Even skilled roofers can sometimes make mistakes in estimating the quantity of roofing fabric that will be wished for your roofing set up. There are unscrupulous contractors who will overestimate roofing cloth. Being capable of degree your very own roof from the ground can prevent hundreds or hundreds of bucks. By using this roof size guide you can arrive at an estimate to determine how a lot roofing material you'll need and compare it in your roofing quote.
Roofing materials are measured in squares. This simplifies matters by keeping the numbers smaller. One square equals an area of a hundred square feet (10 ft x 10 feet). So rather than saying your home requires 2500 rectangular feet of fabric, you would simply say 25 squares of fabric are wished.

Taking a floor dimension
The handiest tools you may need is a measuring tape. A a hundred foot tape will make the task easier, as will having a helper to maintain one give up of the tape while you report the space.
Start at one corner of your house and decide how tons overhang your roof has. Your measurements have to be taken as carefully as feasible at once beneath the out of doors of the overhanging roof. Work your manner around the house recording the measurements from every nook to the following. You will find that a simple comic strip of the residence outline could be useful.
Measurement of area is found through multiplying duration by using width. Most homes are not built of 1 easy rectangular or one rectangle. They are but, nearly continually made from a mixture of rectangles. Take a examine your cartoon and reduce the outside perimeter to easy rectangles, multiply the duration by means of width of every after which add the sums collectively. This will come up with the total quantity of rectangular toes of location underneath your roof. Divide this via one hundred and you'll have the wide variety of squares for your location.
Example: Your house can be 50 toes long and 30 toes huge. This could be duration (50 toes) x width (30 feet) = 1500 rectangular toes. Let us assume you've got a storage or every other room that stands proud 20 toes from your own home and is 25 ft wide. Again you would multiply period (20 toes x width (25 feet) = 500 rectangular toes. Adding the sums 1500 + 500 = 2000 rectangular feet. We divide that with the aid of a hundred to get 20 squares.
Determining Roof Pitch
Without an tool to measure roof pitch, you will need to estimate. To make things easier we can divide roof slopes into 3 categories and assign every a multiplier:
This might be a roof with a pitch of three:12 to 5:12, because of this the roof rises three to five feet for every 12 toes of base horizontal period. This type of roof is usually taken into consideration stroll capable making it less complicated to install. The multiplier might be 1.15 to 1.25. (More on what we do with this quantity later).
Medium Slope
This could be a roof with a pitch of more than 5:12 as much as 9:12, which means the roof rises as much as nine toes for every 12 toes of base horizontal duration. This kind of roof would require unique equipment and installation methods, making it greater high priced because it is not stroll in a position. The multiplier might be 1.25 to 1.4
Steep Slope
Roofs on this category have slope that is extra than nine toes of upward thrust for every 12 feet of horizontal run. Multiplier variance can variety from 1.4 for a easy gable roof to at least one.7 and more for a excessive pitch roof with many dormers and valleys. For these purposes, you may use a 1.5 multiplier for a steep slope with a large amount of dormers and valleys and get in the ballpark for an estimate. This kind of roof is the most hard and a few roofers are not equipped to install them.
