As the name suggests, re-roofing your home means removing the Roof, either because it past its date of use or for aesthetic purposes. It is accomplished by adding a new one over the old one or removing old roof and replacing it with a new one.
Most common re-roofing materials and cost
Asphalt Shingles and Shingles of Composition Costs
One of the most common shingles are in North America, very popular in California and other dusty, hot areas of the United States. They are two options: fiberglass or architectural laminate.
Asphalt shingles and composition shingles have an estimated cost per square foot of $0.96 to $1.80 and $0.8 to $2.45 per square foot.
The Shingles of Wood and the Shake of Wood Costs
Cedarwood shingles are frequent, especially in rural areas. White Cedar, Red Cedar, Yellow Cedar, and Wood Shingles and Wood Shake are typically available to choose from Cedarwood shingles, particularly in rural areas.
The average cost of cedar wood shingles and wood shakes is between $1.80 to $3.15 per square foot.
Roofing Slate Tile Costs
Unfading green and purple, Variegated Purple, unfading grey, unfading black, unfading red, weathering black, weathering green.
Depending on your decision, expect to pay $3.80 to $13 per square foot for slate shingles. The replacement of one slate tile is about the $8 mark.
Recycled materials for the Roof
Reclaimed timber and composite plastics are most common. The average cost of these products per square foot varies very significantly. If you want to explore these materials, it’s best to get a custom cost estimate from us.
Roofing Clay Tile Costs
Here, your general choice is between color, type, and finish. Choose between tiles made of flat clay, mission tiles, or Spanish tiles, which come in several colors.
The average cost of clay tile shingles per square foot is $3.60 to $6.10 per square foot.
Concrete Tile Roofing Costs
Concrete tiles with an estimated price of $1.20 to $1.30 per square foot of material are a more cost-effective choice than fired natural clay. They come in a flat or corrugated finish, like gray, brown, red, green, blue, and black in several colors.
Advanced Roofing Tech Costs
Tesla’s solar roofing materials. It is touted that the cost per square foot, including installation, is as low as $21.85 per square
Roofing With Metals – Galvanized Steel and Aluminum Sheets Costs
The sheet comes in the corrugated or ribbed finish form; the price per square foot varies between $1.10 to $4.10, depending on the thickness and color. The per square foot cost of galvanized steel varies from $1.80 to $3.20 with installation.

Re-roofing Materials and Characteristics
In addition, styles of roofs also are in a variety of materials. Some weighty roofs require reinforcement of the deck, while others may need specialty labor. Your material will be a significant driving force behind the total cost combined with your Roof’s pitch and shape.
Roofing Materials Pros and Cons
|Asphalt||Common Lots of choices fast and easy to fix Lasts 15 to 18 years||May not be durable May be damaged by high winds|
|Architectural shingles||Very durable Resist impact better May resist UV rays Lasts 24 to 30 years||Moderately Expensive More difficult to fix|
|Clay tiles||Durable Many sizes and styles to choose from||Easily broken Difficult to fix and replace Expensive|
|Composite||Durable Can work in place of other roofing types and materials Lasts 35 to 50 years||Hard to find Difficult to fix|
|Metal tiles||Durable Can work in place of other tiles and materials Lasts 30 to 45 years||Heavy Expensive May be difficult to fix|
|Standing seam||Durable, light in weight, contemporary in style, lasts longer 30 to 45 years||Not a lot of style options May rust or leak easily|
|Slate||Durable Very Attractive Lasts upwards of 100 years||Heavy Expensive Difficult to fix|

Roof Replacement Cost
Note that you would have a choice to choose from when determining the cost of a re-roofing. Based on variables, contractors will estimate their cost, including:
- Scale Size
- Slope Complexity
- Current roof
- Type of material
- Underlayment and accessories
- Ventilation Flashing
- Job scope
- Size of project
Re-Roofing calculation (area, pitch, slope)
There is a form for any sort of roof: squares, rectangles, trapezoids and triangles, you can use our re-roofing calculator to make the calculations yourself. You need to multiply your roof length and width to get a rough approximation to measure the area of your re-roof.
Length x Width = Area
To find out the length and width, use a tape measure and then multiply the two numbers to obtain the area. By measuring one floor of your house, you can also get a rough measurement. If your home is roughly 1,200 square feet on a single level, your roof should also be about that square footage.
Calculate Slope & Pitch
The rise of the roof separated by the span (rise/span) is a pitch. To measure the pitch or slope, you don’t have to go on the roof. A pitch card is available from producers that you can use from the ground up. Roofs typically have one of three pitches, unless they are specifically built for a particular kind of home:
- Low pitch: Rises every 12 inches by 3 inches
- Medium pitch: rising every 12 inches from 6 to 9 inches
- High pitch: increases by 9 inches per 12 inches
You can come up with a rough approximation of the real area using the pitch table until you have the pitch or slope and the sum of all the sides. Once you have the pitch or slope and the sum of all of the sides, you can come up with a rough estimate of the actual area using the pitch table.
|3 in 12||1.04|
|4 in 12||1.06|
|5 in 12||1.08|
|6 in 12||1.12|
|7 in 12||1.16|
|8 in 12||1.20|
|9 in 12||1.25|
|10 in 12||1.30|
|11 in 12||1.36|
|12 in 12||1.42|
For example, if Roof is with a tape measure of 1,200 square feet with a pitch of 3/12, that means square footage is :
1,200 x 1.04 equals to 1,242 square foot.
