Person cutting hole in roof using jigsaw.

Overview

We show you how to install a manhole in your ceiling to give you access to the roof cavity. You'll see how to measure and cut the hole in the ceiling.  We also show you how to attach the frame for the access panel. 

Steps

1Mark out the position of your manhole

Decide where you want to put your manhole. Check there is room between the studs for the panel. Measure up your panel then use your pencil to mark the centre point on the ceiling. Now measure out and mark the edges of the panel on your ceiling.

2Cut a hole in the ceiling

Check in the roof to make sure there are no electrical wires that you could accidently cut into. Use the keyhole saw to cut a small hole at the centre point. Now use the reciprocating saw to cut around the marked edges.

3Secure the frame in place

Insert your manhole frame into the hole. Make sure it is nice and snug. Then drill a pilot hole through the frame into the timber roof beams. Use screws to secure the frame in place. Finish off by inserting the cover panel.
