Why Should You Reroof New Shingles Over Old Ones?
Many people choose to lay down new roof shingles over old ones in order to avoid ‘tear-off.’ The tear-off process is extremely messy as you have to get rid of your old roof in order to set the new one. Re-roofing shingles is a convenient way to skip the mess and additional costs. However, re-roofing also requires some prep work, such as the removal of vents and ridge caps. So, while re-roofing might seem like a good idea at first, you also need to consider the costs that might come later on. For instance, if your roof suffers any damage, you will have to tear down two layers of shingles to install a new one.
