Ceiling leaks When it Rains, Roof Looks Good

ceilingleakrainroofshingles

enter image description hereMy ceiling drips water sometimes when it rains (especially when it rains hard). It seems inconsistent though, so I think that it may have something to do with the angle at which the rain comes in. The leak is at the apex of my ceiling, so I know the leak must be just about directly above that spot on my ceiling. My roof is about 10 years into its life span, but it seems to be in good shape. I got on-top of my roof, but couldn't see anything wrong with the shingles near the spot that leaks. How should I proceed? Should I buy some more shingles and put them on top of the others at that same spot on my roof? Should I take up a bucket of water and see if I can reproduce the leak?

Since the general vicinity of the leak is at the peak of the roof it definitely decreases the amount of time pinpointing the exact location. Depending on your roof pitch it is quite possible for rain to be blown under the roof shingles. The easiest why to repair the opening is with roof cement. Any brand that is petroleum based will work. And because you know the general location start by checking each shingle to see if it can be lifted from the one below it. Shingles have a adhesive strip that bonds it to the one below. If you locate one gently lift it enough to smear a tablespoonful of roof cement and press back into place. Also be on the look-out for roofing nails that have worked their way through the shingles. Although rare nail 'pops' do occur on roofs. It maybe easier to remove the nail than risk damaging the shingles by hammering it back. Apply cement if you do. Check the cap shingles on the ridge line. U.V rays will desiccate the asphalt to the point it becomes crumbly. Look for any splits on the shingles and 'thread-bare' ones that have lost their asphalt particles from erosion. Trowel cement just enough to do the job (too much may soften or melt the shingles in heat prone climates.
