Flexim Roof Putty

Flexim roof putty is a ready-to-use alternative to traditional mixed roofing mortar for suitable roofing details. The existing product description identifies a linseed-oil-based, flexible compound supplied in preformed strips. Available here in Grey, Black, Brown and Red, it is particularly useful where the colour of a visible roof repair matters.

Ready-to-use flexible roof putty for detailing and repairs

• Ready-to-use, flexible roof putty rather than conventional sand-and-cement mortar
• Linseed-oil-based formulation identified in the current listing
• Selectable colours: Grey, Black, Brown and Red
• Existing guidance lists roofing details such as ridges, flashings, valleys and roof windows
• Can be shaped by hand for applications approved by Flexim

Choosing and using Flexim roof putty

Check the condition of the roof covering and identify the source of any leak before selecting a repair product. Flexim must not be used as a substitute for structural repairs, unsuitable fixings or damaged roof coverings. Prepare the surfaces and follow the manufacturer's current guidance on application conditions, supporting tiles, thickness and curing.

Practical considerations for roof maintenance

The condition of the surrounding roof often determines whether a local putty repair will last. A loose ridge, defective flashing or broken tile may need replacement or mechanical attention rather than a surface seal alone. Clean and prepare the application area as instructed by Flexim, and check that the compound is suitable for the roof element being treated.

Colour choice can be important on exposed details. Grey and Black often sit discreetly with darker coverings, while Brown and Red may help with warmer tiles. Select the nearest available finish rather than assuming one colour matches every manufacturer. Work at height should be planned with suitable access and fall protection; product convenience does not remove roofing safety requirements.

Can roof putty replace missing fixings?

No. Where the roof design requires mechanical fixings or specific ridge and verge systems, use the specified fixing method and treat putty only as appropriate under the manufacturer's guidance.

Frequently asked questions

Is Flexim the same as traditional roof mortar?

No. The listed product is a ready-to-use flexible roofing compound, not a mortar that needs sand, cement and water mixed on site.

Which Flexim colours can I order?

The current variants are Grey, Black, Brown and Red. Match the colour to the surrounding tiles or detail.

Can Flexim fix every roof leak?

No. The source of the leak, condition of the roof covering and suitability of the material need checking first. Follow the manufacturer's approved uses.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
