A system for every stage of a metal roof. From a single rusting lap to a full roof coating.

The four liquid-applied systems are developed and supplied by Allbase, and the survey decides which one a roof gets. Two seal and reinforce the cuts where the sheets are still sound. Two are sprayed across whole roofs when the factory coating has had its day. All four are certified, installed by expert contractors and guaranteed.

A quick roof assessment. Five questions, an indicative grade, and what it would take to put right.

Cut edge corrosion goes through three stages, and which one a roof is at decides whether it needs a repair at the cuts or a whole roof coating. Answer five questions and you will have a rough idea before anyone visits.

Question 1 of 5

How old is the roof?

New to the problem? What is cut edge corrosion?

The proof is on the roof. Recent work by the expert contractor network.

What happens next. The four stages from first contact to guarantee.

  1. Survey and condition report

    A local surveyor inspects the roof and writes it up with the roof's condition and the options.

  2. Proposal and fixed quote

    The recommended works, the system, the cost and the timescale, in writing. No obligation.

  3. Repair

    An expert contractor installs to the specification, around a live site, and the work is inspected on completion.

  4. Guarantee and maintenance

    Basecare cover and the completion records, with a maintenance cycle that keeps the guarantee in place.

Surveys and treatments near you. Wherever the roof is, there is a surveyor and an expert contractor who covers it.

Cut edge corrosion moves faster on some roofs than others: salt air on the coast, sulphur and grit around heavy industry, and sheltered inland sites slowest of all. Every area below has a page of its own with the towns, postcode districts and estates it covers, and what a roof there tends to face.
