The covering is opened up, the rafters are trimmed and a structural opening formed, the window is set to the correct upstand, and the manufacturer's flashing kit is dressed into the tiles or slates so water is carried around and away from the frame. Inside, the reveal is boarded and squared ready for decoration. We fit new windows into existing roofs, swap tired units for new ones, and install rooflights as part of a full re-roof. ### Who it's for Homeowners in Bradford and across Yorkshire converting or brightening a loft, landing, bathroom or box room. Landlords needing light and ventilation to satisfy a letting standard. Anyone whose existing roof window is misting, sticking, draughty or leaking at the flashing. ### When you need it You are converting a loft, the top floor is permanently dark, condensation is sitting in a bathroom with no ventilation, or an older roof window has started to let water past the flashing. A re-roof is also the cheapest possible moment to add or replace roof windows, because the covering is already off and the scaffold is already up. ### Why it needs a roofer Almost every leaking roof window we are called to is leaking at the flashing rather than through the unit. Sealant instead of a flashing kit, the wrong kit for a deep-profile tile, or an upstand set too low will all leak eventually. We match the kit to the covering, dress it properly, and leave the inside ready to decorate rather than ready to argue about. What ignoring it costs ## Left alone, thisgets more expensive A roof window installed badly does not fail dramatically. It stains a reveal, rots a lining and quietly soaks the insulation around it. ### How the damage escalates - Water tracking down the frame soaks the plasterboard reveal, so the first sign is a stained ceiling corner rather than a drip you can see. - A window set too low in the roof plane holds water against the frame, and repeated wetting rots the timber trimmers around the opening. - Sealant used instead of a proper flashing kit lasts a couple of seasons, then shrinks and cracks, usually during the first hard winter. - Cutting a rafter without trimming the opening properly weakens the roof structure at exactly the point it has been opened up. - A misted double-glazed unit is not a leak in the glass, it is a failed seal, and it will not clear on its own. ### Mistakes that make it worse - Having a general builder cut the hole and 'flash it in' with mortar or mastic rather than the manufacturer's kit. - Choosing a window size to suit the view rather than the rafter spacing, which turns a straightforward fit into unnecessary structural work. - Fitting a roof window into a covering that is already at the end of its life, so the roof gets stripped a year later anyway. - Leaving the internal reveal unfinished, which is where most of the complaints about roof windows actually come from. - Skipping ventilation planning in a bathroom, so the window fixes the light and does nothing about the condensation. Our process ## Five steps fromfirst call to sign-off - 01 ### Free assessment We look at the roof covering, the pitch, the rafter spacing and the room below, and tell you what size and type of window will actually fit without unnecessary structural work. - 02 ### Written detailed quotation You get the window type, the flashing kit, any structural trimming, access and internal finishing set out in writing before anything is ordered. No 'from' prices. - 03 ### Access and opening up Access is set up safely, the covering is opened, the rafters are trimmed and the opening is framed to take the window squarely. - 04 ### Fit and weather The window is set to the correct upstand and the manufacturer's flashing kit is dressed into the tiles or slates so the roof, not the sealant, keeps water out. The opening is never left unweathered overnight. - 05 ### Finish and sign-off The internal reveal is boarded and squared ready for decoration, the site is cleared, and we walk the finished job with you before the final payment is taken. What you get ## Specific outcomes,not vague promises ### Daylight where there was none A single well-placed roof window transforms a loft or landing far more than an extra light fitting ever will, and it costs less than moving a wall. ### Ventilation that fixes condensation An opening roof window gives a bathroom or loft a real air path, which deals with the cause of condensation instead of wiping the symptom off the glass. ### Weathered by a roofer The flashing kit is matched to your covering and dressed in properly, which is the difference between a roof window that lasts decades and one that stains the reveal by spring. ### Cheapest during a re-roof If the roof is being stripped anyway, adding or replacing roof windows at the same time saves the access, the disruption and a second set of costs later. In detail ## Materials, methodsand where they apply Roof window work spans three quite different jobs: a new opening in an existing roof, a like-for-like replacement of a failed unit, and rooflights installed as part of a re-roof. Each has its own detailing, and