Establishing the Roofing Estimate
The roofing estimate is typically the price and a description of the product that the contractor intends to use. The calculation gives a rough figure of the amount that the project will cost. There are several steps that one needs to do to get a very accurate roofing estimate. Find a roofing contractor if you want to roof your house. These steps are discussed in this article.
Steps
Estimating the squares needed for the roof
One must know how many squares are needed for the roofing. To do this, one must determine the slope or pitch of 
the ceiling. These are measured regarding rising and run. The series measured from the edge which is outside the perimeter stud wall up to the middle of the building.
The rise is the measured from the top of a stud wall to the peak of the roof. The pitch of the roof is estimated by how much it rises for every foot it runs.
Counting the shingles
It is achieved by measuring the length and width of each portion of the roof. After that multiply the length by width for each plane and add the planes together to get the total square footage. After getting the total square footage, determine the total number of squares by dividing the total footage by a hundred. One has to account or waste to determine the most accurate estimate. It is done by adding ten percent to the shingle view.
Estimate felt underlayment
It is done by again finding the square footage of the roof and the number of squares using the same formula. Afterward, one has to determine the number of rolls that the underlayment requires. It depends on the roof slope and the steeper it is; the more turns are needed for the underlayment.
Estimate other materials
Roofing requires a variety of materials and one has to determine the amount that one will need for the success of the project. Beneath the underlayment, a drip edge which is a metal strip is required to protect the edge of the rooftop from rotting. To estimate this, one will have to measure the rates and then eaves of the roof to determine the number of strips that are required.
Roofing nails are necessary for the construction, and it is vital to establish how many one needs. The average number is four nails per shingle which is about 320 nails per square. One can either order exclusive hip and ridge cap shingles or make by cutting a 3-tab shingle into three pieces depending on the budget of the total project. The disadvantage of making the shingles is that the pieces might not be in a standard size and shape as compared to the ones that can be ordered.
