Commercial Roof Soundproofing


Commercial buildings often deal with a wide range of noise sources, from HVAC systems to nearby traffic and industrial activities. We focus on installing heavy-duty acoustic panels and mass-loaded vinyl (MLV), which are proven materials for blocking airborne noise.


Our approach includes evaluating the building's structure to integrate resilient channels and soundproofing clips. These create isolation layers that minimize vibration transmission through the roof framework. Sound attenuation systems are designed to fit large-scale roofing surfaces without compromising durability or fire safety standards.


We also offer consultation on roof material choices to balance noise reduction with commercial roofing requirements like weather resistance and energy efficiency.

Residential Roof Soundproofing


Homeowners face noise from traffic, neighbors, and environmental sources. We focus on lightweight but effective solutions, such as adding high-density insulation like fiberglass or mineral wool in attics or under roof decks.


Acoustic panels may be installed inside ceilings for additional sound absorption. For eco-conscious clients, we recommend green roofs when structurally feasible, using low-maintenance plants that naturally reduce noise.


Our residential service includes decoupling techniques, such as resilient channels, to prevent sound vibrations from penetrating living spaces. These options are customized based on the home's roof structure and the occupant’s noise reduction goals.

Existing Roof Upgrades and Retrofits


Retrofitting an existing roof requires careful assessment to identify weak points where sound leaks through. We start with a thorough inspection and sound level testing to target problem areas accurately.


Solutions include adding mass-loaded vinyl layers beneath roofing materials, installing acoustic insulation in attics, and implementing decoupling methods like soundproofing clips. Additional drywall layers can be applied inside ceilings along with vibration isolation pads for impact noise control.


We specialize in upgrades that maximize soundproofing without major structural changes, allowing clients to improve noise control while keeping project costs and timescales reasonable.

New Roof Construction for Soundproofing


When building new roofs, we integrate soundproofing at the design stage. We use multi-layered roofing assemblies that combine dense, sound-blocking materials like MLV with high-quality insulation and resilient channels to isolate noise.


Our team recommends soundproof membranes and roofing underlayments selected specifically for acoustic performance. We also design proper ventilation and drainage to prevent moisture issues that can affect soundproofing integrity long-term.


This proactive approach ensures the roof delivers lasting noise reduction and enhances occupant comfort from day one. Coordination with architects and builders is key to achieving these integrated soundproofing goals.

Materials and Techniques for Effective Roof Soundproofing

Soundproofing a roof requires using materials and methods that both block and absorb noise effectively. Combining dense barriers with specialized insulation and absorption materials helps reduce sound transmission. Proper installation techniques also play a critical role in minimizing vibrations and preventing sound from traveling through the roof structure.

Insulation and Attic Solutions


We prioritize high-quality thermal and acoustic insulation to reduce sound entering through the roof. Dense materials like fiberglass insulation and mineral wool absorb sound waves and reduce echo within the attic space.


Spray foam insulation offers both an air seal and sound dampening, filling gaps that allow noise penetration. Adding layers of attic insulation beneath the roof decking or in joist spaces significantly cuts down sound transfer.






High-Mass Barriers and Underlayment


Mass plays a key role in blocking sound transmission. We install mass-loaded vinyl (MLV) as an underlayment beneath roof materials like plywood or oriented strand board (OSB). MLV is a dense, flexible sound barrier that reduces airborne noise.


Additional mass can be created by layering materials, such as adding extra drywall or plywood with decoupling methods like resilient channels and sound isolation clips. These create separation between surfaces to prevent vibration transmission.



Acoustic Panels and Sound Absorption


To further reduce noise, we install acoustic panels or foam panels inside attic or ceiling spaces. These materials absorb mid to high-frequency sound waves, reducing reverberation.


Options include fabric-wrapped acoustic panels, acoustic foam, or mineral wool boards, depending on the setting and aesthetic preferences. Panels slow sound reflections and improve overall quietness.

Frequently Asked Questions About Roof Soundproofing

  • How much does roof soundproofing cost?

    Roof soundproofing typically costs $2,500-$7,000 for homes depending on square footage, existing construction, and desired noise reduction. Basic acoustic underlayment starts at $2,500, while comprehensive systems with mass-loaded vinyl and resilient channels reach $7,000-$10,000. Commercial applications run $4-$8 per square foot. Thousand Oaks Superior Roofing offers tiered packages with different STC ratings to match specific needs and budgets.


  • Does roof soundproofing really work?

    Yes, professional roof soundproofing reduces noise transmission by 25-40 decibels when properly installed. Most customers report 70-85% reduction in aircraft, rain, and traffic noise. Modern acoustic systems like QuietRock and Roxul Safe'n'Sound create multiple density barriers that absorb different frequencies. Our installation techniques target specific neighborhood noise patterns for optimal results.


  • What are the best materials for soundproofing a roof?

    Effective roof soundproofing combines mass-loaded vinyl for density, acoustic mineral wool for absorption, resilient channels for decoupling, and acoustic sealants for gap elimination. Green Glue damping compound reduces vibration between layers. For vaulted ceilings, SoundBreak XP drywall works well with blown-in cellulose insulation. Products from Kinetics Noise Control and Acoustiblok deliver excellent performance while maintaining energy efficiency.

  • How do I reduce noise coming through my roof?

    We first assess your current roof construction and identify specific noise issues. Our technicians then install multi-layer systems including blown-in dense insulation, mass-loaded vinyl barriers, and acoustic ceiling treatments. We seal ventilation outlets, chimney gaps, and other penetration points to prevent sound leakage. Complementary attic treatments and integration with existing insulation ensure comprehensive noise protection.
