There are plenty of mistakes that people make with their roofing. They may choose the wrong type. They also choose the wrong contractor.
It is crucial to do your research on both the roof you want, and on the contractor that will install it. You can use online website such as AngiesList and Google to read reviews. Further, friends, family, and coworkers are all great sources on which contractors are good and which ones are not. In this video, you will see some people who are maybe a little less than experienced in the roofing business.
In this video, you will see a man dangling from a roof. He is holding on to the roof while the ladder is almost out of reach. It seems that the ladder was not properly secured before climbing up the roof. It is also important to have someone on the ground at all times to both hold the ladder and make sure that it does not fall down. Otherwise, you could be stranded on the roof.
Another clip shoes a roofer driving a pickup on the road. The roofing shingles were not properly tied down in this instance. This caused them to disperse all over the road once the vehicle picked up speed. This must have been embarrassing. Much of the roofing supplies likely also needed to be replaced.
