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. The cheapest roofing material is asphalt shingles. They come in a variety of colors and styles. They are generally used for flat roofs. Another type of roofing material is the corrugated steel panel. These roofs are lightweight and thin, making them ideal for covering the roof of a frame house. They are also easy to install. Metal roofs are durable and are recommended for wet climates. They look good on any home. However, they are more expensive than wooden structures. They are also fire-resistant so that they can be used in public buildings.
Another roofing material is slate. This material is made from asbestos cement and is inexpensive. However, it is fragile and should not be used in windy weather. It also has poor thermal insulation. Whether you have a flat roof or a sagging deck, re-roofing can be a good option. It is a fast, affordable, and temporary solution for your roof. However, it does come with some disadvantages. The shingles used in re-roofing may last for a while. Another disadvantage is the cost of materials. The materials used in re-roofing can be less expensive than a new roof. However, the cost of materials can vary by the size of your home. If your house is high or sloped, the price of re-roofing will increase. Another disadvantage of re-roofing is the additional weight added to your roof. This weight can cause structural damage to your house. It can also trap heat, leading to premature deterioration of your shingles. The extra material can also make it difficult for wet elements to get into your home.
