Plastic and old metal fittings often leak and many down pipes drain to the soil or paved areas potentially causing dampness and even structural problems. Defective gutters and down pipes. Trowel the roofing tar into the leak on the underside of the roof deck using a putty knife. It is best to have one down pipe for the front roof and two for the rear roofs.

If shingles get lifted or torn from high winds the damaged shingle exposes nails holding the shingle below it. And just one rusted out nail can cause your roof to leak every time it rains. Review the active leak and note the surface where the leak is dripping from. The absence or inadequate waterproofing in this areas can lead to variety of problem like leakages in ceilings below terrace floor dampness in parapet walls or seepage in the terrace slab.

Thus it is important to avoid cracks in slab in first place and waterproof it to prevent from these problems from occurring in future. Roof nail leaks can happen when roof nails have been loosened slightly from high winds or have simply pulled out over time. Push the shingle or plywood into the tar and trowel more roofing tar around the edges of the patch. If you have a lean to extension that the water from main roof on your house is discharged onto there is a significant chance of this roof leaking.
