Seal Standing Seam Roof Leaks

If the slope is less than 3 12 you ve likely found the source of the leak.

Seal standing seam roof leaks.

The stress leads to the breakdown of the flashings at the penetrations which results in roof leaks. Metal roof systems are constructed by attaching individual metal panels together at the seams. Leaking metal roof stack sealed on a standing seam roof. Failed sealant or butyl tape sealants and butyl tape are used to seal out water dirt and other debris that could compromise a metal roof.

Non skinning non drying butyl sealants are the primary sealant in standing seam roofs and the joints of insulated metal panels. Leaks in wooden roofs are commonly caused by a gap between the panels which move during expansion and contraction. The expansion and contraction on this standing seam metal roof caused an expansion in the fastener holes. Designed to stay soft and flexible they ensure a positive seal when jointing roof or wall panels.

As weather gets warmer water is observed dripping out underneath of overhang sofit on low part of the roof. Step 2 fill a caulking gun with a watertight polyurethane or oil based sealant and hold it at an angle to insert the product directly into the gap. My guess is the entire roof is leaking at the standing seams and water is sheeting down roof plane over underlayment. Butyl caulk tape is installed at the fastener bolt nut while at the same time allowing the drain channels to continue to flow.

Eventually ice builds up over top of the seam. Once the metal roof systems are installed they are very difficult to remove and disassemble. However there are quite a few commercial roofing systems that can be installed on slopes of 2 12 or greater but only if they have a standing seam. Actually when a standing seam metal roof has a leak it is commonly at some type of flashing area.
