ONDULINE ISOLINE ROOFING UNDERLAYS

 


 

ONDULINE ISOLINE ROOFING UNDERLAYS durably safeguard your house, your family and your belongings. Even the highest quality roof tiles may not be durably waterproof; they can move or break due to outside elements like frost, humidity, high winds, and an accumulation of dead leaves or snow. To ensure you can rely on your tile roof to keep your home safe and dry day after day, year after year, you need a long-lasting waterproofing solution.

We designed our roofing underlays system to be​ ​fully waterproof ​and to ​repel any water that might seep through roof tiles, helping to keep the building ​100% leak free​.

HOW DOES IT WORK ? 


 

 

 

For new and renovation: 

Large waterproofing sheets are laid under the ties, creating an effective roof under your roof. The roofing underlays system repells any water that might seep through the tiles. Installation is extremely fast, and the interior of your house will remain dry throughout the work.
C'est une garantie physique et durable pour la couverture, empêchant toute infiltration dans le bâtiment. 

A solution that fits any tile:  

No matter the type of tile you wish to use, the ​ONDULINE ROOFING UNDERLAYS ​will fit! It can be used with any type of clay or cement tile in a range of shapes and profiles, and it will fit any roof, regardless of  shape or pitch.

Preserve the original style of historic buildings

If the original tiles are high-quality and well-preserved, they may be able to be reused on top of your new ONDULINE ROOFING UNDERLAYS, maintaining the original historic aesthetic. ​In that case, Onduline roofing underlay will act as the primary waterproofing material, while the tiles protect the building. 

 


Reusing original tiles also means ​significant savings in your renovation budget​. Please contact a roofing profressional for advice about Onduline solutions.
