To find your roof’s total square footage:
- Measure the length and width of each plane on the roof (including dormers) then multiply length times width.
- Add the square footage of each of the planes together.
How do I calculate roof covering area?
To calculate your roof area, simply multiply your roof length by your roof slope height, and multiply this by two. This should give you the total area of your roof, not accounting for a chimney or other sections of your roof not covered by tiles. Follow Us for more details Please!
How do you calculate rafter length?
If you are calculating rafter length from the center of the ridge beam (as shown below), you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1.5 inches thick, subtract 3/4 of an inch from the overall rafter length.
Estimate Roofing Costs
Measure the square meter area of the roof you want replaced. The range of prices to replace your roof is: $50 to $95 per square meter. So multiple this rate against the square meter of the roof you want replaced.
Average Cost to Replace a Roof
| House (& Roof**) by Square Foot | Re-Roofing Cost* |
|---|---|
| 1,000 (1,054) | $4,000 – $5,500 |
| 1,100 (1,160) | $4,200 – $6,000 |
| 1,200 (1,265) | $4,500 – $6,500 |
| 1,500 (1,581) | $5,500 – $8,000 |
Roof Pitch
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge). There are two suggested ways to measure a roof pitch.
Are flat roofs more expensive?
While flat roofs can cost more than pitched roofs and often require more maintenance, lower-sloped roofs have a clear advantage to homeowners. Flat roofs have large overhangs that do not block light because of their low slope.
How much does it cost to roof a 2200 sq ft house?
