Guide ranges for supply & fit. 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.
Areas around Weymouth we cover
Distance is rarely the deciding factor. A roof in Dorchester, 7 miles from Weymouth, gets the same survey, the same written quote and the same fitting process as one in DT4, DT3 and DT5. What changes the price is the job itself: size of unit, roof type, access and lifting. Poole, around 22 miles out, is treated the same way.
Buying your own, or letting us supply
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a sun tunnel on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
On the day, we cover
- Ceiling opening cut neatly and the diffuser fitted
- Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
- Dome fixed and sealed on top of the flashing
- Flat or pitched roof kit — We confirm the roof type and covering before ordering the kit.
- Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
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 sun tunnel: half a day to a day, weather permitting.
Regulations for Weymouth properties
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
What to send for a quick quote
Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around DT4. That is enough for a first price.
Common questions in Weymouth
Do you cover Weymouth?
Yes. Fitters travel to addresses in Weymouth and the surrounding districts, including DT4. 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.
Do you make good inside after fitting?
Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.
Do I need planning permission for a rooflight in Weymouth?
Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
