Carefully Navigate Your Roof To Find Your Metal Roof Leak Repair

You will need to use your extension ladder to get onto the roof. Before you go up the ladder, take a look at your boots and clear them of any dust, rocks, or other abrasives that can damage your metal. When you get onto the roof be sure to not step between rows of nails. Step on the nail rows and tread lightly. Doing this will prevent your metal panels from bend damage.

To efficiently navigate on your roof, identify areas where the panels rest on underlying battens or decking. These will support the panels and prevent any bending.

Locate The Source Of Your Metal Roof Leak Repair

To successfully perform a metal roof leak repair, you have to be able to locate the leak. One of the first signs of a leaking roof is punctured holes. Debris and rusting can cause metal roofs to grow weaker and contract. You will need to take notes of any holes or panels that have slid down due to contraction and expansion.

Look around for missing screws and missing material. Inspect the edges and periphery of the roof for these things. Be sure to check the seam transition points. These are where one panel connects to the other panels on the roof. Check if there are any gaps between them.

Remove and Replace Screws To Fix A Metal Roof Leak Repair

If you come across any loose screws or rusty nails, remove/loosen them with the nail bar. Once you remove a screw replace it with a 1 ½ inch aluminum screw nail. Use the hammer to drive the screw nail into the panel. Do this until all loose screws and rusty nails are replaced.

If you are having trouble removing any rusty nails, don’t try and force them out. Instead, use the cordless drill with a screw drill bit and create a hole. After this is done, drive a 1-inch galvanized steel screw to secure that section. This will help you avoid further nail rusting and loosening.

How to Deal With Gaps That Warrant A Metal Roof Leak Repair

Many contractors will tell clients to get rid of a metal roof that is damaged or loosened. Of course, a ⅛ inch gap is enough to cause severe damage to a metal roof. However, you can deal with gaps just by cleaning off debris and rust on the surface of the panels.

The metal-roofing base coat helps prevent water from flowing into the gaps. Apply a single layer of the base coat. Then you will need to cover it with glass-membrane fabric (cut it to size). This prepares the gap urethane cement.

Re-Apply Roof Cement For A Temporary Metal Roof Leak Repair

Before applying roof cement, you need to make sure you found all damaged sealants. Also, make sure you have applied the metal roofing base coat and the glass membrane fabric roof patch. Now everything is screwed in tightly and each gap is prepared for better sealing. Since this is done you can now apply urethane cement to seal the leaks.

Apply a coat of cement over the whole area. An extension of 6 inches is good enough to secure the holes and gaps.
Now you are done! Only 6 steps to perform a successful metal roof leak repair.
