Following the steps outlined below to calculate roof replacement costs will help you arrive at the cost quickly and easily. The most important step to find the cost is the area of the roof. Typically homes with moderate slopes are double the floor area. So, if you have 1,200 square foot home your roof will measure around 2400 square foot. With the roofing area know it is easy to calculate the amount of materials like shingles needed.
Next, it is critical to know the roof’s slope to calculate roof replacement costs. Flat, low slope and moderate slopes are easy to work on. Steep ones are difficult and so the installation costs are proportionately higher. The lowest roofing installation prices are for flat ones, followed by low-slope and moderate sloped ones. Here the roofing contractor is able to comfortably stand on it while working on it. The steeper the roof the more difficult it is for the contractor and he will need safety equipment and extra tools and products to help him in the installation.
Complex roofs are the most expensive ones to replace. The projections, depressions, valleys and ridges make the job of installation difficult and time-consuming. The number of points which need flashing increases. The amount of shingles needed to completely seal of these vulnerable points on the roof add to the materials costs and also cost of labor. So, the more complex it is the more difficult it is to replace. The degree of difficulty adds to the cost of the roofing. Calculating roof replacement costs depends to a large extent on its complexity.
Whether your old shingles need removal depends on the type of material you are going for. Some shingle materials are heavy and they will add considerable stress to the supporting structure so, if either your previous one or present roof is of the heavier kind it probably needs to be removed before new shingles are installed. If it is simple asphalt roof then you can install a new layer of asphalt over the old one. If you are planning to change from asphalt to wood then the previous layer has to go. This adds to the roof replacement cost. So, to calculate the cost of roof replacement you need to know if the old shingles layers needs to go.
Material choice makes a big impact when its time to calculate roof replacement costs. Asphalt roofing shingles are the cheapest while wood, slate and metal are the costlier options. The installation of metal roofs and slate is also complex and needs special skills. Some roofs can be installed by only the companies trained by the manufacturers. So, that significantly impacts the pricing of the new roof.
Your location is another factor that impacts the cost of roof replacement. There are many roofing cost calculators that have all the data regarding local prices of roofing shingles per-loaded. Just entering the zip code of your area allow you to easily calculate roof replacement costs.
Keeping in mind the above factors helps cost of roofing with ease.
