance for the state's climate. Metal roofing is also an excellent option, known for its resilience against hail and wind, which are common in the Chicago area. Architectural shingles provide enhanced aesthetics and durability. We help you select the best fit for your home.
How do Illinois' seasons affect roof shingle lifespan?
Illinois winters with heavy snow and ice can put significant stress on shingles, leading to potential cracking and ice dam formation. Summer heat and humidity can cause materials to expand and contract, potentially shortening their lifespan. The frequent freeze-thaw cycles are a major factor in shingle degradation. Choosing materials designed for these extremes is vital for your Illinois roof.
What is the 25% rule for roofing in Illinois?
The 25% rule in roofing typically addresses roof slope and the methods required for proper water drainage. Slopes below this percentage might necessitate specific underlayment or installation techniques to prevent water pooling. In Illinois, particularly during periods of heavy rain or snowmelt, adhering to these slope and drainage requirements is essential for preventing leaks and structural damage.
What are the steps to installing a new roof in Illinois?
Our installation process begins with a detailed inspection and the removal of your existing roofing layers. We then assess and repair the underlying roof deck for integrity. A critical step involves installing ice and water shield underlayment, especially important for Illinois winters. Finally, the chosen shingles are applied according to manufacturer specifications and local building codes in the Chicago area.
What is the cheapest type of roof shingle to install in Illinois?
The most budget-friendly shingle option for installation in Illinois is generally the 3-tab asphalt shingle. These provide a lower initial cost. However, it is important to consider their longevity and resistance to Illinois' demanding weather conditions, as other materials may offer better long-term value and protection.
How do I choose the best roof shingle for my Illinois home?
When selecting shingles for your Illinois home, prioritize materials that can withstand cold winters with snow and ice, as well as hot, humid summers. Asphalt shingles offer a practical balance of cost and performance. Metal roofing provides superior resistance to hail and wind, common occurrences in the region.
