Roof Gutter: Choosing the Right Sizes

Installing a new guttering system can be a relatively simple do-it-yourself project, but ensuring that you have the correct guttering to install can be more difficult. Climbing a set of ladders to measure your roof, determine the pitch (angle of the slope), and compute the quantity of rainfall the guttering will have to handle might be a terrifying concept. Fortunately, there are a few various strategies for accomplishing this; simple, safe, and accurate. 

Under or oversizing the guttering required for your property is something you should avoid at all costs. If you install gutters that are too small for your roof, they will clog up faster, necessitating more frequent cleaning, overflowing in heavy downpours, or even failing to catch rainwater run-off entirely if they are too narrow.

However, if you adopt a “bigger is better” and “better safe than sorry” mindset, you may be able to avoid these performance issues, but there are some caveats. For starters, oversized guttering can be very unsightly and detract from the appearance of your home. It will also be more expensive, costing you more money than you needed to spend. So, what are you going to do? How do you go about choosing the best guttering for your home? So, let’s take a look at your choices.

Types of Roof 

Before we get started on the measurement techniques, we need to quickly tackle the problem of what type of roof you have. There are many various designs of roofing out there and some of them can be very tough to properly measure up. 

The most prevalent forms nevertheless are either Gable or Hip roofs, and, as such, those will be the ones we focus on in this post. If you have a more complex roof style or form, you may still utilize the procedures we will be discussing, but you’ll need to draw up a design of your roof and make sure to measure all the different roof surfaces separately. It can be done, but we’d strongly recommend calling in an expert to aid you if you are in any way unclear how to collect correct measurements

Knowing the effective area of your roof and the gutter flow capacity should enable you to begin along with any guttering manufacturer or stockist and use their comparison charts to figure out what size guttering you need. 

Using a running outlet to install your downpipe in the centre of your gutter run actually increases the gutter flow capacity and the effective roof area that the system can handle. The downside is that it may result in a downpipe that is more visible down your wall rather than off to one side, which is not ideal for gable roofed homes. 

There is nothing wrong with having your outlet at the end of the run, as long as you choose the appropriate system based on the gutter flow and roof area figures in the applicable table. However, if you require a larger capacity but do not wish to purchase a larger sized gutter, it is worth considering the centre run outlet.
