4 12 Vs 6 12 Roof Cost

Roof pitch is indicated by a number over a number.

4 12 vs 6 12 roof cost.

Medium slope 4 12 to 9 12 which are often mathematically reduced and expressed as 1 3 and 3 4. 2 12 pitch or lower low slope or nearly flat style roof. The higher the top number the steeper the pitch. Now assuming an average pitch of 9 12 we multiply the 2d area of 1 300 by 1 25.

6 12 pitch and up to 21 12 fairly steep to very very steep. The pitch of a roof the rise of the roof in inches over each foot of span horizontal travel. Additionally when you have a higher roof pitch the roof is seen so you might need to order a colored roof which add to your building cost as well. Standard roof pitches typically ranging between 1 12 and 5 12.

We had several reasons for going with a lower 5 12 pitch. I couldn t work on an 8 12 roof. Installing an asphalt roof on the same 1 500 square foot house with an average pitch of 6 12 will average 8 480 including the cost to remove the old roof. I suspect there will be more cost because of this more so than just more materials.

Common pitches are 3 12 4 12 5 12 6 12 and so on. You might have more waste with one pitch vs. It is still going to take 4 full sheets plus a rip to fill in. Let s say your 4 12 roof has a rake measurment of 16 7 and that rake measurement for a 6 12 roof was 17 4.

These roofs may require extra fasteners and these steeper roofs are very challenging to walk on. 5 12 pitch down to 2 12 moderately steep. A nice balance between water and snow run off and ease of access. A way of explaining this jargon would be.

The average cost for standard 3 tab shingles is 150 to 200 per square which last about 25 years. Steep slope any pitch above 9 12. Assuming this is a hip roof we multiply this by 1 1 which gives us roughly 18 squares or 1 800 square feet of the roof surface. Any roof pitch higher than a 5 12 requires custom engineering which might increase the cost of your building.

Roofs with pitches of 6 12 are the most common. Another and certain rake distance will obviously cause you to use more full sheets on the 6 12 pitch. This gives us a 3d roof area of 1 625 sq ft.
