FAQs
What is roof flashing and why is it critical for Andersonville homes?
Roof flashing is a thin, water-resistant material—usually metal—installed at joints, valleys, chimneys, skylights, and wall intersections to channel water away from vulnerable seams. In Andersonville, where spring downpours and lake-effect snow can soak a roof for days, intact flashing prevents water from wicking under shingles and damaging the wood deck, insulation, and interior ceilings. Without properly installed and sealed flashing, even a brand-new roof can leak within months.
How can I tell if my roof flashing is failing?
Common red-flags include: 1) visible gaps or lifting around chimneys or vents; 2) rust, pitting, or corrosion on metal flashing; 3) water stains on interior ceilings or walls, especially after wind-driven rain; 4) shingles curling near roof edges or valleys; and 5) granule loss or soft decking around flashing lines. Because many signs aren’t visible from the ground, a professional inspection—ideally every spring and fall in Andersonville—is the safest way to confirm flashing integrity.
What flashing materials hold up best in Andersonville’s climate?
• Galvanized steel: Budget-friendly and fairly durable, but must be painted or coated to resist salt spray from nearby Lake Michigan. • Aluminum: Lightweight and rust-proof, but prone to denting in hailstorms; requires proper fasteners to avoid galvanic corrosion. • Copper: Premium choice that can last 50+ years, forms a protective patina, and handles freeze-thaw cycles well—ideal for historic Andersonville homes. • Lead or lead-coated copper: Extremely malleable for complex chimneys; offers long life but higher cost. Your contractor will match material to roof type, budget, and local building codes.
Can flashing failures be repaired, or is full replacement always necessary?
Minor issues—such as a lifted edge, cracked sealant, or a single corroded section—can often be spot-repaired by reseating the metal, adding compatible sealant, and replacing a few shingles. However, if flashing is extensively rusted, improperly lapped, or was installed beneath old siding, full replacement is safer and more cost-effective long term. A qualified Andersonville roofer will photograph trouble spots and explain whether repair or replacement meets Chicago building codes and manufacturer warranties.
How much does flashing repair or replacement cost in Andersonville?
Prices vary with roof pitch, access, and material, but typical 2024 local ranges are: • Simple step-flashing repair on one wall or dormer: $300–$600. • Chimney flashing replacement (counter- and step-flashing): $800–$1,500 depending on masonry work required. • Full-valley metal flashing replacement: $15–$25 per linear foot. Premium copper or complicated historic restorations can run higher. An onsite assessment allows an accurate estimate; remember that timely repair almost always costs less than fixing extensive interior water damage later.
How quickly should flashing issues be addressed, and what happens if I delay?
Because flashing seals roof penetrations, even a small failure can let water travel along framing and drip far from the origin. In Andersonville’s freeze-thaw cycles, trapped moisture expands and contracts, widening gaps and accelerating rot, mold, and attic insulation damage. Delaying repair often turns a $500 flashing job into a multi-thousand-dollar roof-deck or drywall replacement. Industry best practice is to schedule service within a week of noticing a leak or visible flashing defect, and sooner if a major storm is forecast.
