AN INTRODUCTION / 05

Transform Your Loft Space with Professional Roofing and Structural Work

Add practical, usable space upstairs by converting your loft. We focus on the roofing and structural elements that make a conversion durable and compliant.

Short on space but don’t want to extend at ground level? Converting the loft often solves that. We focus on the roof and structural tasks a conversion requires: detailed surveys to check headroom and roof geometry, strengthening or replacing joists for a new floor, altering rafters for dormers or rooflights, and integrating coverings and flashings so the building remains watertight. After the survey we set out feasible options and provide a written scope for the roofing and load-bearing work needed.

Common Loft Conversion Types

Choosing the right conversion depends on how much extra space you need and what the roof allows. We deal with the structural and roofing elements for each type: forming dormer extensions, cutting in rooflights, rebuilding hip ends as gables, or extensive mansard rebuilds. Each approach changes headroom, access and drainage differently, so a measured survey and a clear scope for roofing and structural work are essential before committing.

01 / 04LOFT CONVERSIONS

Dormer Loft Conversions

Want substantially more floor area and headroom? A dormer conversion adds vertical extension and a window run for daylight. We carry out the roofing and structural tasks involved: cutting and reconfiguring rafters, building dormer cheeks and roofs, tying new flashings into existing coverings, and ensuring the new floor is adequately supported. After our survey we set out the required roof alterations and the work we will carry out to make the dormer weatherproof and structurally sound.

Rooflight Loft Conversions

Prefer daylight with minimal intervention? Rooflight conversions keep the existing roofline and add skylights to improve natural light and ventilation. We assess roof pitch and rafters to confirm window placement and how membranes and flashings must be upgraded. Work includes cutting openings where safe, installing modern flashing kits and renewing adjacent roof coverings to prevent leaks while the loft becomes brighter and more usable.

Hip-to-Gable Loft Conversions

Facing a hip end and need extra lateral space? A hip-to-gable conversion replaces the sloping hip with a vertical gable to create more usable loft area. We undertake the structural rebuilds at the eaves and rafters, reconstruct the roofline, tie in new coverings and check foundations where extra load-bearing walls are introduced. A measured survey is required so we can explain the roofing and support work we would carry out if the conversion is feasible.

Mansard Loft Conversions

Need the maximum internal volume and can accept substantial roof rebuilding? A mansard conversion reshapes the roof with steep sides and a flat or shallow top. We carry out the extensive carpentry, roof frame rebuilds and brickwork tie-ins required, plus the roof coverings, flashings and drainage work to make the new profile weatherproof. Because the external roof changes significantly, we set out the full roofing and structural scope after a detailed site survey and coordinate with the design team you appoint.

OUR PROCESS / FOUR STAGES

How the Work Progresses

Decided to proceed? The roof and structural stages follow a clear sequence: technical survey, a written roofing and load-bearing scope, coordination with your designer or engineer for drawings and calculations, then phased on-site work that keeps the building weatherproof. Dates are confirmed in writing after the survey and depend on scope, access, weather and materials.

  1. STAGE / 0101 — 04
    01

    Survey and Measured Assessment

    Contact us to arrange a measured survey that checks headroom, roof pitch, truss layout and load-bearing points. The assessment identifies where joists need strengthening, whether rafters must be altered, and how windows or dormers can be positioned. The survey report defines the roofing and structural scope we will price and carry out and highlights any party-wall or access issues to resolve before work starts.

  2. STAGE / 0202 — 04
    02

    Design Coordination and Structural Calculations

    Where drawings or calculations are required we work from the plans you or your designer provide and coordinate with structural engineers. We confirm roofing details, locations for flashings and gutters, and the structural interventions our trades will execute. While we do not provide planning or architectural design, we will explain the information building control or an engineer will expect and how our work fits those requirements.

  3. STAGE / 0303 — 04
    03

    On-Site Structural and Roofing Work

    When works begin on site we follow a phased approach that keeps the building weatherproof: make-weather measures, structural adaptations and roof alterations, then windows and coverings. Tasks include cutting dormer openings, reinforcing or replacing joists, rebuilding gable ends, and installing new roof coverings with correct flashings. We record the roofing work for building-control inspections where needed.

  4. STAGE / 0404 — 04

    Final Weatherproofing and Handover

    After the structural phases are complete we finish the external roofing elements — coverings, flashings, gutters and downpipes — so the conversion is watertight. We then provide a written summary of the roofing and structural work carried out and arrange any follow-up checks required by building control. Internal finishes are coordinated with your chosen trades so the space is ready once decoration and services are finished.

WHY CHOOSE RAPTOR / WHAT MATTERS

Why Proper Roofing and Structural Work Matters

For a lasting conversion the roofing and structural changes must be right from the start. We concentrate on safe roof alterations, correct load-bearing solutions and robust weatherproofing so the new room remains dry, thermally efficient and ready for building-control sign-off.

