| Questions: |
Answers: |
| Is
it noisy when it rains? |
No! Residential
steel roofing is available in many shapes and forms. The forming
process provides not only strength, but when coupled with high
quality finishes, it absorbs and deadens noise. With the home
insulation standards of today, you will not notice any difference
to other roofing materials. |
| Is
it heavy? |
No!
Our installed weight of 1.25 lb / square foot is half the weight
of most asphalt and wood roofs and only 10% of a concrete tile
roof. |
| What
about fire? |
A steel roof is
non-combustible. Steel does not burn and offers various options
in its installation to upgrade the fire resistance of the homes
structure. Most roofing materials have fire resistant strengths
on one side only. Other heavier roof systems provide little
or moderate resistance during internal fires and can cause premature
roof structure collapse. Remember if an internal fire is at
the underside of the roof structure, metal will provide the
greatest degree of maintaining structural integrity and assist
in containing the fire. |
| What
about snow? |
The
degree of snow movement on the roof plane is dependent on the
slope, friction on the granular/pre-painted roof, cleanliness
and volume of snow. To provide protection around entrances and
exits use proper snow retention, or deflection products. |
| What
about ice? |
Ice damming can
occur on roofs where temperatures cycle above and below freezing
daily, or when warm and cold areas are both present. A Dura-Loc
metal roof will minimize this phenomena, but we recommend an
ice and water shield underlayment in known troubled areas as
a precaution. |
| What
about hail? |
Dura-Loc metal roofs have passed a
class 4 UL hail test. There have been occasions in a hail
belt where unusually large diameter (3") occurred, which
created some minor cosmetic damage. Dura-Loc panels can readily
be repaired or replaced if this were to happen.
|
| Can
I walk on it? |
Walking on any
roofing material is not recommended unless necessary. Walking
on wood or asphalt roofs loosens and cracks the shingles while
damaging the felts. Walking on a concrete roof loosens the fasteners
and stresses the hairline shrinkage cracks inherent in the product.
A steel roof is probably one of the most forgiving roofs to
walk on as they are designed to flex, and as long as people
walk in the flats over the supports, virtually zero damage will
occur. |
| Will
it make our home hot? |
No!
Steel absorbs and dissipates heat quickly. As with any material,
colour is the governing factor when exposed to sunshine. Installing
a steel roof on your home will reduce your energy requirements.
|
| How
long will it last? |
A steel roof is
a permanent roof system. With minimal maintenance it will last
as long as your house. |
| Should
I worry about lightning? |
No!
Metal roofing does not increase the risk of a lightning strike
in any way. In assessing the risk with any structure it is the
"probability" of a strike which is based in location
(i.e. Proximity with other structure, high ground etc.) that
is the governing factor. |
| Can
I paint it? |
Painting over
a new installation of pre-painted or granular steel roofing
is not recommended. All coil-coated paint films are formulated
for high heat curing process and may not allow good adhesion
between field applied paint and the original surface without
special preparation and paint. |
| Can
I clean it? |
An
occasional cleaning of metal roofs can extend the service life
and help to maintain the appearance of the finish (no different
than a car finish). For protected areas (i.e. overhangs) an
annual spring cleaning is recommended. Simply washing with plain
water using hoses or low pressure sprays is often sufficient.
