Shed Roof Leaking Through Nails

Sometimes the water shows up at a ceiling spot distant from the leak.

Shed roof leaking through nails.

I didn t get any black residue on my hands at all i used felt nails a short one for the top of the roof and the longer ones for securing the overhangs. Smaller nail holes will be permanently fixed by this method standard roofing nails would be either 3 8 inch or 1 2 inch making a hole. And just one rusted out nail can cause your roof to leak every time it rains. As i said those waterproof mastics and adhesives help glue felt down but on a shed where the structure is moving and felt vibrating in the wind they are not suitable to use as waterproofing in my opinion.

Morning all i re felted my pent roof shed yesterday. How to fix nail holes in a roof any type of shed whether it is made from wood metal or a combination of wood and metal sheets will eventually leak as weathering occurs over time. I think the rain is coming in through a couple of gaps somehow by the nails i used clout nails maybe if i put another lot of felt on roof but be more careful on the angle they go in dawn78.

Discussion in general gardening discussion started by dawn78 may 15 2009. All went well until i went into the shed looked up and saw that the clout nails had come through the roof by a couple of mill. I secured the side overhangs with timber which i screwed on i m praying that i ve done it properly and it won t leak as i ve been suffering with it leaking like a colander for about 3 years. Even on a normal shed roof i have seen water drive under a 4 inch nailed lap.

Roof nail leaks can happen when roof nails have been loosened slightly from high winds or have simply pulled out over time. Some roof leaks are tough to locate. These nails will eventually rust. Is this a problem.

If your ceiling has a plastic vapor barrier between the drywall and the attic insulation push the insulation aside and look for flow stains on the plastic often water runs to openings in the vapor barrier such as at ceiling light fixtures.