the quote says which one you are getting. ### Materials we use - Velux centre-pivot and top-hung roof windows in timber or polyurethane finish, chosen to suit the room and the reach. - Manufacturer flashing kits matched to the covering: slate and low-profile kits, deep-profile tile kits, and combination kits for multiple windows. - Insulation collars and underfelt collars so the junction between window and roof is sealed and insulated, not just covered. - Treated timber trimmers for structural openings, sized to the span and the rafter spacing. - Breathable membrane and battens where the surrounding covering has to be re-formed around the opening. ### How we do the work - Setting out from inside so the window lands where the room needs it, then transferring the opening accurately to the roof plane. - Trimming rafters with doubled trimmers where a rafter has to be cut, so the structure around the opening is stronger than what was removed. - Setting the window to the correct upstand above the covering, which is the single most common thing that is got wrong. - Dressing the flashing kit into the tiles or slates course by course so water is deflected around and below the frame. - Boarding and squaring the internal reveal, with the head and sill splayed where that improves light spread into the room. ### Variations of this service New roof window in an existing roofThe full job: opening formed, rafters trimmed, window fitted, flashed and finished internally. Usually a one to two day job per window depending on access and covering. Replacing an existing roof windowOlder units that mist, stick, draught or leak are swapped for a new window and a new flashing kit. Replacing the kit as well as the unit is what stops the same leak returning. Rooflights during a re-roofFitted while the covering is off, with membrane, battens and flashings formed around the opening as part of the new roof rather than cut into it afterwards. Multiple windows and combinationsTwo or more windows side by side or stacked, using combination flashing kits so the gap between them is weathered correctly rather than filled. ### Situations this applies to - Loft conversions and loft rooms that need daylight and an escape or ventilation route. - Dark top-floor landings and stairwells in Victorian and Edwardian terraces. - Bathrooms and en-suites in the roof space where condensation is the real problem. - Home offices and box rooms where a dormer is not practical or not wanted. - Properties where an existing roof window has failed and the reveal is already staining. ### Residential and commercial Predominantly residential across Bradford, Doncaster and the wider Yorkshire area: terraces, semis, detached houses and bungalows, plus landlord and HMO stock where light and ventilation standards have to be met. Light commercial rooflight work follows the same weathering principles. Roofserve Ltd is fully insured, £2,000,000 public liability and £10,000,000 employers' liability.

Questions answered ## Velux roof windowsFAQs Cost, timescales, guarantees and how the work is actually carried out. If your question isn't here, call Jamie on 07947 494364 , open 24 hours, 7 days a week. Do you supply the Velux window or do I?+−Either. Most customers have us supply it so the window and the correct flashing kit arrive together, but we will happily fit a unit you have already bought if the kit matches your covering. Can a roof window be fitted without scaffolding?+−Access is assessed and priced honestly. Some installations are safely reachable from a tower, others need scaffold. It is set out in the quotation rather than added later. How long does it take to fit one?+−A single window in an existing roof is typically one to two days including the internal reveal, depending on access, covering and whether a rafter needs trimming. Will the roof be left open overnight?+−No. The opening is weathered before we leave site each day. My existing roof window leaks. Does it need replacing?+−Not always. Most roof window leaks are flashing failures rather than unit failures. We will tell you honestly whether re-flashing solves it or whether the unit itself has gone. The glass is misted up inside. Can that be repaired?+−That is a failed double-glazed seal, and the practical fix is a new unit or a new window rather than a repair. Do I need building regulations approval?+−A straightforward like-for-like roof window usually does not, but a new opening, a loft conversion or anything involving structural alteration can. Where Building Control involvement is required we liaise with them. Can you fit roof windows during my re-roof?+−Yes, and that is the cheapest time to do it. The covering is off and the access is already in place. Do you plaster the inside afterwards?+−We board and square the reveal ready for decoration. Full plastering and decorating is quoted separately if you want it included. Which areas do you cover?+−Bradford and the surrounding West Yorkshire towns, plus South, North and East Yorkshire, including Leeds, Wakefield, Doncaster, Rotherham, Barnsley, Sheffield and Selby.
