Roofing regulations, FAQ
Do I need planning permission for a new roof? Usually not for like-for-like replacement, but altering the roofline, adding a dormer, or working on a listed building often does. Do I need Building Regulations sign-off? Yes for most re-roofing work involving insulation changes — a competent roofer will handle or advise on this.
Skylights and roof windows
Adding a skylight to an existing roof means cutting into the structure and properly flashing around the new opening — a common source of future leaks if not done to the window manufacturer's fitting instructions exactly. Existing roof pitch and rafter spacing affect what size window can go where.
Common roofing jobs
Roofers handle full re-roofs, repairs to individual slipped or cracked tiles, flat roof replacement, guttering, fascias and soffits, and leadwork around chimneys and roof valleys. Emergency work — storm damage, a leak during heavy rain — is usually handled separately from planned re-roofing.
Roof orientation and solar suitability
A south-facing roof slope generally gets the most useful sun for solar panels, though east/west-facing roofs can still work reasonably well. A roofer or solar installer assessing suitability will look at pitch, orientation, shading from nearby trees or buildings, and roof structural capacity together.
Guttering and fascias, when to replace
Guttering that overflows in heavy rain, sags, or has visible cracks is worth replacing before it causes damp at the roofline or foundations. uPVC is the common low-maintenance choice; timber fascias on older properties need repainting periodically or replacing with uPVC to reduce upkeep.
Why roofing work is weather-dependent
Roofers generally can't safely work in high winds, heavy rain, or icy conditions, so scheduled roofing jobs sometimes shift by a few days around bad weather — factor this into timing if you need work finished by a specific date, particularly in autumn/winter.
Roofing emergencies — what to do
For a leak during a storm, contain the water inside (a bucket, moving belongings) rather than attempting a repair on a wet or high-wind roof yourself. Photograph any visible damage from the ground for an insurance claim before it's repaired. Tarping over a damaged section is a common temporary fix while a full repair is arranged.
What affects the cost
Cost depends on roof size and pitch (steeper roofs need more scaffolding and take longer), the material (slate costs more than concrete tile), access, and whether the existing roof structure (timbers, felt) needs work too, not just the visible covering. A straightforward repair is quick; a full re-roof including scaffolding commonly takes 1-3 weeks.
