Extension ladders give you safe, adjustable reach for gutters, siding, roofs, and high work areas on homes and jobsites. Built with sections that slide and lock, they offer tall working heights while storing compactly. Choose aluminum for lighter weight and easy transport, or fiberglass for non-conductive performance around electricity. Popular lengths run from 16 ft to 40 ft, with rope-and-pulley systems on longer models for smooth raising. Paired with stabilizers and levelers, they boost confidence on uneven ground and reduce wall damage.

Make a smart selection by focusing on:
- Height: For roof access, choose a ladder 7–10 ft longer than the support point so it can extend 3 ft above the roof edge and maintain a safe climb angle.
- Duty rating: Type III 200 lb, Type II 225 lb, Type I 250 lb, Type IA 300 lb, Type IAA 375 lb—match your weight plus tools.
- Material: Aluminum for lighter carry; fiberglass for electricians and outdoor work near power; both available with D-rungs for surer footing.
- Locks and shoes: Secure rung locks, interlocking rails, and non-slip swivel feet keep the ladder stable.
- Accessories: Stabilizer bars, levelers, ladder jacks, and hooks expand capability and comfort.
- Compliance: Look for ANSI A14 and OSHA-compliant designs for proven safety.

Use best practices every climb:
- Set at a 4:1 angle and on firm, level ground.
- Keep three points of contact and do not stand on the top three rungs.
- Tie off the ladder, avoid power lines, and inspect rails, rungs, and ropes before each use.
- Keep rails clean and dry; lubricate pulleys and store off the floor to prevent warping.

From painters and roofers to homeowners handling window cleaning, gutter maintenance, and roof inspections, extension ladders deliver reliable reach, portability, and jobsite efficiency.
