What Happens in a Roof Survey? A Guide for East Yorkshire Property Owners

A professional roof survey is one of the most useful — and most under-used — tools available to East Yorkshire property owners. Whether you are buying a property, planning maintenance, or trying to decide between repair and replacement, a proper survey gives you the information to make an informed decision. This guide covers what a survey involves and what you should receive at the end of it.

What a Roof Survey Involves

A professional roof survey covers four areas: external inspection from ground level and if necessary from scaffold or access equipment; internal loft inspection; an assessment of all roof components — tiles, flashings, valleys, ridge, chimney, guttering and verge; and a written report with findings, recommendations and priority classification.

Our surveys in East Yorkshire are always written and always itemised by priority: P1 items that need attention immediately to prevent damage or address a safety concern; P2 items that need attention in the next 12 months; and P3 items to monitor. The report includes photographs of every significant finding and a cost indication for each recommended repair.

Roof Survey vs Home Buyers' Survey

The RICS Home Survey Standard sets out three survey levels, of which only Level 3 involves detailed inspection and analysis of the construction and its defects.

A standard RICS home buyers' report provides a very high-level assessment of the roof — typically a visual inspection from ground level only, with a condition rating. It is not a specialist roofing assessment. If a home buyers' report notes any concerns about the roof, a specialist roofing survey before exchange of contracts is strongly recommended.

A specialist roof survey will access the loft, inspect rafter and purlin condition, assess nail sickness probability based on housing era and visible tile condition, and provide a repair cost estimate. This is the information needed to negotiate on purchase price or budget for post-purchase maintenance.

When to Commission a Survey

Before buying a property: any East Yorkshire property built before 1980 with no evidence of a recent re-roof is a candidate for a specialist survey before exchange. Properties built in the 1960s–70s are approaching peak nail sickness risk and warrant particular attention.

Before planning major works: if you are planning a loft conversion, extension, or significant internal renovation, a roof survey before committing the budget to other works ensures you don't discover a re-roofing requirement halfway through a kitchen extension.

Annual or biennial maintenance: a brief written survey every 1–2 years gives you a documented maintenance log that supports insurance claims, and identifies items before they escalate.

We provide free written surveys for all standard residential re-roof and repair enquiries. Pre-purchase surveys with detailed repair costings are available at a fixed cost.

Drone Surveys: Where They Help and Where They Don't

Drone inspection has become common across East Yorkshire roofing in the last few years, and for good reason: it gives close-range imagery of ridge lines, chimney tops, valley runs and rear slopes that would otherwise need scaffold or a tower to see properly. On the tall three-storey Victorian terraces along Beverley Road and Spring Bank in Hull, a drone often produces a better picture in twenty minutes than a ladder inspection produces in an afternoon.

What a drone cannot do is assess anything by touch. Nail sickness is diagnosed partly by lifting a tile and seeing whether the fixing has any grip left; mortar condition is judged by pressing it; timber decay is found by probing. A survey that consists solely of aerial photography is an incomplete survey. Used properly, the drone supplements a physical inspection of the loft and accessible roof areas — it does not replace it.

Thermal Imaging and Moisture Detection

Thermal imaging cameras detect surface temperature differences, and wet material holds temperature differently from dry material. In practice this makes thermal imaging genuinely useful for two things on East Yorkshire roofs: locating the extent of moisture within a flat roof build-up, where water tracks laterally between the membrane and the deck and the visible stain bears little relation to the entry point; and identifying missing or displaced loft insulation from inside.

It is less useful on pitched tile roofs, where ventilation behind the covering evens out temperature differences. A contractor who offers thermal imaging on a flat roof investigation is applying it sensibly; one who presents a thermal image of a pitched tile roof as the basis for a re-roofing recommendation is overselling the technique.

Reading a Survey Report Critically

A useful report distinguishes clearly between what was observed and what is inferred. "Three slipped tiles on the rear slope, west end" is an observation. "Nail sickness likely to be widespread across this slope given the age and construction" is a reasoned inference. "Roof requires full replacement" is a recommendation. All three are legitimate, but they should be distinguishable from one another, and the recommendation should follow visibly from the evidence.

Be alert to reports that jump from a small number of observed defects straight to a large recommendation without the reasoning in between, particularly where the surveying contractor is also quoting for the work. This is not a reason to distrust contractor surveys in general — a working roofer usually reads a roof better than a generalist — but it is a reason to expect the logic to be shown.

Surveys for Insurance and Dilapidations

A dated, photographed survey report has value beyond deciding on repairs. For storm damage claims, a report from shortly after the event establishes the condition and supports the argument that the damage was weather-caused rather than the result of pre-existing disrepair — which is the ground on which insurers most often reduce or decline roofing claims.

For landlords and commercial tenants across Hull and Beverley, a condition survey at the start and end of a lease provides the evidence base for dilapidations discussions. In both cases the value lies in the report being contemporaneous and specific: dated photographs of identified locations, not general descriptions.

How Often to Survey

For an owner-occupied East Yorkshire house in reasonable condition, a professional survey every three to five years is proportionate, supplemented by your own ground-level and loft checks each spring and autumn. For property over 80 years old, for anything on the exposed coast at Hornsea or the Wolds edge, and for rental portfolios, every two to three years is more appropriate.

The exception is event-driven: after any significant storm, after any new internal damp appears, before buying, before committing to a loft conversion or extension, and before installing solar panels. In each of those cases the survey is not routine maintenance — it is decision-critical information, and it is worth having in writing.

Surveying Before Buying, Building or Installing

Three situations make a roof survey decision-critical rather than routine, and in each the cost is trivial against what it informs. Before purchase, it converts an unknown liability into a quantified figure that can be negotiated. Before a loft conversion or extension, it establishes whether the existing covering has enough life left to justify leaving it — because discovering otherwise after the room below is plastered is an expensive sequencing error.

Before solar panel installation it matters most of all, because panels fitted to a roof that needs recovering within a decade will have to be removed and refitted at your cost. We provide written surveys for all three situations across Beverley, Hull and the East Riding, and the report is yours to use however you choose — including to obtain competing quotations for any work it identifies.

What to Do With the Report Afterwards

A survey report has value beyond the immediate decision, provided it is kept. File it with your property documents alongside any guarantees and building regulations certificates, and keep the photographs with it. When the next survey is carried out, the comparison between the two tells you the rate at which any identified defect is progressing — which is often more useful than either report alone.

The report is also the natural basis for obtaining competing quotations, since it defines the scope precisely and lets several contractors price the same work. There is no obligation to use the surveying contractor for any resulting work, and a report that is only usable by the firm that produced it is not a report worth having. Ours are written to be used however you choose.
