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.
Planning a new flat roof for a home in Alloa means making a handful of decisions about materials, layout, finish and timing. We help you work through them at a free survey, then confirm in writing what it will cost for the options you pick. Most projects of this type need 1–3 days for most roofs, and we cover every FK10 address as well as the rest of Stirling, Falkirk and Clackmannanshire.

Building in Alloa
Stirling's old town has historic stone buildings, with Victorian villas in the King's Park area and newer estates around the city. Falkirk and Grangemouth have industrial-era terraces and post-war housing, and Alloa and the Hillfoots villages in Clackmannanshire mix stone cottages, mill-era housing and harled council homes.
The Forth valley is prone to frost and low-lying flood risk, while the Ochil hills bring heavier rain to the Hillfoots.
In Alloa, as elsewhere in Stirling, Falkirk and Clackmannanshire, we take the building's age and construction into account before recommending anything, because both can change what is involved in a new flat roof.
Permissions for a new flat roof in Alloa
The notes below cover Scotland, which is where Alloa sits. Rules change and every property is different, so we speak to the council before pricing your job.
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?
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for a new flat roof so the price reflects your home.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Plan and prepare
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for a new flat roof are in place before the first day on site.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

Flat roofs in Alloa: questions
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 you repair my flat roof instead of replacing it?
A flat roof can often be repaired if the damage is limited to a small split, a failed joint or a loose upstand and the rest of the covering is sound. If the deck is soft, the covering is blistered or cracked across the roof, or leaks keep returning, replacement is usually better value. We assess the whole roof and give you an honest recommendation.
How long does a flat roof replacement take?
Replacing a typical extension or garage flat roof usually takes one to three days. Stripping and any deck repairs come first, then insulation where agreed, the new membrane and the trims and outlets. GRP needs dry weather and time to cure, and we plan around the forecast. Larger roofs or roofs with many rooflights take longer. We confirm timing with your quote.
Which postcodes in Alloa do you cover?
We cover FK10, along with the rest of Stirling, Falkirk and Clackmannanshire. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Do I need planning permission in Alloa?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Alloa is in Scotland, so Scotland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
