S&S Roofing & Building Limited works right across Portsmouth's dense terraced streets and shared roofs, a short drive over from our Havant base. Free inspection, photographs of the actual roof, and a fixed written price before anything is touched.
Free inspection and free quote in Portsmouth, no obligation — if a shared roof only needs a section repairing, we will say so rather than quoting for more.
Local coverage
Portsmouth packs more roof per square mile than almost anywhere else we work, and the Solent decides how those roofs age. We are close enough, over from Havant, to be on site quickly and to already know how the terraces here behave.

S&S Roofing & Building Limited works regularly across Portsmouth, from the bay-fronted Victorian terraces of Southsea and the tight Fratton streets around Milton Road, through North End and Copnor's mix of terraces and inter-war semis, into the rebuilt post-war housing of Portsea and Landport near the dockyard, and out to the flats and converted HMOs that now make up a large share of the city's housing stock. Each of those areas has a different roof problem waiting on it, and we price for the one in front of us.
Being an island city, Portsmouth gets wind exposure that inland Hampshire towns simply do not see. Gusts come straight off the Solent and Spithead with nothing to slow them until they hit a roof, and that means ridge tiles, hip tiles and loose flashings fail here faster than the same details would thirty miles north. Salt carried on that wind settles on every exposed roof surface in the city, working into mortar joints, corroding cheap fixings and shortening the life of unprotected steel and aluminium guttering. A gutter system that lasts twenty-five years in Petersfield can be doing well to see fifteen a few streets back from Southsea seafront.
The housing itself adds complications you do not get in newer towns. Southsea and Fratton terraces share party walls and often share valley gutters between adjoining roofs, which means a blockage or a split membrane on next door's slope can send water into your loft even though your own tiles are sound — diagnosing that properly matters more here than almost anywhere else we work. Bay windows are everywhere in these streets, each one topped with a small lead flat roof that takes constant abuse from rain running off the main slope above it, and chimney stacks stand tall and exposed on terrace after terrace, doing double duty as party-wall stacks shared between two households.
Portsea and Landport's post-war rebuild housing behaves differently again — flatter roof pitches, less generous eaves detailing, and in many streets the 1960s and 1970s flat-roofed rear extensions that were added to almost every property of that era. Those extensions were built to a budget and a standard that has not aged well; decades-old felt has usually gone brittle, cracked at the laps, or is sitting with standing water because the fall was never quite right to begin with. Flats and converted HMOs across the city bring their own access and liability questions, particularly where a landlord needs documented evidence of roof condition for insurance or before a tenancy change, which is exactly what our photographic report after every inspection is built to provide.
Regular same-day or next-day inspections, with genuine 24/7 attendance for leaks, storm damage and emergencies anywhere on the island, from Southsea to Portsea.
Victorian bay-front terraces, Edwardian and inter-war semis in North End and Copnor, post-war rebuild housing in Portsea and Landport, converted flats and HMOs, and 1960s-70s flat-roofed extensions.
Shared valley gutter leaks between adjoining terraces, lead bay-roof failures, chimney stack repointing on party walls, and ageing felt flat roofs on rear extensions.
Narrow streets, on-street parking and shared rear access are the norm in Southsea and Fratton. Where scaffold cannot go up easily, or where a shared roof is unsafe to walk, we survey it by drone from £250.

Drone surveys in PortsmouthWhy Portsmouth calls us
Terraced and shared roofs raise questions a detached house never does — whose responsibility is that valley, is the leak really yours, what does the landlord need in writing. We answer those properly rather than guessing.
Portsmouth is a short journey from our Havant base, so inspections and emergency call-outs do not depend on a roofer travelling across the county first.
Tommy-Davey Stevens and Jordan Jay Stevens run the business themselves across Hampshire and West Sussex, with a team of six. An owner is on the phone from your first call.
We check adjoining slopes and shared valleys before pricing, so a Portsmouth homeowner is not quoted for their own roof when the fault sits next door.
Photographic reports and drone survey imagery give landlords, letting agents and buyers documented proof of roof condition, not a verbal opinion.
Materials and labour itemised separately, in writing, before work starts. The price you accept is the price you pay.
£1,000,000 public liability insurance, plus a workmanship guarantee confirmed in writing with your quote — cover varies by job type.
“From start to finish, the service provided was excellent. It is clear that they take great pride in their work and genuinely care about making sure their customers are happy with the finished result. There was no pressure, and I felt confident that I was receiving genuine advice and a fair price. They were also respectful of the property and left everything clean and tidy once the work was finished.”
Local conditions
An island city with dense Victorian terracing, salt air off the Solent and a large stock of post-war and flat-roofed housing produces a narrow, predictable set of failures — we see the same handful of causes on street after street.
Where two Southsea or Fratton terraces meet, the valley gutter between them often serves both properties. Debris or a split membrane on one side can overflow straight into the neighbouring loft, so a leak inside your house is not always coming from your own roof.
With open water on more than one side of the city, Portsmouth takes gusts with nothing to break them. Ridge and hip tiles bedded in old mortar lift first, and once one tile has gone the exposed batten and felt beneath it are next.
Constant salt-laden air corrodes nails, screws and cheap guttering brackets far faster here than a few miles inland, which is why a Portsmouth gutter run can fail while it still looks structurally sound from the ground.
Almost every Southsea and Fratton terrace has a bay window with a small lead flat top beneath the main roof. These sit directly under run-off from the slope above, and once the lead has split or lifted at the upstand, water tracks straight into the bay ceiling below.
Chimney stacks shared between two terraced properties take weather from every direction and often carry flashing maintained inconsistently by whichever owner last touched it, which is why chimney leaks are one of the most common call-outs on Portsmouth terraces.
Portsea, Landport and much of the wider city carry rear extensions built with mineral felt decades ago. That felt has generally hardened and cracked at the laps by now, and many were laid with too shallow a fall, so standing water is a routine finding on inspection.
In a city this densely built, the honest diagnosis often takes longer than the eventual repair. A damp patch on a Fratton bedroom ceiling could be a shared valley gutter blocked two doors along, a split lead bay top directly below it, a slipped ridge tile after a Solent gale, or condensation from a poorly ventilated loft in a converted flat — and each of those has a different fix, a different cost and a different party responsible for paying for it. Treating every leak as 'your roof, full re-tile' is how Portsmouth homeowners end up arguing with a neighbour or a letting agent over a bill that should never have been theirs.
That is why we inspect free of charge and hand over a photographic report before any pricing conversation happens. If the fault sits on a shared slope, we will say so and explain what that means for who pays. If a Southsea terrace genuinely needs a full strip and re-tile after years of storm damage, you will see the evidence for that too, in writing, with materials and labour itemised separately so you can check it against anyone else's quote.
Our process
The phone is answered 24 hours a day by one of the owners. Tell us the address in Portsmouth and what you are seeing, and we will tell you straight away whether it is urgent.
We come out to your Portsmouth property and inspect the roof properly — including a drone survey from £250 where access is awkward or the pitch is unsafe to walk.
You get photographs of what is actually up there, so you are looking at the same evidence we are rather than taking a roofer's word for it.
A fixed price in writing with the materials and labour set out separately, plus the workmanship guarantee for that job type. The price you accept is the price you pay.
We turn up on the date we gave you, finish inside the timeframe, and leave your Portsmouth property as tidy as we found it. Cash or bank transfer on completion.
Straight answers
Anything not covered here, call 07926 240983. You will speak to an owner, not a salesperson, at any hour of the day.
