Sure Choice Roofing

Expert Flat Roofing Specialists in Manchester & Cheshire

Modern, Seamless, and Maintenance-Free Solutions. Your New Flat Roof Comes Installed With An Insurance Backed Guarantee.

A Modern Approach to Flat Roofing

Historically, flat roofs had a poor reputation in the UK due to
old-fashioned felt and bitumen systems that would crack, blister, and leak after just a few years of North West rain. At Sure Choice Roofing, we have moved away from these outdated methods.


We specialise in high-performance GRP (Glass Reinforced Plastic) and EPDM (Ethylene Propylene Diene Monomer) systems. These modern materials are designed to be seamless, incredibly durable, and—most importantly—completely watertight. Whether you are replacing an aging
garage roof in Stockport or looking for a premium finish for a new kitchen extension in Wilmslow, we provide a professional, long-term solution that eliminates the stress of “flat roof failure.”

The Two Leaders in Flat Roofing: GRP vs. EPDM

During our initial assessment, we can advise on which system is best
for your specific project. Both offer world-class protection, but they
have different strengths:

1. GRP Fibreglass Roofing

GRP is the “Gold Standard” for aesthetic appeal and toughness. It is applied as a liquid resin over a glass-fibre mat, which then cures to form a single, solid, “monolithic” sheet.

2. EPDM Rubber Roofing

EPDM is a high-density synthetic rubber membrane that is incredibly flexible and durable. It is often installed in a single, large sheet, meaning very few (if any) seams.

Our Non-Intrusive Exterior Survey

We value your time and your privacy. To keep the process moving quickly, we conduct our technical surveys entirely from the exterior. Using high-resolution  hotography and our extensive on-site experience, we can assess the condition of your flat roof, identify drainage issues (pooling water), and check the integrity of the edge trims without ever needing to enter your home or climb into the loft.

This streamlined  pproach allows us to provide you with a fixed-price agreement quickly, so you know exactly what the investment will be before any work begins.

The Sure Choice Installation Process

We know that a leaking flat roof is often an urgent matter. Because we specialise in these specific systems, our installation process is fast and efficient. Most residential flat roofs (garages, porches, and extensions) are completed within our clients timelines.

1. Preparation: We remove the existing felt or failing material right back to the timber deck.
2. Deck Inspection: We check the timber boarding from the outside. If the boards are rotten from previous leaks, we replace them with high-quality OSB3 moisture-resistant decking.
3. Application: We apply the GRP or EPDM system using cold-applied methods—meaning no naked flames on your property, which is safer and better for insurance.
4. Detailing: We install professional-grade edge trims and wall flashings to ensure water is directed away from your masonry and into the gutters.
5. Final Quality Check: We ensure the “falls” are correct so that water doesn’t pool on the surface.

Your Insurance Backed Guarantee

We don’t just “patch and run.” We are a local business that takes pride in our craftsmanship. Every full flat roof replacement we carry out in Manchester and Cheshire comes with an Insurance Backed Guarantee.
This gives you total peace of mind that your home is protected.

If you have any questions or need a follow-up, our local team is always available to help.

Why Ventilation and Drainage are Critical

The two biggest enemies of a flat roof are standing water and condensation. In the North West, many old flat roofs fail because they were built “too flat,” allowing water to pool in the middle. During our installation:
● We Improve the “Fall”: If your old roof has pooling issues, we can install “tapered” firrings to ensure the water runs off correctly into your gutters.
● We Ensure reathability: We use modern materials that prevent moisture build-up in the roof timbers, which is a major cause of
structural rot in older extensions in Sale and Altrincham.

Local Expertise for North West Homeowners

We have successfully replaced flat roofs across the entire region. We understand the specific needs of local housing, from the converted
dormers in Chorlton to the large detached garages in Prestbury.

● Professional &  riendly: We are a team of local tradespeople who value clear communication and a job well done.

Frequently Asked Questions (FAQ)

Can you just put the new roof over the old one?

We strongly advise against “overlaying.” To give you an Insurance Backed Guarantee, we need to know the timber underneath is solid. We strip the roof back to the boards to ensure the foundation is perfect.

It depends on the roof’s use. If you need to walk on the roof or want a specific “architectural” look, GRP is usually best. For larger, simpler areas where flexibility and speed are key, EPDM is an excellent, cost-effective choice. We’ll help you decide during our survey.

Modern GRP and EPDM systems have a life expectancy of 30 to 50 years. They are significantly more durable than the old felt roofs of the past.

If you have an active leak, get in touch immediately. We work quickly to get our technical surveys completed so we can get your home watertight as soon as possible.
