When do regulations apply?
Re-roofing and thermal upgrades
If you replace 25% or more of your roof covering, Building Regulations usually apply. Your contractor must notify Building Control and upgrade insulation to meet current energy efficiency targets in Approved Document L. The aim is to reduce heat loss, manage condensation and improve comfort.
Structural changes
Adding a dormer, changing from flat to pitched, altering rafters or strengthening the deck will trigger Building Regulations under Part A for structure. The design may need calculations by a structural engineer and checks for wind uplift and snow loads.
Weather, moisture and ventilation
Approved Document C and BS 5250 set requirements for moisture control. Your contractor must specify correct ventilation or a warm roof build-up to avoid condensation, mould and timber decay. Underlay choice and detailing at eaves, valleys and ridges must follow BS 5534 for slating and tiling.
Fire and boundary conditions
Approved Document B covers fire performance of roof coverings. Near boundaries the roof should achieve a suitable classification such as BROOF(t4). Flat roofs with openings or rooflights need careful detailing of fire breaks and spacing.
Electrical or solar works
Solar panels change roof loading and fixings. Design and installation must consider structure, wind resistance and weathering. Any electrical work must meet Part P, with testing and certification.
Asbestos in older roofs
Outbuildings and some older extensions can contain asbestos cement sheets. The Control of Asbestos Regulations 2012 require identification and safe handling. Licensed contractors are needed for higher risk materials. Never drill or disturb suspect sheets without a survey.
Planning permission in Midhurst
Many like-for-like re-roofs fall under permitted development, but there are exceptions. Midhurst sits within the South Downs National Park and has a conservation area with many listed buildings. If you change the appearance with new materials, raise a ridge line, add rooflights on a principal elevation or install a dormer, you may need consent. The planning authority is the South Downs National Park Authority. For listed buildings you will need Listed Building Consent for any works that affect the character, including replacing tiles, leadwork or roof timbers. Your contractor should help with product samples, heritage details and liaison before work starts.
Party Wall considerations
If your project affects a shared wall or party structure in a terrace or semi, the Party Wall etc. Act 1996 may apply. Notice and agreement are required before works proceed.
What your contractor must do to comply
Notify and certify
Your contractor should either notify your local Building Control or self-certify through an approved competent person scheme. On completion you should receive a Building Regulations certificate. Keep this with your property records as buyers and insurers often ask for it.
Follow standards and good practice
- Fixings and detailing to BS 5534 for tiles and slates
- Condensation control to BS 5250 with correct ventilation or warm roof build-ups
- Materials with UKCA or CE marking and suitable fire rating under Part B
- Insulation levels that meet Part L targets for energy efficiency
Health and safety on site
The Construction Design and Management Regulations 2015 apply to domestic projects. Your contractor takes on the client duties and must plan, manage and monitor the work. Expect risk assessments and method statements, edge protection, proper access, debris control and clear housekeeping. The Working at Height Regulations 2005 require safe scaffolding with tags and inspections.
Waste and the environment
Roofing creates waste tiles, timber and metals. Your contractor must use licensed carriers, segregate recyclable materials and provide transfer notes. Hazardous waste such as asbestos needs special handling and documentation.
Paperwork and protection
- Written quotation with scope, specification and programme
- Product warranties and an insurance backed guarantee where available
- Proof of public liability and employers liability insurance
