Working Safely on a Roof: A Guide

Quck answer

Working safely on a roof is crucial to prevent accidents and injuries. Here are some key tips to follow:

1. Wear appropriate safety gear: Always wear a hard hat, safety harness, non-slip shoes, and protective eyewear.

2. Use proper equipment: Only use ladders, scaffolds, and fall protection systems that are in good condition and meet safety standards.

3. Check the weather: Avoid working on a roof during windy or rainy conditions as it can increase the risk of slipping or falling.

4. Clear the work area: Remove any debris or obstacles that may cause tripping hazards.

5. Use proper lifting techniques: Lift heavy materials with your legs, not your back, to avoid strain or injury.

Remember, safety should always be the top priority when working on a roof.


Most homeowners won’t have the need to go up on their roof. However, for those who do, whether it’s to fix a leak, make a small repair, or clear debris, it’s important to prioritize safety.

Some roofs are too steep and should be left to professionals. The same goes for tile and slate roofs, as they are easily damaged and can cause falls. If your roof is not too steep and has a safe walking surface, follow these guidelines.

Wait for the Right Conditions

Before climbing onto a roof, make sure the conditions are safe:

  • Even a small amount of morning dew can make shingles slippery, and strong gusts of wind can throw you off balance. So, wait for a dry and calm day.
  • Wear shoes with soft rubber soles for better traction.
  • Wear long pants made of thick fabric to protect your legs from the ceramic granules on the shingles and from the heat of the roof surface if you need to kneel.

Ladder Safety

Using a ladder is usually necessary to access the roof, so ensure you have the right equipment and know how to use it:

Safe Use of Ladders for Roof Work

  • Avoid placing ladders near power lines as accidental contact can lead to electrocution incidents.
  • All ladders, including step ladders, have a Duty Rating that specifies the maximum weight they can support. Do not carry any additional weight unless you are a professional roofer.
  • If tools are needed on the roof, use a rope to hoist them up in a bucket after safely reaching the roof.
  • For extension ladders, ensure that the top extension section overlaps the bottom section. Place the ladder on level ground away from the house’s wall, approximately one-quarter of the distance from the ground to the roof edge. The ladder should lean at a 75-degree angle.
  • Ensure the top of the ladder extends at least three feet above the edge of the roof. While it may be possible to climb onto the roof with the ladder slightly higher than the edge, it can be challenging on the way down. It is particularly difficult to get back onto the ladder in such a situation.
  • Brace or tie off the bottom of the ladder and consider placing warning barriers around it to keep others away while you work.
  • While climbing, keep your hips within the ladder’s rails and refrain from leaning out or reaching to the sides. Always maintain a grip on the rungs as you ascend or descend.

Up On the Roof

Once on the roof, it is crucial to follow common sense safety measures: remain aware of the roof’s edge at all times and avoid leaning over it.

  • Avoid walking on slippery surfaces such as pine needles, leaves, or other debris.
  • Store unused tools in a large container, like a 5-gallon bucket, to prevent them from becoming slipping hazards.
  • Be mindful of the location of extension cords, ropes, and other tools and materials to avoid tripping or slipping.

Safety Equipment

Professionals working on steep roofs utilize various safety devices, some of which can be purchased or rented by homeowners. Attaching safety equipment to the roof typically involves lifting the edge of shingles and securing the gear to the roof deck. Properly repairing the area after removing the safety equipment will prevent leaks.

Roof Safety Equipment

  • Roof brackets are used to support 2×6 lumber in an upright position. By placing these barriers a short distance away from the roof’s edge, they can effectively prevent falls and keep tools from rolling off the roof.
  • Personal fall arrest systems are comprised of a full-body harness, a method to secure the anchor to the roof trusses, a lifeline, and a shock absorbing lanyard. In the event of a fall, this system will halt the descent at a predetermined distance.

Working on a roof can be hazardous, but with a few precautionary measures, the task can be carried out safely and smoothly.
