Any form of roof leaking can be detrimental to your home. One of the areas where water can get in is where there is roof flashing. Even the slightest vulnerability in your flashing can result in an issue. It is critical to watch the flashing and look for imperfections. If you think there could be any issues, talk to a roofing expert to get a professional inspection.

What Is Roof Flashing?

Flashing is weather-resistant material used on certain areas of your roof to reinforce it so it does not leak. It is commonly a thin metal sheet made from copper, lead, steel, or aluminum. The most important factors are that the material resists moisture and withstands high winds. The sheets work to direct water away from vulnerable roof areas, including joists and roof penetrations where there is a break in the shingles. It usually overlaps the roofing material and is fastened in place. When water cannot pool or leak, it cannot get through your roof and do damage.

There are several places on your roof where flashing is beneficial:

  • Vents and pipes
  • Skylights
  • Eaves and rakes
  • Chimneys
  • Valleys
  • Roof-to-wall intersections

What Causes Damage to the Flashing?

Flashing is durable, but nothing lasts forever. Here are some of the things that can damage the material.


If you can see any of the flashing from the ground, take a look at it. If you notice any rust, you probably need to replace the flashing. Galvanized metals delay the onset of corrosion, but it will eventually happen.


Temperature extremes cause the flashing to expand and contract, deforming the material and creating opportunities for leaks. High winds, hail, and heavy snow can also displace or loosen the flashing. If you suspect roof damage after a storm, schedule an inspection with us.


You should also think about how old your roof is. If it is older and has some signs of damage and wear, you want a roofer to look at it. They will let you know if the flashing or other elements require roof repair or replacement.

Poor Installation

A poor installation lessens the effectiveness of any material and leaves your roof susceptible to damage from the elements. If you suspect this is the reason for your leaks, check your warranty and take action. At Loyalty Exterior Solutions, we guarantee all our work, so you never need to worry.

Settling Foundation

All homes settle, and the shifting action can warp and crack the flashing. This doesn’t happen overnight; settling is a slow process.

Signs You Need New Flashing

If you have a problem with your roof flashing, these signs will tell you that it is time to get help from a professional. Since water leaks are the most common consequence, you want to look for signs of this. Look inside your home for water drips or stains on the ceilings or walls. Peeling wallpaper or paint can also indicate a problem with your flashing. Also, once the moisture seeps in, spots of mildew and mold may appear.

Getting New Roofing Flashing

Once a professional determines that you need new roof flashing, you should not hesitate to have them complete the job. During the inspection process, our roofers will assess all the flashing and choose the best material for your roof.

On the day of the roof replacement or repair, they will shape and cut the flashing to ensure it fits the areas perfectly to prevent leaks. Once it is in place, they will put a sealant on to waterproof the flashing. There are different application techniques for the various roof structures. For example, step flashing is appropriate for vertical structures, and drip edges work best for rakes and eaves.

The installer will end with a quality check. This ensures that all of the flashing is properly in place so that water cannot penetrate it.
