Robert de Roos died "sometime in 1227, and was buried in the Temple Church at London" "An effigy in that church sometimes associated with him dates from at least a generation later."
His date of death is not known, but his son and heir, William de Ros, did homage for his father's lands 23 December 1226, so whether he had died by this time, or as some speculate, as a Templar, had retired from secular life, is not known.
Titles and Lands
for "Robert de Ros, surnamed Furfan", of Helmsley and Hunsingore, Yorkshire, and Wark, Northumberland
Knight Templar "At some stage he was received into the ranks of the Templars and on his death he was buried in the Temple Church in London, where a few years earlier William Marshal, the one-time Regent had been buried. An effigy in that church sometimes associated with him dates from at least a generation later."
Furfan, Robert de Ros, as a minor at his father's death was the ward of the King in 1185, when his lands were in the custody of Ranulph de Glanville. In 1190 he had livery of the lands of his Trussebut inheritance.(of interest: Ranulph's WikiTree profile shows he died 1190)
Robert, son of Everard de Ros of Helmsley or Hamlake in the North Riding of Yorkshire. The family also held lands in Holderness, where was situated Ros, to which they gave, or from which they received, their name. Robert succeeded to his father's lands in 1191, paying a relief of 1000 makrs. In 1195 he was bailiff and castellan of Bonneville-sur-Touques in Lower Normandy near which the Norman lands of the family lay.
6 Jan 1200: King granted all honors and lands that belonged to Walter Espec (g-g-grandfather to Robert) in Northumberland, including Wark where Robert built a castle. "...it is recorded in the Chartulary of Rievaulx Abbey that he 'raised the Castles of Helmislay and of Wark'." 
Robert de Ros...in the 1st Richard I , paid 1,000 marks fine to the crown for livery of his lands.
10 Apr 1215: received the royal manors of Sowerby, Carleton, and Oulsby, all near Penrith in Cumberland and Westmoreland.
He joined with Peter de Brus and Richard de Percy, in attempting to subdue Yorkshire. All his lands in Yorkshire were granted, but he returned to his allegiance in November 1217, and his Cumberland estates were confirmed to him in 1218.
Henry III commanded his manors of Sowerby, Carleton, and Oulsby to be restored to him on 23 July 1218, and orders to different bailiffs of the king to allow him to hold his lands unmolested were issued on 22 Nov 1220.
Bonneville Castle - from timeline - 1196 [Richard I] handed over to Robert's keeping Hugh de Chaumont,... Robert imprisoned him in his castle of Bonneville.
Carlisle Castle - from timeline - 1216: After king's success in the north... a castle belonging to Robert was one of the only two that remained in the possession of the barons in the north.next timeline entry mentioned Carlisle Castle so presumably, that was the castle referred to as belonging to Robert.
Distribution of Estate
Robert was a benefactor of Rievaulx, Newminster, Kirkham, and the Templars.
He founded the leprosery of St Thomas the Martyr at Bolton, Northumberland.
He gave the manor of Ribston (West Riding of Yorkshire) to the knights templar, who established a commandery there. He also gave several houses in York to the same order.
Robert divided his estates between his two sons. The elder, William, received Helmsley, whilst his brother Robert was to hold Wark and estates in Scotland.
It was Robert de Roos, also known as Fursan, who rebuilt Helmsley Castle in stone after 1186; it is recorded in the Chartulary of Rievaulx Abbey that he 'raised the Castles of Helmislay and of Wark'. The core of the surviving castle dates from this period. Fursan levelled off the inner bank of the earthwork castle, replacing it with an enclosing stone curtain wall and round corner towers.
He died, or, as a Templar, retired from secular life, shortly before 23 Dec. 1226, when his son [William] did homage for his lands.
In February 1205/6 he proposed to make a pilgrimage to Jerusalem. In 1212 he was believed to have taken the "habit of religion" as a Knight Templar of Jerusalem, but in the following year was certainly in the King's employment.
