Replacing the roof covering: do you need a permit in Portugal?

Independent site: we are not a public authority, and this is not legal or tax advice.

Replacing roof tiles or covering with a material that improves energy efficiency is exempt if the finished look is identical to the original. A like-for-like repair is conservation work and is exempt too.

Answer

Exempt if the finished look is identical to the original

Condition

The new covering must improve energy efficiency and give an identical outer finish

Like-for-like repair

Repair that keeps the roof as built is conservation (art 2(f) and 6(1)(a))

Changing the roof

A change to the shape, height or look of the roof is an alteration (art 2(d))

Before you start

Tell the council at least 5 days before work begins, even for exempt work (art 80-A).

Heritage exception

Minor-works exemptions do not apply to listed buildings, buildings in the protection zone of a listed building (window frames excepted), or buildings inside listed groups or sites (art 6-A(2)).

Council rules

Your council can add detail in its own building regulation where the law lets it, so ask before you start.