01

Structural Integrity First

Poorly adapted joists and rafters allow movement, sagging or water ingress over time. We strengthen the roof frame and floor structure where necessary, work from approved calculations when required, and use standard structural approaches so the new space stays stable and safe.

02

Weatherproofing and Drainage

Adding dormers, new rooflines or rooflights changes how water runs off the roof and where it collects. We install correct flashings, tie-ins and drainage adaptations and check gutters and downpipes so the conversion doesn't create leaks or overload existing runs, protecting internal finishes and avoiding recurring repairs.

03

Coordination with Building Control and Other Trades

Projects involving building-control inspections and several trades need careful sequencing to avoid rework. We coordinate with your structural engineer, designer and other contractors to deliver the roofing and load-bearing elements to the standards building control will inspect, keeping the roofing phases aligned with the wider programme.

INSIGHT / Insights on Loft Conversions

Understanding the Options for Your Palmers Green Home

Choosing between conversion types, focus on what each method delivers for space, light and structural impact. Look at the trade-offs so you can pick the option that matches your brief and the realities of your roof.

01 / EXPLAINED

Dormer vs Rooflight Conversions: Space and Structure

Dormers usually win where usable floor space and comfortable headroom are the priority. They create vertical walls and larger windows, making the upstairs room functional for sleeping or living rather than storage. We carry out the roofing and structural interventions a dormer needs: cutting and reconfiguring rafters, building cheeks and roofs, and supporting the new floor with strengthened joists. By contrast, rooflight conversions keep the existing roofline and primarily add daylight; they suit shallower lofts or situations where visible extensions are restricted, but they deliver less extra floor area and need careful flashing and placement.

02 / EXPLAINED

Structural Considerations for Hip-to-Gable and Mansard

For a substantial increase in loft volume, hip-to-gable and mansard conversions are the most productive but also the most intrusive. Hip-to-gable work replaces a sloping hip with a vertical gable, generating lateral space but requiring roof-frame rebuilds and checks on wall and foundation loads; we assess the structure, remove the hip, construct the new gable and tie new coverings into existing slates or tiles. Mansards reshape the roof to steep slopes with a flat top, maximising cubic space but demanding significant carpentry, brickwork and a full renewal of coverings and flashings. Both require careful structural checks and we work from your engineer’s calculations when supplied.

03 / EXPLAINED

Planning and Regulatory Insights

Planning and building regulations are separate. Many loft conversions fall under permitted development but visible roofline changes, large volume increases or local restrictions can trigger the need for planning permission. Building regulations apply to every conversion and cover structural stability, fire separation, insulation, ventilation, sound insulation and safe access via an appropriate staircase. We prepare the roofing and structural work to meet the outcomes building control inspects — properly supported floors and weatherproof roof tie-ins — and explain the roofing and structural evidence building control will expect.

QUESTIONS / LOFT CONVERSIONS

Frequently Asked Questions

Thinking about a conversion? Below are common questions on feasibility, access, risks and what happens when you enquire. Each answer explains the roofing and structural aspects we focus on and sensible next steps.

ASK ANOTHER QUESTION
01How do I know if my loft has enough headroom for a conversion?

Limited usable height above the existing joists can rule out certain conversions. We begin with a measured survey to record ridge height, ceiling levels and rafter layout so we can advise whether rooflights, a dormer or a hip-to-gable would create sufficient headroom and what structural changes would be necessary.

02Will a loft conversion affect my roof’s drainage or gutters?

Yes — adding dormers, mansards or rooflights can change how water runs off the roof and where gutters collect it. We always assess drainage during the survey and include any necessary guttering, downpipe or flashing upgrades in the roofing scope so new rooflines discharge correctly and avoid water pooling or splash-back against walls.

03Do I need a structural engineer for a loft conversion?

Major structural changes — significant joist strengthening, removal of load-bearing elements or new support walls — typically require structural calculations. We work from the engineer’s drawings when supplied and will identify during the survey whether engineer-calculated details are required; we do not produce structural designs ourselves.

04Can I remain in the house during the loft conversion work?

Many homeowners stay in their properties during conversion work, but you should expect noise, deliveries and scaffolding that may restrict parking or garden access. We discuss safe access, protected walkways and site boundaries before starting so you can plan which areas to avoid and how trades will use shared spaces.

05What access and scaffolding will be needed for a loft conversion?

Scaffolding is commonly required to provide safe access for roofing, dormer construction and installing windows. During the survey we note access constraints and propose the most practical scaffold layout and working platforms. We include the roofing tie-ins and external work that scaffolding enables in our written scope so you know what to expect.

06What should I send when I first contact you about a loft conversion?

Start by sending a few photographs: an external shot of the roof from the street or garden, an internal picture of the loft showing joists and any existing insulation, and the property postcode. We will use that information to advise whether a measured survey is needed and outline the roofing and structural checks the survey will cover.
