Charleston Roofing: Article About Roof Replacement Costs
A good roof installed by professional contractors should last for 15 to 20 years or even longer. The amount of time the roof lasts depends on the materials used, with metal and ceramic roofs lasting longer than those featuring asphalt or composition shingles. Depending on the condition of the roof, contractors may determine that repairs are not enough and that the roof needs replacing. Homeowners should contact a Charleston roofing company, which will then send a contractor to their home and have that person check the roof's condition and other factors before giving an estimate for replacement.
One factor that determines the replacement cost is the size of the roof. Contractors will need to measure the total square footage of the roof and use that measurement to determine the number of "squares" needed to cover the roof. Shingle manufacturers sell shingles by squares and not square footage. A roof measuring 100 square feet might need 25 or more squares of shingles. If the home has any unusual slopes or valleys that change the overall square footage, they may need to spend more on both materials and labor for replacing the roof.

The cost can also vary based on the amount of work required. If the home has an aluminum gutter system with rusting downspouts and gutters, contractors may replace each downspout and gutter, which will add to the cost. Other factors that can impact the cost include the replacement of flashing, eaves, underlayment and decking. Each component of the roof that needs replacing will add to the cost. After performing a thorough inspection of the roof, contractors will often give homeowners an itemized list that shows them everything they need fixed or replaced and how much each of those jobs will cost.
Homeowners should also keep in mind that the cost varies based on the materials they choose. While asphalt, composite and fiberglass shingles are fairly inexpensive, those materials may only last between 10 and 20 years. Metal, slate and ceramic tiles are more expensive but will be able to last for 25 to 50 years or longer. Some manufacturers charge more but include a lifetime warranty that remains in place as long as the house stands. Other types of shingles include those made from wood or recycled materials. Local roofing companies can give homeowners advice regarding shingles and talk with them about the pros and cons of each material when replacing a whole roof.
