What flat roof work do we do in Chichester?

Flat roof repairs

Flat roofs in Chichester face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.

Balconies and roof terraces

Door thresholds are a common reason for balcony work in Chichester. Where a door was fitted with a low step-out and no drainage channel, water driven against the frame finds its way under the sill. Re-waterproofing gives the chance to rebuild that detail properly.

Single-ply membrane roofing

Single-ply also works on an extension or garage in Chichester if you want a light, clean finish in a pale colour. On small roofs it is usually adhered, and while it can cost more than EPDM, it gives the same welded seams and details found on commercial roofs.

What flat roofs are typical in and around Chichester?

In a town like Chichester flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and terraced streets with flat-roofed rear kitchens and bathrooms. Local weather shapes the specification. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Chichester?

Where approval is needed it goes to Chichester District Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.

Flat roofing in Chichester: questions

Do you cover Chichester?

Yes, including postcode districts PO19. Send your postcode with your enquiry and we'll arrange a survey.

Do flat roofs in Chichester need building control approval?

Often. Replacing more than half of a roof over a heated room usually means insulating it to current standards and notifying building control, and structural changes need approval too. In Chichester that's Chichester District Council building control, or a registered building control approver. We tell you at the survey and handle it.

Can you repair a leaking flat roof in Chichester?

Yes. We trace where the water is actually getting in first, because the leak inside is rarely under the defect outside, then repair with materials compatible with your roof.

What's the best flat roof system for a house in Chichester?

For most garages and extensions it's EPDM or GRP; torch-on felt is the budget option and liquid suits detailed or overlay jobs. We recommend one at the survey.
