Re-bedding the mortar on your roof is a key part of maintaining a healthy roof and essential to the health of the rest of your property. Especially for homes over 25 years in age, you very well may have cement mortar for the roof pointing. The cement after a certain amount of time is prone to damage including cracking and splitting. The main implication of mortar that is cracked and in need of mortar re-bedding is the fact that tiles can come loose and shift out of position.

What Is Mortar re-bedding?
The roofs bedding and the roof pointing are two key ingredients in the structure of your roof. The mortar bedding cements the roof tiles in position whilst enabling the roof pointing to have a tight seal and hold.
It probably sounds obvious but mortar re-bedding is the process of replacing the mortar and repointing changing the pointing.
The bedding isnโt always made of mortar but typically is so we offer mortar re-bedding as a regular service to the Maiva client base. Mortar has more recently been swopped on newer builds to use a more flexible compound for roof pointing.
The main problem when you hit issues with mortar bedding or pointing, like most problems with roofs is the inevitable leaks that occur which as we talk about on the Maiva website is something that when left unchecked leads to serious damage to your home and underlying structural damage if left long enough.
Risks of not carrying out Mortar re-bedding
Mortar re-bedding can ensure your roof and property is safe from mould growth which results from moisture creeping into the structure from minor cracks and from water damage. No matter how minor the breakage, crack, split, or damage the mortar is the first entry point for moisture and leaks. If and when water or excess moisture gets inside your building, there is a greater risk of mould growth, which can lead to several additional issues.
One of the real challenges with mould is the speed it can spread through the property, causing damage to the building, but also posing a threat to the health of those living in the property and itโs not quick to remove either so best take measures to avoid at all costs.
