How To Price A Roofing Job

Now that you know approximately how much the job will cost you, you have to decide what to charge your customer. According to Roofing Contractor, more than nine out of 10 roofing professionals wont achieve their goal revenue because they simply do the math wrong. If you want to make a 10 percent margin on a $1,000 job, you charge $1,111, not $1,100. How do you get to that number?

The total cost to you for this job is $1,000. If you want a 10 percent margin, those costs represent 90 percent of the final selling price, while the margin is the other 10. So, the final selling price is equal to the costs to you divided by the percentage: 1,000 / 0.90 = 1,111. Therefore, you charge the customer $1,111.

Lets say you wanted to calculate a 5 percent margin on this same job instead. If so, your costs would be 95 percent of the total selling cost, while the margin is the other five. Again, you write out the percentage as a decimal place and use the same formula. 1,000 / 0.95 = 1,052. So, to achieve a 5 percent margin, youd charge the customer $1,052.

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 roofs square footage.

Roofing in Raleigh 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, roof replacement 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 roof replacement price.

Steep roofs and multi-story buildings also add to the overall difficulty of roof replacement, adding to the final cost.

Measuring The Roof Pitch

Removing Old Roofing Vs Roofing

In most states, you are allowed to have up to two layers of asphalt shingles installed on your roof at a time. Roofing-over, or putting one layer of shingles over another, can save you significant amounts of money on your new roof because you avoid the labor involved in removing the old shingles. Roofing-over costs around $2 to $3 per square foot, as opposed to the average full replacement cost of $4.50. So, roofing-over a 2,000 square foot roof may only cost $4,000 to $6,000 instead of the $9,000 average.

Roofing-over presents some issues, however. Putting one layer of shingles on top of another does not address any potential underlying issues with your roof deck or . It also doubles the thickness of your roof and means that the new shingles may not lay as flat. In turn, this can mean that the new shingles will lift off more easily, and if the underlying shingles have any kind of moisture problem, this can cause the new shingles to deteriorate more rapidly. This means that the next roof project will require a full replacement and much sooner than if you had done it all at once the first time.
