Working on top of roofs is considered a hazardous task for good reason.
When you decide to climb to the top of a roof for any type or re-roof you must keep in mind the various things that can put you at risk such as:
The roof’s surface: does your roof have an uneven or slippery surface?
Roof stability: Is the roof capable of sustaining your weight?
A loose ladder: always make sure your ladder is secured before climbing to a roof and, if possible, ask someone to hold it for you.
The pitch of the roof: steep roofs are known to let water and ice slip off, but they can also make you slip if you’re not careful.
Dangerous substances: watch out for substances like asbestos, paint fumes or other dangerous chemicals.
The weather: has it been snowing or raining lately? A wet roof significantly increases the chances of a slip and fall from the roof while performing a the work.
All of this increases the chance of falling from the roof dramatically during a residential re-roofing project and is the reason why insurance is a must-have when hiring a roof contractor for a residential re-roof.
In order to reduce these risks it is necessary to take certain precautions such as using ropes, harnesses and most importantly setting anchor points. These anchor points when used along with harnesses are the most recommended precautions as they can reduce the risk of falling almost completely.
The most common methods for attaching anchor points are:
By using a sling
One of the ways to secure anchor points is by simply tying a rope to an object like a tree, a car or a lamppost that is located at the opposite side of the home from where the worker will attempt to work on the residential rof, letting the object act as a provisional anchor point.
However, when choosing this method to install anchor points, it is important to make sure that the rope is tightly secured and that the object is able to resist the extra weight, avoid tying the rope to places that are unable to handle too much weight such as window frames or car wheels as these are usually not able to handle heavy weights.
Surface mount anchor point
These anchor points are used for residential re-roofing on metal roofs and are considered to be the easiest to install as the installation simply requires to attach the anchor points to the roof by using screws.
