Ger To Attic Where Roof And Wall Meets

Chimney flashing a chimney is an area of the roof particularly vulnerable to water damage.

Ger to attic where roof and wall meets.

I can t really get my body close enough to the point where the hole needs to be to drop down the wall since the slope of the roof meets the ceiling in the attic and leaves only about a foot and a half clearance. Chimney flashing creates a water resistant shell around the chimney but flashing can be damaged resulting in leaks. They go along where walls meet the roof such as dormers etc. The short walls that meet the slope of an attic ceiling are usually referred to as knee walls.

You find these flashings where a roof climbs alongside a vertical wall. Headwall flashing should extend up behind the exterior wall covering and down over the roof covering material as you see here. If the roof wall connection isn t accessible from inside the attic and the inspection indicates that you have to add hardware you will need more than just a peephole. Part of the flashing turns up on the wall and the other portion gets covered by the next row of shingles.

In this spot it s possible that water could flow down the wall and slip past the shingles into the building below. This is true no matter what type of roof covering material is installed. This illustration shows proper flashing at a headwall condition. It is recommended to install ice shield on top of the smartvent extending up the wall about 12 to ensure a weather tight seal lapping under any house wrap so water can drain over the ice shield any waterproof membrane will work instead of ice shield.

A headwall is a level junction where a roof meets a wall. These low walls add an interesting architectural feature to. One way to gain access is to take up roof decking at the eaves as shown in figure 2. Look for rust or holes in these flashings.

The best way would be to install one or more layers of rigid foam above the roof sheathing followed by a layer of osb or plywood and new roofing. This approach would transform your vented unconditioned attic to an unvented conditioned attic. Step flashing is best for where the roof face meets a wall for example where a dormer projects out of the roof. This approach would also require you to insulate the gable walls of your attic if there are any.

As each row of shingles is laid a step flashing is installed over the shingle next to the wall.
