A roof replacement, or re-roof, strips the old tiles or slates, battens and felt from a pitched roof and replaces them with a new breathable membrane, battens and covering, repairing timbers and renewing ridges, valleys and flashings at the same time.
Homeowners in Johnstone usually consider a new roof for one of a few reasons: something has worn out, the house no longer suits the way they live, or they are getting it ready to sell. We visit, agree a specification and put a fixed price in writing. Most jobs like this take 1–2 weeks on site, plus scaffolding time, and we work across Renfrewshire and Inverclyde, including Paisley, Barrhead and Erskine.

- Chimneys, leadwork and roof windows to rework
- Scaffolding, access and the height of the house
Scope of the work
- Scaffolding with edge protection, erected and removed
- Stripping old tiles or slates, battens and felt in stages
- Breathable membrane and new treated battens
- New tiles or slates, or sound originals refitted where suitable

What are homes like around Johnstone?
Paisley has sandstone tenements and terraces from its textile era, Greenock and Port Glasgow have tenements and housing climbing the hills above the Clyde, and Gourock and Kilmacolm have Victorian villas. Post-war estates and newer private housing surround the towns, and roughcast is a common finish.
Roughcast and tenement buildings commonly need re-rendering, window replacement and roof work. Villas suit kitchen extensions and landscaping, and semis often take loft conversions and driveways.
These patterns matter for a new roof: older walls, roofs and floors in Johnstone can need different materials or extra preparation compared with newer homes.
Planning and building rules in Johnstone
Which rules apply depends on where you live. For Johnstone, the answer is Scotland, and the points below reflect that; we verify them with the council before quoting.
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.
What happens after you get in touch?
Free site survey
First, someone visits your home in Johnstone to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Written quote
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for a new roof.
Dates and permissions
Before anyone starts, we confirm the programme in writing, check whether consents are required and arrange deliveries. If a skip or scaffolding on the road needs a permit, we apply for it.
Build and hand over
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.
How we work
Common questions
What happens if it rains during the work?
We strip the roof in sections and only remove as much covering as we can replace or protect the same day. New breathable membrane goes on straight after stripping, which keeps most rain out, and we sheet exposed areas at the end of each day and before forecast showers. If heavy rain or high winds are forecast, we pause work. The house is never left open.
Can my old tiles or slates be reused?
Old tiles or slates can sometimes be reused if they are sound, which can help keep the look of a period house. Many older concrete tiles and some slates are porous, cracked or have failing fixing nibs, so they would not last. Reclaimed slates or tiles can make up shortfalls. We check a sample during the survey and explain the cost difference.
Do you cover Paisley, Barrhead and Erskine?
Yes. As well as Johnstone, we cover Paisley, Barrhead and Erskine and the rest of Renfrewshire and Inverclyde. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
Will my loft insulation and ventilation be improved?
Re-roofing is a good time to improve loft ventilation and insulation. A breathable membrane and eaves or ridge vents keep air moving and reduce condensation in the loft. Building regulations may require insulation upgrades when a large part of the roof is renewed. We check your current insulation and ventilation and include any required improvements in the quote.
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 roof, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
