Bitumen Roofing vs PVC Roofing Sheets: Which Is Better?

Bitumen Roofing vs PVC Roofing Sheets: Which Is Better?

Choosing the right roofing material for sheds, garages, workshops, and garden buildings often comes down to two popular options: corrugated bitumen roofing and PVC roofing sheets.

Both materials are widely used in the UK, but they perform differently depending on budget, environment, and how the building will be used. In this guide, we compare bitumen roofing vs PVC roofing sheets to help you choose the best solution for your project.


What Is Corrugated Bitumen Roofing?

Corrugated bitumen roof sheets are made from bitumen-saturated fibres, formed into a corrugated profile for added strength and water runoff.

They are commonly used for:

  • Garden sheds

  • Garages

  • Workshops

  • Stables and agricultural buildings

  • Storage units

What Are PVC Roofing Sheets?

PVC roofing sheets are lightweight plastic sheets, often translucent or clear, designed to allow natural light into a structure while providing weather protection.

PVC roofing is commonly used for:

  • Greenhouses

  • Carports

  • Canopies

  • Pergolas

  • Patio covers


Strength & Durability Comparison

Corrugated Bitumen Roofing

  • Strong and flexible

  • Handles wind and rain well

  • Quiet during heavy rainfall

  • Designed for long-term outdoor exposure

PVC Roofing Sheets

  • Lightweight but less impact-resistant

  • Can become brittle over time if low-quality

  • Noisy in heavy rain

  • More vulnerable to cracking under impact

Winner for durability: Corrugated bitumen roofing


Weather Resistance & Waterproofing

Bitumen Roofing

  • Excellent waterproofing

  • Performs well in UK wind and rain

  • Less affected by temperature changes

PVC Roofing

  • Waterproof when installed correctly

  • Can expand and contract significantly

  • Fixings must allow for movement

Winner for UK weather: Bitumen roofing


Light Transmission

Bitumen Roofing

  • Opaque

  • Blocks sunlight completely

  • Ideal where shade or storage is required

PVC Roofing

  • Clear or translucent options

  • Allows natural daylight

  • Ideal for greenhouses and covered seating

Winner for light: PVC roofing sheets


Noise Levels During Rain

One major difference between the two materials is noise.

  • Bitumen roofing absorbs sound and remains quiet

  • PVC roofing amplifies rain and hail noise

For garages, workshops, and sheds, bitumen roofing provides a more comfortable environment.


Installation & Ease of Use

Bitumen Roofing

  • Easy to cut and fix

  • Installed directly onto timber battens

  • Uses simple nails or fixings

  • Forgiving for DIY installers

PVC Roofing

  • Lightweight and easy to lift

  • Requires careful allowance for expansion

  • Fixings must not be overtightened

  • Can crack if installed incorrectly

Winner for DIY installation: Bitumen roofing


Cost Comparison

  • Bitumen roofing is typically more cost-effective

  • PVC roofing can be cheaper upfront but may require earlier replacement

  • Bitumen accessories are affordable and long-lasting

Over time, bitumen roofing often offers better overall value.


Lifespan & Maintenance

Bitumen Roofing

  • Lifespan: 10–20+ years

  • Minimal maintenance

  • Resistant to rot and corrosion

PVC Roofing

  • Lifespan varies by quality

  • Can discolour or become brittle

  • May need replacement sooner

Which Should You Choose?

Choose corrugated bitumen roofing if you need:

  • Durability

  • Quiet performance

  • Long-term value

  • Reliable weather resistance

Choose PVC roofing sheets if you need:

  • Natural light

  • Lightweight coverage

  • Greenhouse or patio use

For most sheds, garages, and workshops, bitumen roofing is the stronger, more practical option.
