Metal Roof Repairs

Metal roofs can deteriorate over time, especially if regular maintenance was not carried out on the roof. Metal roofs can be repaired by either replacing dysfunctional roof sheets or by applying a waterproofing product to repair compromised areas. The type of waterproofing product to be used on the repair of a metal roof is of vital importance. Many contractors prefer to use a torch on membrane to repair affected areas. Other products like bitumen mastics can be used together with a hydrophobic carrier to solve minor problems.

The typical areas where metal roofs fail are at the screws that fix the roof onto the roof truss. Inadequate roof screws that do not seal properly are the cause of this problem. Another area where metal roofs fail are on the laps of the roof sheeting, if there is not a sufficient lap over the next sheet water may find its way in at that point. Incorrect pitch can also cause problems on a roof. If the pitch of the roof is very low and drainage is slow water may find its way in, at various places. Metal roof sheets that span the entire length of the roof are best since they require less overlaps. A metal roof with shortened sheets can result in more overlaps and essentially more potential problems.

Incorrect flashings are another common place where metal roofs leak. If the metal flashing is not chased into the parapet wall or not properly counter-flashed problems could arise at this junction. The metal flashing must also be fixed by means of nails to the parapet wall especially if the roof is situated in a high wind area. Proper counter-flashing then needs to occur to flash off the metal flashing itself. Metal roofs can function optimally if they are erected correctly. Repairs to metal roofs can also be completed properly if the necessary skills exist to diagnose roof repairs together with good product selection and workmanship.
