Roof Inspection

Roof Inspection near you

A roof inspection is a piece of reporting, not a piece of building work, and the reason people buy one is almost always a decision: whether to buy a house, whether to accept a roofer's diagnosis, whether to claim, or whether a roof that has been patched four times is finished. What you are paying for is somebody competent looking at the covering, the flashings, the rainwater goods and the roof space, and writing down what they saw and what it means.

In Britain two quite different professions sell this. Chartered surveyors work to the RICS Home Survey Standard, which sets the framework and three levels of service; RICS made the current home survey reports mandatory for its members from 1 September 2021, and a member needs a Home Surveys Licence to produce reports at any level. Roofing contractors also offer inspections, which are usually more detailed about the covering and less independent, because the same firm often hopes to do the work.

The third route is a drone, which has changed what is possible on a steep or a high roof and brought a second rulebook with it. Flying a camera drone over a house is regulated by the Civil Aviation Authority, and the distances that apply are not obvious from the ground.

The RICS survey levels, and what a roofer's inspection is instead

The RICS Home Survey Standard exists to set a clear framework of minimum expectations for residential property survey services, and it describes three levels. Level 1 is the most basic, an initial assessment of the property's condition. Level 2 is the middle option and is offered either as a survey on its own or as a combined survey and valuation. Level 3 is the most detailed inspection and analysis. The new reports became mandatory for RICS members from 1 September 2021, after a transition period that ran from 1 March to 31 August 2021, and members require a Home Surveys Licence to produce them.

For a roof specifically, the level decides how much you learn. A lower-level survey is looking at a whole house and will describe the roof in general terms from what can be seen; a Level 3 inspection goes further into condition and into why something has happened. What no residential survey does by default is walk the covering, so if you want the roof itself examined closely you are usually commissioning a separate piece of work.

A roofing contractor's inspection is a different product. It will normally be more specific about slates, flashings, valleys and the roof space, and may include photographs from a ladder, a tower or a drone. Its weakness is independence: a free inspection offered by a firm that wants the contract is a sales visit with a useful technical content, and it is worth treating it as such rather than as a second opinion.

How a thorough roof inspection is actually carried out

  • It starts inside, in the roof space, with a torch: daylight through the covering, staining on rafters and purlins, the condition of the underlay, damp at the wallplate and rafter feet, and whether the insulation is blocking the eaves.
  • It moves to the ground with binoculars, which find slipped units, displaced ridges, failed flashings and blocked hoppers without anyone leaving the lawn.
  • Close inspection of the covering then needs equipment chosen under the work at height rules, which other guides on this site set out; nobody should be improvising with a ladder on a wet slope.
  • A drone survey covers the parts nobody can safely reach, and produces a photographic record that can be compared year to year.
  • Rainwater goods are checked while it is raining if possible, because a gutter that is falling the wrong way only shows when there is water in it.
  • The chimney, the abutments and the valleys get disproportionate attention, because that is where most British roofs actually leak.
  • The output should be a written report with dated photographs, a clear statement of what was not inspected and why, and a separation of what is urgent from what is merely noted.

Drone roof surveys and the CAA rules that govern them

A drone carrying a camera is an aircraft in law, and the Civil Aviation Authority's Open category rules apply whether the flight is a hobby or a paid survey. Registration comes first: a Flyer ID is required if the aircraft weighs 100 grams or more, and an Operator ID is required if it weighs 100 grams or more and has a camera. Flying without them is against the law and can bring a fine or imprisonment.

The Open category is divided into subcategories by how close to people the aircraft may go. In A1, over people, you may fly closer to people than 50 metres horizontally and over people who are not involved, and you may operate in residential, recreational, commercial or industrial areas. In A3, far from people, you must not fly closer to uninvolved people than 50 metres horizontally, must not fly closer to residential, recreational, commercial or industrial areas than 150 metres horizontally, and must not fly closer to individual buildings than 50 metres. Both limit the flight to 120 metres, or 400 feet, in height. A2 sits between them and requires a competency certificate obtained by examination.

Read those numbers against a roof survey and the point becomes obvious: an A3 aircraft cannot lawfully be used to photograph a house in a street, because a house in a street is a residential area and the aircraft would be within 50 metres of an individual building. That is why a professional drone roof survey is flown either with an aircraft small and light enough for A1, or under an A2 certificate, or under an operational authorisation in the Specific category. Ask which, and ask to see it, before booking.

When an inspection is worth paying for

  • Before exchanging on a period house, particularly one with a slate roof, parapets, valleys or a rear addition.
  • After a named storm, where an independent record of the damage will be the basis of an insurance claim.
  • When the same leak has been repaired twice by different firms and nobody has explained why it keeps coming back.
  • Before committing to a re-roof, so that you are comparing quotations against an independent description of the problem rather than against each other.
  • When you have inherited or bought a property with no maintenance history and want a baseline to work from.
  • Where a neighbour's work, a party wall or a shared parapet gutter is involved and you want the condition recorded before anything starts.
  • When solar panels, a loft conversion or additional insulation is planned, since all three change what the roof and the roof void have to cope with.

What the report should say, and what it can never say

A useful report is explicit about its own limits. It should state what was inspected, from where, and with what equipment; what was not inspected and why, which on most roofs includes anything under the covering and anything that could not be safely reached; the date, the weather, and whether the roof was wet. Photographs should be dated and located, not a generic gallery. Recommendations should be separated by urgency, and the report should distinguish between what the inspector saw and what he infers from it.

