C&J Construction & Roofing LTD converts lofts and builds dormers across West Yorkshire. A loft conversion is usually the cheapest way to add a bedroom to a house, because the roof, the walls and the foundations are already there. Our roofing background means the dormer and the new roof detailing are done by the same people who build the room.

The three things that decide whether a loft can be converted are head height, roof pitch and the type of roof structure. Traditional cut roofs with purlins convert easily. Trussed rafter roofs need the webs cutting out and new steels and floor joists installing, which is more involved but very often still possible.

What a conversion from us includes:

  • Feasibility check on head height, pitch and structure before you commit
  • New steel beams and floor structure independent of the ceiling below
  • Dormer construction, flat roof or pitched, or rear box dormer
  • Velux and roof windows fitted and flashed correctly
  • Staircase designed and installed to building regulations
  • Insulation to current standards in roof slopes, dormer cheeks and floor
  • Fire protection, fire doors and mains linked smoke alarms as required
  • Plastering, electrics, heating, and en suite plumbing where you want one
  • Building control inspections and completion certificate

We also carry out hip to gable conversions, which is the usual way to gain usable width on a semi detached or end terrace.

Common questions

Questions about loft and dormer conversions

If your question is not answered here, call 07927 976489 and ask.

Is my loft high enough to convert?

As a rule of thumb you want around 2.2 metres from the top of the existing ceiling joist to the underside of the ridge, measured before any work. Less than that is not automatically a no, but it changes the options. We will measure it for you free of charge.Do I need planning permission for a loft conversion? | Many loft conversions and rear dormers are permitted development within volume limits, but front facing dormers, conservation areas, flats and listed buildings usually need permission. Building regulations approval is always required, whatever the planning position.Can a room in the loft be called a bedroom? | Only if it meets building regulations, including the staircase, head height, fire escape route and fire protection. A boarded loft with a ladder cannot be marketed as a bedroom. Everything we build is signed off by building control so it counts.

Customer feedback

What our customers say

5 out of 5 from 5 reviews left on Facebook by customers across West Yorkshire.

  • We recently had our roof replaced by Connor and his team, and I honestly could not recommend them highly enough. From the very beginning, Connor was friendly and professional. Communication was excellent throughout the whole job. Any questions were answered quickly, and we were always kept informed about what was happening. The work was completed much quicker than we expected without compromising on quality, and the finished roof looks fantastic. The team worked hard, were respectful of our property, and left everything clean and tidy when they finished. Thank you to Connor and everyone involved for doing such a great job.

  • The work done was excellent. Turned up on time, worked all day, left the job tidy every day and the final finish was more than we expected. First class workers.
