Cedar Roofing | Roofing Services in Glenview, IL 60025

In our Glenview climate, the most frequent cause is failing or degraded sealant around the skylight frame. Temperature fluctuations and freeze-thaw cycles can cause the flashing and seals to crack over time, allowing water to seep in. A professional inspection can pinpoint if it's a seal issue, flashing problem, or something else entirely.

Signs inside your attic include soft, spongy spots you can feel underfoot, dark stains, or a musty odor. From outside, you might see sagging roof lines. This is critical because rotten decking compromises your roof's structural integrity. It can't properly support new shingles and poses a safety risk. We assess the extent of the damage to determine if repair or full decking replacement is needed.

For lasting protection, we focus on a complete system: using durable, impact-resistant shingles rated for our midwestern storms, ensuring proper ventilation to prevent ice dams and moisture buildup, and installing high-quality underlayment as a critical secondary water barrier. A comprehensive approach, rather than just a surface fix, is key to preventing the leaks and rot we commonly see.
