Skylight Installation in Rowhedge

Rowhedge sits on the Colne opposite Wivenhoe, a village that built and launched ships for generations and then, when that trade ended, turned the shipyard into housing. The result is a waterfront of contemporary homes, a lot of glass and clean modern rooflines, set right at the edge of the water, with the older village core behind them. It looks new, and much of it is, but the estuary in front of it has not changed, and that is the part a rooflight specification has to get right.

It is 16.3 miles from Ipswich in a straight line, around thirty-five minutes down the A12 and round Colchester. Close enough for an easy survey and return.

New build on the water’s edge is not a corrosion-free zone

There is a natural assumption that a modern house needs no thought about salt, and on most modern stock that is fair. Right on an estuary it is not. The contemporary homes along the Rowhedge waterfront sit as close to tidal saline water as any period cottage on the coast, and the moderate salt in the air off the Colne treats a new fixing exactly as it treats an old one. A developer’s contractor fitting a run of rooflights to a tight programme very often uses the standard A2 stainless kit that comes in the box, which is correct for an inland site and marginal on the water’s edge.

So when we work on this stock, whether fitting a new unit or replacing a developer-era one, we specify for where the house actually stands: upgraded stainless fixings on the water-facing slopes, a sensible step up from the standard kit. This is estuarine exposure, moderate salt, not the open coast, so it does not need the full marine 316L build we keep for the sea. It does need more than the default.

Contemporary rooflines bring more glass, and flatter roofs

The modern waterfront designs here tend to make a feature of daylight: large fixed rooflights, roof lanterns over open-plan living space, and low-pitch or flat roof sections that a period cottage never had. That changes the detail.

• Flat and low-pitch roofs need a designed fall. A flat-roof rooflight sits on a kerb, and the kerb has to create a fall so water clears rather than sits. Ponding around a unit is the commonest cause of a leak on this kind of roof, and it is a detailing failure, not a product failure.
• Large glazed units are heavier and windier. A big fixed light on an exposed waterfront carries real wind load, so the fixings and the kerb are sized for it rather than assumed.
• More glass means the glass specification matters more. In an open-plan waterfront room the rooflights are a large part of the thermal envelope, so a warm-edge spacer and a thermally broken frame are worth the spend.

The older village core

Behind the waterfront the original village has more traditional stock, and there the job is the familiar one: a pitched roof skylight installation into an older covering, or a VELUX, Keylite or Roto unit into a converted roof, with upgraded fixings on any slope that faces the water. The exposure grade is the same across the village, estuarine and moderate, whether the roof is thirty years old or a hundred and thirty.

Two eras on one village map

Rowhedge reads as two settlements laid over each other. The older core is a Victorian and earlier village, the streets that once served the shipyard, with period cottages, terraces and the odd larger house on tight lanes running back from the water. The waterfront is the opposite: a 2000s and later redevelopment of the shipyard site, contemporary houses and apartments built to a modern specification. Between them the roof in front of you could be a hundred and fifty years old or fifteen, and almost everything about the job follows from which one it is.

The core carries a conservation area with a scatter of listed buildings within it, so on the old lanes a rooflight on a visible slope can need planning and a listed cottage needs consent, whichever slope you use. The redeveloped waterfront carries no such designation and is a technical job from start to finish. It is worth knowing which side of that line the house sits on before anything else, because it decides whether the first conversation is about consent or purely about the roof.

Cut roofs on the core, engineered roofs on the waterfront

Structurally the two eras could hardly be more different. The old core has hand-cut roofs, framed on site, often in modest softwood and sometimes carrying old repairs, and an opening there is formed by reading the existing frame and trimming carefully back to sound timber between the rafters. The waterfront houses have modern engineered roofs, trusses or attic trusses at close centres designed as a system, so the rooflight is planned to the layout and sits in the designed gap rather than being cut through structure.

On the older roofs the width of the opening is limited by what the frame allows. On the newer ones it is limited by the truss spacing, and where a wider unit is wanted it means a designed and supported alteration rather than a quick cut. Neither is harder in the abstract, but they are priced differently, and the survey is where that gets settled honestly rather than guessed.

What the survey checks across both

Whatever the era, the survey works through the same short list and reaches a different answer on each roof. The timber comes first. On a Victorian cottage the rafters may be original, so a soft or split member is found before a unit is fixed to it, while on the waterfront the concern is less the age of the wood and more that a fast developer build left the deck and kerb detail sound. The covering comes next, because the flashing follows it: plain tile or slate on the old core, and a mix of modern tile, slate-effect and low-pitch membrane on the waterfront, each needing its own flashing. Then the fall on any flat section, the upstand height, the aperture size, and on every water-facing slope the fixing grade for the moderate estuary salt. One checklist, two quite different roofs.

Access: tight lanes and open quays

Getting to the roof is its own question, and here it runs the opposite way to the exposure. The old core is the harder access: narrow lanes down to the water, limited frontage, and not always an obvious place to stand a scaffold, so where the tower goes and how material reaches the roof is worked out at survey rather than assumed. The waterfront is generally easier ground, with more room around the newer houses, though a plot right on the quay edge has its own limit where the hard standing stops at the water. Either way the access plan is part of the quote, because a plan that ignores it is the thing that comes unstuck on the first morning.

What we fit here

On the modern waterfront, large flat roof rooflights on properly detailed kerbs and roof lanterns over open-plan space are the common jobs, both specified for the wind and the moderate estuary salt. The glazing numbers that matter in a glassy modern room are set out on energy efficient skylight installation.

Getting a price in Rowhedge

Every job is surveyed on the roof and priced once in writing, and the figure holds unless the specification changes. Installers with 25 years in the trade, a 10-year workmanship guarantee, installed to current Building Regulations. We replace failed units rather than patch them.

We cover the same estuary across the water at Wivenhoe, upriver at Alresford, and next door at Colchester. The full list is on areas we cover.
