How Proper Flashing Protects Windows in Rainy Maryland Weather

Why Window Flashing Is More Than Just A Thin Strip Of Metal

Flashing is the layer that helps direct water away from the rough opening, the framing, and the seams where a window meets the wall.

That matters in Maryland because rain does not always fall straight down.

The principle is straightforward, even if the details are not. The window handles the direct exposure, while flashing protects the hidden layers that matter most.

An experienced company can confirm the cause with a quick inspection.

That is especially important on older homes, where framing may not be perfectly straight and previous repairs may have left a patchwork of caulk, tape, and trim.

Window contractors who know the region also think about exposure, roof runoff, siding type, and how the wall was built.
