A leaking roof, particularly in the winter, is no laughing matter. Besides the immediate damage to ceilings, furniture and floors, water has a way of creating its own path. What might start as the odd drip one night, can soon become a dribble and before you know it, a dribble can spring open to become a hole. For this reason, no household should be without emergency tubes of silicone sealants.
So what’s the most effective way to use sealants when trying to repair a leak?
Waterproofing Leaks in Shingles and Slate
If you can safely access your roof, your first task should be to look for visible cracked, loose, missing or curled back shingles or slates. Taking care of this is one way to divert water back down towards the drains and this may be enough to stem the leak. However, if all seems to be in order you can examine the nails holding the shingles in place. Rusty nails or nails blown bent from storm winds, create pores through which water can travel.
At some point, preferably not during the storm season, these nails should be removed and replaced to ensure a close fitting connection between the shingle and the roof. But in the meantime, a good silicone sealant can be used to cap the nail head and create a waterproof barrier. Simply apply the sealant and spread downwards. In the spring or summer, when you come to repair the roof, a sealant remover can be used to dissolve the bonds.
Taking Care of Felt Roof Leaks
However, if you have a felt or similar sheet roofing, your inspection will have to be more thorough. In felt, blisters can lead to hairline cracks or fissures but remember, water runs with gravity along surfaces. This means that a leak presenting in one room may be the result of a problem further along the roof in a slightly elevated position.
While these faults will eventually need treating, you can prevent further damage by applying a silicon sealant, available from many sites like ct1ltd and others over the damaged area. Again, the sealant should be applied and spread downwards over, or along the crack or tear.
These are by no means long term solutions, but used quickly, a good silicone sealant can save you a fortune in damage.
