When it comes to roofs, quality trumps quantity. But is it really a good idea to add another layer? Probably not. Most roof installation companies would agree that adding an additional layer reduces the quality of the roofing material. Yet many homeowners have two or more layers. Here are some things to consider before you decide to add another layer. But before you make the decision, consult with a roofer or the local roof installation company and learn more about your options.

One factor to consider before installing a second layer of shingles is the weight. Adding a second layer will make it more difficult to detect damage. The extra weight of a new layer will accelerate the deterioration of the older shingle layer. And while the additional shingle layer will protect the home from the elements, it won’t last as long as the old one. And, inspectors tend to look negatively on roof-overs.

Another thing to consider is the appearance of the shingles. A layered roof looks great in photos, but a second layer of shingles will make the structure less durable. A double-layered roof can also make it more difficult to sell a home and may not pass a home inspection. Depending on your local building codes, you might want to consider complete roof stripping and re-shingling. This allows you to check the shingles and apply a fresh layer of felt to the decking. However, a second layer of shingles may be more cost-effective in the short-term.

One consideration is the cost of a roof over. There are many costs involved. Some roofs will need to be completely replaced, while others will only need a single layer. In either case, it is cheaper to

apply new shingles instead of having it installed. The cost of installing a roof-over is significantly higher than the cost of replacing the shingles. Likewise, some roofs will require a new one with more than one layer.

Another issue is that having a second layer of roofing can make it more difficult to spot any damage. Water that penetrates the first layer of roofing may travel quite a distance before reaching the second layer. A leak in the living room, for example, might have originated in a weak spot on the roof above the bedroom. This can complicate the diagnosis, leading to costly repair work and a lack of warranty coverage.

A second important consideration when deciding how many layers of roofing to install is the framing. Essentially, a roof is a triangular structure that supports the weight of the rest of the materials. It also provides the roof with protection against fires, which can damage the roof or the house. There are several layers underneath the roof, but they all serve a very specific purpose. By working together, they not only protect the home from the elements, but improve the comfort of the people who live underneath it.

A third consideration when deciding how many layers of roofing to use is the cost. A reroofing of 20 squares will likely cost $1,000 less than a tear-off. Not laying felt paper will cut down the cost by about ten dollars per square. In addition, you will save on weather protection and site protection.
However, the cost of this option is not for everyone. However, the savings you can get from reducing the number of layers is considerable.
