To DIY or Not to DIY: Your Guide to EPDM Rubber Roof Installation

If you’re considering installing an EPDM rubber roof, you may wonder whether to tackle the project yourself or hire a professional contractor. EPDM is a durable, cost-effective roofing solution, but is it a DIY-friendly option? Here’s a breakdown to help you decide.

Can You Install EPDM Roofing Yourself? 

EPDM roofing has become increasingly popular among homeowners due to its durability and cost-effectiveness for flat roof applications.

The process uses two specialised adhesives, a water-based adhesive and a contact adhesive, to ensure long-term durability and protection against leaks. 

EPDM can be easily installed by most competent DIYers, especially for small, straightforward flat roofs, like sheds, garages, and extensions. The process involves:

• Cleaning and preparing the surface

• Rolling out the EPDM membrane

• Applying adhesive

• Ensuring a smooth, wrinkle-free finish

• Sealing edges and joints with trims

Don't forget to include appropriate drain outlets when preparing your flat roof to promote adequate rainwater drainage.

With proper preparation and attention to detail, installing an EPDM rubber roof can be a manageable DIY project for those comfortable working at heights.

Many homeowners successfully install EPDM themselves using the manufacturer’s instructions and online guides.

Pros of DIY EPDM Installation:

Working with EPDM rubber gives you valuable insights into your roofing system's maintenance needs and potential issues.

EPDM roofing membrane is lightweight, flexible, and designed for simple installation compared to other materials.

• Cost savings – Avoid labour costs by doing the work yourself.

• Hands-on experience – Gain knowledge of your roof for future maintenance.

• Flexible timing – Work at your own pace without the contractor’s schedules.

DIYers can purchase EPDM rubber roof kits, which include the essential membrane, adhesive, sealants, and trims for straightforward installation on flat roofs.

Cons of DIY EPDM Installation:

• Skill and knowledge required – Proper installation is crucial to avoid leaks and poor adhesion.

• Mistakes can be costly – Errors may lead to repairs or premature failure.

• Physical effort and time – Installation requires lifting, positioning, and working with adhesives.

When to Hire a Professional Contractor:

While EPDM roofing is DIY-friendly, certain situations require professional expertise to ensure optimal performance and longevity.

Hiring a contractor is often the best choice for larger or more complex projects. Consider professional installation if:

• The roof is large or has multiple obstacles (vents, skylights, chimneys)

• You’re unfamiliar with roofing techniques

• The project involves removing old roofing material

• You want long-term peace of mind with a warranty-backed installation

Pros of Hiring a Contractor:

• Expert installation – Reduces the risk of leaks and poor adhesion.

• Professional installers - They have extensive experience with EPDM rubber roof systems and understand the nuances that ensure watertight seals and proper drainage.

• Time-efficient – A professional can complete the job faster than a DIY approach.

• Warranty coverage – Many professionals offer guarantees on their workmanship. In addition, certified installers who have completed the Rubber4roofs training course can provide a 20-year warranty on the membrane along with their own workmanship guarantee.

• Proper tools and materials – Contractors have access to high-quality tools.

Cons of Hiring a Contractor:

• Higher cost – Labour charges can significantly increase the overall price compared to DIY.

• Scheduling dependency – You’ll need to work around the contractor’s availability, which may delay your project.

• Less personal involvement – You don’t gain the same first-hand knowledge of your roof for future maintenance.

• Quality can vary – Not all contractors specialise in EPDM; hiring the wrong one may lead to issues despite paying more.

Final Verdict: DIY or Professional?

EPDM rubber roofing suits DIY enthusiasts tackling small-scale projects with basic practical skills. However, hiring a contractor is safer for larger or more complex roofs to ensure quality and reliability. When installed correctly, EPDM roofing membranes can last up to 50 years, offering reliable protection for decades. To help complete your project, search for a rubber roof membrane or kit with Rubber4roofs.

Professional installation ensures a flawless, long-lasting result, while DIY offers cost savings and hands-on experience for simpler jobs. Assess your knowledge, time, and budget to choose the best approach for your needs.
