How Moss Damages Shingles Over Time

On Millersville roofs, especially in shaded areas:

• Moss and algae embed themselves in shingle granules
• Moisture is held directly against the asphalt surface
• Granules loosen, and shingles become thinner and weaker
• Edges can curl or lift, letting water work underneath

Left alone, this process can force a full roof replacement years earlier than if the growth had been treated.

If you catch growth early and remove it properly, you can often get more life out of your existing roof and avoid a big replacement bill.
