A measure survey of a roof for a quote. Record the roof type, age and access, and whether there are fragile surfaces or materials that could contain asbestos. Add each slope or flat area with its covering, eaves length, top edge length and rafter length, and the form works out each area and the total. Then record ridges, hips, valleys, verges, flashings, gutters and downpipes, chimneys and rooflights, and the work recommended. Every question is listed below, and you can fill the live form in on this page.

Measure each slope's eaves length, its top edge or ridge length, and its rafter length up the slope from eaves to ridge. The slope area is the average of the eaves and top lengths times the rafter length: eaves times rafter for a rectangular slope, half that for a triangular hip end. Add the slopes for the total, then measure the ridges, hips, valleys, verges, flashings, gutters and downpipes, and note the covering, pitch, condition, access and safety issues such as fragile surfaces or asbestos.
Last updated . Facts checked by the SiteSurvey team on 17 October 2026 against HSE: roof work, HSE: why asbestos is dangerous and where it can be found and HSE: locations of asbestos and the materials it was used in.
Measure each slope or flat area as its own row. The form works out each slope's area and the total roof area as you go, and each slope keeps its own photos and defects.
Enter the eaves length, the length along the top edge and the rafter length up the slope, and the form works out that slope's area. The total roof area adds every slope together, ready for the quote.
How calculated fields work →
Where you cannot get a tape to it, estimate the eaves length, or the length along the top edge, from a photo of the elevation with a door or a person in the same plane. It is an estimate, so check it on the scaffold before ordering. It works on web forms in any phone browser today, and the app version is on its way.
How measuring from a photo works →
Each slope takes its own photos and defects, so slipped slates on the rear slope stay with the rear slope in the report.
A fictional Victorian terrace measured for a re-roof quote: front and rear slate slopes and a tiled outrigger, about 68.5 m² in total, with ridge, verge, gutter and flashing lengths and the scope of work.

A roof survey and measure for quoting: each slope with its covering, eaves and rafter lengths, area and pitch, ridges, hips, valleys and rainwater goods, access, fragile surfaces and asbestos. 4 sections and 45 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.
This is a starting point, not a fixed form. Once it is in your SiteSurvey account you can reword any question, add or remove questions, sections and answer options, and add your own logo, so it fits the way your team works and the jobs you do.
Add this form to a project in SiteSurvey and it fills in what the project already knows, so nobody on site retypes it and every form on the job uses the same names. Anything filled in can still be changed.
Optional. Film a guided walk-through on the SiteSurvey app.
Record estimated current conditions and add what you observe on site.

Yes. Enter the eaves, top edge and rafter lengths for each slope and the form shows the slope area in square metres, then adds all the slopes for the total roof area. It works for rectangular slopes, tapering slopes and triangular hip ends.
The rafter length is the true sloping length, so it gives the actual area to cover. A plan measurement would need a pitch factor.
HSE says the main causes of death and injury in roof work are falls from roof edges or openings and through fragile roofs and rooflights, and that all roofs should be treated as fragile until a competent person has confirmed they are not. The form asks about fragile surfaces and shows that warning.
HSE says asbestos can be present in any building built or refurbished before 2000, including asbestos cement roof sheets and tiles, soffits and undercloaks. The form asks about suspect materials and reminds you to have them checked before quoting work that disturbs them.
Yes. The optional Walk Cam guides you to film each elevation from the ground and close-ups of defects, so the estimator sees what you saw.
