Installing the vent-a-ridge is basically about promoting good ventilation by allowing air to flow through your roof. This is done by creating a hole on the roof and covering it with a vent. Installation is a do-it-yourself project. But unlike some DIY projects, installing a vent-a-ridge vent is a pretty demanding task. Do this only if your carpentry skills are average or above average. Here’s how to go about the installation process.
- Prepare your materials and tools. Like any DIY project, the first thing you need to do is to gather all the materials and tools needed for the completion of the installation. You will need ridge vent, circular saw, claw hammer, nails, flat bar, chalk line, tape measure, shingles, and remodeling blade.
- Remove the shingles. Begin the process by first taking the shingles off the ridge cap. Shingles were installed either by cement or nails, so a flat bar is necessary. It is almost impossible not to damage them as you peel them off. So in case you are planning to use the shingles again on your ridge vent, be careful as you remove them.
- Mark the ridge board. The ridge board will be exposed when you remove the shingles. This is where you should make marking lines. Using chalk line, make two lines on both sides of your ridge board, following the manufacturer’s recommendation on the size of the opening. In any case, though, you can mark lines 7/8 of an inch from the start of the roof slope. To make a line, push the chalk line from one end of the ridge board all the way to the other end. Do the same thing to the other side of the ridge board.
- Make an opening. Now that you have created lines, you can start making a hole on the roof sheeting. But first make sure to wear goggles and dust mask to protect yourself from bits of wood. Now, run the circular saw along the lines you have created. It is best if you have your circular saw installed with remodeling blade, so you can cut through a part that may have nails. Also, remember to find out the thickness of the roof sheeting to avoid slicing through the rafter.
- Place the ridge vent. Cut the plastic vent according to the size of the hole. Depending on the length of your ridge cap, you might have to make several strips of vent. When you have already strips, begin nailing one strip to cover one section. Nail another one and make sure to connect it to the first section. Continue doing this until the entire hole is covered.
- Put shingles on the vent. Use your old shingles if they are still in good condition. Otherwise, buy new shingles to put on the ridge vent. Install the shingles one by one, beginning from one end, working your way to the other end.
This job should be carried out with at least one assistant. Never take this on alone unless you are very, very skilled. But remember: even professionals get an assistant to help them complete the job.
