Why Hire The London Roofing Specialists At The Ratio

If you are in need of roofing repair or replacement, or undertaking an extension project requiring new roofing, let our in-house experts advise you on the technicalities, logistics and process of your new roof.

Roof Repairs

Sprung a leak? Damp patches? Draught? Gutter leaking?

Here at the Ratio, we have 20+ years experience undertaking roofing installations and repairs in London. Our expert team can assess your roof, and requirement for repair or replacement. We can identify underlying and existing problems and anticipate further damage.

Some issues cannot be identified from the ground, so our experts are equipped with the necessary safety equipment and training to inspect your roof directly. 

Common roofing Mistakes

An incorrectly or poorly constructed roof can cause you and your family a lifetime of expensive repairs, damage and inconvenience.

We Only Use the Highest Calibre Materials

One of the most common roofing mistakes comes from using mismatched shingles, when contractors have purchased supplies from multiple suppliers. Not only is this unsightly, but could lead to water penetration and long-term damage. 

Here at The Ratio, we consistently use tried and tested supply distributors. During your initial consultation, we will show you the exact materials that will be used for your build, and we will never compromise on quality.

Insulation and Energy Efficiency

With London’s increasing utility prices, now is a better time than ever to become conscious of your home’s energy efficiency. 

Many London homeowners are also unaware of how inefficient attic ventilation may be in their properties. Even with correct insulation, poor ventilation will lead to moisture build up and destroy insulation materials. Our expert team will therefore consider your insulation and ventilation to provide you with the best return on your roofing investment, and long-term satisfaction with the results.

Not Every Roof is Built Equal

When considering new versus older builds in London, the slope and design of roofs in London properties varies greatly. This may be dictated by your personal preference, or local authority, as some parts of London implement restrictions on roof design and material. Importantly, you need to select a material that suits the shape of your roof, or your roof will be structurally unsound and vulnerable to water penetration. 

Our expertise working throughout the London area allows us to best advise you on the suitability of roofing materials and designs for your property, whilst considering your needs both aesthetically and economically.

We have experience in flat roof extensions, pitched roofs, and inverted pitched roofs- so trust us to help you get your roof right, the first time.

London Roofing FAQs

The cost of a new roof can vary greatly depending on the size of the roof, the type of material used, and any additional features or details. On average, a new roof can cost anywhere from £5,000 to £20,000 or more.

The lifespan of a new roof depends on the type of material used. Asphalt shingle roofs typically last 20-30 years, while metal roofs can last 50 years or more. However, proper maintenance and repairs can extend the life of any roof.

In most cases, planning permission is not required for a new roof as long as the work is not visible from the public highway and is in keeping with the overall appearance of the property. However, it is always best to check with your local council to be sure.

Installing a new roof can be a complex and dangerous job, and it is not recommended for homeowners to attempt it themselves. It is best to hire a professional roofing company with experienced and trained workers to ensure the job is done safely and correctly.

There are several signs that your roof may need to be replaced, including visible damage, leaks, and age. If your roof is over 20 years old and showing signs of wear, it may be time to consider a replacement.

We can can assess the condition of your roof and make recommendations for repair or replacement.

In some cases, it may be more cost-effective to repair your roof rather than replace it. However, if the damage is extensive or the roof is old and nearing the end of its lifespan, it may be more cost-effective to replace the roof. Get in touch so we can arrange an appointment where we assess the condition of your roof and recommend the best course of action.
