Question: If some windows are missing flashing but not leaking, are we required to rectify this problem so the building is compliant?
We live in a complex of 4 townhouses, built in 2003. As the building code has changed over time, our windows no longer comply. There is no flashings on the windows and a few of the units have experienced rainwater coming inside. Is it a requirement that all windows have to be brought up to new code compliance?
Answer: If there are windows that you believe do not have flashing, but there are no water penetration issues, there is no compliance requirement to rectify the situation.
Good building practice would always have required flashing to be installed at the time of construction. While I don’t have the specific details of your building, flashings are typically independent of the window, as they are bricked in.
Cavity construction requires the installation of flashing above and below the window and it’s the failure of the head [above] flashing that typically is the cause of water penetration issues.
If there are windows that you believe do not have flashing, but there are no water penetration issues, there is no compliance requirement to rectify the situation.
