Another safety measure that should be incorporated into any type of roofing work is that of firmly securing a ladder that will be placed on a dirt or grass surface. One of the best ways to secure this type of ladder arrangement is to simply dig holes to firmly hold the bottom portion of the ladder in place. Equally important is to always avoid walking on a roof when it is wet or icy. Even loose leaves can cause one to lose their footing and fall. Working on a roof is a serious matter and is a situation that must be treated with respect.
