Common signs include water stains on ceilings or walls near chimneys, skylights, or roof valleys, especially after heavy rain. You might also see visible rust, gaps, or lifted metal around flashing points. In our climate, these issues can develop from repeated freeze-thaw cycles and moisture. If you notice any of these, it's wise to schedule a professional inspection to prevent interior water damage.

Flashing rust is prevalent in West Chester due to our humidity and the use of older galvanized steel flashing, which corrodes over time. We address this by removing the rusted sections and installing new, high-quality flashing made from corrosion-resistant materials like aluminum or copper. Proper installation with compatible sealants is key to preventing recurrence and protecting your roof's integrity for years to come.

It depends on the extent of the damage. For minor separation where the material is still sound, we can often reseal and re-secure the flashing. However, if the separation is significant, the metal is severely rusted, or it's a recurring issue, a full replacement of that flashing section is usually the most reliable and cost-effective long-term solution to ensure a watertight seal.
