RAPTOR ROOFING & CONSTRUCTION LTD
When extra living space is needed without extending outwards, a loft conversion turns unused roof space into a bedroom, office or family room. We manage the roofing, structural carpentry and brickwork that create a weatherproof shell ready for internal services. Start by sending basic property details so we can advise which conversion types suit your home and whether a site assessment is necessary.
AN INTRODUCTION / 05
Considering a loft conversion in Hitchin? Decide which option gives you the space you need and what to prepare before you contact us.
Want an extra bedroom, home office or playroom without changing your house footprint? We concentrate on the roofing, timber carpentry and brickwork that form the shell of most conversions, making the roof watertight and the new room structurally secure. Before you contact us, note house type, any existing loft access, internal headroom and take clear photos of the loft and roof slopes to speed an initial assessment.

Match the conversion type to your headroom, roof form and tolerance for external change. We carry out the roofing work, joinery and brick or blockwork required for dormers, rooflights, hip-to-gable and mansard conversions and coordinate the interfaces so the shell hands over ready for first-fix services and finishes.
A dormer provides more usable floor area and full head height by creating a vertical-sided box from the existing roof slope. We construct the timber frame, tie new dormer walls into the roof, complete brick or blockwork where required and flash junctions to keep the roof watertight before handing the shell to interior trades for insulation and first fixes.
ENQUIRE ABOUT THIS SERVICEPreserving the external roofline often leads homeowners to choose rooflight conversions that bring daylight in without building out. We cut and reinforce openings in the rafters where necessary, fit upstands and flashings for each rooflight, and ensure insulation and ventilation details around the aperture prevent cold bridges and condensation.
ENQUIRE ABOUT THIS SERVICEWhere a hip end limits the usable width, a hip-to-gable conversion replaces the sloping hip with a vertical gable to widen the internal plan. We carry out the structural alterations to the existing roof frame, form the new gable wall in block or brick and integrate new roof timbers and coverings so the enlarged space is weatherproof and ready for finishing trades.
ENQUIRE ABOUT THIS SERVICENear full-height accommodation comes from a mansard conversion that replaces a roof slope with steep, near-vertical sides and a shallow top to maximise floor area. We undertake the brickwork and timber framing, form parapets and install parapet flashings and roof coverings so the new storey is watertight and built to the structural specification.
ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
Follow a staged route from idea to a usable room: initial checks, structural design, on-site structural and roofing work, then handover to the trades that finish the interior. We focus on the roofing, carpentry and masonry phases and note which further services you will need to complete the project.
Begin by measuring internal headroom and photographing the loft and roof from inside and out. We review those details and advise whether a measured survey or a structural inspection is required to check joists, rafters and the ridge; where needed, a structural engineer provides calculations that we work to and will identify which parts of the structure need strengthening.
When new openings, dormer frames or altered roof geometry are required, the structural timberwork and masonry come first. We install new trusses or strengthen existing rafters, build dormer walls or gables in block or brick, and form the stair opening and supports so the shell meets the building-regulation specifications provided with the design.
To make the shell watertight, coverings, flashings and insulation are fitted promptly after the structural frame is in place. We install roof coverings, attach upstands and fit lead or flashing where dormers meet the main roof, and ensure rooflights are sealed correctly so internal trades inherit a dry, thermally sound space.
Once the structural shell is finished we form stair openings, install timber supports for the stair and complete external masonry and roof details so internal trades can begin. We coordinate with electricians, plumbers and plasterers on access points and handover dates; finishing works are then carried out by specialist contractors.
WHY CHOOSE RAPTOR / WHAT MATTERS
A clear structural handover begins with concentrating on the roofing, carpentry and brickwork stages. We make the shell waterproof and structurally safe, and set out what is included in our scope so responsibilities are clear when you receive the quote.
Structural roof alterations and timber framing control how a converted loft performs under load and in wet weather. We carry out rafter and truss work, dormer and gable framing, plus roof covering installations so the shell behaves correctly and reduces surprises once internal trades begin.
Strong joinery and brickwork tie new dormer walls, gables and mansards into the existing building to form a robust envelope. We install structural timber stair supports and form block or brick walls to specification so the new room is ready for insulation and internal finishes.
For clarity at quote stage, we set out in writing which structural stages we complete and where other trades take over. That written scope avoids disputes about first-fix services, helps you budget for electrics and plumbing, and notes access and scaffolding requirements so you know what to expect on site.
INSIGHT / Loft Conversions in Hitchin
Deciding between dormer, rooflight, hip-to-gable or mansard should be driven by headroom, the amount of external change you will accept and the usable floor area you need.
Dormer conversions create a clear rectangular room with larger windows, improving both floor area and head height. They suit homeowners who want practical layouts for bedrooms or en-suites because the vertical face allows full-height windows and easier furniture placement; on site we cut into rafters where required, build the dormer frame, tie it into the roof and finish external brick or cladding and flashing details.
Rooflight conversions keep the roofline largely unchanged while bringing daylight into a converted loft, provided there is sufficient standing headroom. We create correctly sized openings, strengthen surrounding rafters where necessary and fit upstands and flashings so the roof membrane remains intact; proper insulation and ventilation around rooflights prevents cold bridges and condensation.
Major increases in floor area come from hip-to-gable and mansard conversions that materially alter the roof shape to create more internal volume. We form new gable or parapet walls, rework roof timbers and install parapet flashings and roof coverings so the new storey is weatherproof, delivering the shell work to structural specifications and coordinating with design teams and other trades.

QUESTIONS / LOFT CONVERSIONS
Questions about feasibility, regulations or how the work is staged are common; the answers below cover typical issues, risks to watch for and what information we will need from you during the initial enquiry.
ASK ANOTHER QUESTIONTo set realistic expectations a site survey and final design are required. Project length is governed by scope, access, the condition of existing timbers and whether structural strengthening or planning permissions are needed; we review photos first to indicate if a measured survey and structural design will be necessary to produce a reliable programme.
Planning rules vary locally and many loft conversions sit within Permitted Development limits, though exceptions apply in conservation areas or where external changes exceed set limits. Tell us about any conservation-area status when you enquire so we can factor that into our initial advice and the need to consult the local planning authority.
Headroom is assessed by measuring the standing height from the existing ceiling joists to the underside of the ridge and by checking usable dimensions against the chosen conversion type and building-regulation requirements. Send your measurements and photos and we will advise whether a roof-raising, dormer or rooflight approach is likely to meet your needs and regulatory criteria.
For completion of the structural shell we carry out the roofing, carpentry and masonry phases that make the space weatherproof and safe. Electrical, plumbing, plastering and decorating are normally supplied by other specialist contractors; we coordinate handover points and can suggest contacts where helpful, but those services are usually contracted separately from the structural work.
Choosing a conversion comes down to internal headroom, roof shape, the level of external change you will accept and the room layout you need. Dormers increase floor area; rooflights minimise external change but need sufficient headroom; hip-to-gable and mansard conversions create the most space but involve major structural and masonry work. Send photos and measurements so we can recommend the most practical options for your situation.
Disruption during structural stages includes noise, scaffold and roof access; we plan work in stages so the roof is made watertight early and internal disturbance is reduced afterward. We outline scaffold and access requirements when discussing your quote so you can prepare for the works.
