Solution to roof leakage in houses - Silicone Sealant

The Best Roof Sealant for Mild to Moderate Roof Damage

Tracking down where a roof leak starts can be tricky, but it’s a must-do step. For small to medium issues—like redirecting water or filling small holes and cracks—a dependable roof sealant is your go-to solution. But if the damage is more severe, you’ll need a more thorough repair process.

First, figure out the exact spot of the leak inside your home. Remember: water might travel from another area, depending on your home’s structure. Once you have a rough idea of where the leak is coming from, check your attic. Look for dark stains or mold growth—these are clear signs of water seeping in. Next, inspect the matching part of your roof from the outside. On flat roof sections, watch for loose shingles, standing water, mold buildup, or rotting areas. The most common cause of roof leaks? Objects that poke through the roof, such as chimneys, roof vents, or any other fixture that goes straight through it.

For minor gaps and holes caused by these penetrating objects, Homey Premium Silicone makes repairs quick and easy.

Using Caulk for Roof Repairs

Once you’ve found the source of a small leak, you can seal it with roof caulk. For bigger repairs, you can use the sealant on new joints and materials as needed. Before applying the caulk, make sure the target joint is dry, clean, and free of debris—and that it’s structurally solid. Keep in mind: while sealant is flexible, it’s not meant to work as an adhesive.

Step-by-Step: Fixing a Roof Leak with Caulk

Gather your tools: Get a razorblade, gloves, a caulking gun, and the right sealant for the job.

Check for damage: Make sure the affected part of the roof is structurally sound and not rotting. If there’s rotted wood, replace it with new material before moving forward.

Locate the problem: Look for tears and cracks in the existing sealant—these are usually the main causes of roof leaks.

Clean the area well: Remove any old caulk, moisture, loose debris, asphalt, tar, paint, wax, or rust. Use a razorblade and acetone spray to get rid of the old compound effectively. Don’t forget to wear gloves to protect your hands.

Apply the sealant: Use the caulking gun with steady pressure to force the sealant into the joint. If needed, keep open products and tools out of direct sunlight for best results. For joints deeper than 13mm, use a backer rod along with the sealant. The sealant’s depth should be about half the width of the joint—max 13mm, min 6mm.