28 Feb 1206: received licence, whenever he should take the cross, to pledge his lands for money to anyone of the king's subjects any time during the following three years (permission renewed 26 Feb 1207).
Towards the end of his life he joined the Knights Templar (the military religious order originally founded for the protection of pilgrims in the Holy Land, and later an order of great wealth).
Note He was buried at Temple Church, but Professor Saul's article (next section) states: "An effigy in that church sometimes associated with him dates from at least a generation later." The following description given, therefore, is of someone else.
"He was a member of the Order of Knights Templar. He died in 1226/7 and was buried 'in his proper habit' in the Knights' Church, or the New Temple in London, where his tomb may be seen. His effigy is described by Gough, in Sepulchral Monuments, as "the most elegant of all the figures in the Temple Church, representing a comly young knight in mail, and a flowing mantle with a kind of cowl; his hair neatly curled at the sides; his crown appears shaved. His hands are elevated in a praying posture, and on his left arm is a short, pointed shield charged with three water-bougets. He has on his left side a long sword, and the armor of his legs, which are crossed, has a ridge, or a seam up the front, continued over the knee. At his feet is a lion, and the whole figure measures six feet two inches..."
Magna Carta 800th Anniversary Biography
by Professor Nigel Saul
"Robert de Ros (c. 1182-1226/7), kinsman through marriage of Eustace de Vesci, and the son of Everard de Ros and Roese, née Trussebut, was a Yorkshire lord, the owner of extensive estates centring on Helmsley in the North Riding of Yorkshire and Wark-on-Tweed in Northumberland. He was married, at an unknown date, to Isabella, an illegitimate daughter of William the Lion, king of Scotland, and widow of Robert III de Brus.
"In the early 1200s Robert is found co-operating actively with King John, witnessing a number of his charters, chiefly at locations in northern England, and in 1203 assisting in the king’s defence of Normandy, where by descent from his mother he held the hereditary office of bailiff and constable of Bonneville-sur-Touques in the lower part of the duchy. In 1205, however, a year of rising political tension, there are signs that his relations with the king were worsening, and John ordered the seizure of his lands and, apparently shortly afterwards, had his son taken hostage. Robert, a little later, recovered his lands, but an indication that he might have been interested in leaving England is given by his acquisition of a licence to pledge his lands for crusading. It is not known, however, if he ever actually did embark for the East.
"In 1212 Robert seems to have entered a monastery, and on 15 May that year John handed over custody of his lands to one Philip de Ulcot. His monastic profession, however, cannot have lasted for long, for on 30 January 1213 John appointed him sheriff of Cumberland, and later in the same year he was one of the witnesses to John’s surrender of his kingdom to the pope. In 1215, as relations between the king and the baronial opposition worsened, John seems to have tried to keep Robert on his side, ordering one of his counsellors to try to secure the election of Robert’s aunt as abbess of Barking. By April, however, Robert was firmly on the baronial side, attending the baronial muster at Stamford and, after June, being nominated to the committee of twenty-five.
"When war between the king and his opponents broke out towards the end of the year, Robert was active on the baronial side, forfeiting his lands as a result and suffering the capture of his son at the battle of Lincoln in May 1217. After Louis returned to France, Robert submitted to the new government and recovered most, although not all, of his lands. He witnessed the third and definitive reissue of Magna Carta on 11 February 1225. Sometime before 1226 he retired to a monastery and he died either in that year or early in 1227. At some stage he was received into the ranks of the Templars and on his death he was buried in the Temple Church in London, where a few years earlier William Marshal, the one-time Regent had been buried. An effigy in that church sometimes associated with him dates from at least a generation later.
"Robert is an enigmatic individual who had close ties with Eustace de Vesci but did not openly join the rebellion until just before Runnymede. He probably felt a conflict between his sense of loyalty to his fellow Northerners and his obligation of obedience to the king."
