Guide ranges for labour and materials, rooflight not included. 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 control fees, where a job needs them, are shown as their own line.
Where our fitters travel
Distance is rarely the deciding factor. A roof in Stockton-on-Tees, 3 miles from Thornaby-on-Tees, gets the same survey, the same written quote and the same fitting process as one in TS17, TS18 and TS16. What changes the price is the job itself: size of unit, roof type, access and lifting. Yarm, around 3 miles out, is treated the same way.
On the day, we cover
- Roof membrane turned up, bonded and finished at the kerb top
- Kerb sized from the maker's drawing, internal and external dimensions both checked
- Treated timber frame fixed down to the deck and joists
- Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
- Energy limit for site-built kerbs — We insulate upstands to meet the limit for site-built upstands, which is 0.35 W/m²K in England and Wales.
From arrival to clean-up
Building an upstand starts with the rooflight's own drawing: its kerb size, height above the finished roof and fall. The team sets the timber out to those figures, checks the diagonals, insulates the outer faces and dresses the membrane up and over. If the rooflight is going on the same day, it is fitted next; if not, the kerb is protected until it does.
Regulations for Thornaby-on-Tees properties
England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.
What to send for a quick quote
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, TS17 or nearby, confirms travel.
Common questions in Thornaby-on-Tees
Do you cover Thornaby-on-Tees?
Yes. Fitters travel to addresses in Thornaby-on-Tees and the surrounding districts, including TS17. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Do you offer trade rates for builders and roofers?
We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
Tell us your postcode, TS17 or close by, and what you want fitted. We will reply with the next steps and a quote.
