Are your roof shingles looking shabby? Installing a new roof is a home improvement project many homeowners eventually face. How much to expect in cost for a new roof depends on several factors, and you can plug in the details of your situation and estimate an approximate new roof cost by considering the points described below.
Roofing Material Affects New Roof Cost
Two types of asphalt shingles are used in roofing: 3-tab shingles and architectural shingles, also known as dimensional or laminate shingles.
The 3-tab asphalt shingle has three, square tabs of the same size and thickness at the down-slope edge which have a flat look when installed. These shingles weigh less than architectural shingles because they are slightly thinner, making them less durable and more prone to curling over time.
Most 3-tab asphalt shingles have a 20 to 25 year life-expectancy, and they are the more economical roofing material of the two types.
Architectural asphalt shingles come in many designs and colors, but the main feature is varying shingle width and thickness, which adds more dimension and an extra element of aesthetic flair to the finished roof. They also cost more to install than 3-tab shingles.
Architectural shingles have a 30 year to life-time warranty and cost between $16 and $25 more for materials than 3-tab shingles for every 100 square feet of covered roof. This adds about $500 to $750 of materials cost to the entire price of the average new roof job.
Home Size and Design Affect Roofing Replacement Costs
The average residential roof is approximately 1,700 square feet, but your roof may be bigger or smaller. To calculate the approximate size of your roof, measure the overall outside width and length of your house to the edge of the eaves and multiply the two numbers to determine a rough estimate of your roof’s square footage.
Roofing is calculated in 100 foot squares. To figure out the approximate number of roofing squares in your roof, simply take the total square feet and divide by 100. For example, if your roof is 2,000 square feet, 2,000 divided by 100 equals 20 squares of roofing.
In most cases, a new roof costs between $350 to $500 per square, including materials and labor for installation. The removal of old roofing material can add an additional $100 or more per square. If the wood under the roof also needs replacement, costs increase as well.
Valleys and gables in a roof are where two slopes meet, and every valley and gable need a special layer of metal flashing. The more gables and valleys a roof has, the more expensive it is to replace.
Chimneys, vent pipes, and skylights also need a special metal flashing, affecting the cost. Each skylight or chimney can add between $150 and $200 to the total price of a new roof.
Steep roofs and multi-story buildings also add to the overall difficulty of a new roof, adding to the final cost.
Who You Hire Affects the Price of Your New Roof
