What Is Roof Flashing (And Why It Matters)?

Roof flashing is the protective metal (and related waterproof detailing) installed at roof joints and penetrations to direct water away. When flashing fails, water can get beneath roofing materials and cause interior leaks or hidden damage.

Flashing is commonly found at:

  • image
    Chimneys
  • image
    Roof valleys
  • image
    Plumbing vent pipes
  • image
    Skylights
  • image
    Dormers and roof-to-wall connections
  • image
    Step flashing at sidewalls

  • image
    Ceiling stains or water spots near chimneys or exterior walls
  • image
    Leaks during wind-driven rain
  • image
    Rusted, loose, or visibly lifted flashing
  • image
    Cracked or failing sealant around flashing areas
  • image
    Damp attic insulation near roof transitions
  • image
    Repeated leaks that return after “patch” work
  • image
    Water staining on brick near the chimney (sometimes flashing-related)

    Tony and his team absolutely crushed it. Pricing was great compared to other quotes I got. Job was swift they took care of everything. Every time Tony said his team would be there they showed up. I sent another roofing expert up to look at the work and he said everything was done with great care and good materials. Would definitely recommend for anyone looking to get a roof done.

    Tony and his crew at Done Rite Exteriors did an outstanding job installing our metal accent roof and matching gutters. He arrived right on schedule, completed the project efficiently, and delivered top-notch craftsmanship with perfect matching detail. They also did a fantastic job cleaning up the site afterward, leaving zero debris behind. If you need reliable quality and exceptional professionalism, I highly recommend Done Rite Exteriors!

    I had an excellent experience with Done Rite Roof Repair. They completely redid the siding and gutters on my home, including replacing and repairing the wood behind the siding where needed. Before the work was done, we were having water intrusion and leaks whenever it rained. Since the project was completed, everything has stayed completely dry, even through heavy rain, and the exterior looks fantastic. The quality of the workmanship and attention to detail really shows. Tony was my main point of contact throughout the entire process and was great to work with. He was responsive, knowledgeable, straightforward, and made sure everything was done properly from start to finish. It’s not always easy finding a contractor you can trust to do a major exterior project correctly, but I’m extremely happy with the result. I would absolutely recommend Tony and the Done Rite team to anyone looking for high-quality siding, gutter, or exterior work.
