Partial renovation
Roof and terrace waterproofing in Gran Canaria
Most of the leaks we get called to have already been repaired once or twice. The reason is nearly always the same: someone sealed where the stain was, not where the water was getting in.
Water travels along the cavity or the fall before it shows. Finding the real entry point is half the job.
01 — Scope
What it includes
01
Locating the entry point
Before quoting anything.
02
Removing failed layers
Waterproofing laid over waterproofing always fails eventually.
03
Forming falls
If water stands, any system will give up sooner or later.
04
Waterproofing system
Liquid membrane, bituminous sheet or rubber depending on use and foot traffic.
05
Upstands and outlets
Junctions with parapets and drains — where it usually gets in.
Typical timeline: 1 to 3 weeks.
02 — Price
What it costs
Liquid membrane
Bituminous sheet with protection
Including new falls
Indicative ranges, excluding IGIC (Canary Islands sales tax). The real figure depends on the starting condition, the specification and access. Only a site visit gives a reliable number.
03 — Questions
Frequently asked
- Can you find where the water is getting in?
- Yes, and it is the first thing we do. Quoting a waterproofing job without knowing the entry point is guessing.
- How long does waterproofing last?
- 10 to 20 years depending on the system and whether the roof is walked on. The specific guarantee is written into the quote.
