The tallest roof line of the roof you re working on is what you will base your ladder height on.
How much taller should a ladder be than your roof.
A straight ladder usually has a reach of two feet higher than the ladder s height.
To secure the extending roof ladder a pair of roof hooks should be installed onto the ladder.
They must lean against a stable support surface.
The sections must overlap at least 3 feet on ladders up to 36 feet in length and as much as 5 feet on longer ladders.
So if you don t need to reach a height of more than 12 feet than an 8 feet step ladder will suffice.
This will allow enough length for proper setup overlap of ladder sections height restrictions of the highest standing level and where appropriate the extension of the ladder above the roof line.
You want an extension ladder that will extend past this height.
With a step ladder the maximum height you can reach height of the ladder 4 feet.
The highest safe standing level is four rungs from the top of the ladder.
Straight ladders are tall ladders that are not self supporting.
For example if the tallest portion of a home you re working on is 25 feet you need a taller ladder than just a 25 foot ladder.
A roofing ladder is simply an extension ladder that has been securely attached to the ridge of a sloped roof to allow a roofer to work from an angle though no more than 75 degrees on the roof.
Typically these ladders are best for outdoor projects such as exterior painting or reaching your home s roof.
