The roof pitch of a structure is the particular angle of the slope of the roof. The slope is represented by the proportion of inches in which a roof ascends perpendicularly for each of the 12 inches that it travels horizontally. More frequently, larger structures such as buildings may use a 4:12 slope, although they may vary depending on the necessity and requirements of the structure.
Roofs with higher slopes do have a lot of advantages for buildings, especially in elevated areas where precipitation may be at its highest peak. This helps in ensuring that snowfall or any amount of rain does not amass on the roof and increase the dangers of leaking. It also adds more space into a building where added area is needed for storage purposes. Aside from this, higher slopes are used for their aesthetic value, adding to the architectural beauty of a structure.
It goes without saying that having a higher roof pitch can be a lot costlier than the standard low ones. If you are interested in increasing your roof pitch, here are few considerations to keep in mind:
- Raising your roof pitch means that you will be building a brand new roof. Removing the old one is entirely up to you. The advantage of keeping the old roof is that it can offer added protection to your roof. On the other hand, the weight may be too heavy to be completely supported by your walls. Take the time to seriously consider your options before beginning your project.
- Determine the exact height in which you would like to raise your roof pitch. Place braces on any side of the peak of your roof that will span up to the length of space you would wish to raise the roof. To maintain the braces perpendicularly, make use of a plumb-bob. Your braces will make it much easier to determine the right angle where you will cut up the rafter’s ends. Make use of the side of one of your braces to make a mark on a section of lumber. Proceed to cut at the angle and keep this as your template for the proceeding cuts you will need to make.
- Make certain that you make use of an adequate V bracing to be able to hold up your new roof. Your rafters must be set on centers of about 16 or 24 inches, cut from lumber of about 2x6. The lumber’s crown side must always be on top or out of the load’s direction.
Raising your roof pitch may just be the best thing to do if you are looking to add more insulation into your home as well. Doing this on your own can be quite challenging though, even if you may have some sort of experience. When in doubt, talk to the experts for advice.
Also, it would always be a good idea to get your supplies from places where other professional roofers get theirs. It is more practical, economically, and you will be able to ask a few questions that could help you with your roofing project.
Do not rush when you are doing this. Take your time, as jobs done haphazardly can create very serious problems in the future.
