How to seal a roof leak

Asphalt shingles are made to be durable and weather-resistant, but problems with them can still occur. A leaking roof can be caused by numerous factors such as cracked, displaced or missing shingles, as well as damaged caulking or flashing.

If a shingle is cracked, you can conduct a temporary fix by applying a layer of roofing cement to seal the cracks. Similarly, if you need to fix flashing, you should use a caulk gun filled with a roofing cement to reseal the joints. Damaged joints that have been previously sealed will require a fresh new coat. Bear in mind that this can be only a temporary solution.

However, if you have missing or damaged asphalt shingles, you will need to replace them. Here is how to seal roof leaks easily:

  1. Use a pry bar to remove the nails, then slide the old shingle out.
  2. Scrape away any cement residue and level or remove protruding nails.
  3. Round the back corners of the new shingle with a utility knife and slide it under the one above, aligning it with the others on the same row.
  4. Secure the shingle by pinning a roofing nail in each of its corners.
  5. Apply a coat of roofing cement over the nails.

How to fix a leaking roof from inside

If you are looking for a way to temporarily fix your roof leak without having to actually go up on the roof, look no further. We’ve got you covered! While some leaking roofs require a skilled roofer, it is possible to temporarily patch them until you can invest in a professional repair. In this section, we will show you how to fix roof leaks from inside the attic using DIY temporary methods.

Before you begin work, make sure that the leaking point is dry. This will help you see the damage better and allow the roof patch to stick nicely.

  1. Use a putty knife to spread roofing tar over the leaking point from the inside.
  2. Press a piece of shingle or plywood onto the freshly applied tar.
  3. Spread some more tar around the edges of the patched area.
  4. Once the roof patch has dried, surround it with caulking, ensuring it is evenly spread.

Use marking chalk to draw a circle around the leaking point. This will work as your guideline for the patching process.

This is not a permanent solution! However, it is a way to patch things up until the weather is suitable for a repair job.

How to repair flat roof leaks

Flat roofs are inexpensive and easy to maintain, but also prone to sun and rain damage. Sometimes problems are left unnoticed until it is too late, so it is important to watch out for signs like water pooling, cracks in the roof or seams, presence of mould and moss, as well as moisture and leaks inside the property.

As tempting as procrastinating flat roof leak repair may sound, this is not something that should be put off for long. While a leaking flat roof may be a cause of concern, solutions still exist. With a couple of tools and materials in hand and some time to spare, you will be able to handle the repair yourself until you can call in a roof repair company.

If you are looking for a temporary solution for your leaking roof, here are a few simple steps on how to repair flat roof leaks:

  1. Inspect your roof and ceiling. Sometimes the leak inside may not be coming from the same spot as the water pooling on the roof.
  2. Clean and dry the roof. If water gets trapped underneath the patch while you are repairing it, it can cause mould growth.
  3. Identify the damage. Cracks are often caused by long hours of sun exposure, while blisters are a sign of water or air inside the roof layers.
  4. Get rid of the damaged area. If blisters are present, gently cut away the damaged layers of the roof membrane.
  5. Spread roofing cement over the damaged area. This will serve as a sealing material and adhesive for the membrane flaps.
  6. Lay down the membrane flaps and nail them to the roof. Cover the nails with more cement.
