Water Leaking From Roof Through Window

The leak can also happen at the frame of the window itself.

Water leaking from roof through window. 7 rarely a leak at an overlying window or vent or a roof leak or a leaking overhead water or hydronic steam heating pipe getting into the wall and running down into the wall till it hits the underlying window running down around the frame and leaking out at the the bottom sill. The water oozes into your house from every angle and crevice around the window from top to bottom. The culprit is often old or poorly done window sealant. These air channels will eventually cause water to come down through.

Water doesn t always come in at the shingled surface. Have a roofing expert conduct an inspection of your roof system. Use this material accurately to avoid window leaking. Begin soaking low on the roof just above where the leak is visible inside the house.

In this case you have a problematic window. Use enough water to mimic heavy rains. Run water over the low side of the penetration for several minutes while the helper watches for any water droplets. Missing shingles or a failing roof system might be your culprit.

If you notice water stains on the wall above the window or along the top or bottom of the frame this usually means there is a leak inside the walls. In milder cases of this type of leak you may only see water come in from a few spots such as the sides or the bottom. Dormer walls provide lots of spots where water can dribble down and enter the roof. Often the water will follow an unusual path along ceiling joists or wall studs until it reaches a window frame where it can then drip inside.

If a main roof or flashing leak running down and exiting at the window you should see water running down the underside of the sheathing and staining. The most common way of sealing windows today is with the use of expanding foam. If there s too little foam used there will be air channels between the window and the wall. Sometimes leaking water is finding its way into your through your window sills or frame but is actually coming from your roof.

The water will leak along the window and will pool either at the bottom or top part. If none there then that leaves you with the dormer roof and flashing the window itself or siding above the window which are more likely unless you have a flat topped dormer. Leaks can also occur when rainwater enters through the roof chimney or loose fitting siding.
