Why Step Flashings Matter
Before we jump into the nitty-gritty of installation, let’s talk about why step flashings are so important. Step flashings are thin pieces of metal (typically galvanized steel or aluminum) that are installed around roof penetrations such as chimneys, walls, or dormers. Their primary purpose is to create a watertight barrier between the roof and these vulnerable areas, preventing leaks and water damage.
How to Install Step Flashings: A Step-by-Step Guide
Materials Needed:
- Step flashing pieces
- Roofing nails or screws
- Roofing cement or sealant
- Hammer or screwdriver
- Roofing shingles or other roofing material
Steps:
- Prepare the Area: Clear away any debris and old flashing from the area where you’ll be installing the step flashings. Ensure the surface is clean and dry.
- Cut Flashing Pieces: Measure the area and cut the step flashing pieces to size using tin snips or aviation shears.
- Install the Bottom Piece: Slide the bottom piece of step flashing under the shingle or roofing material and over the edge of the wall or chimney. Nail it in place, leaving room for expansion.
- Install Wall or Chimney Counterflashing: Apply roofing cement or sealant along the top edge of the step flashing and press the counterflashing into place. Secure it with more nails or screws.
- Overlap Subsequent Pieces: Install the next piece of step flashing above the bottom piece, ensuring it overlaps by at least 2 inches. Nail it in place.
- Continue Layering: Repeat the process for each subsequent piece of step flashing until you reach the top of the area to be flashed.
- Seal Joints: Apply roofing cement or sealant over the top edge of each piece to seal the joints.
- Install Roofing Material: Install the rest of the roofing material over the flashing, ensuring it overlaps for further waterproofing.
- Inspect and Test: Inspect the flashing for proper installation and run water over the area to test for leaks.
