Roof Potential
We look at your roof from the aerial data and your elevation photos: tile condition, ridge line, chimneys, valleys, dormers, gutters and any obvious failure points. Then we tell you what's realistic. Re-roof in slate or tile, remove a redundant chimney, add a rooflight, replace the fascias, insulate at rafter level. With the planning verdicts and the cost bands for each direction.
- I think the roof needs doing
- I'm planning to re-roof before I extend
- I want a chimney removed and a rooflight added

Visualised on your property
Re-roof, restore the chimney, add a rooflight; what your roof needs and what it could become.
There were three slates in the front garden after the last storm. The roofer who came round muttered about "the whole thing needing doing" and left a number on a piece of paper. You don't know if your roof has another decade in it, whether the chimney can come down, or whether a rooflight in the rear bedroom needs planning. The Roof Potential report reads your roof from precision aerial data and your elevation photos and tells you, in plain English, the priority list and the cost ladder.
What you actually get
Six concrete things inside the report.
Not a generic guide. These are the specific deliverables we ship for your address, every single time.
Roof condition assessment
A read of the condition we can see: ridge tiles, slate or tile coursing, valley flashings, lead work, chimneys and fascias. With a plain-English priority list.
Three re-roof options visualised
Like-for-like, sympathetic upgrade and full restoration. Same roof line, same chimneys (if kept), each rendered onto your elevation.
Rooflight and dormer feasibility
What you can put in under Permitted Development on your house type, with Conservation Area and Article 4 flags. Includes flush conservation-style rooflights for sensitive elevations.
Cost ladder for each direction
Slate vs concrete vs clay tile, chimney removal vs restoration, gutters and fascias, scaffolding. Broken down so you can argue with a quote.
Insulation and EPC uplift
Whether to insulate at ceiling level, at rafter level (warm roof), or both. With the EPC band move and bill savings each option tends to deliver.
Built from this data
Grounded in the actual evidence of your property.
Every recommendation in the report ties back to one of these data streams. No generic Wikipedia summaries; no postcode averages.
Aerial survey of your exact roof
Pitch, area, ridge length, chimney count and any obvious dormer or rooflight openings. Modelled from precision aerial data, not estimated from a postcode.
Your elevation photos, read like a roofer
Slate slip, lead failure, ridge displacement and pointing condition; the cues that decide whether a refresh will hold or a full re-roof is overdue.
Planning constraints on your plot
Conservation Area, Article 4, listed status. The factors that decide whether a chimney can come down or a velux can go in without an application.
What it looks like
A glimpse of the report itself.
The full report lands as a single scrollable page. Visualisations sit alongside the costs, planning verdicts and value uplift, so you can argue with it (or with your partner) in one place.
Visualisation for this property
Freshly relaid natural slate roof on a Victorian semi with restored brick chimney and a slim rooflight set flush into the slate.
The verdict (one sentence)
Re-roof, restore the chimney, add a rooflight; what your roof needs and what it could become.
Cost ladder
Likely value uplift
Typically +£8k to +£25k; bigger story is on price held
Cost & value
What it costs. What it adds.
Honest bands tuned to UK pricing in the last 12 months, plus a value uplift range for homes in your bracket.
Replace slipped tiles, re-bed ridge tiles, repoint flashings, paint or replace fascias and soffits, clean and re-pin the chimney. Same roof, fixed.
Strip and re-lay in matching slate or tile, new battens and membrane, new lead, new ridge, scaffolding included.
Full re-roof, chimney restoration or removal, flush conservation rooflights, warm-roof insulation, new gutters and downpipes.
Roof condition is a major surveyor flag in sales. Resolving it before the survey often saves more in negotiation than the value uplift shows on paper.
The fine print, up front
What this report does not cover.
A clear list of what we leave out, so you never feel short-changed when you open it.
- Structural truss work where the roof itself has spread (separate engineer)
- Asbestos removal in soffits or insulation (specialist trade)
- Party-wall awards where a chimney removal affects a shared stack (your builder organises)
If we can't make this report outstanding for your address, you don't pay.
If we can't find the photos, planning history or constraints we need to make this specific report genuinely useful for your house, we refund the full price before generating a single word. Same goes if you read it and it just doesn't deliver.
