Make sure your roof ladder is long enough.

What size ladder do i need to get on my roof. If your one story house is 10 feet high you need a straight ladder of 13 feet long and an extension ladder of 16 feet long to reach the roofline for multi use purposes in your one story house little giant ladder systems 12026 001 can be the best option for you. When considering how tall a ladder needs to be to reach a roof don t forget that useable height of a ladder is different than its actual height. It needs to be at least three rungs above the gutter. So assuming our measurements for the 2 floor house 6 m in height with a base of 1 5m we then need to use the pythagoras theorem to work out the ladder length.

The ladder should be at the correct angle with the base 1 foot out from the surface it rests against for every 4 feet of height to that point. Keep this in mind when calculating the minimum height the ladder must be to reach the roof. Ladder fully extended length will be fine for this job. For instance on an extension ladder you can only use up to the top three feet.

You need to square a and b to get c so 6 x 6 1 5 x 1 5 a b. You ll also need to give consideration to the overall length of the ladder and make sure that it is long enough to reach from the eaves to the roof ridge. 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. The length of ladder you need height of your house 3 a in this example.

So if you don t need to reach a height of more than 12 feet than an 8 feet step ladder will suffice. However if you need to reach 16 feet of height then you should go for a step ladder which is no less than 12 feet tall. The highest safe standing level is four rungs from the top of the ladder. Here s the calculation to determine the height of a step ladder.

Extension ladders should be 7 to 10 feet longer than the highest support or contact point which may be the wall or roof line. 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. Outside a taller stepladder multi purpose or extension ladder is often more appropriate for jobs requiring a reach of thirteen feet or more. 25 3 6 34 hence to reach to the eave of the roof which is 25 ft high 34 ft.

What does floor to floor height mean. If your ceiling is 12 feet in height subtract the four feet needed for the worker to reach the work area and the remainder would be the height of the step ladder needed in this case a 8 foot step ladder. Style when working indoors a stepstool stepladder platform or multi purpose ladder is usually recommended when you need a reach of two to eight feet.
