Flat & Pitched Roofs in Valencia
Waterproofing for Azoteas,
Insulation for Pitched Roofs
Valencia has a lot of flat concrete roofs — azoteas — used as laundry areas, terraces or simply left unused, plus plenty of pitched roofs on villas and older houses. Each type needs a different approach, and we treat them differently rather than applying one fix to both.
- ✓ Flat azotea waterproofing and re-tiling of the walkable surface
- ✓ Pitched roof insulation fitted from inside, through the loft
- ✓ Roof terrace waterproofing before laying new outdoor flooring
- ✓ Insulation upgrades for lofts being converted into usable rooms
- ✓ Fixing recurring leaks around chimneys, skylights and roof edges

Structure Damaged Instead?
Roofing & Roof Replacement in Valencia
When You Need a Full Roof Replacement, Not Just Waterproofing
If the rafters are rotten, the roofline is sagging, or a large area of tiles and battens has failed, refreshing the waterproofing alone will not solve the problem — the roof structure itself needs rebuilding. In that case, our Roofing & Roof Replacement service is the right fit; it is a separate scope of work with its own quote. If your rafters and battens are sound and only the membrane, tiles or insulation have failed, the lighter waterproofing and insulation project on this page is usually enough.
- ✓ Rafters or roof timber showing rot or movement
- ✓ Roofline visibly sagging or uneven
- ✓ Large areas of tiles or covering missing, not just a few spots
- ✓ You are planning a second-storey addition on top
- ✓ Recurring leaks even after previous waterproofing repairs

Local Insight
Shared Azoteas and the Comunidad de Propietarios
In many Valencia apartment buildings, the flat roof — the azotea — is a common area owned jointly by all residents, not by whoever lives on the top floor. That means waterproofing it usually is not a private decision: it needs approval from the comunidad de propietarios, the community of owners, often through a vote at a community meeting, and the cost may be split among all owners rather than paid by one flat. Because it is classed as maintenance of a shared building element rather than a change to a private home, most azotea waterproofing projects only need a licencia de obra menor, a simplified minor-works permit from the local ayuntamiento (town hall), rather than the fuller licencia de obra mayor required for structural work. We can prepare the technical description the community administrator needs to bring to a vote, and handle the permit application once it is approved, so the paperwork does not slow the project down.
Client Reviews
Real Feedback from Our Clients

★★★★★
Our top-floor flat had a damp patch every autumn. Turned out it was the building's azotea, not our roof — they waterproofed the whole shared roof and coordinated with the community administrator on the cost split.
★★★★★
Insulated our loft from the inside without touching a single tile on the roof. The house feels noticeably cooler in summer now.
★★★★★
Honest about it — told us our roof structure was fine and we did not need the full replacement we had been quoted elsewhere, just new waterproofing. Saved us a lot of money.
Roof Waterproofing & Insulation
FAQ
How do I know if I need roof waterproofing or a full roof replacement?
If the roof structure — rafters, battens or the concrete slab — is sound and only the waterproofing layer, tiles or insulation have failed, waterproofing and insulation is usually enough. If there is rot, sagging or widespread structural damage, you need a full roof replacement instead.
+
Can you waterproof a flat roof (azotea) without removing the existing surface?
In most cases, yes. We can apply a new waterproofing membrane directly over a sound existing surface after preparation, though badly damaged areas may need to be stripped back locally before the new layer goes on.
+
Does insulating a pitched roof mean removing the tiles?
Not always. Insulation can often be fitted between the rafters from inside the loft space, without touching the tiles at all. If access from inside is not possible, we lift and refit sections of the covering, but the rafters and structure stay in place.
+
Who is responsible for waterproofing a shared azotea in an apartment building?
The flat roof of an apartment building is usually a common area owned by the whole comunidad de propietarios (community of owners), so waterproofing it normally needs community approval and the cost is often shared, rather than being one owner's private responsibility.
+
Do I need a building permit for roof waterproofing and insulation?
Most waterproofing and insulation projects that do not touch the roof structure only need a licencia de obra menor, a simplified minor-works permit from the local town hall. We can prepare and submit this as part of the project.
