The shingles will be replaced with a new layer during the re-roofing process. There are a few things to remember while performing the re-roofing process. These include the cost of materials, removing any traces of the old work, and laying a new layer of shingles. Adding a new layer of shingles when re-roofing is a convenient way to protect your roof. It also eliminates the messy tear-off process. However, there are some things to watch out for. First, make sure your roof sheathing is in good condition. It won’t protect your roof deck from water or ice if it’s in poor condition. Also, if it’s rotted, it could cause leaks, which could cause further damage. You may also want to use an ice and water shield, a rubbery moisture membrane, to prevent ice dams. Next, use building paper between your roof sheathing and the new shingles. It helps prevent water from getting under the new shingles and damaging your home. Also, make sure the roofing nails reach your sheathing. If they don’t, the shingles can blow off.
Adding an extra layer of shingles can also add weight to your roof, which can stress your roof structure. This excess weight can also cause your roof to sag between the rafters. It could result in severe damage, including rotting sheathing, insulation infiltration, and a shortened roof lifespan. Choosing a suitable roofing material can be a challenging task. In addition to technical features, the material’s cost should also be considered. Depending on the building type, the cost of roofing materials cost can vary significantly.
