Locating a roof leaking requires honing specific detection skills to pinpoint the exact cause and location of the issue, whether it originates from the outside or inside your home. Roof leak detection is difficult.

Steps to look for roof leak

1. Roof Scrutinization

Roof scrutinization is the first step to looking for signs of roof leakage outside or inside the house. Try figuring out both the explicit and vague indications that pinpoint the leakage sites, which may include:

  • Water stains on the walls or ceilings
  • Flaky paint due to moisture build-up
  • Musty smells or mouldy odours
  • Distorted or missing roof shingles
  • Water-damaged exterior siding
  • Bulging sections on the walls

2. Prevent Internal Walls Leakage

After inspecting the signs of leakage in the roof of your home, it is essential to look for and then rule out the probable water leaking that might be damaging the walls or ceilings. Regular assessment of water pipes can prevent internal wall leakage. In addition, be mindful to check those rooms or areas of your house where water usage is necessary, for example, kitchens, bathrooms, and laundry areas.

3. Detailed Attic Examination

The attic is the place that lies just beneath the roof of your house. While checking roof leakage and learning how to fix a leaking roof from the inside, it is crucial to thoroughly examine if the attic ventilation is being damaged by continuous water dripping. The most common pointers to check for leaky roofs are the presence of musty or mouldy odours and the bulging of smaller sections due to moisture build-up in the walls around the rafters and roof decking. Carry a flashlight to check the congested and hard-to-see areas of your house.

4. Inspection of Roof Surface

Grab a ladder and start examining all the vents, chimneys, skylights, and roof seams, and check for any signs of water collection that might damage the ceilings and walls. Look out for loose or damaged shingles and distorted or missing nails that were holding the roof panels together in place. Besides, the moisture might be locked in the area where leaves have been falling and being collected as debris.

The basic technique to fix an exterior and internal leaky roof is more or less the same; the only difference is if there’s an emergency to fix roof leak or the damage is severe enough to seek experts’ advice for roof repair or replacement.

Redirect the Water Flow

You may not be able to seal the leakage right away, especially when it is continuously raining outside, and in such cases, temporary patches won’t help. That’s why it becomes necessary to divert the direction of flowing water.

The most basic approach to divert water is to firmly embed a nail into the ground, encouraging the water to funnel in a new direction. Based on the speed of the diverted flow, decide the ideal location to install a gallon for collecting water. Make sure the capacity of the bucket is enough to collect the water so the excess dries out or evaporates in the air.

Sealant Application

After finding the roof leakage and diverting its flow, it is to ensure the area is arid as dust. Using chalk, you can mark the area in case you forget, or it dries out too much to be noticed again. In case of any moisture, the sealants would be of no help. When the interior roof is dried out, apply a liberal amount of roof patch on the target site and spread it evenly with the help of a scraper till the area is entirely covered. Once the place is completely dry, use caulking materials to seal the holes or cracks that may appear afterwards.
