DIY Roof Replacement Cost Estimation Factors


Majority of roofing contractors agree the size of your roof raises labor and material costs the most. However, your DIY roof replacement cost will be less than this item.

The average roof size is about 3,000-5,000 feet. Furthermore, most roofing contractors divide the workspace by 100 square feet. Therefore, a 3,000-square foot roof is equivalent to 30 squares of work.

Then, you can start calculating the total labor costs by multiplying $4-$6 by 100 square feet (equal to one roof square).

The logic behind this is $4-$6 is the average roof labor cost per square foot. Therefore, you can get about $400-$600 roof labor cost per square.

If you have a 3,000-square feet home, then you have 30 squares.

Your total roof labor costs ranges around $12,000-$18,000 on average.

The formula for this is labor charge per square multiplied by number of squares to work on. In this example, this is $400-$600 multiplied by 30.

True enough, you save so much from per-square labor going DIY.


DIY roof replacement cost disregards roof pitch cost factors. You’ll take more time doing it yourself, but you’re not paying someone by the hour or roof square.

The pitch of your roof requires extra materials. In addition, roofing contractors place a premium on complex roof designs.

For example, you have a butterfly or inward roof shape. Roofing contractors must approach the replacement carefully. Therefore, their use of extra equipment such as safety harnesses and even a construction crane in some cases will elevate roof replacement costs.

True enough, we cannot ascertain these additional roofing costs. However, they will definitely add a few hundred to the final labor costs you’ll receive.

However, you’ll have less to pay for as your DIY roof replacement cost will reflect in the future.

An asphalt shingle roof costs about $5-$7 per square foot. Therefore, you’ll spend about $15,000-$21,000 to roof a 3,000-square foot property.

Inevitably, this is the biggest expenditure on the final bill of your DIY roof replacement cost. If you add this amount to the total labor expense of a 3,000-square foot roof, you’ll get about $29,000-$39,000 on average.

Furthermore, premium roof materials will increase these final estimates by a mile. For example, a standing seam metal roof costs about $12-$15 per square foot. Therefore, your total roofing material expense is at $36,000-$45,000 in total.

Therefore, your savings are extremely huge when you go DIY.

Go DIY or Trust a Roofing Contractor With Roof Replacement?

True enough, you’re saving more than tens of thousands without professional help. However, you’ll have to consider some cons about DIY roofing.

Doing it yourself means committing time. This means your roof replacement may take months or even more than a year to accomplish. In addition, you won’t find time to rest during weekends working on your roof.

Furthermore, athleticism is important in roofing. You’ll need to climb roofs. Then, you’ll need to balance yourself while carrying roofing materials. In fact, you’ll be struggling against the hot sunlight for hours while working.
