Mold typically
develops as the result of algae growth. Due to the monsoon season and humid
weather, algae may take hold and quickly grow on the roof. Ken Julian says that this may
cause the roofing materials to remain damp, subsequently promoting rot. As the
rot sets in, so can the mold. Moreover, even with no rain, just warm and humid
weather conditions may facilitate fast mold growth. Roof mold tends to thrive
in areas that are shady and moist. Hence, mold usually takes place in the
northern part of the roof and the areas that remain in shade for the most part
of the day.
The lifespan of a
typical residential roof generally ranges from around two to five decades, if
the homeowners manage to maintain it properly. Ken Julian remarks that a lot of
homeowners underestimate the problem of mold and allow it to fester, which
considerably reduces the longevity of the roof. Mold growth on roofs is among
the most expensive problems that homeowners may face, can it can considerably
impact the structural integrity of the roofing and facilitate the need for a
replacement. Mold is most likely to develop on wood and drywall surfaces where
water has been absorbed.
There are many
reasons why removing mold from the roof as soon as possible is extremely
important. Here are a few of those
reasons mentioned by Ken Julian:
- Mold
can travel: Mold may get wash off from the roof due to rain and get
tracked inside the house. Mold growth inside the house may create health
issues for the residents. Moreover, in case there is a good amount of
rotting on the roof due to moss, mold might be able to penetrate roofing
materials. Mold causes wood rotting and erodes asphalt in shingles. It can
even spread onto adjacent structures.
- Roof
mold is unsightly: Roofs are among the most visible aspects of a house.
While driving down the street, it is possible to notice the roof of a
house from a distance. Mold is usually black and creates ugly, streaky
stains on the roof. These stains can subsequently make an otherwise
beautifully designed home look damaged and neglected.
- Mold
is stubborn: Mold is both persistent and pervasive as a fungus. The more
entrenched mold becomes on the roof, the harder shall it would be to
control. One should try to clean the mold from their roof as soon as they
first see it, or have a professional roofer to fix the problem,
- Mold
can attract rodents: Roof mold often provides an inviting habitat for a
variety of rodents, including rats, squirrels and mice. They usually climb
up gutters to reach the roof. A damp, soft and moldy roof allows the
rodents to chew on the roofing materials, ultimately causing severe
damage. They may even cart off portions of the roof to create nests.
Mold damage may
become irreparable if not fixed in time. It is better to get in touch with an
experienced roofing contractor for assistance.
