Porch Roof Types: Flat, Pitched & Tiled 2026

Porch roof types compared

A flat porch roof (finished in felt, GRP fibreglass or EPDM rubber) is the cheapest and suits a small canopy or a modern house. A pitched gable porch roof gives a classic peaked look, while a hipped version has slopes on all sides for a softer profile. A lean-to pitch is a simple single slope. Pitched porches are usually finished with tiles or slate to match the main roof.

Porch roof cost 2026

As a rough guide for 2026, a simple flat roof canopy costs around £600–£1,500, while a full pitched, tiled porch roof runs £1,500–£3,500+ depending on size, structure and whether new supporting walls or a lintel are needed. Matching the tiles to your existing roof and adding decorative details push the figure up.

Do you need planning permission for a porch?

Many porches are Permitted Development if the ground-floor footprint is under 3 m², no part is more than 3 m high, and no part is within 2 m of a boundary that faces a highway. Go beyond those limits, or live in a conservation area or listed building, and you will usually need a planning application. Always confirm with your local authority first.

How to choose and compare quotes

1. Match the style to your house

Pick a roof shape and covering that suit the age and look of your home — it is the first thing visitors see.

2. Choose the roof covering

Tiles or slate for a pitched porch; GRP or EPDM for a low-maintenance flat canopy.

3. Check permitted development limits

Confirm the size, height and boundary rules before you commit so you do not need retrospective consent.

4. Get three like-for-like quotes

Compare on the same roof type, covering and structural work so you judge quality, not just price.
