However, roofing is also a significant investment, and like any major purchase, you want assurance that your roof will stand the test of time. This is where roofing guarantees come in. A robust guarantee not only covers defects in materials and workmanship but also provides protection against unforeseen issues down the road.

In the case of durable materials like Welsh slate can last for centuries. You can look at old roofs where the slate itself remains intact—it's often the fixings, like copper, that need replacing after around 100 years. Good-quality, second-hand Welsh slate can also last up to 100 years, which makes it unmatched in longevity. Welsh slate is a harder, denser stone due to its Cambrian geological properties, further adding to its strength and lifespan. which can last for centuries. Homeowners may expect this kind of quality from all roofing materials, however, it's important to understand that guarantees and warranties can vary widely depending on the material, installation quality, and the company providing them. Let’s break down the types of roofing guarantees available and what you should look for.

Types of Roofing Guarantees

There are typically two main types of roofing guarantees: Material Warranties and Workmanship Guarantees.

Material Warranties

Material warranties typically cover defects like premature cracking, splitting, or failure due to manufacturing errors. However, it’s important to note that the coverage provided by the company might be limited by the warranty terms of their supplier, meaning the roofing provider’s liability is only as good as the manufacturer’s warranty behind the materials. The slate meets the requirements of BS EN 12326-1:2004 should have imposed common European requirements that are understandable to suppliers and specifiers. 

These warranties guarantee the quality and longevity of their products. For example, as previously mentioned, high-quality Welsh slate can have warranties extending up to 100 years, as the material is incredibly durable and has been used for centuries with proven results. On the other hand, Spanish slate is geologically younger, around 200 million years younger than Welsh slate, which was formed around 400 million years ago. Although there is some confusion in the marketplace, a good-quality Spanish slate should last in excess of 50 years. Spanish slate only became widely available in the 1980s, which makes it newer to the market. Some sellers use aggressive sales techniques, so it’s important not to get confused by misleading claims. Look for high-quality Spanish slate that you can see examples of this, that date back as far as possible, and do your due diligence as not all Spanish slates are the same.

Workmanship Guarantees

This warranty is provided by the roofing contractor or installer. It covers the quality of the installation and ensures that any issues caused by poor workmanship, such as improper flashing or faulty installation techniques, will be repaired at no cost. Workmanship guarantees usually last between 5 to 10 years but can extend longer with reputable contractors.

Keep in mind that some roofing companies may not directly handle the installation themselves. If the company acts as a wholesaler or supplier, they may not offer an installation guarantee. In such cases, you should ensure that your contractor provides a separate workmanship warranty.

What Material Warranties Typically Cover

While coverage can vary, roofing warranties typically cover:

  • Structurally 
  • Colour Warranties: some man-made product could have colour guarantees fibre cement slates that ensures that

However, roofing guarantees do not usually cover:

  • Storm or Weather Damage: Most warranties won’t cover damage caused by extreme weather conditions such as hurricanes, hailstorms, or tornadoes.
  • Poor Maintenance: A warranty may become void if the homeowner neglects regular roof maintenance.
  • Third-party Interference: If a different contractor or individual repairs or alters the roof, it could nullify the warranty.

What to Look for in a Roofing Guarantee

When reviewing roofing guarantees, it’s important to consider the following:

Company Reputation and Stability

A warranty is only as strong as the company offering it. Ensure that the manufacturer or contractor you’re buying from is financially stable and has a solid reputation in the industry. Are they likely to be around 20-30 years time when issues may arise.  It's essential to research who you're buying from—are they qualified, and is their guarantee reliable? Many warranties can be worthless if the company isn’t financially strong or if they cease to operate. The supplier's strength is crucial, as your contract depends on the company’s ability to uphold the guarantee.

Wording of the Guarantee

Be wary of flashy promises and long guarantees that sound too good to be true. Pay attention to the fine print and legal definitions. Certain roofing guarantees may have exclusions or limitations that can void the warranty under specific conditions, such as if the roof is not maintained properly. For instance, many warranties exclude indirect losses, such as labor costs or scaffold hire, so homeowners may still have out-of-pocket expenses in the event of a defect.

Exclusions

Every warranty will have certain exclusions. Make sure you understand what is not covered, such as damage caused by external factors like storms or improper maintenance. Additionally, roofing products like natural slate can have slight variations in colour and dimensions, which are generally not considered defects.

Fit for Purpose

Some warranties include a "fit for purpose" clause, which means the roofing material is only considered defective if it fails to perform its basic function—like keeping the roof watertight. Natural materials like slate may vary in color or texture due to environmental exposure, and such variations are typically not covered under the warranty. Make sure to verify what the "fit for purpose" clause entails in your warranty.
