Flashing’s basic purpose is to prevent moisture intrusion into a wall or roof area at points where two pieces of materials come together and there are transitions between materials. Common areas for flashing are at doors, windows and chimney areas.
Common issues with flashings include:
- Getting bent or damaged
- Not being installed or installed properly
- Caulking or sealant in flashing areas needing maintenance
Not all flashing is metal
The majority of flashing is metal, but it may also be plastic, fiberglass or other materials.
Solving Flashing issues
The majority of flashing issues can be relatively easy to solve or repair, depending on what the issue is. However, if there is no flashing or it has been installed improperly, then the fix can be more difficult. If there is no moisture issue, then owners may not do anything about missing or improper flashing.
Caulking or sealing
Many flashing issues are resolved by adding a caulking or sealant to the area in order to compensate for the lack of flashing. At other times the existing caulking has deteriorated over time and needs to be re-caulked.
Who to consult? Siding contractor or qualified handyman.
Home owners and handymen often do limited maintenance and repairs on a homes flashing. Siding contractors are the most proficient in making repairs or changing the siding it-self. Occasionally a sheet metal contractor can repair or replace deteriorated or bent flashing.
