Roofs perform such an essential function that "keeping a roof over your head" is synonymous with the very concept of shelter. Roofs not only keep the rain off your head, they also keep moisture from destroying your home. So when it comes to maintaining your investment, the smartest money you spend could be on a new roof. How much you'll spend on replacing your roof will vary, depending on several factors. If you don't need a new roof, then you may want to read this guide on roof repair costs.

Size of Your House and Total Square Feet of the Roof

The single largest factor in the cost of your roof is, not surprisingly, the size of your home. The bigger the house, the bigger the roof, the larger the cost of both materials and labor. Most roofers charge by the square foot, with a number that encompasses both materials and labor. Most roofers can give you a ballpark estimate of the project cost based on your home's square footage. That makes comparison shopping for roofers fairly easy. If you have multiple floors, then the square footage of your roof will likely be influenced by the square footage of the largest floor and not the total square footage of all the floors. Your roofing contractor should be able to help you calculate these factors into the cost.

Height and Pitch of Your Roof

The higher your roof and the steeper the pitch, the more expensive your roof installation will be. With a steeper and taller roof, the installation is both more difficult and more dangerous, and it may take longer and cost more. Some roofers will quote you a general price based on the size of your home but will not guarantee that price until they see the height and pitch of your roof and whether you have any hard-to-reach spots.

Removing Old Shingles

If you're replacing the roof on your home with a new roof, your estimate might need to factor in the price of removing your old shingles. In some cases, you can save money by installing the new shingle over the old ones without removing them, but that's not always an option. A new roof installed over the old one can become too heavy for the structure of the house and is not always a good idea for every home. And if there are already multiple layers of shingles on the roof, not only is it a bad idea to install more shingles on top, but you may pay double the standard cost of removal.

Shingle Types and Quality

There are various types of roofing available to homeowners, depending on the climate conditions and what they're willing to pay. Asphalt and composite shingle roofing are the most affordable options for homeowners, which come in different designs and will be found on most homes as they blend well with siding.
Clay tiles work well with homes designed in the Spanish mission or Italian style, and they will last for a long time, as long as they don't break during installation. Slate tiles are also fragile and breakable when they're first being installed, but then they'll require little maintenance and last for an extensive amount of time against climate conditions. Wood shake is beautiful and natural, but it can be a serious hazard against fire.
Concrete or cement tiles can mimic the appearance of wood or ceramic tiles without being fragile or burning up during a fire. Metal roofing is one of the most expensive options out there, but it can go a lifetime of a home without needing to be replaced.
Within each of these types, you'll find different levels of quality and corresponding prices. It will almost always pay in the long run to splurge on the highest quality you can. It will last longer, protect your house better, and you might actually lower your insurance premiums. (Ask your agent.)

Gutter and Flashing Replacement

It may be a financially smart decision to pay extra for having your gutters and flashing installed or replaced along with your new roof. If your roofer is already doing the labor for the roof installation, the cost for gutter and flashing installation would be less than if you had them done at a later date all by themselves. So although your total costs will be higher, you will save money over doing the two jobs separately.
