Rooflight upstands & kerbs in Longsight

Replacing an old dome or a failed rooflight often means the kerb underneath has to change too: it may be rotten, too low for the new unit or the wrong size. We strip back what is needed, build a new upstand in Longsight to the new unit's dimensions, insulate it and dress the roof covering up to it. Where only part of the kerb has failed, we say so and price the smaller repair. The scope is set out in a written quote before work starts.

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.

Is your address covered?

Distance is rarely the deciding factor. A roof in Manchester, 2 miles from Longsight, gets the same survey, the same written quote and the same fitting process as one in M12, M13 and M14. What changes the price is the job itself: size of unit, roof type, access and lifting. Droylsden, around 3 miles out, is treated the same way.

Included in the work

  • Height set above the finished roof to the maker's stated minimum
  • Treated timber frame fixed down to the deck and joists
  • Fall built into the kerb where the rooflight needs one
  • Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.
  • 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

The fitters measure twice before cutting: the opening, the rooflight's kerb size and the finished roof level. The kerb is built, packed level or to the maker's fall, insulated and weathered into the roof covering. You are left with an upstand ready for the rooflight, and a note of the sizes it was built to.

Regulations for Longsight properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Getting a price from photos

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, M12 or nearby, confirms travel.

Common questions in Longsight

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.

Do I need planning permission for a rooflight in Longsight?

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.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.