1196: after a battle between men of Phillip Augustus and those of Richard I, Richard handed over to Robert's keeping Hugh de Chaumont, a wealthy knight and intimate friend of Phillip Augustus. Robert imprisoned him in his castle of Bonneville. But his servant, the keeper of the castle, William D'Epinay, was bribed into conniving at Hugh's escape. Richard, angry at the loss of so important a prisoner, ordered D'Epinay to be hanged, and imposed a fine of 1200 marks on his master. 240 marks of this were still unpaid on 29 Jan 1204 when King John remitted 100 marks.
Immediately after accession [April 1199], John sent Robert and others to William the Lion of Scotland, Robert's father-in-law, to arrange an interview between the two sovereigns for 20 Nov 1199.
November 1200: As the son-in-law of William the Lion, King of Scotland, he was of his escort into England November 1200, to do homage.
In succeeding years Robert witnessed several royal charters, chiefly in north England, but on 7 Oct 1203 was at Bonneville-sur-Touques, He might have been in John's service at Normandy later that year, returning to England before 22 Feb 1204, when he was at York.
Spring 1205: difficulty with John, possibly about the balance of his fine, and his lands were seized, but an order for their restoration was soon issued.
13 Feb 1207: For some reason, possibly on account of the arrears of his fine, his son Robert was in the king's hands as a hostage. Robert seems to have let prisoner Thomas de Bekering escape, and on 28 Dec 1207 was acquitted of a fine of 300 marks for his new offence.
10 Apr 1209: sent with others by the king to meet the king of Scotland.
1212: Robert seems to have assumed the monastic habit
15 May: John therefore handed over custody of his lands to Philip de Ulecot. (also "Oldcoates") His profession cannot have lasted long ...
30 Jan 1213: king committed to him the forest and county of Cumberland.
25 Feb 1213: on a commission to inquire into grievances for exactions of royal officers in Lincoln and York. Among other royal favors he received this year was a license to send across the seas a ship laden with wool and hides to bring back wine in exchange. He interceded with the king in favor of William of Aumale, his suzerain in Holderness, and got him safe-conduct as a preliminary to a reconciliation.
03 Oct 1213: a witness of John's surrender of the kingdom to the pope, and one of 12 men who tried to compel John to keep promises in favor of English church.
1214 - early 1215: continued in John's service as Sheriff of Cumberland
He was loyal and closely associated to King John, but was one of his most vigorous opponents in the matter of Magna Carta, being one of the 25 elected to see its provisions were obeyed.
10 Apr 1215: received several royal manors in Cumberland and Westmoreland. About the same time John, ordered John de Roches to do all that he could to secure the election of Robert's aunt as abbess of Barking, and in no wise permit the election of the sister of Robert Fitz Walter, one of the baronial leaders But John failed, despite these favours, to secure Ros's adherence in his struggle with the barons.
week following 19 April: According to Roger of Wendover, Ros was one of the chief "incentors of this pest" (i.e., the baronial resistance of the king) in the meeting of the magnates at Stamford. He was one of the 25 barons elected to promote observance of the Great Charter, and took part in the resistance against John after his absolution from his oath to the pope. Consequently, Innocent IV excommunicated him in January 1216.another piece of unsourced info said: For this he was excommunicated by Pope Innocent III.
1215: Wark Castle was burned by King John, since the owner Robert de Ros had signed Magna Carta. It was rebuilt and later held under royal control.
1216: After king's success in the north earlier in the year, a castle belonging to Robert was one of the only two that remained in the possession of the barons in the north.
27 Jan: John granted his lands to William, Earl of Aumale. He was summoned to deliver up Carlisle Castle, and expressed his readiness to do so, merely asking for a safe conduct for an interview, which the king promised.
12 Apr: John repeated offer but led to nothing. Robert held the government of Northumberland, and seems to have continued his resistance even after John died.
May 1217: son William was captured at Lincoln. Robert eventually submitted, and Henry III commanded his manors of Sowerby, Carleton, and Oulsby to be restored to him on 23 July 1218, and orders to different bailiffs of the king to allow him to hold his lands unmolested were issued on 22 Nov 1220.
Feb 1221: summoned to help beseige and destroy Skipsea Castle.
