The average lifespan of your roof can vary depending on the materials used. Asphalt shingles can last anywhere from 20 to 40 years, while copper, steel, and tile roofing can last upwards of 50 years. Since roofing tends to be long-lasting, it's not something that you will have to replace often, or in some cases ever. However, if you do find yourself need a new roof, there are a lot of things to consider. Here are a few things that you should keep in mind when it comes to roofing installation.
The cost of a new roof can vary greatly depending on the materials used, the size of your roof, and your roofing contractor. In terms of materials, asphalt shingles tend to be the most economical option. Asphalt roofing costs between $120 and $400 per 100 square feet. Slate, tile, and metal tend to be far more expensive. Slate roofing costs between $800 and $4,000 per 100 square feet. Tile ranges from $600 to $4,000 per 100 square feet. Metal can cost anywhere from $500 to $1,800 depending on what type of metal you choose.
Tear-Off Versus Overlay
In many areas you are allowed to add another layer of shingles over your existing roof; this is referred to as an overlay. While this can save money, it does not allow the roofer to see the condition of the underlying decking and flashing. A tear-off involves removing the entire roofing in order to see the condition underneath. In many areas, especially parts of the US with a lot of winter weather, a tear-off may be the best option. While new decking and flashing can add around $5,000 to the total cost, it will ensure that you won't run into problems down the road.
The Roofing Contractor
Another thing to consider when getting a new roof put into place is your contractor. Shopping around can help you find the right contractor for your home. Most roofing contractors are busiest in the late spring through early fall months. You will want to find a contractor who is licensed and bonded. Replacing your roofing also involves a lot of nails as well; after the roofing installation is complete you will want to make sure that your contractor uses magnets to remove the nails that may have dropped into your yard.
Roofing installation is a major home improvement project. The first thing you will want to consider is the cost: costs can vary depending on the size of your roof and the materials used. You will also need to consider whether an overlay or a tear-off works best for you. Shopping around for a roofing contractor is another thing you should consider when getting a new roof put on your home.
