Using a ladder to access a roof.

For a small roof access hatch such as the bilco e 50tb which has internal dimensions of 915mm x 915mm a fixed vertical ladder should be specified. Residential roofers will most often use a combination of different ladders to install shingles or complete other roofing tasks. You will have difficulties to place and secure the ladder on the roof. This could damage the gutter.

This is prevents sliding of the legs of the ladder. Also known as cat ladders roof access ladders provide additional safety for those looking to conduct rooftop activities such as dedicated roofers and tv aerial satellite installers. The main issue with the ladder and the roof comes up is the surface is sloped or steep. What can be done instead is to ask someone to hold the ladder securely as you climb back on the ladder.

An easy way to figure the angle is to use a 1 4 ratio. You want the ladder to be at least 3 feet higher than your roof line. In other words for every 4 feet of ladder you need to move the base out 1 foot from the house. The key feature that differentiates a roof ladder from a standard ladder is the presence of a hooked end at the very top.

The companionway ladder is a 75 degree angled rigid ladder which provides permanent access to a roof hatch of up to 2440mm. Posted on september 14 2020 by miriam wheeler. Also make sure not to use the gutter as a support as you climb back on the roof.
