Estimating Materials For Roofing Projects

Here are some guidelines to making an estimate for materials for a roofing project. In making an estimate it is useful to separate your roof into parts. Tackle the estimate for the different parts and then combine them all to get a general figure of how much your materials will cost in the end. Try this. Make an estimate for:

  1. The shingle
  2. The tar paper
  3. Any other materials needed.

When estimating for materials needed for the shingles, here are some steps that can guide you through that estimate process.

  1. Measure The Roof

Determine the entire square footage of the roof by taking measurements with of both the width and the length of each part of the roof, multiplying the width and the length of each plane, and then find the sum of all the planes together to find the total square footage.

  1. Find The Total Number Of Squares

Now, using the total square footage found above, all you need to do is divide the total footage you got by 100 to determine the total number of %u201C squares%u201D on the roof.

  1. Number Of Shingles You Need

Depending on the type of shingles you are planning to use, you can find the number of shingle boxes you need to buy. For instance, if you are using 3-tab shingles, which is the most common, then you will need approximately three boxes of shingles.

  1. Waste

Making an estimate is done mainly to eliminate wastage of materials by purchasing excess. However, it is important to budget for any waste that may occur. Then add about five to ten percent to the estimate that you got for your shingles. If you may need alterations made to the shingles due to the shape of your roof, factor that in as well, with about a fifteen percent increase to the total estimate that you got for your shingles. As they say, failing to plan is planning to fail.

Tar Paper Is The Next Estimate You Will Need Tar paper is a waterproof construction material used for roofing used as a weather barrier for your roof. It keeps off rain water from damaging your roof excessively. When estimating for the tar paper the following guidelines will come in handy.

  1. Measure The Roof

Again, you need to find the square footage of the roof as we did before when measuring the roof in order to determine the number of shingles we need. The process is similar to that. Remember to factor in any valleys and hips that your roof may have for a more accurate measurement.

  1. Find The Total Number Of Squares

Here again as we did when finding the total squares for the purpose of buying shingles, we will use the same method to determine the total number of squares on the roof. Divide the total square footage by 100. 3.Number Of Tar Paper Rolls One roll of tar paper covers about four squares. Sometimes you may need to use a double layer of tar paper on your roof. As I mentioned before, ensure that you are working with a licensed roofing contractor to help you figure out what exactly your roof needs. This will give you a more accurate estimate.

Finally, among the materials you will need for your roof are sort of miscellaneous materials that assist in the actual building of the roof. These are critical and therefore must be factored in to the equation to make for a realistic estimate for materials needed for a roofing project. It is important that if you are not conversant with roofing projects, to partner with someone who is or seek advice from a licensed roofing contractor for this step. This is because some of these materials are not something anyone can easily think of or see on the roof itself. These include materials such as:

  1. Metal strips for the drip edge which is placed underneath the tar paper. What it does is to protect the edge of the roof from rot.

2.Roofing nails. Make an inquiry at a hardware shop on what size of nails you will need for the roofing project and how many pounds of those nails you will need. This is critical to the project.

  1. Venting materials.
  2. Delivery charge for the materials. This can be determined once you have settled on all the materials you need and the best place to buy them. It is wise to compare bids from different hardware stores.
