Take the roof off a building in the old part of Needham Market and you are looking at carpentry, not construction. Heavy principal rafters, purlins running between them, joints that were cut and pegged by hand, and several centuries of settlement since. Nothing in it is square. Nothing is level. No two rafter bays are the same width. That is the single fact that governs how a rooflight goes into the historic core of this town, and it has nothing to do with planning.
The town sits in the Gipping valley, 7.9 miles north-west of Ipswich as the crow flies, roughly twenty minutes up the A14 depending on how the Claydon junction is behaving. Period market town centre with a timber-framed core, then modern estates on the fringes. Two different jobs.
Why we measure the opening instead of ordering a size
On a modern roof you read the truss centres, pick the unit that fits between them, and order it. On a historic frame you cannot, because the bay you are aiming at is not one width. A bay that is nominally 550mm can measure 505mm down at the eaves and 570mm up at the purlin, tapering the whole way. Order a catalogue unit against the nominal figure and it either will not go in, or it goes in with a packed-out gap on one side that will show on the ceiling forever.
So we survey the actual opening. Every dimension, top and bottom, both sides, plus the out-of-square and the deviation across the plane. Then the unit is specified against those numbers. That is what the custom skylight design service exists for, and in the centre of Needham Market it is the normal route rather than the exception.
We work between the timbers, not through them
Historic structural timber does not get cut. A principal rafter or a purlin in an old frame is doing a structural job it has done for hundreds of years, it is not replaceable in kind, and on a listed building cutting it is a consent matter as well as a structural one. The rule is simple: the rooflight fits in the space that is already there.
That has consequences worth hearing before you get attached to a plan:
- The unit may end up smaller than you wanted, because the clear bay is what it is.
- Two smaller units in adjacent bays are often the answer instead of one large one. Different look, similar total glass area, no structural intervention.
- Where a bay is genuinely unusable, the daylight has to come from a different part of the roof, and we will say so at survey rather than after the scaffold is up.
Common rafters in a later infill can sometimes be trimmed with proper trimmers either side, which is standard practice on any pitched roof. Historic principal members are a different question and the answer is normally no.
Pantiles break, and we bring spares
Clay pantiles are the usual covering across this part of the Gipping valley, and they behave nothing like a plain tile. The profile is deep, so the flashing kit has to be the deep-profile version. Fit a plain-tile flashing under a pantile and the side laps stand off the covering, which is a leak with a date on it rather than a question of if.
Old clay is also brittle. Lifting tiles to form an opening breaks a proportion of them, and anyone who tells you otherwise has not done it. We plan for that. Matching replacements are on site before the covering is disturbed, sourced from reclaimed stock where the existing tiles will not match anything current, and the broken ones come off the roof rather than getting bedded back in with a crack in them. The pitched roof installation page goes through the flashing detail in full.
Nothing gets opened until the replacements are here. The roof is never left open waiting on a tile delivery, and never left open overnight.
Lime torching under old pantiles
One thing that surprises people about the historic pantile roofs here is what is on the underside. Many were finished with lime torching, a mortar fillet pointed between the battens on the inside to bed the tiles and keep wind-driven rain and snow out before roofing felt was ever used. Where it survives it is still doing a real job, and where it has crumbled it is often why an old roof feels draughty. Forming a rooflight opening in a torched roof means dealing with that fillet cleanly around the unit rather than knocking long lengths of it loose, and it is one more reason these roofs are opened slowly and by hand. It also tells us something useful at survey, because a torched roof with no modern underlay behind it wants the new opening detailed so the unit, not the old lime, is what keeps the weather out at that point. Where the torching has largely crumbled and the roof leans on the covering alone, we say so at survey, because it changes how the opening is weathered and it is the sort of thing worth knowing about the whole roof, not just the patch we are working on.
The other Needham Market
Away from the centre the picture changes completely. The fringe estates are trussed roofs: factory-made trusses at regular centres, usually 600mm, concrete interlocking tiles on top, felt and battens underneath, everything square and everything predictable. It is the easiest kind of roof we work on.
On those houses a standard roof window drops between trusses with no structural alteration at all, the flashing kit is a stock item, and the install is quick. VELUX window installation covers the bulk of that work, and where a loft conversion is involved the trusses do need designed alteration, which is a structural job with drawings rather than a saw and an opinion.
