In our climate, shingle curling is often caused by a combination of intense summer heat, moisture from high humidity, and poor attic ventilation. When heat gets trapped, it essentially 'cooks' the shingles from below, causing them to deform. The fix depends on the extent. For a few curled shingles, we can often perform a targeted repair. However, widespread curling usually indicates the roof system is failing and a replacement with modern, heat-resistant shingles and improved ventilation is the most reliable, long-term solution for your Mount Vernon home.

Roof valleys are the most critical drainage points on your roof, channeling massive amounts of water during our heavy Southern Illinois rains. Leaks here are common due to worn valley metal, improper flashing installation, or debris buildup causing water to back up. The best repair method is a professional assessment. We often replace the valley flashing with a wider, more durable metal system and integrate it seamlessly with new underlayment and shingles. For older roofs, a complete roof valley replacement as part of a larger repair is the most effective way to stop the leak permanently.

This is a key question for Mount Vernon homeowners. As a general rule, isolated issues like a small leak in one valley or damage from a single fallen branch often warrant a repair. However, if you're experiencing widespread shingle curling, multiple leaks, or your roof is approaching 20+ years old, a replacement is usually more cost-effective and reliable in the long run. We provide a thorough, no-obligation inspection to assess the age, extent of damage, and underlying causes (like ventilation) to give you a clear, honest recommendation tailored to your specific situation.
