How to Repair Granular Loss on Roof

The roof is the first line of defense for any home, protecting it from the elements. Over time, roofs may develop issues, such as granular loss, which can compromise their integrity and lead to costly repairs if not addressed promptly. Granular loss occurs when the protective granules on the shingles begin to wear off, leaving the asphalt exposed to the sun’s harmful UV rays. If you notice granular loss on your roof, it is crucial to take immediate action to repair it. Here are some steps to help you repair granular loss on your roof:

1. Inspect the roof: Begin by thoroughly inspecting the roof for areas with granular loss. Look for spots where the shingles appear discolored or have bare patches without granules.

2. Gather the necessary tools: To repair granular loss, you will need a ladder, a roofing hammer, roofing nails, a tube of roofing cement, and replacement shingles.

3. Secure loose shingles: If you come across any loose or lifted shingles during the inspection, use roofing nails to secure them back in place. Be careful not to hammer the nails too hard, as it can damage the shingles further.

4. Apply roofing cement: Use a roofing cement and a putty knife to apply a thin layer of cement on the exposed areas where the granules have worn off. Ensure that the cement covers the entire area and acts as a protective barrier.

5. Replace damaged shingles: If you find shingles with extensive granular loss or damage, it is best to replace them. Carefully remove the damaged shingles using a roofing hammer and replace them with new ones. Align the new shingles with the existing ones, ensuring a seamless appearance.

6. Seal the edges: To prevent future granular loss, apply a small bead of roofing cement along the edges of the new shingles. This will provide an extra layer of protection against wind and water damage.

7. Clean up: Once you have completed the repairs, make sure to clean up any debris or loose granules that may have fallen onto the roof or into the gutters. This will help maintain the longevity of your roof and prevent clogged gutters.
