Guide ranges for labour only — you supply the rooflight. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building warrant fees, where a job needs them, are shown as their own line.
Covering PA5 and neighbouring districts
Distance is rarely the deciding factor. A roof in Paisley, 3 miles from Johnstone, gets the same survey, the same written quote and the same fitting process as one in PA5, PA10 and PA9. What changes the price is the job itself: size of unit, roof type, access and lifting. Barrhead, around 5 miles out, is treated the same way.
Your rooflights or ours
A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.
What we do on the day
- Check of the delivered unit, glass, fixings pack and instructions before work starts
- Opening and upstand measured against the maker's drawing, timber to timber
- Internal reveal trimmed or lined, with the protective film removed at the end
- Access and lifting — We check how the unit gets from your drive to the roof.
- Upstand height above the roof — We measure how far the upstand stands above the finished roof surface, including any ballast or walkway.
Fitting your rooflight, step by step
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 rooflight: half a day to a day, weather permitting.
Do you need permission in Johnstone?
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.
Before you get in touch
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 PA5, and we can price it.
Common questions in Johnstone
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
What upstand height and roof pitch does rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
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.
