The name was adopted in 1929 after Alliott Verdon Roe (see Avro) and John Lord took a controlling interest in the boat-builders S. E. Saunders. Prior to this (excepting for the Sopwith/Saunders Bat Boat) the products were Saunders, the A4 Medina for example dating from 1926. Sam Saunders the founder developed the Consuta material used in marine and aviation craft.
Saunders Roe concentrated on producing flying-boats, but none were produced in very large quantities – the longest run being 31 Londons. They also produced hulls for the Blackburn Bluebird. During the Second World War Saro manufactured Supermarine Walrus and Supermarine Sea Otters. Their works at Beaumaris, Anglesey, modified and serviced Catalinas for the Royal Air Force.
In January 1931 Flight magazine revealed that Whitehall Securities Corporation Limited acquired a substantial holding in Saunders Roe. Whitehall Securities was already a large shareholder in Spartan Aircraft Ltd, of Southampton, and arising out of this investment Spartan was effectively merged into Saunders Roe.
In 1938 Saunders-Roe undertook a re-organisation of the commercial and administrative sides of its business. First, the marine section, consisting of the shipyard and boat building business, was transferred to a new company, Saunders Shipyard Ltd., all of the shares of which were owned by Saunders-Roe Ltd. Mr. C. Inglis was appointed shipyard manager. Secondly, the plywood section of the business carried on at the factory on the River Medina was transferred to a new company, Saro Laminated Wood Products Ltd., in consideration for a majority of the shares therein. Laminated Wood Products Ltd., which had marketed most of the plywood output, also merged its interests into the new company. Major Darwin, managing director, left the company. On the aircraft side of the business Mr. Broadsmith continued as director and general manager. All other senior posts in the executive staff remain unchanged.
In 1947 they flew the SR.A/1 fighter prototype, one of the world's first jet-powered flying boats, and in 1952 they flew the prototype Princess airliner, but the age of the flying-boat was over and the two further Princess examples to be completed were never flown. No further new seaplanes were produced here. Modification work on Short-built flying boats continued at Cowes until 1955.
The last fixed-wing aircraft they built was experimental SR53 mixed-power interceptor.

In the same year Saro's helicopter and hovercraft interests were taken over by Westland Aircraft which continued the Skeeter family with the Scout and Wasp. In 1964 all the hovercraft businesses under Westland were merged with Vickers-Armstrongs to form the British Hovercraft Corporation. This, in turn, was taken over by Westland and was renamed Westland Aerospace in 1985, and hovercraft production was reduced to nearly nothing until the advent of the AP1-88. The company produced sub contract work for Britten-Norman, produced composites and component parts for the aircraft industry, especially engine nacelles for many aircraft including the De Havilland Canada "Dash 8", the Lockheed Hercules, the British Aerospace Jetstream and parts for the McDonnell-Douglas MD-11. By the mid-1990s, over 60% of the world's production of turboprop nacelles took place in the East Cowes works.
In the late 1960s/early 1970s the Saunders-Roe Folly Works, by then owned by Hawker Siddeley was merged with the Gloster works to form Gloster-Saro utilising both companies' expertise in aluminium forming to produce fire appliances and tankers in the Gloster factory at Hucclecote, mostly based on Reynolds-Boughton chassis. In 1984 Gloster Saro acquired the fire tender business of the Chubb group with the company merging in 1987 with Simon Engineering to form Simon Gloster Saro
In 1994 Westland was taken over by GKN, and when GKN sold off its shares of Westland to form Agusta-Westland, it retained the East Cowes works, where it continues aircraft component design and production.
Laird (Anglesey) Ltd was formed in 1968 and incorporated the Beaumaris and Llangefni factories of Saunders-Roe and the engineering business of Birkenhead shipbuilders Cammell Laird. Laird developed the Centaur, which was half Land Rover and half light tank. The company is now known as FAUN Municipal Vehicles Ltd.having been taken over yet again. Today, FAUN manufactures portable aluminium roadways and runways at Llangefni under its TRACKWAY brand.
In 2015, the East Cowes Columbine Hangar (famously now with the huge Union Jack painted on its doors) was leased from Homes & Communities Agency to Shemara Refit (now Wight Shipyard Co. Ltd), who have constructed the catamaran ferry Red Jet 6 inside the hangar for use by Red Funnel Ferries, with the next Red Jet in the series, Red Jet 7, also under construction there. The GKN North site had sold in 2002 for £8m to a government quango, SEEDA, South East Enterprise Development Agency for the regeneration of East Cowes. That stalled with the financial crash in 2008 and is set never to achieve the sites full potential as a deep water Prime Tier 1 Marine Industrial Site.

