§ Type 01 — Application
Residential
Protect your family and your investment with engineered roof saturation designed for modern homes.
§ Overview
Ridge configuration — RES
Protect your family and your investment with engineered roof saturation designed for modern homes.
Single-run ridge configuration for pitched domestic roofs, sized around one continuous supply and one manual isolation valve.
Use the Rainmaker System Designer to configure the modular platform to your architecture, water source and roofline — the calculator returns module count, layout and pricing in under two minutes.
§ Intended applications
Specified for these environments.
- Pitched tile, slate, concrete or sheet-metal family homes
- Guest cottages, flatlets and garden outbuildings
- Double-storey homes where ridge height increases static head
- Rooftop solar arrays requiring periodic rinse-down
- Retrofit onto existing rooflines without lifting roof sheets
Not specified for
- Thatch or organic roof coverings — specify the Thatch configuration
- Roof runs beyond a single supply zone — specify Estates or Commercial
§ Engineering specifications
Specified for residential conditions.

§ Engineering notes
Why this configuration is built the way it is.
- Roof height is entered in the System Designer so static head loss is compensated in the pump and pressure recommendation.
- Pipework is supplied in a standard colour and may be colour-matched to the roof after installation.
- Run duration is limited only by the available water supply; there is no reset procedure after use.
