Why
is it advisable to remove moss, algae and lichens
from the roof, facade or pathway?
While some homeowners like the look of moss on
their roof, this growth may have a damaging effect
on the stability of the substrate structure. The
moss and algae roots can grow into the building
material and absorb water. This causes most of
the problems, because in freezing weather building
materials often expand. This leads to frost chipping,
the surface protection is destroyed and the weathering
process far advanced.
ALL building materials need protection against
weathering:
- A concrete roof tile is usually protected
by a coating in the factory of the tile manufacturer,
but after some years the surface must be renovated
with a roof coating.
- • Clay tiles for roofs or facades absorb
a lot of water. They are also prone to strong
algae and moss growth. One can continue to clean
the roof by removing the moss or algae, or waterproof
the surface so that moisture can no longer penetrate.
Waterproofing protects your roof against growth
of moss and lichens as all green growth requires
moisture to grow.
There are many solutions for protecting the roof
surface against green growth, but:
Our solutions were developed and tested by experts.
They have been used successfully for many years
without damaging the surface of the roof or the
environment.
Why do we have algae, moss and lichen problems?
Green growth has been increasing over the last years
particularly in urban areas. The reasons are mainly
to be found in the greatly improved emission values
of air. (CO2). |
