A well-installed roof does more than just shield your home from the elements—it relies on critical components like flashing to ensure long-lasting protection.
Roof flashing is a durable, waterproof barrier—typically made of thin sheet metal, that professional roofers install to protect vulnerable areas where the roof meets vertical surfaces (like walls, chimneys, or skylights). Unlike shingles, which shed water across their surface, flashing is strategically placed beneath roofing materials to create a tight seal and divert water away from gaps.

Roof flashing is a durable, waterproof barrier—typically made of thin sheet metal, that professional roofers install to protect vulnerable areas where the roof meets vertical surfaces (like walls, chimneys, or skylights). Unlike shingles, which shed water across their surface, flashing is strategically placed beneath roofing materials to create a tight seal and divert water away from gaps.
Flashing acts as a barrier, directing water away from vulnerable areas where the roof meets other structures. If flashing is damaged, corroded, or improperly installed, water can seep into your home. This causes roof leaks that damage ceilings, walls, and insulation.
Regular inspections and timely flashing repairs or replacements can prevent these expensive and hazardous issues.
Chimney flashing requires extra attention because chimneys are among the most common sources of roof leaks. Since chimneys expand and contract with temperature changes, their flashing must be expertly installed to remain flexible and watertight. Walsh Residential Roofing uses high-quality materials—such as aluminum, copper, or galvanized steel—and industry-best practices to ensure a secure seal.
Damaged or poorly sealed flashing can create gaps and air leaks, allowing warm air to escape in winter and cool air to seep out in summer. This forces your HVAC system to work harder, increasing energy bills. Properly installed flashing helps maintain a tight thermal envelope, improving your home’s energy efficiency and comfort.
Cracked, bent, or discolored flashing can make even a new roof look aged and neglected. By repairing or replacing worn flashing, Walsh Residential Roofing can restore your roof’s clean, polished appearance while extending its lifespan.
