How To Fix A Leaking Roof From The Outside
In this section, we shall learn about the processes of leak repairing of the roof from the outside. Though it can also be done from inside of the house. But, we shall focus on doing it from the outside for the following reasons:
- Easy to find the leak
- Easy to repair

- The reason for the leak can be known
- No damage to the inner, insulators, or the interior furniture of the house
- Damages of the gaskets, pipes.
Now we are discussing the method for fixing the leaking roof from outside:
1. Notice the Position of the Leak
Now, there can be two types of leak positions in your roof. The first type should have a direct connection with the roof leak and the point of the drippings. On the other hand, there can be a leak on your roof which finishes into a secondary point internally to cause the actual leakage. It is important to inspect and find out the exact source of leaks.
Leak fixation should be done in bright daylight. You can climb up to the attic and manually search for the leaking following the path of the dripping.
Normally, visual inspection is enough to find the leak. But during dry weather the watermarks, stains on the ceiling, or sheathing are not possible to be found. Now, in such cases, you can use the water test with the help of your family members or friends. Use the water spray on the entire roof and check for the space where the drippings are found.
You must check for the coincide point of the outdoor leakage on the roof and inner leakage from inside the house. If the two points of inner and outer leakage merge then it must be the actual point of leakage. Again, considering the inner and outer point of leakage doesn’t merge Then there must be an actual point of leakage on the roof that needs fixing from outside.
And, there should be an apparent and different position of leakage which causes the dripping. It can also be fixed from the outside. In such cases, the water travels from the defective sheathing to rafters and finally comes to the ceilings. The path can be observed to find out the exact leak posing on the roof.
2. Get The Required Fixing Tools
After you have successfully found the presence of the leak, you must get the tools or repair kits to fix it permanently. For example, curled-up shingles cause major leaks in extreme weather-based towns. Poor coating and nailing can lead the upper shingles to get loosened with time and shift from their specific patterned places.
In general, asphalt roofing cement, rubberized patch for the leak, roofing nailer and nail, caulk gun, and utility knife.
3. Fixing the Rolled-up or Ruptured Shingles
These shingles are formed due to poor coating using the cement and nailing as well. Besides, storms or tornadoes can also cause such types of problems. You can simply put some roofing cement through the caulk gun to put the shingle back in place. Besides, for additional safety use the roofing nailer to shoot through the shingles to firmly stick them in the place.
4. Replacement of the Ruptured Shingles
Many times, the shingles get permanently damaged due to extreme impacts such as falling heavy objects through the storm. In such cases, the entire shingle must be replaced from the sheathing in the attic. You can use a utility knife and pry bar to pull off the nails along with the shingle. The residual cement should be completely removed.
Now, slide down the new piece of shingle in between the overlapping shingles. It can be done easily if you use the knife to round off the corners of the shingle. Finally, nail the shingles securely using a compatible roofing nailer and 2in of nails.
