Rain and snow can deteriorate the structural integrity of your roof over time. Without quality roof flashing, you could end up spending thousands of dollars on frequent roof decking replacements and repairs.
So what is roof flashing, and how does it protect your home? Our top-rated contractors serving Bloomington-Normal, IL, and surrounding cities explain what you need to know about flashing on your roof.
Why waste time and money on your roof replacements with unreliable contractors? Contact the local roofing experts at Sundown Exteriors if you have a problem with your roof’s flashing.
What Is Roof Flashing?
Roof flashing is a thin metal material that prevents water from seeping into cracks or gaps on your roof. Typically, flashing is made of weather-resistant products like galvanized steel or copper. Flashings have smooth surfaces that allow water to flow off drip edges and into gutters.
For most roofs, contractors install roof flashings behind shingles and siding and around chimneys and roof seams. However, for metal roofs, technicians usually place these materials on top of the metal roof panels for the best water resistance.
Which Roof Features Require Flashing?
Roof flashing safeguards the following features of roofing systems:
Excess moisture can weaken your chimneys. Durable flashing will extend the lifespan of these structures, so you don’t spend money on frequent repairs. The metal flashing seals any cracks or holes that may be present at the base of the chimney where it connects to the roof.
Your roof probably has at least one peak that creates a valley between two slopes of your roof. These valleys are vulnerable to water penetration. Without the proper protection, water damage can destroy the underlying decking. Aluminum flashings can fortify the valleys of your roof to improve the roof’s overall durability.
Some roofs have ventilation ports and pipes that are susceptible to leaks during storms. Flashing works to seal open gaps that may collect water.
Sealing your roof can also prevent insects and animals from entering the attic through cracks and openings.
Roof drip edges protect your home’s siding and fascia from water flowing down the property. Unlike asphalt shingles, metal flashings will not break or deteriorate from erosion.

Common Types of Roof Flashing
Here are some of the most common flashing strategies professional roofers use:
Contractors may install a single piece of flashing where the roof meets a vertical wall. These waterproofing solutions use gravity to direct the moisture down into the gutter.
Some homes may require expansion joints to keep the single layer of flashing from breaking or wrapping over time.
Roofers can secure base flashings at the bottom of vents and chimneys. These installations have two layers of metal that expand and contract with the roof during weather changes. Flexibility prevents the flashing from damaging roof materials.
Generally, you can expect a modern skylight to come with flashing around its weather seals and frame. In some cases, you may need to purchase the flashing separately. Without it, water can leak into your home through small gaps.
In some cases, multiple layers of flashing may be necessary to keep water away from vertical walls. Rectangular step flashing directs the stream down the shingles and off the property.
When to Replace Flashing
Do you need to replace your flashing every time you pay for a roof repair?
Your local roofing contractor can inspect your property to determine if new flashing is necessary. In most cases, these materials can last 20 to 35 years with the proper upkeep.
Certain home improvements, such as upgrading a roof from a three-tab shingle to a dimensional shingle design, will require new flashings. Otherwise, replacements may only be practical if the contractor finds any holes or rust on the metal. These problems can prevent the steady flow of water off your property.
Invest in an annual roof inspection to keep an eye on your roof flashing. This way, you can address problems before they escalate.
