Understanding Ladder Duty Ratings
ANSI duty ratings tell you how much weight a ladder can safely hold. Type III supports 200 pounds, Type II holds 225 pounds, and Type I rates for 250 pounds. Type IA models, like several ladders on this list, carry 300 pounds, covering a worker plus tools. Always add body weight to tools, materials, and clothing before choosing a rating.
Aluminum vs Fiberglass Rails
Aluminum ladders weigh less and cost less, making them popular for occasional home use. Fiberglass rails do not conduct electricity, which matters near power lines or electrical panels. Fiberglass models also resist UV damage better over years of outdoor storage. Weight is the tradeoff, since fiberglass rails add several pounds per section.
Sizing an Extension Ladder to Your Home
Extension ladders are sold by nominal closed length, not maximum reach. A proper setup needs the ladder to extend three feet above the roofline or gutter. Overlap between sections reduces usable length, so a 24-foot ladder typically reaches about 21 feet of working height. Measure your tallest gutter or roof edge before buying.
Extension Ladder Safety Basics
Set the base one foot away from the wall for every four feet of height. Footing should sit on firm, level ground, never on boxes or uneven surfaces. Both rails need to contact the support surface evenly at the top. Never stand on the top three rungs, and keep hips between the rails while climbing.
FAQs
How do I know what size extension ladder I need?
Measure the height to the roofline or gutter, then add about 3 feet so the ladder extends past that point. Account for overlap between sections, since a ladder's nominal length is longer than its working reach.
What is the difference between Type I, Type II, and Type IA ladders?
These letters and numbers refer to ANSI duty ratings. Type III holds 200 pounds, Type II holds 225 pounds, Type I holds 250 pounds, and Type IA holds 300 pounds, covering climber weight plus tools and materials.
Are fiberglass extension ladders worth the extra weight?
Fiberglass rails do not conduct electricity, which matters for anyone working near power lines, service panels, or wiring. The extra weight is a fair tradeoff for that safety margin, though aluminum stays lighter for occasional ground-level jobs.
How much does a 24-foot extension ladder weigh?
Aluminum 24-foot extension ladders typically weigh in the mid-30-pound range, while fiberglass versions of similar length can weigh 45 pounds or more due to the heavier rail material.
Can one person safely set up an extension ladder alone?
Yes, most aluminum extension ladders under 28 feet can be raised by one person using the fly-section rope and proper footing. Longer or fiberglass ladders are heavier and easier to manage with a second person.
What is the 4-to-1 rule for ladder placement?
The base should sit one foot away from the wall for every four feet of ladder height to the support point. This angle, close to 75 degrees, gives the safest balance of stability and climbing ease.
Do telescoping ladders work as well as traditional extension ladders?
Telescoping ladders like the Xtend+Climb NX1 collapse to a compact size for storage in a trunk or garage. They typically top out shorter than traditional extension ladders and cost more per foot of reach.
How often should an extension ladder be replaced?
Replace a ladder after any fall, visible crack, bent rail, or loose rung, regardless of age. With proper storage and no damage, aluminum and fiberglass ladders can remain safe for many years.
Is a 20-foot or 24-foot extension ladder better for a two-story house?
Most two-story homes need a 24-foot extension ladder to safely reach the roofline with three feet of extension above the gutter. A 20-foot ladder often falls short once overlap and required extension are factored in.
Our verdict
The Werner D1224-2 stands out as the best overall extension ladder for typical two-story homes, combining a solid duty rating with manageable weight. Buyers working near electrical lines should lean toward the fiberglass Louisville models, while budget shoppers and occasional users are well served by the Cosco or Ohuhu options. Match duty rating and length to your specific job before choosing.
