Gutter Lining Systems
High performance roof gutter lining systems, a rainwater solution designed and built for maximum performance
Why Commercial And Industrial Gutters Fail
Your guttering is one of the most common failure points on commercial and industrial buildings. Joints open up as the metal expands and contracts through the seasons. And maintenance gets deferred until water is inside your building.
This results in water tracking through split seams and corroded sections, running down internal walls and reaching stock and floor space below. By the time a leak is visible inside your building, the gutter has been failing for a while.
Professionally installed gutter lining stops that. It results in a continuous, watertight surface inside the existing gutter, so water goes where it’s meant to.
Professionally Designed Gutter Systems Built For Purpose
Quite often gutters fail because they weren’t designed for the water volume they’re expected to manage.
A month’s rain in a few days is no longer rare in the UK. But many commercial and industrial rainwater schemes were sized for different expectations. They can’t discharge the volume they’re now facing. Lining a gutter that’s over capacity doesn’t stop an overflow.
That’s why we take a look at your entire rainwater scheme, not just the leak. Where existing outlets can’t cope we design additional rainwater outlets as part of the gutter lining works. You get a system sized for the rainfall your commercial roof actually experiences.
Seamless Gutter Lining System Solutions
A lining system is a continuous waterproof membrane fitted inside your existing gutter run. It’s shaped to the gutter, bonded in place, and sealed at every joint and outlet. The whole run becomes one unbroken surface.
This seamless lining is important because joints are where old gutters often fail, so a system that removes the joints removes the failure. You get a long-term watertight run, fully refurbished, without the cost and downtime of stripping out and replacing the original guttering.
Gutter lining vs full replacement
Replacing a commercial gutter run is a major job. You have to strip out the existing system, often taking down sections of roof edge, and disrupting your building while work is being done. For a working warehouse or factory, this downtime adds an additional cost.
Installing commercial gutter lining avoids this. Where your gutter’s structure is sound and the problem is failed joints or corrosion, a gutter lining system seals it in place. You can keep the existing run and avoid a strip out, meaning your building can stay open and undisturbed.
The commercial gutter systems we install
We match the right system to the condition of your gutter, the access and the lifespan you need out of it.
- Seamless lining membranes: A made-to-measure liner fitted and sealed inside the existing run, for gutters needing a full watertight refurbishment.
- Liquid-applied coatings and sealants: A lighter-touch option that seals joints and surfaces in place, suited to gutter problems caught earlier, before a full lining is needed.
What Working With Us Looks Like
From first enquiry to sign-off, the work runs in clear stages so you always know where you are during the project:
- 1. Free site survey: We inspect your gutter run, the outlets and the rainwater scheme, and assess whether lining is the right option or if replacement would be better.
- 2. Scope and quote: You get a fully scoped work plan with a transparent cost.
- 3. Preparation: Your gutter is cleaned and prepared so the system bonds to a sound surface.
- 4. Install and seal: The lining or coating is fitted, sealed at every joint and outlet, and additional outlets added where the scheme needs them.
- 5. Sign off: We check the finished run and sign of your watertight, refurbished gutter system.
