Krhounek Roofing | Roofing Services in Downers Grove, IL 60515

In Downers Grove, shingle curling is often caused by moisture absorption, improper attic ventilation, or aging materials due to our seasonal temperature swings. The fix typically involves a professional inspection to determine the underlying cause. For localized curling, we can often replace the affected shingles. However, if the curling is widespread, it may indicate a ventilation issue or that a full roof replacement is the most cost-effective, long-term solution to prevent further damage.

Roof flashing around chimneys, vents, and skylights can lift due to thermal expansion and contraction from our Illinois winters and summers, or from improper initial installation. At Krhounek Roofing, we repair lifted flashing by carefully removing the old material, inspecting the underlying deck for water damage, and installing new, code-compliant flashing sealed with high-grade waterproofing cement. This precise process ensures a watertight seal that can withstand our local weather for years to come.

The best way to know is with a professional assessment. Generally, if issues like curling or flashing problems are isolated to a small section and your roof is relatively new, a repair is likely sufficient. However, if these problems are widespread, you're finding granules in your gutters, or your roof is approaching 20+ years old, a replacement is often more economical and reliable. We provide honest, detailed evaluations to help you make the right choice for your home and budget.
