A flat roof replacement strips the old covering from a low-pitched roof and lays a new waterproof system, usually EPDM rubber, GRP fibreglass or torch-on felt, over a sound deck with correct falls, upstands, trims and outlets so rainwater drains away.
Cost is usually the first question about a new flat roof, so here is the guide for Scotland: £1,900–£4,300 including VAT. We cover the whole of Aberdeen and Aberdeenshire, with Aberdeen, Peterhead, Nigg and Inverurie among the main centres. Because each UK nation sets its own rules, we check the requirements in Scotland for your property, then put a firm price on paper following a free survey.

Homes in Aberdeen and Aberdeenshire
Aberdeen is built largely of grey granite, from tenements and terraces to granite villas in the West End, with post-war council housing and newer estates on the outskirts. Across Aberdeenshire, harled stone cottages, fishing-town terraces in Peterhead and Fraserburgh, and modern developments in commuter towns such as Westhill and Ellon are common.
Granite walls need repointing with a mortar matched to the stone, and slate roofs often want attention after hard winters. Harled cottages need breathable finishes, while newer estates commonly add extensions, garage conversions and driveways.
Cold North Sea winds, coastal haar and hard winter frosts are routine, so roofs, harling and exposed fixings need a robust specification.
Planning and building rules in Aberdeen and Aberdeenshire
Planning law differs across the UK. For a home in Aberdeen and Aberdeenshire, it is the Scotland rules below that count, and we check them with the council ahead of any quote.
In Scotland, like-for-like re-roofing does not usually need planning permission, except on listed buildings or in conservation areas.
Like-for-like re-covering does not usually need a building warrant, but structural changes or new roof windows can. Bats are protected across the UK; if they roost under roof tiles, soffits or fascias, work stops and a licensed ecologist advises before it restarts.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
Free site survey
We begin by looking at the job in person. During the free survey we discuss options, materials and budget for a new flat roof, and photograph or measure anything the quote needs to reflect.
Quote in writing
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Getting ready
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.

Frequently asked questions
How long does a flat roof last?
A well-installed EPDM or GRP flat roof can last 25 years or more, while torch-on felt systems typically last around 15–25 years, depending on quality and exposure. Lifespan depends on correct falls, good detailing at edges and upstands, and keeping outlets clear. Foot traffic, ponding and poor ventilation shorten it. Annual checks help catch small problems early.
Should I insulate my flat roof when it is replaced?
Replacing a flat roof is the most cost-effective time to add insulation, because the covering is already off. A warm roof, with insulation laid above the deck, keeps the structure warm and reduces condensation risk. Building regulations may require insulation when a large part of the roof is renewed. It raises the roof height slightly, which affects trims and upstands.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from a new flat roof, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
Why does water sit on my flat roof?
Ponding water on a flat roof is usually caused by inadequate falls, sagging joists, a deck that has dipped or blocked outlets. Small puddles that dry within a day or two are not always a problem, but standing water speeds up wear and finds any weakness. A new roof can be laid on firring strips or tapered insulation to create proper falls. We check falls during the survey.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
