Rooflight and skylight installation in Harwich

The old town

Tightly packed historic streets, listed buildings, and a conservation area over the core. Roofs are small, steep and closely overlooked, often in clay pantile.

A flush conservation rooflight is the only product likely to be agreed here, and on a listed building it is a listed building consent question, which is a different and slower process than permitted development. Access is genuinely difficult in the old streets and it belongs in the quotation.

Exposure

Harwich sits on a headland between the Stour and the Orwell with the North Sea beyond. Marine grade coatings, stainless fixings, and weathering details executed properly rather than adequately. Wind driven rain here tests everything.

The rest of the town

Beyond the old town and towards Dovercourt the stock is more ordinary: Victorian terraces, inter-war and post-war housing, and the usual rooflight and roof window work.

Skylight and rooflight work we cover in Harwich

Roof lanterns, flat roof rooflights, roof windows, VELUX replacements, conservation units and sun tunnels, all surveyed before they are quoted. We also work in Dovercourt, Walton-on-the-Naze and Manningtree.

Two towns, one name

Harwich divides sharply for our purposes. There is the old town on the peninsula, tight, historic and heavily designated, with some of the best surviving Georgian and earlier fabric on the Essex coast. And there is the twentieth century housing that runs back from it toward Dovercourt and Parkeston.

Both are exposed. The peninsula is one of the most weather beaten inhabited positions in the county, and that shapes specification as much as the designation does.

Making an application that works

Conservation officers in a town like this see a great many vague applications. A precise one gets a faster and better answer, and most of the delay people experience is caused by material that was missing rather than by a proposal that was wrong.

Name the product. Manufacturer, model and size, not a description of a rooflight in general terms.

Include the section drawing. The manufacturer’s detail showing exactly how far the unit stands above the plane of the covering. This answers the question the officer actually cares about, and its absence is the single most common reason an application sits.

Show it on an elevation. Not only on a plan. Describe honestly what is visible from where. A rear slope screened by the ridge from every public vantage point is a much easier case than the same unit at the front, and saying so plainly helps rather than hurts.

Frame a replacement correctly. Where an existing modern rooflight or plastic dome is being swapped for a conservation unit, say so explicitly. That is a heritage improvement.

We prepare this material as part of the job: the survey, the product drawing and a clear written description. It is not a planning consultancy and we do not charge as one, but it covers most domestic applications in the old town.

Timescales

Consent is the long part, not the fitting. A listed building consent application runs to months, and a conservation rooflight in a non standard size is manufactured to order with several weeks on top. Start the application first, order the unit second, and book the fitting to the delivery date rather than hoping.

Specifying for the peninsula

Beyond the consent question, the specification here should reflect one of the most exposed positions in Essex rather than repeat what would be fitted five miles inland.

Stainless fixings throughout. Salt air corrodes plated fixings within a few years, and once a fixing has gone the flashing it held is loose. The cost difference is trivial and it cannot be corrected later without opening the work up.

A high durability exterior finish. Aluminium clad timber suits exposed positions particularly well, because the cladding takes the weather and the timber behind it stays dry. On a steel conservation unit, check the powder coating every few years.

Weathering sized for driving rain. Wind driven water is pushed under a covering rather than running down it, so the underlay collar and the flashing kit carry almost the entire burden. A universal kit adequate in a sheltered position will let water past here within a couple of winters.

Wind loading checked against the site, particularly on larger units and anything that opens, because an open sash is a sail.

Blinds and shading

Worth deciding before the unit is ordered, because it affects which product to choose.

Mass market roof windows have a full accessory range of blinds that clip to the frame: blackout, pleated, venetian and external awnings. They fit exactly and cost far less than a made to measure blind fitted to a reveal. Steel conservation units, the sort required on listed and Article 4 properties in the old town, generally do not, so blinds become a separate made to measure item.

Internal blinds control light and privacy and do relatively little about heat, because the sun has already passed through the glass before the blind stops it. An external awning intercepts heat outside the glass and is far more effective in summer, though on this peninsula an external blind needs to be robust and properly fixed because of the wind.

Where a blackout blind is wanted over a bedroom, order it with the window.

What to send us

A photograph of the roof, one of the frontage showing the street and the access, and the address so we can check the listing and conservation position ourselves. For a replacement, photograph the data plate on the sash rather than measuring.

Tell us whether there is side access to the rear. In the old town that single fact changes the shape of the quotation more than the choice of unit does, because it decides whether scaffold and materials come down a side passage or through the house, and whether a highway licence is needed.

If the property is a flat, say so at the outset. Flats have no permitted development rights at all, so any rooflight needs a planning application and in practice the freeholder’s consent, and that is the first thing to settle rather than the last.