If you are upgrading rather than adding, energy efficient skylight installation is where the numbers live. Replacing units from the mid-2000s takes you from roughly 2.8 W/m²K to about 1.2, and a converted loft under a modern estate roof feels noticeably different in January.
An old roof has to breathe, and sealing it up causes damage
The instinct with an old timber-framed building is to make it warmer and tighter. On the roof that instinct has to be handled with care, because historic fabric was built to breathe. Lime mortars, permeable coverings and a naturally ventilated structure let moisture move through and dry out. Wrap a modern impermeable membrane and a sealed insulation layer around old oak without thinking it through and you can trap moisture against timber that has been dry for centuries, and rot follows quietly where you cannot see it. So when we form a rooflight opening in the historic core of Needham Market, the detailing around it respects how the rest of the roof handles moisture. That usually means breathable materials at the opening, ventilation paths kept open, and no cold pocket where warm interior air can condense against old timber. It is slower and more thoughtful than dropping a unit into a modern trussed roof, and it is the difference between a roof that stays sound and a hidden problem building up out of sight.
Getting to a roof on the high street
Access in the old centre is its own consideration. The historic buildings sit tight to a narrow high street with little room to the side and, for some, no rear access at all, so scaffold sometimes has to go up off the footway, which needs a licence from the highway authority and a bit of planning around the working day. Where there is no way round the back, materials and waste go through the building, and on a listed interior that means protecting historic floors and finishes as carefully as we protect a modern hallway. None of this stops the work. It is why the survey looks at the approach to the roof as closely as the roof itself, so the access is costed honestly rather than discovered on the first morning.
A short note on consent
The town centre is a conservation area and there are listed buildings within it. Listed building consent applies to works affecting a listed building, and in a conservation area the permitted development allowance for rooflights can be restricted. We check the status before quoting. It is a real consideration here, but it is not the hard part of a Needham Market job. The structure is.

We are along the A14 constantly. See Stowmarket, Great Blakenham and Claydon, or the full list at areas we cover.
Book a survey in Needham Market
Tell us which end of town you are in and what the roof is made of. If it is a timber frame, a photograph of the roof space from inside is worth more than any measurement you can give us over email. We survey, we quote once, and the figure holds unless the specification changes. Every install carries a 10-year workmanship guarantee. Request a fixed quote.
Can a rooflight go into a timber-framed roof where the rafter bays are irregular?
Usually yes, but the unit is specified to the surveyed opening rather than picked from a catalogue. We measure the actual clear width at several heights because an old bay typically tapers, and we work within the existing structure rather than cutting historic timber. Sometimes that means a smaller unit than you had in mind, or two smaller units in adjacent bays instead of one large one.
Will you break my pantiles taking them off?
Some of them, yes. Old clay pantiles are brittle and a proportion break on removal no matter how carefully they are lifted. We bring matching replacements to site before the covering is disturbed, using reclaimed stock where current products will not match, and cracked tiles are removed rather than reused. It is priced into the quote, not added afterwards.
Do I need a special flashing kit for pantiles?
Yes. Pantiles have a deep profile and need the flashing kit designed for that profile, not the plain-tile version. A plain-tile flashing sits proud of the covering at the side laps and lets water track underneath. It is one of the most common causes of a rooflight leaking on a Suffolk pantile roof.
Will fitting a rooflight in my timber-framed house cause damp or rot?
Not if it is detailed for the building it is going into. Old timber-framed roofs were built to breathe, and the risk comes from wrapping modern impermeable layers tightly around old oak, which can trap moisture that used to escape. We detail the opening with breathable materials, keep the existing ventilation paths open, and avoid creating a cold pocket where warm room air can condense against historic timber. Done that way, a rooflight sits happily in an old roof. Done the modern airtight way without thought, it can start a problem you will not see until it is advanced.
There is no access to the back of our high street property. Is that a problem?
It is a logistics question rather than a barrier. Where there is no side or rear access, scaffold may need to go up off the footway, which needs a highway licence, and materials and waste go through the building. On a listed interior we protect historic floors and finishes as carefully as we protect the roof. We look at the route to the roof at survey and cost the access openly, so the figure reflects the real job rather than a convenient assumption. On the tightest sites we will walk the access route with you before pricing so there are no surprises on the first morning.
