Metal Roof have become popular in a short span of time
around the States. The main reason for its popularity is the uniqueness in
style and the range of colors and designs in it. That’s why people tend to opt
out for the metal roofs. But it is not a mere aspect of exquisiteness in
designs and styles rather there are some drawbacks of the metal roofing as
well.
Metal roof leaks are some of the
most common problems in context with the defects of metal roofs.
When it happens a leakage issue then the roof specialist becomes the cause of relief to get rid of this
panic issue.
What are The General Metal Roof
Leaks?
Metal although being non-permeable doesn’t let the water pass
through it. Therefore, leakage from pure and undamaged metal is quite
impossible. But still there are some problems out there, where the metal roof
leakage happens out of nowhere.
Following, we are going to discuss some
common reasons of metal roof leaks.
1.
Metal
Roofing Screws
Metal roofs are joined and bound with the help of metallic screws. These screws are engraved within the metal and its lower surface. Although
along with metal roof screws there are fitted rubber rivets and bands around
the joints so that leakage couldn’t occur. But still sometimes, the rubber
washers and the gaskets wear down with the passage of the time. That’s where
water diffuses through these holes. This happens because of over driven screws,
under driven screws and screws that have missed the metallic strut or wood
foundation underneath it.
2.
Stack
Flashings Leaks
Sometimes, the metal roof leak is due to the stack
flashing's foundation cracks or spaces. This area is very prone to leaks on a
metal roof as this is the very area around stack flashings where vent pipes and
chimney pipes meet. So, the Stack flashings are actually the “boots “or
flashing's around piping that take out of the metal roof. HVAC vents, air vents,
and plumbing pipes all have to vent and come via the metal roof.
3.
Missing
Sealants
Metal roofing panels are conjoined together with sealants
that are used to fix the panels. These sealants can wear down under trims such
as metal reg lets, pitch pans and Z flashing. When the panels get rusted then
the sealants often lose their strength and come intact with water. Since the
leakage starts occurring.
4.
Curb
Flashing
The metal roof doesn’t stand alone with panels and wood
foundation, rather there are some flashing that make their ways through panels
of the metal roofing. Water often accumulates under the unit and “stands
“behind the flashing, which subsequently erodes sealants and starts leaking. The
more you block, seal, caulk or tar the uphill side, the more water it will hold.
This case of the metal roof leak is difficult to handle without removing metal
roofing panels and starting over again with new panel installation.
5.
The
Metal Panel Seams and Laps
Seams and laps are two consecutive parts of the metal roofing which join the metal panels with each other. A Butyl tape is used to
stick the panels with each other. So, when the panel starts losing then laps
and seams definitely get asunder which causes the common metal roof leak.
