Is It Loud During Rain or Storms?

No—modified bitumen roofing is not loud during rain or storms. Unlike metal roofing, which can amplify the sound of rainfall, modified bitumen’s multi-ply asphalt and reinforcement layers absorb impact and dampen noise. At L&L Roofing & Construction, we often hear homeowners are surprised at how quiet these systems really are.

Why Modified Bitumen Is Quiet

  • Multi-Layer Construction: Asphalt and polymer plies absorb sound from rain and hail.

  • Insulation Below: Most systems include insulation boards that further reduce noise.

  • Protective Cap Sheet: Granulated or coated top layers help deaden the impact of rain.

  • Seamless Waterproofing: Unlike loose panels, membranes are bonded in place, reducing vibration.

Compared to Other Roof Types

  • Quieter than Metal Roofing: No “drumming” effect during storms.

  • Similar to Shingles: Provides the same kind of muted sound homeowners expect.

  • Quieter Than Single Ply (in some cases): Multi-ply design absorbs more impact than thinner membranes.


FAQ: Is Modified Bitumen Roofing Loud During Rain or Storms?

Q: Will heavy rain sound loud inside?
A: Not usually. Most of the sound is absorbed by the layers and insulation.

Q: What about hail?
A: Small hail is muffled, but very large hail can be heard—though that’s true with any roof system.

Q: Can extra insulation make it quieter?
A: Yes. Adding more insulation not only improves energy efficiency but also reduces noise further.

Q: Is modified bitumen quieter than single ply systems?
A: Often, yes—because of its thicker, multi-ply design.
