As a homeowner, you may not be overly familiar with roof flashing. You might not know what it looks like or understand its importance. At Alan’s Roofing, we know roof flashing is critical in protecting your home from leaks in the most vulnerable areas of your roof. Without high-quality roof flashing, your home is far more susceptible to moisture intrusion, mold growth, and premature roof aging. Don’t risk compromising your roof with inadequate or damaged flashing.

What Is Roof Flashing?

Roof flashing is a thin, sturdy material that channels water away from roof junctures and protrusions such as vent pipes, chimneys, skylights, edges, joints, and valleys. It is commonly manufactured from galvanized steel, copper, or aluminum. Ideally, roof flashing prevents water from penetrating through the outer roof surface to sublayers.

4 Reasons Why Roof Flashing Is Important

Prolongs Your Roof’s Lifespan & Performance

High-quality roof flashing extends your roof’s life by preventing moisture intrusion, improving energy efficiency, and protecting against outside elements, including wind. Water damage is the primary cause of a roof’s premature aging and shortened life.

Protects Your Home’s Interior, Including Insulation

Robust roof flashing preserves your home’s structural integrity and maintains the performance of underlying materials. A leaky roof will cause problems like warped drywall and moist insulation, potentially leading to mold issues. Roof flashing acts as a waterproof barrier.

Reduces The Necessity Of Expensive Repairs

Fixing a roof can cost a homeowner thousands of dollars and cause inconveniences. In the worst-case scenario, a damaged roof may need replacement. Durable roof flashing may eliminate leaks or other issues affecting the roof’s performance.

Stops Water Damage & Mold Growth From Occurring

Water flows wherever gravity directs it. If gaps or cracks exist at joints, junctures, valleys, and openings, water collects and absorbs through the outer surface into sublayers. Airtight roof flashing prevents water from pooling and channels it to the eaves or gutters.
