We install step flashing against walls and other penetrations on a roof to prevent leaks. This flashing sheds water to the course below it so it does not need solder or sealant. For this reason, we fabricate step flashing from a pre-painted metal to prevent corrosion. Step flashings should extend at least 2 inches past the course above it to help water flow towards the gutters.

Counter and step flashing are often used together. Step flashing can be placed behind siding, while counter flashing cannot. Step flashing is used with any type of siding as long as you cover the top of it with another piece of cladding.

We install headwall flashing , also called apron flashing , where vertical walls intersect the roof. It prevents leaks by guiding water running down the wall onto the roof system. We place headwall flashing behind siding. If your house has a brick headwall, we install counter flashing to overlap the top of the headwall flashing. Deer Park Roofing prefabricates all headwall flashings from gauge steel in our shop to ensure consistency and performance.

There are many approved methods for valley installation. We find that the open no-cut valley method works the best. The first step in this method is to install an ice and water shield up the center of the valley. This is a self-adhering membrane that that adds an extra layer of protection to the roof.

On top of this, we install the metal valley liner. Next, we line shingles along the valley to prevent water from draining into the shingle courses. A shingle course is a row of shingles that directs water to the row beneath it. Every component of the roof, especially shingles, needs to point down to direct water to the gutters.

Below are examples of valley flashings. Place a small drop of caulk where the roof and chimney meet at the chimney corner. Place the step flashing over the caulk and onto the chimney. Hammer 2 roofing nails into the flashing and roof. Secure a shingle over the corner flashing using a hammer and roofing nail.

Place a second piece of 8-inch The flashing should partially overlap the shingle that covers the first piece of flashing. Secure a shingle over the second piece of flashing with a nail. Repeat the process until you have gone all the way around the chimney. Secure the chimney saddle.

Fit the chimney saddle around the back of the chimney. Use a hammer and roofing nails to attach the saddle to the roof. Insert roofing nails into the saddle and roof every 6 inches Place shingles over the flat part of the saddle.

Nail the shingles and saddle into the roof. Install the cap flashing. The grooves should be 1 inch 2. Saw as high as the height of the cap flashing. Fit the front cap flashing around the front of the chimney. Bend the cap flashing around the front of the chimney. Secure the cap flashing by inserting the flashing's flange all the way into the mortar. Drill a hole on each side of the chimney front. Hammer the plastic anchors into the holes. Repeat the procedure around each side of the chimney.

Ensure that each new piece of cap flashing overlaps the previous one. Place caulking along the mortar joints to seal the flashing. Can you measure and cut the sheet metal yourself or does it have to be ordered? Yes No. Not Helpful 6 Helpful For a chimney or skylight saddle, the larger piece goes at the top. If left as is, it could break or warp and fail to keep water out.

Therefore, long pieces have built-in expansion joints so they can move with the home. Base flashing : Some roof features, such as chimneys, require two pieces of flashing.

This ensures that rain always meets a flashing surface that directs it downwards. Plus, it is notoriously tough to install flashing around a chimney. There is another benefit to two-part flashing: When the roof materials naturally expand and contract with weather changes, the two pieces can move, so the whole system stays secure.

The base flashing or apron flashing is the bottom piece. Counter -flashing: Placed opposite to base flashing, or above base flashing, counter-flashing completes the two-part team. Step flashing : Step flashing is a rectangular piece of flashing bent 90 degrees in the center.

It is used for roof to wall flashing. Multiple pieces of the flashing will be installed in layers with shingles to ensure the water flows away from the wall.

Skylight flashing : While some skylight manufacturers include flashing in their products, sometimes roofing professionals have to create it or purchase it separately. Valley flashing : Open valleys have metal flashing to protect this critical area of the roof.

Drip edges : The edge of the roof has thin metal flashing that helps water drip off the roof without damaging the home or causing a leak. Kickout flashing : Roofing professionals need something to bridge the gap between where step flashing ends and the gutter begins.

Kickout flashing directs water away from the wall and into the gutter. Learn how to install kickout flashing below. Roof Flashing Materials In the past, roofing professionals would use lead, or lead-coated materials, as flashing. However, roofing professionals in North America now prefer other materials: Aluminum : Aluminum flashing is easy for roofing professionals to form and is lightweight.

However, aluminum must be coated if it is to be used with concrete and masonry, as plain aluminum reacts and degrades when it touches alkaline surfaces. In coastal areas, aluminum flashing should be coated even if it does not contact concrete or masonry, to prevent corrosion.

Copper : Copper roof flashing is also malleable and takes soldering well. On the other hand, it does discolor into a patina, which some homeowners dislike, but others favor.

You will still routinely find copper flashing around chimneys. Steel : Steel is usually the material of choice for flashing. In fact, if you live in Florida, you may find that your building codes call for a special flashing material, modified bitumen roofing tape: Modified bitumen roofing tape : Modified bitumen is a watertight, tough material. When made into a tape, it can be used to aid roof flashing.

The specific tape you use will have to be approved by your building code and of a certain width. Roof Flashing Sealant Types When you install roof flashing, you will need to use a sealant. Roof Flashing Techniques Before you learn how to install roof flashing, you need to understand that there are three primary techniques, each suitable for different areas on the roof. Step flashing : Step flashing is best for where the roof face meets a wall, for example, where a dormer projects out of the roof.

Step flashing ensures that water is directed away from the wall and ends up in the gutter. Counter-flashing : Counter-flashing is often used to flash chimneys. It involves two pieces of flashing. The first, base flashing, sits around the bottom of the chimney. The second piece, the counter-flashing, is embedded into the masonry of the chimney.

Construction professionals use counter-flashing for many other purposes, but it always involves a second piece of flashing set off from the first. Plumbing vent boot flashing : Vent flashing is a cylindrical piece of flashing that fits right around the vent. The shingles are installed over the base or boot. The height of the boot forces water to run around the vent.

How to Install Roof Flashing Disclaimer : Roof flashing should always be installed by professional roofers, who understand best practices, safety requirements and the building codes and laws in their area. How to Install Step Flashing With a Wall Corner If a wall corner is on the rooftop, you will need to create a corner flashing piece using a typical step flashing piece.

These instructions will tell you how to create a corner piece and how to install step flashing generally: Step One : Install your underlayment completely and your shingles up to where the wall begins, so that the first piece of flashing, or the corner flashing, will rest on a shingle.

Step Two : To make corner flashing, take your tin snips and cut a degree line from an outside corner to the center fold. Then, cut along the center fold and remove the resulting triangle.

This will allow you to bend the step flashing around the corner cleanly.
