One of the most important questions you will have when you are estimating your roofing cost is how many square feet of roofing do you require. If you don’t know how many square feet your house requires, you won’t be able to use any type of roofing calculator. Make sure you get an exact number by measuring each individual shingle and using the formula for the square footage. Using this formula you can get the exact square footage you will need.

If you have enough information to make an accurate estimate, then you are ready to start your project. Start with measuring the area where the home will be situated. Look up the building code regulations for the area to find out the square footage required. You can also contact your roofing contractor’s estimate and ask them for a copy of it. If they do not have a copy you can purchase it from the government website.

Next you will want to take the measurements of the area around the outside of the house. Most homes have some sort of perimeter fencing around the outside. This will need to be measured to be certain the new roof will fit. Find the distance between the top of the pole and the ceiling or the wall to determine how many new roofing shingles you will need.

The next step is to add the new square footage to your old square footage. Use the roofing materials calculator to determine how many new shingles you will need to cover the area. Remember to leave space for flashing around the perimeter of the new shingles. You can also get an idea of how many more tiles you will need by using the spreadsheet online.

When you are using a roofing materials calculator, remember to factor in the cost of cutting and adding nails, screws, and such. Also, consider the cost of your roof replacement. This will include all the labor costs associated with the actual repair. If the estimated total is much higher than the actual cost, you may be better off starting the job with a low expectation and then checking the final price once the work has begun.

Another important aspect of estimating how to estimate roofing cost is the roof pitch. The actual replacement cost will depend on how much materials you purchase, the difficulty of installation, and whether you choose a newer style or a more traditional look. With a professional roofer, you can also get estimates for the type of roof you want as well as the roof pitch. The calculator can provide you with the answers you need to make this determination.
