This is a question that many UK homeowners ask when confronted with a choice of roofing options, and there are major differences between reroofing and roof restoration, which we will explain in this article.
Reroofing involves laying a new set of shingles on top of the existing layer, which works out much cheaper than taking the shingles off and replacing them with a new set. Some minor repairs are normally carried out prior to laying the second layer of shingles, yet this does add considerable extra weight to the roof. Talking to the best roofing contractors in South Yorkshire would help you to decide whether or not reroofing in the best way to go. Once the job is complete, no one would even know that you have a double layer of shingles and the second set of shingles does improve insulation.
Restoring a roof means exactly that; carrying out the repairs necessary to restore the roof to its original condition. It might be more expensive that reroofing, but in most cases, it is the best long-term solution, and the roofing contractor would find matching shingles so that the repair will not look odd. Roof restoration can sometimes include replacing some of the interior timbers, especially if water has seeped into the roof, which can cause damage to the joists and rafters.
If your roof is in need of repair, talk to an established roofing company who will give you the options and advise you accordingly.
