Quick Fixes For Metal Roof Systems – Roofing Newsletter

The three previous columns in this series have sought out easy fixes for conventional membrane roofing systems. This month, well look at metal roofing systems.

Repairing Metal Roofing

Since metal roofing is produced from continuous coils, we can with considerable confidence state that the metal sheeting itself is not leaking. As a result of that far-reaching conclusion, we then immediately focus on the rest of the system .

Since there are two basic types of metal roofing: those that are expected to shed water and those that resist standing water , we need to address each separately. .

If the underlayment membrane is defective and is letting water enter the building envelope, repairs would require that the metal panels be removed and the membrane resealed. New penetrations in the roof panels, such as for HVAC equipment, conduit, etc., may prove to be the site of leakage, as the underlayment was penetrated and not sealed: There is no quick fix, as the metal panels are really not designed to keep water out.

How About Those Big Holes?

Penetrations through standing seam metal roofs can be a significant source of leakage.

The Metalmag article also illustrates that penetrations cannot effectively be sealed if they penetrate the raised seam of the panels. The fix: Move the penetration over a few inches so it is centered in the panel. Penetrations that cut through the seam may also compromise the structural performance of the roof panel.

Other Reasons Why Metal Roofs Leak

Loose fasteners are another typical reason why metal roofs may leak. Tightening fasteners is part of the normal maintenance routine for metal roofs about every 10-15 years. If you live in an area with a lot of snow or freezing rain, then you may need to tighten the fasteners more frequently, as water expands when it freezes and can loosen the fasteners more quickly.

Another possibility for your metal roof leaking is a gap in the seams where the metal panels meet. Seams can separate over the years from severe weather conditions and old age. Small gaps can be fixed without replacing the panel, but large gaps and dents may require that section of the roof to be replaced.

Lastly, oxidation in your metal roofing can turn into holes that allow water to leak if not restored or repaired early on. If you notice your roof becoming dull and faded, or the paint has started to oxidize, you can restore the metal by washing it and applying a new protective coating to seal the unprotected metal.

Metal Roofing Issue #: Fastener Issues

The metal paneling on your roofing system is brought together by one of two different types of fasteners: clips or rubber washerfasteners. The clips fasten in a way that conceals the metal seam laps. They typically involve a sealant to bind the metal paneling of the entire roof together.

Fasteners with rubber washers are self-drilling and can be put as close together as every two square feet. By putting them in close proximity, the seam laps of the metal paneling are held flush without the additional need of a sealant or butyl tape.

Over time, these fasteners can pop out, leaving holes or gaps in the metal seam laps, which can allow water in and paves the way for other issues down the road.

Some metal roofing systems are much better at holding a tighter seal, such as standing seammetal roofing systems.

Once the patch has been measured, place it over the hole being repaired. Take a pencil and outline the patch onto the roofing. Remove the patch and examine the outline to make sure the patch will overlap by at least 2 inches in all directions past the edges of the damaged area.
