How to fix a leaking flat garage roof.

Sweep debris away from the seam edges that you are repairing using a heavy broom. Start low soaking the area just above where the leak appears in the house. If you take that step be sure to cover the nail heads with tar roof sealant or peel and stick flashing patch. Fill a bucket with warm water.

For example soak the downhill side of a chimney first then each side then the top on both sides. Use a sponge to wash away as much dirt as you can along the seam that is leaking. When the membrane is completely dry apply the appropriate roof repair material such as roof cement tar or peel and stick patch. Clean the area where you found the garage roof leaks.

If a leak is difficult to find enlist a helper and go up on the roof with a garden hose. For example if an old felt roof is covered in moss loose rock chippings and lichen remove. Isolate areas when you run the hose. The patch should be adhered from the centre over the hole outwards with a firm hard roller.
