Purpose of rain guttering

The main purpose of a rain gutter is to protect a building's foundation by channeling water away from its base. They also help to reduce erosion, prevent leaks in basements and crawlspaces, protect painted surfaces by reducing exposure to water, and provide a means to collect rainwater for later use. Ineffective covering can lead to expensive work to the underlying timbers and any decorative finishes, which will deteriorate rapidly in damp conditions.

There are gutters and downpipes suitable for many domestic and commercial installations. Essentially these are a traditional half-round profile or the modern square section, using round and square downpipes.

At L & L we first Check if fallen leaves and twigs have blocked the gutters and outlets, which could cause water to overflow, or pond on flat roofs.
When we are replacing an old gutter system, we plan to run a new downpipe to the original drain connections. for new building extensions or conservatories, we try to position new gutter outlets so that the downpipes run to an existing gully or drain. Alternatively, we install a new gully to the main drainage system or a soakaway may be built and the new connections can run to this.
All measurement and material calculation can be done at ground level. To calculate the quantity of gutter required we simply measure around the relevant elevations of the building. Corners, internal or external, are catered for by using the appropriate 90° or 135° gutter angles. All gutter angles must be fixed to the fascia. Corner angles should be fixed using support brackets not more than 150mm from each end of the fittings.
