Choosing the Right Flat Roof in London: Tips and Advice You Can Trust
When it comes to flat roofs, many homeowners in London feel uncertain—and rightly so. Poor materials and subpar workmanship have given flat roofing a bad reputation over the years. But the truth is, with the right team and quality installation, Flat Felt Roofing in London can be one of the most durable and cost-effective options for your property.
Take a quick look across the rooftops of Palmers Green or while travelling through the city, and you’ll see flat roofs everywhere. They’ve been part of London’s skyline for generations—and when done right, they perform exceptionally well.
We know that a professionally installed flat roof using high-end materials can last for decades. That’s why we use a three-layer Reinforced Bituminous Membrane system (also known as a felt roofing system), which is one of the most tried-and-tested solutions available. It’s known for:
-
Long life expectancy
-
Low maintenance requirements
-
Proven performance in harsh British weather
-
Cost efficiency and excellent waterproofing
When installed and maintained correctly, Flat Felt Roofing in London is not only reliable but a smart alternative to pitched roofing.
Top Tips for a Quality Flat Roof Installation
-
Choose a Trusted Contractor
Always select a roofing contractor who is trained and certified by the membrane manufacturer. Ask to see previous work and speak to past clients. Look for contractors registered with the NFRCor part of the Competent Roofer Scheme.
-
Use a Quality Membrane
The membrane is the core of your flat roof system. It must effectively channel water off the roof and into the guttering system. Opt for systems that come with a manufacturer’s warranty for peace of mind.
-
Ensure a Suitable Roof Deck
The deck forms the base of your flat roof. It needs to be strong enough to support expected loads and properly secured. If the deck is weak or poorly installed, your roof won’t perform as it should.
-
Design for Proper Drainage
Flat roofs should never be completely level. A slight slope (called a fall) helps surface water drain quickly. This can be achieved through tapered insulation or by adjusting support structures beneath the deck.
-
Meet Insulation and U-Value Standards
By law, both new and refurbished flat roofs must meet specific U-value targets for insulation. This is regulated by local Building Control authorities. Insulation is not optional—it’s a legal requirement when replacing your roof.