What no inspection can do is guarantee that the roof will not leak. A visual survey finds visible defects on the day; it does not open up the construction, and a great deal of what goes wrong on a British roof is concealed by the covering. That is why a report that reads as reassurance rather than description is worth less than one that lists the uncertainties.

If the inspection is by an RICS member, ask which survey level you are buying and read the description of that level before you agree the fee, because the difference between levels is the difference between a condition summary and an analysis. If it is by a contractor, ask straight out whether the inspection is free because the firm wants the work, and get the fee and the independence position settled in advance.

What drives a roof inspection quote, and how LokalMatch fits in

Inspections are priced on access, depth and liability. What moves the figure is how the roof will be reached and whether a tower, a scaffold or a drone is involved, whether the roof space can be entered and how easily, the size and complexity of the building, the level of survey being bought and therefore how much analysis rather than description you get, how quickly the report is needed, and whether the inspector is carrying professional indemnity for advice you will act on. An independent report costs more than a free visit from a firm hoping to quote, and that difference is the product.

LokalMatch is the introduction, not the surveyor. Describe the building and what you want to know once, with your postcode, and surveyors and roofing firms working in your area get in touch with you directly. There is no charge to homeowners for posting a request; the businesses pay for the requests they receive. LokalMatch does not inspect roofs, does not set prices and does not vet, rank or recommend anyone who replies, so asking what qualifications, what survey level and what insurance stand behind the report is a question only you can put.

Roof Inspection: frequently asked questions

Does a normal house survey tell me about the roof?

Up to a point, and the point depends on the level you bought. The RICS Home Survey Standard describes three levels: Level 1 is a basic initial assessment of the property's condition, Level 2 is the mid-tier option available as a survey or as a combined survey and valuation, and Level 3 is the most detailed inspection and analysis. RICS made these reports mandatory for its members from 1 September 2021. None of them involves walking the covering, so if the roof is your specific concern, commission a separate inspection.

Is a drone roof survey legal over my house?

It can be, but not with every aircraft or every operator. The CAA requires a Flyer ID for any aircraft weighing 100 grams or more and an Operator ID where it weighs 100 grams or more and has a camera. In the A3 subcategory an operator must not fly within 150 metres of a residential, recreational, commercial or industrial area, must stay 50 metres from uninvolved people and must not fly closer than 50 metres to individual buildings, which rules out a normal street. A legitimate drone survey of a house is therefore flown under A1 with a suitably light aircraft, under an A2 certificate, or under an authorisation in the Specific category. Ask which.

Should I use the roofer who is quoting to inspect the roof?

Their inspection will usually be the most technically detailed, and it is also the least independent, because the firm wants the contract. Both things are true at once. A reasonable approach is to take a contractor's inspection for the detail and an independent report for the decision, particularly where a re-roof rather than a repair is on the table. Whichever you choose, get the report in writing with dated photographs rather than a verbal verdict at the door.

How often should a roof be inspected?

There is no legal interval for a house, so the sensible rule is event-driven rather than calendar-driven: after any storm that caused damage locally, after work has been done on or near the roof, before and after a winter on a building you know is marginal, and whenever the roof space shows something new. A dated photographic baseline is the most useful thing an inspection produces, because next year's inspection can be compared with it rather than judged from scratch.

The inspection found problems the seller's survey missed. What now?

That is common, and it usually reflects the level of service rather than negligence. A basic assessment of a whole property and a dedicated roof inspection are different products with different scopes, and a good report of either kind says what it did not inspect and why. Read both reports side by side and look at their stated limitations first; if the difference cannot be explained that way, take it up with the firm that produced the earlier report through its complaints procedure.

Can the inspector go into the loft?

Usually yes, and it is the most informative part of the visit. From inside you can see daylight through the covering, staining on rafters and purlins, the state of the underlay, damp at the wallplate and rafter feet, and whether insulation has been pushed into the eaves and blocked the ventilation path. What an inspector will not do is start lifting insulation, walking between joists in an unboarded loft or moving stored belongings, so clearing the hatch and the immediate area before the visit gets you more for your money.

What affects the cost of roof inspection

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Roof size and the number of layers to remove
  • Roofing material
  • Slope and how steep the roof is to work on
  • Access to the roof and the site
  • Condition of the decking underneath
  • Flashing, vents, skylights and chimneys to work around
  • Amount of repair work compared with a full replacement

How to compare roofers before you hire

  • Ask for a written quote that lists the materials, the scope of work and what happens if damaged decking is found once the old roof is off.
  • Look for a roofer who inspects the roof in person, including the attic if possible, before giving you a price.
  • Check that they carry liability insurance and workers' compensation coverage, since roof work is high-risk.
  • Compare quotes on the same scope: tear-off or overlay, underlayment, flashing, vents and cleanup.
  • Ask to see recent roofs they've done that are similar to yours in material and slope.

Questions to ask roofers before you hire

  • Will you remove the old roofing or install over it, and why?
  • How will you handle damaged decking or other surprises once the roof is open?
  • Who will pull the permit if one is needed?
  • Can you show me proof of liability insurance and workers' compensation coverage?
  • What warranty do you offer on your workmanship, and how long does it last?
  • How will you protect my yard, gutters and siding, and how will you clean up nails and debris?
  • Will your own crew do the work, or will you use subcontractors?

When to call a pro for roof inspection

  • Water stains on ceilings or in the attic after rain or snowmelt
  • Missing, curled or cracked shingles, or granules collecting in the gutters
  • Sagging areas on the roof, which should be looked at by a professional right away
  • Ice dams that keep forming along the edge of the roof

Roof inspection permits and local rules

Some roof inspection work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
