How to Fix a Leaky Roof?

When it comes to fixing a roof leak, you have to be very careful. Take a look below to see how you can work your way through the project. Just make sure to proceed with as much caution as you can manage. The smallest misstep can cause a mess. Moreover, before you start, make sure to have someone nearby to help out and that you’re hooked on to a personal fall arrest system (PFAS) to avoid accidents.

1. Find the Leak

In order to fix the leak, you need to be able to locate it. Climb up on the roof or visit your attic to scope out the damage.

2. Check the Roofing Vent

Often, the issue lies within the vent. To make sure the vents have not become dislodged, thoroughly inspect the area. If the leak is in the vent, carefully remove the part before replacing it with a new one.

3. Remove Old Shingles

If the problem persists and it is not due to the vents, check out your roofing deck by slowly removing the shingles and cutting out the underlayment.

4. Mark the Affected Area with Chalk

Once the space is bare, trace the shape of the damaged area with chalk, making sure to keep it along the center of the rafters.

5. Cut and Remove the Damaged Area

After marking the problem area of the deck, the next step is to slowly cut it out with the help of a circular saw blade. Set the blade’s depth to the roofing deck’s total thickness, and then add another 1/16 inch to it.

6. Craft a New Patch of Roof Deck

Use the previously cut roof deck as a template to trace out a new patch. For better precision and control, complete this step on the ground.

7. Attach the Deck with Underlayment

Once the new roof deck patch is prepared, nail it into the rafter beams until it is fixed in position. For protection, cover the patch with a layer of roofing paper or underlayment.

8. Finish it off with Shingles

Lastly, replace the old shingles with new ones by squeezing them all into place, making sure they are set in order.
