A beginner’s guide to rainwater goods for homebuilding and renovating

Galvanized steel guttering is deeper and stronger than plastic, creating a longer lasting rainwater management system that will resist thermal expansion and contraction providing greater joint integrity – ideal in the UK where the weather variations really test gutter joints. And offering greater capacity and better flow/discharge rates (also see UK weather!). Some systems come with manufacturer’s guarantees of 15 years although life expectancy should be more like 25 years. 

Eco-friendly & sustainable?

Steel is 100% recyclable saving landfill space and conserving natural resources (unlike plastic, created from limited fossil fuels and becoming a nuisance at the end of its useful life).

Installation

Steel is lightweight and easy to handle. The 3m lengths make for swift installation. It can be installed by a professional or an experienced DIYer.

Style & Finish

A half round profile is available in either Galvanised Steel or the usual black, grey, white or brown colour-coated galvanised steel off the shelf for next day delivery, but can also be ‘bespoke’ ordered in almost unlimited colours with an additional surcharge and a longer wait. 

Who does it suit?

Has been used to great effect on both contemporary and traditional style buildings. 

Plain galvanised material is not advised for projects in coastal regions where salt water can have a corrosive reaction. In these instances, the colour-coated, zinc or copper systems are recommended instead.

Guide Price

Based on standard 115mm, half round, plain uncoated Galvanised Steel gutter our guide price is £18.48 for a 3m length including our current £15% Online Discount BUT from July 2018 it will be just £16.31 per 3m length with the new, incredible 25% OFF SUMMER STEEL DEAL.

Modern aluminium guttering is lightweight, easy to handle and 3m long lengths make it an ideal choice for quick installation. 

Installation

Style & Finish

The SnapIT extruded ranges come in half-round, vintage moulded ogee, deep-flow and contemporary joggle box profiles. There is a choice of matt or ‘heritage textured’ 26 colours.

Guide Price

A SnapIt 115mm, half round, powder coated extruded aluminium gutter our guide price is £47.24 per 3m length including our current £15% Online Discount (06/18)

Who does it suit?

Leading choice for the construction industry. With such a wide choice of profiles and matt or textured finish – can suit all types of building projects.

Cast aluminium guttering should last in excess of 25 years in a normal domestic application system.

Installation

It can be installed by a professional or an experienced DIYer. 

Style & Finish

Half round is the most popular profile but it comes in Victorian ogee and moulded too. Available pre-coated in 26 standard factory-applied, powder coated options for immediate installation. 80% of the aluminium rainwater systems already in use in the UK have been manufactured from recycled aluminium and all aluminium is infinitely recyclable at the end of its life.

Guide Price

A 125mm, half round, textured black powder coated cast aluminium gutter is £56.31 per 6ft/1.83m length including our current £20% Online Discount (06/18).

Who does it suit?

Looks best on high quality or traditional heritage style projects.

Cast Iron guttering, the traditional material for rainwater management that lasts 100years+ with proper maintenance, comes in Half-Round, Victorian Ogee or Moulded profiles; primed, for painting on site,

Guide Price

Based on the 4” half round profile, primed for painting onsite:  £25.12 per 6ft length -  or pre-painted black, ready to install: £32.59 per 6ft length including our current £45% Online Discount (06/18).

Read our ‘Primed or Painted: Which to Choose?’ blog [bit.ly/CIPrimedOrPainted] to find out why Rainclaer would highly recommend spending that bit extra for the factory pre-painted cast iron because of how effectively the long-term benefits outweigh the initial incremental investment.

Installation

As this is a heavier system it really needs to be installed by two people and from scaffolding. A very competent DIYer with assistance would be able to install this system. 

Eco-friendly & sustainable?

It may look like an expensive initial investment, but it offers an unrivalled life of 100years+ with proper maintenance, actually making it great value for money. This very long life makes it a great choice for the environment too, as it uses less natural resources over the life time of its installation. It is 100% recyclable at the end of its useful life.

Who does it suit?

Cast iron looks best on traditional heritage style projects and an absolute must on listed properties.

Copper protects itself by forming a patina that ensures an exceptionally long product life span of 100+ years.

Installation

No special skills are required to install the copper guttering. The clever design makes installation simple. No soldering, riveting or messy silicone.

Style & Finish

Left to age naturally copper guttering will start to mellow within weeks, changing through various shades of rustic brown and bronze until eventually forming a green / blue patina unique to copper. The time taken for the patina process to start depends on the location of your property, local weather conditions, distance from the sea and other forms of acidic pollution. It may be a more expensive choice initially, but its beauty, durability and recycle-ability – reducing environmental impact – makes it the more cost-effective choice as the long-term advantages far outweigh the initial outlay.

Eco-friendly & sustainable?

Copper is sustainable, it is 100% recyclable with most mined copper still in use today, reducing its environmental impact. Copper guttering is particularly suited for use in conjunction with a copper roof as a means of rainwater harvesting. It acts as an algaecide and fungicide, keeping growths such as moss and lichen to a minimum, therefore keeping gutters clear. Also, it mildly disinfects the water, which is great for putting on plants as it has a balanced pH and is free from chemicals such as chlorine. You get more suds when washing the car and it makes car and window washing smear-free (the streaks and dots are limescale).

Guide Price

Based on standard 115mm, half round profile, our current guide price is £56.38 per 3m length including our current £40% Online Discount (06/18)

Who does it suit?

Copper has been used on both contemporary and traditional style buildings. Its distinct appearance adds a very specific architectural and a real ‘eco’ statement to most types of building.

Maintenance

It is a wonderfully low-maintenance option for guttering systems as it will not require painting or cleaning (if you are happy to allow it to patina with age) other than the removal of debris that may fall into the guttering

  • Always place ladders against structures and not the rainwater system
  • Check annually to ensure fixing points on brackets remain secure
  • Do not clean external surfaces abrasively to retain initial shine. The natural patina (a slow oxidisation of the outer molecular surface) creates its own protection against UV rays, heat, wind & water and so should not be avoided.

Over time, Zinc forms a thin layer called a ‘patina’. This patina covers the material and protects it from weather elements, such as sun, wind and water but the change is practically invisible. It is immune to the harmful effects of UV rays. a lifespan of nearly 100 years

Installation

Lightweight and easy to install. No special skills required. The clever design makes it simple. Rainclear have produced some brief videos explaining things like gluing in the stopends. You can find it and others on Rainclearsys - You Tube: http://bit.ly/RCUTube

Style & Finish

Choosing Zinc as a rainwater solution is stylish statement for those after a different, unique finish that will maintain a striking appearance. The ‘quartz’ zinc Rainclear stock has the colour and texture of ‘pre-weathered’ zinc.

Eco-friendly & sustainable?

There is no shortage of zinc as a resource and in addition it can be 100% recycled at end of life. Many customers today want to lower their carbon footprint and reduce their impact on the planet. Zinc offers this.

Guide Price

Based on standard 115mm, half round profile, our current guide price is £61.46 per 3m length

including our current £40% Online Discount (06/18)

Who does it suit?

Quartz Zinc has been used on both contemporary and traditional style buildings. Its distinct appearance; a dark and textured gun-metal grey, adds a specific architectural and eco statement to most types of building. It is ideal if you live in an exposed location or by the coast. Its hard-wearing properties mean Zinc will last up to 50 years even in this most testing environment.

Maintenance

Requiring no decoration or cleaning, just the removal of debris that may fall into the guttering, makes it suitable for commercial, civic and residential buildings.
