Rooflight and skylight installation in Rivenhall

Rural work

Properties stand alone in open country, which means good access and real wind exposure. Access being easy keeps scaffold costs down and makes multiple units practical; exposure means the weathering detail needs executing properly.

Conversions

Agricultural conversions are common here and they remain the best rooflight candidates we see: large uninterrupted roof planes, almost no wall openings, and deep plans that are dark in the middle.

A run of roof windows along a slope lights such a space far better than one large unit, and on a listed conversion the flush conservation version is what gets agreed.

Older roofs

Clay pantile and plain tile over cut roofs and, on the older buildings, timber frames that have moved. Setting out follows the roof rather than a drawing.

Skylight and rooflight work we cover in Rivenhall

Roof lanterns, flat roof rooflights, roof windows, VELUX replacements, conservation units and sun tunnels, all surveyed before they are quoted. We also work in Witham, Silver End and Kelvedon.

A small parish either side of the A12

Rivenhall and Rivenhall End sit between Witham and Kelvedon, and the parish is a mixture: an older core around the church, scattered farms and cottages, twentieth century housing along the main routes, and a former airfield to the north.

Most work here is technical rather than heritage, and the two questions that decide a quotation are the roof structure and the access.

What happens on the day

A like for like replacement into a sound opening is a single day. A new opening in a tiled roof with making good runs to three or four days depending on the plastering. Most of that time is not spent on the roof.

Protection first. Floors covered, furniture moved or sheeted, and a dust barrier at the door. The making good is where the mess comes from rather than the roof, and containing it at the start is faster than cleaning up at the end.

Strip out and inspection. The lining comes off, the old unit is lifted out, and enough of the covering is removed to expose the frame. This is where the timber is inspected, and where we find decay we stop and tell you what it means before doing anything else.

Frame in. Set, checked for square and level in both directions, and fixed. Square matters more than anything else: a frame twisted by a few millimetres gives a sash that catches at one corner, and no amount of adjustment later fixes it.

Weathering. The underlay collar is dressed and lapped so water running down the underlay passes around the opening, then the flashing kit goes on and the covering is reinstated over it. That sequence is the whole job, and nearly every roof window that leaks leaks because a step was reversed.

Insulation collar and lining. The collar closes the gap between frame and structure. The lining goes back, plastered or trimmed depending on what was there.

Handover. Operation demonstrated, filter and cleaning position shown, guarantee paperwork left with you on the day.

We do not leave an opening uncovered overnight and we will not start a strip out if the forecast will not let us close it the same day.

Guarantee and aftercare

Ten years on our workmanship, alongside the manufacturer’s warranty on the product. Most rooflight problems are installation problems, which is why the first matters more, and where a unit fails under the manufacturer’s warranty on a job we did we handle that claim ourselves.

Routine care is short. Clean the gasket once a year so the sash seats properly, because grit on a compression seal both lets water past and makes an actuator work harder. Clean the filter at the top of the sash. Cycle any motorised unit fully a few times a year including in winter. And on an exposed roof, check the flashing and fixings every few years after a storm.

Choosing the glass

Two numbers get quoted for the same product and that is where comparing quotations goes wrong.

Centre pane U-value measures the glass away from the edges and ignores the spacer and the frame, which is exactly where heat escapes. It is always the better figure and it is what marketing quotes. Whole unit includes glass, spacer and frame weighted by area, is what the building experiences, and is what Building Regulations use. It is always worse, frequently by 0.4 or more.

Ask both installers for whole unit figures or you are comparing nothing.

Beyond the headline number, two things matter more than most people expect. A warm edge spacer rather than aluminium, because an aluminium bar conducts heat around the whole perimeter of every pane and shows as a band of condensation at the edge of the glass on cold mornings, which regularly gets mistaken for a failed unit. And solar control on south and west facing units, which costs a modest premium at the point of order and a great deal to change afterwards.

Triple glazing we would generally advise against. It takes the whole unit figure from about 1.2 to about 0.8, which is real and modest, while adding weight that affects an actuator, reducing daylight transmission, and costing substantially more. The same money on solar control glass and an insulated kerb does more for how the room feels.

Timescales and lead times

A like for like replacement into a sound opening is a single day. A new opening in a tiled roof with making good runs to three or four days depending on the plastering.

What lengthens a programme is the order rather than the work. Stock sizes are quick; made to measure units and lanterns run to several weeks. Where a trussed roof means a designed trimmer is needed, or where a converted agricultural building needs a structural check, that input comes before the order rather than alongside it.

The sensible sequence is survey, structural check where needed, permission where needed, order, then book the fitting to the delivery date. We would rather give a realistic date than an optimistic one.

Privacy and obscure glazing

On a dispersed rural parish overlooking is rarely the issue, and where privacy matters it is usually about a bathroom rather than a neighbour.

Obscure glazing solves it permanently without a blind. Several grades are available from lightly textured to fully opaque, it costs a modest premium at the point of order, and it cannot sensibly be added later because the labour and access are the same as replacing the whole unit.

Avoid it anywhere the view matters, because obscure glass gives light without any sense of sky.

On a side elevation facing a boundary, permitted development rules may require obscure glazing and restrict how far the unit opens. That is a legal requirement rather than a preference, and we check it at survey.
