Firefighters spent all night tackling a roof fire at a home in Hurley.
The roof of a semi-detached house was destroyed but fire crews prevented the blaze spreading to any nearby homes.
Two appliances from Maidenhead were called out to Shepherds Close at 3.18am.
They were joined by the aerial ladder platform from Slough and a crew from Wargrave.
One jet, two hose reels and six sets of breathing apparatus were used to tackle the fire.
Seven people had managed to escape before the firefighters arrived, two were taken to hospital by ambulance.
An off-duty crew manager from Slough, who lived in the road, was able to give the crews a run down of what had happened.
Matthew Weldon, crew manager at Maidenhead, said: "When we turned up all the family were out.
"The fire had gone through the windows and was going through the roof as we arrived. There was a lot of smoke, the first floor and roof were well alight."
Firefighter were due to re-inspect the property this morning.
A Royal Berkshire Fire and Rescue spokesman said: "The family did have working smoke alarms, this raised the alarm and allowed the family to escape rapidly developing fire."
