How Can You Find The Source Of A Roof Leak?
When your ceiling begins to leak, you may logically assume that the source of the leak is on an area of the roof that lies directly above the leak. Alas, if only roof leak detection were so easy.
Water can travel a circuitous route from the roof along ceiling joists only to drip onto the ceiling in a completely different area from the section of roof that is responsible for the leak.
You need to perform some roofing detective work to ascertain the probable source of a leak in order to stop it in its destructive tracks.
What should you look for to determine possible sources of a roof leak?
There are various signs that may point you in the direction of your leak. You need to examine each part of the roof and repair anything that looks like a possible leak source, which include the following items:
If you see a puddle or section of pooled water on the roof, it indicates the presence of a low spot on the surface of the roof. When water collects on a section of the roof, it wears away the roofing material until it finds its way inside the home.
You will need to remove any standing water with a hard-bristled broom or shop vacuum. If you use a shop vac, be sure to remove the filter before vacuuming up water. Empty the shop vac frequently, because water is surprisingly heavy, and you don't want to hurt your back or throw yourself off balance when emptying the vac and perform a short and painful dive from the roof.
When the standing water is removed, you can fill in the low area with roofing cement. While it is difficult to apply in standing water, it can be applied to a wet roof with no problem. This is a very thick and noxious substance that sticks to everything, but is very effective in sealing your roof. Apply it with a trowel, spreading it evenly until it meshes with the roof surface.
Loose or missing roofing nails
Temperature changes can cause roofing nails to "pop up," or protrude from the roof. They may even pop out and leave an empty hole, which is an open invitation for water to seep into the home.
Protruding nails must be hammered in and missing nails replaced, with a small dab of roofing cement placed atop the troublesome nails, both to stop any leaks and secure the nails in place.
Flashing is the thin aluminum sheet metal that is used on roof edges and around abutments (such as chimneys) to keep rain from leaking or blowing into your home.
Strong winds and heavy rains can cause flashing to come loose. You must nail loose flashing in place and seal the outer edges. Use silicone sealant for areas that are visible from the ground, such as the sides of chimneys, and roofing cement where flashing is nailed into the surface of the roof.
You should also look for missing or broken roof tiles, and replace them as necessary. If all of your roof tiles look faded and worn, or you notice an abundance of asphalt granules in your rain gutters, it may be only a matter of time before your single leak becomes multiple leaks.
A roof repair service company may be needed for a larger undertaking, such as tearing off and replacing roof tiles. Bundles of roof tiles are heavy, and replacing tiles is dangerous work. Cleanup and disposal of the old tiles is also not much fun.
As with any unpleasant, dangerous, or dirty job, its always best to leave it to a professional like one from Weather Proofing Experts.
