Loft conversion roof windows in St Andrews

Glass is heavy, and bigger units get heavy fast. Fitting a loft roof window in St Andrews means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across Fife.

Fitting across St Andrews and nearby

Jobs across KY16, DD6 and KY10 are part of our normal cover for St Andrews. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Dundee and Glenrothes are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Fit-only or supply and fit

There are two ways to do this. Supply and fit means we source a loft roof window that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What the job includes

  • Linings fitted, ready for the plasterboarder or decorator
  • Tiles or slates cut and refitted, with the roof left weathertight
  • Window positions set out on the slope to line up inside and out
  • Fitting stage and weather — We plan when the windows go in around the rest of the conversion.
  • Combination flashings — We order combination flashings where windows sit close together.

How a fitting day runs

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a loft roof window: one to two days, weather permitting.

Planning and building rules in Scotland

In Scotland a new rooflight needs a building warrant before work starts. A like-for-like replacement including the frame is exempt from a warrant but must meet current standards, so the glazing has to reach 1.6 W/m²K or better. For planning, rooflights on houses outside conservation areas can often go ahead under permitted development, but it is worth confirming with the planning authority.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in KY16, and we can price it.

Common questions in St Andrews

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

Can you fit the loft roof window I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the opening, the flashing kit and the roof pitch. The product warranty stays with the maker or seller, and our guarantee covers the fitting.

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
