When looking for a roofing company you need to try and find one that is reliable and that know exactly what they are doing. You may be approached on your doorstep from time to time by someone who asks if you have any roofing work that needs doing. Sometimes these people work for a larger organisation and other times they are self-employed. IT is up to you to check that they have the experience necessary to carry out any roofing job you give them. Never agree and pay any money on the doorstep, always ask for a quote and then give yourself time to do some research before agreeing. If they are part of a company, you should be able to find a website for them or possibly social media profiles. These will often have reviews on. You could also ask on any of the social media local groups to see if anyone has used them before. If you are in doubt then it may be better to go to a company that you know have a good reputation. Sometimes people use someone that they have never heard of before and then after the work is done, if a problem develops, they have no way of getting back in touch with them to ask them to come and rectify it.
