Roof flashing is a critical component of any roofing system, designed to direct water away from vulnerable areas where shingles meet walls, chimneys, or valleys. United Contracting & Roofing LLC in Greenville, SC, highlights the significance of proper flashing installation and maintenance to ensure the longevity and effectiveness of your roof.

What is Roof Flashing?

Roof flashing is typically made from thin metal sheets such as aluminum, galvanized steel, copper, or stainless steel. These materials are used to create a waterproof barrier at joints or intersections on the roof, preventing water from seeping into the structure. Flashing is essential where roof shingles butt against walls, chimneys, and valleys, providing an additional line of defense against water intrusion.

Types of Roof Flashing

Valley Flashing

Valley flashing is used in the low areas between two intersecting roof slopes. This type of flashing reinforces the valley, a natural water conduit, to prevent leaks due to the higher volume of water flow.

Apron Flashing

Apron flashing is L-shaped and is installed at the base of roof penetrations like chimneys and dormers. This flashing type helps channel water away from these protrusions, safeguarding the roof’s integrity.

Step Flashing

Step flashing involves placing pieces of metal under each shingle where the roof meets a vertical surface, such as a wall or chimney. This technique ensures that water is directed away from these junctions, preventing leaks.

Counter Flashing

Counter flashing is used in conjunction with step flashing, particularly around chimneys. It is embedded into the mortar joint and sealed with roofing cement to provide a watertight barrier.

Common Roof Flashing Problems

While roof flashing is designed to be durable, it can still face issues over time due to various factors:

Age

Over time, flashing materials can wear out and become less effective. Rust and corrosion are common in older flashing, necessitating replacement during roof repairs.

Extreme Weather

Flashing can be damaged by extreme weather conditions, including high heat, strong winds, and large hail. These elements can cause expansion, contraction, and physical damage to the flashing, creating potential leak points.

Poor Installation

Improperly installed flashing is prone to failure. It is crucial to have flashing installed by professionals to ensure it performs its protective role effectively.

Foundation Settling

Movement in the building’s foundation can cause flashing to crack or pull away from the roof. Regular inspections by a trusted roofer can help identify and address these issues early.

Where Roof Flashing is Installed

Flashing is installed in various critical areas of the roof to prevent water intrusion:

Chimneys: Chimney flashing protects against water running down the chimney during rainstorms.
Vent Pipes: Flashing around vent pipes ensures that gases vent safely without water leakage.
Skylights: Skylight flashing kits prevent water from entering the home around these roof windows.

Roof Flashing Installation and Maintenance

At United Contracting & Roofing LLC, we recommend replacing roof flashing during a new roof installation to ensure a comprehensive waterproofing system. This approach helps avoid future leaks and extends the roof’s lifespan. While DIY repairs are possible, professional installation is advisable for safety and effectiveness.

Conclusion

Understanding and maintaining roof flashing is vital for the overall health of your roof. By addressing flashing issues promptly and ensuring professional installation, you can protect your building from water damage and extend the lifespan of your roof.

Taking care of your roof may not seem fun, but catching problems early on could save you both time and money in the long run. Leaky roofs can cause damage within your walls and leave you and your family with headaches to fix the damage. Determining the cost for roof repair or replacement can depend on a variety of factors. Having a trusted professional assess the damage and prepare an estimate for you can save you time, money and stress in the long run!

The first question to ask when it comes to roof repair is how old is your roof? And have you ever had to repair sections of your roof before? Older roofs do tend to need more maintenance and care as they could be more prone to leaks.

The second thing to think about is if you have had any storms recently. Difficult weather and storms add a lot of wear and tear on your roof whether it’s a new roof or not. Hail and hard rain can cause extensive damage to your home.

Lastly, have you seen any bubbles in your ceilings? This can be the first visual sign that there is damage or a leak in your roof. At this point you don’t want to wait. Finding out the damage on your roof and getting it repaired could save you thousands of dollars in the future.