1222: seems to complain to the king that the King of Scotland was encroaching on English territory, and a commission of inquiry was appointed.
24 May: Whether the Sheriff of Cumberland, apparently Walter Bishop of Carlisle, delayed to restore his lands through jealousy, or they were seized again, their restoration was ordered again.
23 May 1222: king forbade same Sheriff of Cumberland to exact tallages from royal manors given to Robert.
06 Feb 1225: renewed order to give Robert seisin of these royal manors seems to indicate king's former orders disobeyed.
11 Feb: Robert witnessed the third reissue of the Great Charter.
26 Feb: Henry ordered barons of the exchequer to deduct revenues of the royal manors given to Robert de Ros from the county firm owed by Walter Bishop of Carlisle.
before 18 Jan 1227: Robert takes the monastic habit again.
He died that year and was buried in the Temple Church at London. In the modern era, there are reportedly no tombs or burials in Temple Church in central London. Only effigies can be seen there today. (See above.)
Are Helmsley Castle and Hamlake Manor the same place?
"He married Adeline l’Espec, co-heiress of her brother Walter l’Espec, founder of Rievaulx Abbey, and left a son, Robert de Ros the elder, who is well known for his benefactions to the newly founded community of Knights Templars. Everard de Ros, son of Robert de Ros, was like his father, specially charitable to the Templars, and Robert de Ros, surnamed Fursan, son of Everard, by Rose co-heiress of the Trussebuts, built the castles of Helmsley (anciently called Hamelac) in north Yorkshire, and Werke in Northumberland. He it was, too, who in 1217 gave “to God and the Blessed Mary and the brethren of the Soldiery of the Temple, my manor of Ribston, with the advowson of the Church of the same vill and the hamlet of Walshford with the mills of the same hamlet,” etc.
↑ Lewis (citation below) gives their marriage date as "circa February 1191" and names Isabel's mother as "Isabel de Avernal", with citations to Richardson, but Richardson does not include her mother's given name and gives their marriage as just "1191".

Re-review needed (the profile needs lots of editing)
Source Check: Finished check of Lewis against Richardson. Lots of "Citation needed" still.
The Rotuli de Dominabus of 1185 records “uxor Everardi de Ros que fuit filia Willelmi Trussebut…xxxv” and her land “in Strowestone”, adding that she had "ii filios, primogenitus est xiii annorum et terra eius est in custodia Ranulfi de Glanville".
The Chronicle of Melrose records the marriage in 1191 of "the king of Scots…his daughter Ysembel (the widow of Robert de Brus)" and "Robert de Ross" at Haddington.
Thanks Sunny! I checked Richardson's Royal Ancestry (Vol. IV, p 487) and the information in the profile matches what he has (1170-72 birth based on him being 13 in 1185 & of age in 1191 when he "had livery of his lands"). Looking at the fine print in RA, I don't see an IPM referenced, so I'm not sure where the 13 in 1185 came from.
I'm a bit baffled that the article by Professor Nigel Saul, Royal Holloway, University of London for the Magna Carta Trust and Richardson don't agree on dates (Saul's article does not elaborate on why he has b 1182; he also has marriage as 'date unknown'). Richardson speaks of her margaritum in relation with her 1191 m to Robert, so it seems that documentation would be his source for 1191, but that should have been available to Saul too.
In searching for information re: Gervasius, I came across an old post on Gen-Medieval, which is archived here: http://soc.genealogy.medieval.narkive.com/4YPG9drv/de-ros-roos-of-yorkshire. Basically someone posted in 2005 that Gervasius married a daughter of de Ros according to Pedigrees of the County Families of Yorkshire and West Riding, by Joseph Foster, published 1874. In 2007 another person asked if that was correct, to which John Ravilious replied, "While there certainly might be a Lowther-de Ros marriage, the chronology is a problem as given. Margaret de Brus, sister and coheiress of the last de Brus lord of Kendal, likely married Robert de Ros of Wark say 1240-1250, so it seems unlikely a son in law of theirs would have been active in 1217."
