Roofer Standing on Ladder Working on RoofSelecting a Good Ladder for Roof Work

If you’ve got a roofing project ahead of you, you’re only as prepared as the tools you have to work with. Not only does that mean the roofing materials, but it means the right ladders as well. With so many different kinds of ladders used by roofers such as step ladders, extension ladders, and even scaffolding walk boards in Lawrenceville, GA, choosing the right setup is important if you’re going to get the job done in a safe and timely manner. If you’re not sure what kind of ladder(s) is best for your job, here are some things to consider.


Ladder Types

There are several varieties of ladders, but there are a few basic categories that you should know.

•   Self-Supporting — These are ladders that stand on their own and form an A-frame. Stepladders are included in this category, as well as household ladders, and those with professional grades capable of supporting aluminum walk boards in Lawrenceville, GA.

•   Non-Supporting — Non-supporting ladders can’t stand on their own but have to be leaned up against something. Many of these are extension ladders.

•   Roofing Ladders — Roofing ladders are extension ladders that can secure themselves to the ridge of a roof so that you can work on a slope.


Ladder Length

When figuring on the required length you’ll need to get out of your ladder, don’t forget that the entire length isn’t usable. On an extension ladder, for instance, you can’t work beyond the last three feet. Working too close to the top can cause the ladder to become unbalanced, and therefore, unsafe. By giving yourself extra length, you’ll also be providing yourself with something to hold onto when getting off the ladder and onto your roof. Before settling on the length of an extension ladder, don’t forget to factor in the angle you can expect it to lean in order to reach the roof. To ensure stability, the ladder should be set back one foot from the building every four feet in height.


Duty Rating

Whichever ladder you choose, it’ll need to be strong enough to withstand the job. To determine the weight that a ladder can bear, you’ll need to know its duty rating. Roofing materials such as shingles can be heavy, and if a ladder doesn’t have the required duty rating, it can be unsafe. Here are the ratings set forth by the American National Standards Institute (ANSI):

•   Type III-Light Duty - 200 lbs., suitable for household use

•   Type II-Medium Duty - 225 lbs., suitable for light maintenance and handyman work

•   Type I-Heavy Duty - 250 lbs., suitable for tradesmen and many kinds of construction and industrial work

•   Type 1A-Extra Heavy Duty - 300 lbs., suitable almost entirely for industrial applications

•   Type 1AA - 375 lbs., only used for very heavy industrial work


When determining the weight that’s necessary for your job, don’t forget to add your own weight to the materials you’ll be carrying.
