Is your roof quote complete?

Tick what the quote already says. See what is missing and copy the questions for the contractor. It stays in your browser: we store nothing.

The 16 things a roof quote should say

Tick only what is written in the quote. What is missing becomes a question.

Company and licence

  • The company must put its NIF and its licence number on contracts and invoices (Law 41/2015, article 17).

  • Check it on the IMPIC website. A certificate only covers works up to 40,000 euros.

  • It is a requirement of the licence. On a roof, the risk of a fall is real.

  • The technician who signs the statement of responsibility for the execution (Law 31/2009). If the job is exempt, tick it as met.

What is done

  • Without this, two quotes cannot be compared.

  • “Ceramic tile” on its own does not say which tile.

  • For products covered by a harmonised standard, the maker issues the declaration (Regulation (EU) 305/2011).

  • Check whether the price includes the removal.

  • Check whether it is in the price or extra.

  • Only companies authorised by the ACT, with an approved work plan, may remove asbestos. If the roof is not asbestos-cement, tick it as met.

Price and invoice

  • Without this split, the invoice may carry 23% instead of 6%.

  • The invoice should say “Taxa reduzida ao abrigo da verba 2.27 da Lista I anexa ao CIVA”, the owner of the works and the property.

Payment, dates and warranty

  • Paying 3,000 euros or more in cash is prohibited (General Tax Law, article 63-E). Pay by bank transfer.

  • Dates or time limits in writing.

  • For building works, the contractor answers for defects that appear within five years (Civil Code, article 1225). Ask for what the company guarantees in writing.

  • With the parties, the licence or certificate, the object, the price and the time limit (Law 41/2015, article 26).

Why an incomplete quote costs money

Two quotes can only be compared when they say the same things. If one includes scaffolding and removal of the old tiles and the other does not, the cheaper one may end up the dearer.

Then there is VAT: labour for repair or maintenance of a home carries 6%, but only if the quote and the invoice separate labour from materials and say which works they cover.

How to use it

  1. Have the quote in front of you, on paper or on screen.
  2. Tick each point that is written down. Do not tick what the contractor only said aloud.
  3. See on the right what is missing and copy the questions.
  4. Send the questions in writing and keep the answers.

What this tool does not do

It does not say whether the price is fair, does not judge the quality of the work and does not replace a technician. It only measures whether the quote says what the law and good practice ask it to say.

The references to the law come from our guides, each with its sources and the date they were read. The tool runs in your browser and does not store what you tick.
