Tejados Madrid LISER

I've had leaks and unbearable heat in my attic my whole life. I finally decided to replace the entire roof and trusted this company. Delfín, the owner, gave me excellent advice, recommending a complete system with insulation and waterproofing. I couldn't be happier; they're experienced and the price is very reasonable.

After requesting several quotes to renovate the roof of an old, dilapidated house, they offered me the best solution. They are highly professional, do excellent work, are reliable and punctual, and their quality-to-price ratio is among the best in the Madrid area.

Delfín renovated the roof of our apartment building, and we've had two years without leaks and with good insulation. They installed two layers of XPS insulation, a waterproof membrane, and new mixed tiles. A very affordable and long-established company.

Serious and dedicated professionals. We had leaks in our roof and they offered us the best price-quality ratio. It's true we had to wait a few months as they're quite busy, but once they started, they didn't stop until they finished, which was much appreciated since it was the rainy season. Roof completed in October 2024.

I called LISER for a solution to the leaks we've been experiencing for years. The solution they offered us, to save money and reuse the Arabic tile I already had, was to remove the tile, install Onduline as a waterproofing and insulation layer, and finally reinstall the tile. The result was satisfactory.
