New Roofs & Re-Roofing in Sussex
When a roof has reached the point where repairs keep returning, a new covering can protect the home and renew its appearance. SENTRY handles planned re-roofing across Sussex, including the roof edges and weatherproof details that complete the job.

New roofs for Sussex properties
A few repairs do not mean a whole roof needs replacing. If leaks return across several slopes or the coverings, fixings or underlay have deteriorated widely, re-roofing may make more sense than another patch. We assess the existing structure before discussing a replacement covering.
Tiles and slates change both the look and the weight of a roof. The right choice depends on the pitch, the supporting structure and the character of the property, particularly on older Sussex streets or where conservation controls apply. Ventilation also needs to work with the insulation in the roof space.
A new roof involves more than the visible tile or slate. Underlay, battens, ridges, valleys, verges, eaves and flashings all contribute to keeping rain out. We set out which of these details are included, along with access, waste removal and any work to gutters or roofline boards, so the full job is clear.
The condition of timber beneath the old roof is not always clear until coverings come off. If rafters, decking or other supports need attention, we explain what has been found and discuss any change to the planned work before it continues.

The ridge completes the covering
A straight run of tiles still needs a secure finish at the top of the slope. Ridge fixings and any ventilation detail should suit the roof’s construction, not simply its appearance.
Ask about new roofs & re-roofingQuestions about new roofs & re-roofing
When should a roof be replaced rather than repaired?
Widespread failure, repeated leaks or the condition of underlying components may make replacement more sensible. The decision should follow an inspection and a comparison of realistic options.
Can the roof's appearance be retained?
The roof shape and material choice can often respect the building's character, subject to suitability, availability and any applicable planning or conservation requirements.
What is normally included in a full re-roof?
A full scope commonly covers removal of the old covering, assessment of exposed support, suitable underlay and battens, new tiles or slates, and the relevant edge and junction details. Ask for each element to be stated in the specification.
Will I need planning permission to replace a roof?
Many like-for-like roof works do not need a separate planning application, but visible material changes, listed buildings and conservation areas can have different requirements. Check the property's status and the proposed materials before work is agreed.
Does re-roofing need Building Regulations approval?
Building Regulations approval is needed for many re-roofs. The roof build-up, insulation and any change in covering weight can affect what is required, so the requirements should be checked for the particular property before work starts.
