I recently moved into a house that has a roof with raised tie trusses and no internal supporting walls. I wanted to use the loft as storage but the small dimensions of the roof ties are concerning for anything other than what nature intended. I have recently also had a survey done on the property to fit a heat pump, but would need the water cylinder to be located in the loft BUT I'm unsure as to what method can be applied to strengthen the roof ties as the wall plate is much lower and not accessible to bear weight and with no internal LB walls this is a 20ft span with nothing to bear against. How are raised tie roof trusses strengthened for a loft conversion? One carpenter mentioned about sistering larger joists and bolting them against the existing rafters with additional struts from rafter to joists along the edges, and another said about lowering all ceilings to implement a wall plate to wall plate span and using RSJs but that is a lot of work for a storage room. Any ideas? -
Hi all, So plan is to creat a new liviing space in the loft. Already have about 3.3m to the apex. We would like more head height at the front and back though (means we can have 2 extra rooms due to improved access). So the plan: 1 Remove existing roof, 2 Raise the walls (2 options here) Option 1 - raise front and back and reduce the roof angle Option 2 - raise all walls and chimney and keep current roof angle. 3 Install three dormer windows at the front and three skylights at the back (north facing) 4 New trusses either scissors or raised tie across 5m span of the house. That's it in brief - I'm looking for thoughts and experiences on trusses, type, angles, and any other considerations anyone had to make. Just to note, everything removed will be used in a future part of this project. There is some really nice wood coming out of the roof.
