How (Not) To DO A ROOF VENT INSTALLATION
What NOT To Do
- Do NOT install onto the roof sheeting (meaning under the felt paper, and shingled into) because this will create a funnel for water to enter the roof.
- If installed incorrectly, do NOT try to seal it simply by caulking around it because water will leak through.
How To Remove An Old Vent And Do a New a Roof Installation Correctly!
1. Loosen the Edges of the Shingles Around the Vent to Be Replaced
Three-tab shingles are very hard not to break, but if you keep your flat bar flush and slowly pry, you might be able to save them. It is time-consuming. Also, have an extra bundle of new shingles, just in case.
2. Expose Nails, Slow Pry & Repeat (Until finished)
After the edges get loosened, the nails are exposed. You can pry them out by working from the bottom shingle up. Slowly pry the shingles and nails out and repeat until you’ve removed all the shingles necessary to remove the old vent and reinstall a new one.
3. Find The Source Of The Issue And Cut Out Old Vent If Needed
When you have all the shingles out, you’ll be able to see the source of the problem. You may need to cut out the vent.
4. Caulk The Felt Down To The Roof To Create A Seal
Caulk all the felt down around the hole you’ve cut to create a seal. Nail down the new vent.
5. Nail Down The New Vent And Caulk Again
After the vent is nailed down, caulk along the edges to create a waterproof seal. Then, continue to caulk, follow the shingles back up on both sides of the vent in a stair-stepping pattern. During this process, make sure to be conscious of any nail holes. If there are any holes, put the nails back in and then caulk over the top or caulk over the top of the hole and then nail the shingle back in.
6. Cut Shingles, Slide Them In, And Nail Them Down!
Quick tip: When cutting new shingles to fit the old ones, instead of cutting it from the top, flip it over and line it up with the old marking. Mark it with your knife, pull it aside, give it a cut, flip it over, and it will match perfectly.
