Installing a steel roof ridge cap is a crucial step in ensuring the integrity and longevity of your roof. The ridge cap is typically made of steel and is designed to cover the peak of the roof, protecting it from water and weather damage.

A well-installed ridge cap can last for decades, but a poorly installed one can lead to costly repairs. It's essential to follow the correct installation process to ensure a watertight seal.

The installation process involves cutting the ridge cap to size, overlapping the edges, and securing it with screws or rivets. The correct overlap is typically 2-3 inches, depending on the manufacturer's specifications.

A good rule of thumb is to install the ridge cap in the same weather conditions as the rest of the roof, to ensure a consistent finish. This will also help to prevent any potential issues with the seal.

Preparation and Safety

Safety should always be your top priority when working on a roof. Ensure you have a sturdy ladder and wear a safety harness to prevent falls. It’s also advisable to work with a partner who can assist you and provide additional safety oversight.

To avoid accidents, always inspect your ladder before use and make sure it's securely positioned on a firm surface. This will give you peace of mind and allow you to focus on the task at hand.

A good safety harness can be a lifesaver, so don't skimp on this essential piece of equipment. Consider investing in a high-quality harness that's specifically designed for roofing work.

If you're unsure about any aspect of safety, consult the manufacturer's instructions or seek advice from a professional roofer. They can provide valuable insights and help you stay safe on the job.

Tools and Supplies Needed

To get started with steel roof ridge cap installation, you'll need the right tools and supplies. Here's a rundown of what you'll need:

You'll need cutting snips to trim the ridge cap to size. A carpenter's pencil is also a must-have for marking the cap's position on the roof.

A good pair of roofing gloves is essential to protect your hands from sharp edges. Make sure they're cut-resistant for added safety.

A caulking gun will come in handy for applying silicone sealant, which we recommend using Ultra 1000 for its quality and reliability.

Metal to metal screws with sealing washers will be used to secure the ridge cap in place.

To determine how many pieces of ridge cap you'll need, measure your roof carefully, accounting for a 6" overlap and 1" to prepare the cap ends.

Here's a list of the tools and supplies you'll need:

  1. Cutting snips
  2. Carpenter's pencil
  3. Roofing gloves (cut-resistant)
  4. Caulking gun
  5. Silicone sealant (Ultra 1000 recommended)
  6. Metal to metal screws with sealing washer

Installation Guide

Before you start installing a steel roof ridge cap, it's essential to read the manufacturer's installation guide. This will ensure you're aware of the specific requirements for your particular product.

Always check local building code requirements to ensure compliance. You wouldn't want to run into any issues down the line.

To begin the installation process, gather all the necessary tools. This includes a drill and drill bits, a tape measure, a chalk line, a circular saw, a pencil or sharpie, metal snips, and a pop rivet gun.

Cutting and Finishing Ends

Cutting and finishing the ends of a steel roof ridge cap can be a bit tricky, but don't worry, I've got you covered.

To start, make a one-inch mark on the outside of the ridge cap. Then, use a screwdriver to pry open both hems within the one-inch mark, and cut away one inch of the hem on both sides.

Next, line up your speed square to the exact pitch of your roof and mark a straight line. The angle of the line is determined by using a protractor, but unfortunately, it's not something that can be easily described in words, so I recommend watching a video for a better understanding.

To mark the center of the ridge cap, use the angle of the protractor as a guide. After that, cut the ridge cap, and then use a hand seamer to fold the uncut left side 90 degrees and the cut right side down 90 degrees.

If you're using a vented ridge cap, you'll want to skip the foam closure strips and move on to installing a ridge vent like ProfileVent. This will give you a 2-inch wide opening at the ridge for ventilation. Install ProfileVent ½” to 1” up-slope from the edge of the ridge cap.

Here's a quick reference guide to help you keep track of the steps:

  1. Make a one-inch mark on the outside of the ridge cap.
  2. Use a screwdriver to pry open both hems within the one-inch mark.
  3. Cut away one inch of the hem on both sides.
  4. Line up your speed square to the exact pitch of your roof and mark a straight line.
  5. Mark the center of the ridge cap based upon the angle of the protractor.
  6. Cut the ridge cap.
  7. Use a hand seamer to fold the uncut left side 90 degrees and the cut right side down 90 degrees.

Installation Steps

Before you start installing your steel roof ridge cap, it's essential to read the manufacturer's installation guide and ensure you're in compliance with local building code requirements.

You'll need to gather all the necessary tools for the job, including a drill and drill bits, a tape measure, a chalk line, a circular saw, a pencil or sharpie, metal snips, and a pop rivet gun.

To fasten the ridge cap, start by putting the first piece in place, and then fasten it with metal-to-metal fasteners at 12-inch intervals, making sure to fasten through the high seam of the metal roofing panel.

Overlap the ridge cap by six inches, with the laps facing the opposite direction of the sight line, and apply silicone sealant 2 inches from the inside overlap. Don't leave the cut edge of the ridge cap exposed.

Here's a summary of the tools you'll need:

  • Drill & Drill Bits
  • Tape measure
  • Chalk line
  • Circular saw
  • Pencil or sharpie
  • Metal Snips
  • Pop Rivet Gun

To secure each shingle, continue placing the next ridge cap shingle so that it overlaps the first one by about half an inch, and secure it with nails in the same manner, ensuring each shingle is aligned with your chalk line and properly overlapped.

To place the ridge cap, apply adhesive, carefully place the ridge cap on top of the adhesive, and press down firmly to ensure good adhesion. If necessary, use a rubber mallet or a block of wood to gently tap the ridge cap into place.

Secure

To secure the ridge cap, use screws or nails specifically designed for use with metal roofing.

It's essential to place the fasteners along the edges of the ridge cap, not in the middle, to ensure a secure hold.

Be careful not to over-tighten the fasteners, as this can damage the ridge cap or the underlying roof.

Using enough fasteners is crucial to ensure the ridge cap is securely attached, but don't overdo it – just the right amount will do.

A standard metal roof ridge cap is typically 7"X7" or 10"X10" wide.

How do you overlap a metal roof ridge cap?

To overlap a metal roof ridge cap, lap each piece by about 6 inches, starting with a ½ inch overhang over the gable trim. This pattern continues down the length of the peak, securing each piece with screws through the gable trim's flange.

How do you seal a ridge cap on a metal roof?

To seal a ridge cap on a metal roof, apply a high-quality sealant along the edges, covering screws or nails, and smooth it out for a watertight seal. Allow the sealant to dry completely before proceeding.

How do I stop my ridge cap from leaking?

To stop a ridge cap from leaking, replace missing nails or use roof sealant to seal gaps. Proper installation and maintenance can also prevent future leaks.

Where to put screws on metal ridge cap?

Place screws on each side of the metal ridge cap ends, in line with and penetrating the foam closures. This ensures a secure and watertight seal.
