Installing flat roof ventilation can be a complicated process. Follow the steps below to install a ventilator on your flat roof.
Step 1 – Prepare
Choose the ventilation that you think is compatible with your roof. If you want the piping from your vent to go into the attic, drill a hole starting from the roof and out to the attic. Mark the area with a screw to keep it visible when you go cut out the hole on the roof. Be careful to avoid roof beams when cutting the hole.
Step 2 – Detach and Cut
After determining the location of the vent, remove the roof tiles in the area of the vent. Remove the tiles carefully to lessen the damage to other tiles, and keep those tiles that can be reused.
When cutting the hole for the vent pipe, leave some free space in case you want it to expand. Cut the hole from the center to the edge.
Step 3 – Install the Vent
Now, attach the venting hole and enclose it with the correct flashing. The use of flashing depends on the vent. There are those that do not need one. If you use flashing, secure it with nails. Make sure to check for possible areas that moisture may get through and use roofing tar to fill that gap.
Step 4 – Cover the Roof
Once you’re done installing the vent, reattach or replace the roofing tiles.
