Do I Need Larger Gutters for My Central Coast Home?

What are the advantages of installing wider gutters and downpipes?

  • Improved water flow: Wider gutters can carry away more water efficiently.
  • Reduced maintenance: Larger gutters with wider openings are less likely to clog from debris buildup, reducing the frequency of gutter cleaning needed. This saves time and effort on maintenance.
  • Longevity:With less debris accumulation, larger gutters experience lower risks of corrosion, extending their lifespan and reducing long-term maintenance costs.
  • Better protection: The increased clearance from the roof edge provided by larger gutters helps prevent water from damaging soffits, fascia boards, and other exterior elements of your home

How To Decide If You Need Larger Gutters

Choosing the right gutter size for a home requires careful consideration of multiple elements. Rainfall patterns in the area play a crucial role, as regions with heavier rainfall might benefit from larger gutters to manage the increased water volume effectively.

Other factors include the size and pitch of the roof. Steeper roofs cause water to flow more quickly, necessitating larger gutters to handle the rapid runoff effectively.
There are a lot of factors that play into what gutters and downpipes you have on your home

The Local Rainfall

The Central Coast has recently had unprecedented rainfall and severe storms.
Homes need to be prepared to face heavy rainfall events.
Larger gutters will handle the increased water flow, reducing the chances of gutters overflowing. This helps in preventing water damage to the home’s foundation, siding, and garden areas.
Larger gutters will be able to manage intense weather conditions and help avoide water damage to your property. One thing to note is that your down pipes will also need to be looked at. Increasing the size of the downpipes or installing additional downpipes so the extra water volumes can quickly be dispersed in to the storm water system

Roof Size, Pitch And Material

The size and pitch of a roof influence how much water it sheds and how quickly the water flows into the gutters.

Long rooflines or homes with multiple roof levels should consider larger gutters to handle the extra water efficiently.
Larger roofs and those with steeper angles will need larger gutters to handle the increased water runoff.
What your roof is made of is also a factor. Water moves faster on a metal roof than a tiled roof, so when installing a new metal roof it is always an idea to increase the size of your gutters

Leaf and Debris Management

Houses surrounded by trees experience heavy leaf fall, tree litter.
If your gutters do get a lot of leaf litter upgrading to larger gutters and installing gutter guards will help to keep your gutters free flowing.

Gutter guards have improved greatly and we often install gutter guards whenever we install new guttering on a home.

Preventing blocked gutters ensures that water flows efficiently and reducing the risk of maintenance problems.

Gutters that have debris sitting in them will have a shortened lifespan as it leads to premature corrosion with the wet sludge sitting there all year round.
This added weight in the gutters will cause them to come away from the fascias and it looks unsightly when the gutters are not maintained

How is the guttering requirements that my house needs worked out?

The guttering required for your Central Coast home can be different than a home in the Queensland outback or a home in Hobart.
The size of your roof, local rainfall patterns and local rainfall data is has to be taken into consideration

The Size of The Roof Catchment Calculations

AWS are roof plumbers and when we are installing new roofs and gutters, we must do the below calculations.

The formula for calculating the roof catchment capacity is: Annual Rainfall (in millimeters) x Roof Surface Area (in square meters) = Roof Catchment Capacity (in liters) To break it down:

Annual Rainfall: This is the average annual rainfall for your location, measured in millimeters (mm).

  1. Roof Surface Area: This is the total horizontal area of your roof, measured in square meters (m²). For sloped roofs, use the horizontal projection area, not the actual sloped surface area.
  2. Roof Catchment Capacity: This is the theoretical maximum amount of rainwater that can be collected from your roof annually.

    The total roof size, along with the local rainfall intensity data, will then be used to select the appropriate gutter size and number of downpipes – Read more here

    What are the implications of guttering that is too small for a house?

    Choosing gutters that are too small can lead to:

    • Overflowing: Water spills over the sides during heavy rain, which can damage the siding and foundation.
    • Frequent blockages: Smaller gutters clog easier, increasing maintenance needs.
    • Water damage: Inefficient drainage can cause water to pool around the home’s base, leading to potential structural issues.
