| Repointing |
Roof
tiles and mortar joints have to be checked every other year at least. Tuckpointing simple mortar cracks can avoid
leaking roofs and costly re-roofing jobs. Pay extra attention to ridge tiles as
they are exposed to weathering from all sides and may show some cracks in the
mortar joints before other tiles on the roof. If cracks are exposed in the
mortar between ridges tiles, the options are replace the joints or do something
with the ridge tile otherwise it will look odd.
If the
cracks are little and the tiles seem tightly bedded then repointing the mortar
is the best option. If the cracks in the mortar are big as the mortar joint and
the ridge tile look like to have some movement, it is a better idea to replace
the whole tile rather than repointing. If you do some work on a tile that is no
longer tightly bedded, then repair will not last very long and the crack will rapidly
reoccur.
Most of
the expert masonry repair experts assume that they can match mortar by just
simply matching the color of mortar with pigment or stain, and some try to go
with the sand. While this may work generally for them, it only works because
the client does not know that it was wrong and neither party understand the
problems this technique can cause. This issue occur most often in right-to-work
states that need no license for masonry repair and city codes do not implement
a standard of repair that narrates to this issue.
