Straightforward like-for-like roof repairs are often different from changing the shape, height or visible character of a roof. The safest approach is to check the specific property and proposal rather than assume every roof job falls under the same rule.
Crawley has conservation areas
Crawley Borough Council identifies designated conservation areas and explains that some permitted development rights can be more restricted within them. That matters if work changes the external appearance rather than simply repairing a defect.
Listed buildings are a separate question
A listed building can require listed building consent for works that affect its special architectural or historic interest. Do not treat a listed roof as an ordinary like-for-like replacement without checking first.
Building regulations may still matter
Planning permission and building regulations are separate systems. Reroofing, structural changes and thermal upgrades can trigger building-regulation considerations even when planning permission is not required.
Check before ordering materials
If the property is listed, in a conservation area, or the work changes roof shape, height, materials or visible features, checking with the relevant authority before committing to the specification can prevent expensive rework.

Planning and building control answer different questions
Planning considers development and its effect on the building and surroundings. Building Regulations address matters such as structure, fire and energy performance. A roofing job can fall outside the need for a planning application while still requiring building-control consideration. Establish both routes before starting a substantial replacement or alteration.
Check the property as well as the proposal
Restrictions can relate to a listed building, conservation designation, an Article 4 direction or earlier planning conditions. A postcode alone does not settle the position. Check the exact address and the work proposed with the relevant authority. Rules applying to ordinary houses should not automatically be assumed to apply in the same way to flats or commercial premises.
Changes that deserve an early conversation
Changing roof shape or height, converting a flat roof to pitched, altering prominent materials or adding roof openings can raise different questions from repairing existing covering. A change in covering weight or structural support also needs assessment. Describe the proposal accurately and use drawings or photographs where needed, rather than asking only whether “roof repairs” need permission.
Insulation and replacement work
Larger roof renovation can bring thermal requirements into the project. The applicable guidance and any transition arrangements depend on the type and timing of the work. Check the requirements for the actual project with building control or the responsible designer before fixing insulation thickness and edge heights. A generic U-value copied from a website is not a substitute for that assessment.
Keep the decisions with the roof paperwork
Retain written advice, permissions and relevant completion documents alongside the quotation and product information. Clarify who is responsible for applications and inspections before the programme is agreed. This avoids assuming that a roofing quote automatically includes every approval or professional design task.