With the Royal Aircraft Establishment
The Rocket Development Division was formed in 1956 and the Rocket Test site at Highdown started functioning exactly one year later. The division was headquartered at Yeovil. It was this Division, in conjunction with the Royal Aircraft Establishment, that was responsible for the design, manufacture and static testing of the Black Knight Rocket, the first of which was successfully fired at Woomera, South Australia, on 7 September 1958.

The Electronics Division was formed in 1948. Its progress was rapid and the Division also designed and manufactured such diverse specialist equipment as Analogue Computers, Control Simulators and a variety of Electronic Equipment and Electronic Test sets associated with Guided Weapons. When using strain gauges of the normal wire type in the dynamic testing of helicopter components, notably rotor blades, Saunders-Roe found that such a high proportion of the gauges were failing that development was considerably retarded. The Electronics Division was therefore asked to devise an improved gauge and, in collaboration with Messrs. Technograph Printed Circuits Ltd., produced the foil strain gauge.
- R-103 – a 17-ton hydrofoil for Royal Canadian Navy, Known as "Bras d'Or". Built in 1956 by Saunders-Roe (Anglesey) Ltd. (This should not be confused with HMCS Bras d'Or, a 240 tonne hydrofoil patrol vessel, which was the result of the tests performed by the R-103)
Early in aviation, it was difficult – if not impossible – to supply uninterrupted power in aircraft. Saunders-Roe solved this problem by putting an ionising gas (tritium; 3H) in small tubes. Tritium was discovered in 1934 by Lord Rutherford. The tubes ("Betalights") are made of borosilicate glass. The inside of the tubes is coated with a fluorescent powder, which glows as a result of the ionizing radiation of the tritium gas. Such a tube emits light for 15 years. Betalights were used to illuminate the flight instruments, exit signs and corridors of the aircraft produced by Saunders-Roe. When Saunders-Roe was acquired by Westland Helicopters production continued via Saunders-Roe Developments Ltd of North Hyde Road, Hayes, Middlesex (the former Fairey Aviation Head office). Betalight production was made independent under the name SRBT (Saunders-Roe Betalight Technology). A factory was established in Pembroke, Ontario, Canada, where tritium supplies are readily available. Today betalights are used in self luminous escape-route signs, under the product name Betalux.
Mark 3 airborne lifeboat
In early 1953, Saunders-Roe at Anglesey completed the Mark 3 airborne lifeboat to be fitted underneath the Avro Shackleton maritime reconnaissance aircraft. This model was made entirely of aluminium, previous marks being made of timber. Parachuted at a rate of 20 feet per second into the rescue zone, the craft was powered by a Vincent motorcycles HRD T5 15 hp engine; sails and a fishing kit were also provided. The Mark 3 measured 31 feet (9 m) from bow to stern and 7 feet (2 m) across the beam and held enough to supply 10 people with food and water for 14 days.
During World War II, Saunders-Roe opened a factory at Fryars in Llanfaes, Anglesey, converting and maintaining Catalina flying boats. In the late 1940s and 1950s the Beaumaris factory began making bus bodies under the names Saunders, SEAS (Saunders Engineering & Shipbuilding) and SARO. When AEC took over Crossley Motors, many of the design staff left and joined SARO. In pre-Atlantean days when Leyland began looking at low floor vehicles, the "Low Loader" (STF 90) bodied by SARO was similar in certain respects to the Crossley chassisless bus designs. Bodies were manufactured at Beaumaris for installing on "Leyland Royal Tiger" and "Leyland Tiger Cub" chassis; SARO bodied 250 RTs for London Transport between 1948 and 1950 (RT 1152–1401), which were almost indistinguishable from the standard Weymann/Park Royal products; and some double-deck buses for Liverpool Corporation. 620 prefabricated Rivalloy (the brand name comes from rivetted (aluminium) alloy) single deck buses components for local assembly were sold to Autobuses Modernos SA, Cuba which later became Omnibus Metropolitanos, S.A. Another large customer was Auckland Regional Transport in New Zealand who took the Rivalloy body on 90 Daimler Freeline chassis.
In the UK large numbers of SARO bodies were specified by the British Electric Traction group on Leyland Tiger Cub chassis, operators including Trent, East Midland, Ribble and the Northern General Group. An integral version of the body design powered by a Gardner 5HLW engine was bought by Maidstone & District.
The factory later passed to Cammell Laird who mainly used it for producing refuse-collection vehicles, but when Metro Cammell Weymann had a production backlog, they completed a batch of MCW-style double deck forward-entrance highbridge bodies on Leyland Titan PD3 for Brighton Corporation, these were numbered 31-5, registered LUF131-5F and delivered in June and July 1968, they were unusual as front engined half-cab buses built to be driver operated.
