Typical Roofing Installation Warranty: Conditions and Types

March 20, 2025
5 min read

A roofing installation warranty is a written guarantee provided by roofing contractors that protects homeowners against defects in workmanship during the roof installation process. This warranty specifically covers the labour and installation techniques used by the roofing company, not the materials themselves. At Adelaide Roofing & Construction, we offer comprehensive installation warranties to safeguard your investment in your roof.

The purpose of a roofing installation warranty is to give homeowners financial protection against future repairs that might be needed due to mistakes made during the installation. This warranty ensures that if problems arise because of improper installation techniques, we will fix these issues at no extra cost to you.

Roofing installation warranties are important because they provide peace of mind and security for homeowners. Your roof is one of the most significant investments in your home, and knowing that the workmanship is guaranteed helps you feel confident in your choice of contractor. These warranties show that we stand behind our work and are committed to quality craftsmanship.

A typical roofing installation warranty from Adelaide Roofing & Construction covers specific aspects of the installation process. This includes improper nail placement, incorrect flashing installation around chimneys and vents, poor sealing that allows water penetration, inadequate ventilation installation, and faulty gutter installation that affects drainage. Our warranties do not typically cover damage from severe weather events, normal wear and tear, or issues caused by homeowner modifications.

Roofing installation warranties come in several types. These include standard workmanship warranties (usually 2-5 years), extended workmanship warranties (10-25 years), transferable warranties that can be passed to new homeowners if you sell your property, and non-prorated warranties that maintain full coverage throughout the warranty period.

Finding a reputable roofing contractor in Adelaide that offers solid installation warranties is essential for long-term roof performance. Since our establishment in 2014, Adelaide Roofing & Construction has provided reliable roofing services with strong warranties that protect our customers. A quality contractor will explain warranty terms clearly, provide written documentation, be properly licensed and insured, and have positive reviews from past customers who have tested their warranty claims process.

What is Roofing Installation Warranty?

A roofing installation warranty is a contractor's promise to stand behind their workmanship for a specified period. Unlike manufacturer warranties that cover material defects, our installation warranty specifically addresses how well we installed your roof. This includes the techniques, methods, and processes we used during the installation.

The benefits of having a roofing installation warranty are numerous:

  • Financial protection against costly repairs that might be needed due to installation errors
  • Peace of mind knowing that your investment is protected for years to come
  • Quality assurance as contractors with strong warranties tend to do better work to avoid claims
  • Enhanced home value as warranties can often be transferred to new owners if you sell your home
  • Professional support with a dedicated team ready to address any concerns that might arise

What Does a Roofing Installation Warranty Cover?

A roofing installation warranty from Adelaide Roofing & Construction covers defects and issues directly related to the quality of our workmanship during the installation process. This warranty protects homeowners from having to pay for repairs that are needed because of installation errors rather than material failures or other causes.

Our roofing installation warranty typically covers:

  • Improper nail placement – Nails that are overdriven, underdriven, or incorrectly positioned can cause shingles or metal sheets to lift or come loose
  • Flashing installation errors – Incorrectly installed flashing around chimneys, skylights, vents, and valleys that may lead to water leaks
  • Improper sealing – Poor sealing techniques that allow water to penetrate beneath roofing materials
  • Ventilation issues – Incorrectly installed roof ventilation systems that can lead to moisture buildup in the attic and reduced roof lifespan
  • Faulty gutter installation – Improperly installed gutters and downpipes that don't channel water away from the home effectively
  • Alignment problems – Crooked or misaligned roofing materials that affect both appearance and functionality
  • Ridge capping defects – Poorly installed ridge caps that can allow water entry or come loose in high winds
  • Waterproofing failures – Issues with waterproofing membranes or barriers that were incorrectly applied during installation

What Is Not Covered in Roof Warranty?

While our roofing installation warranty is comprehensive for workmanship-related issues, there are certain conditions and situations that fall outside the scope of coverage. Understanding these exclusions is important for homeowners to maintain appropriate expectations about their warranty protection.

Our roofing installation warranty typically does not cover:

  • Storm damage – Damage caused by severe weather events such as hail, extreme winds, or falling tree limbs
  • Normal wear and tear – The natural deterioration of roofing materials that occurs over time with exposure to the elements
  • Homeowner modifications – Any changes, repairs, or alterations made to the roof by the homeowner or other contractors after installation
  • Lack of maintenance – Problems that develop because routine roof maintenance was neglected
  • Material defects – Failures in the roofing materials themselves (these are typically covered by the manufacturer's warranty instead)
  • Consequential damages – Damage to the home's interior, belongings, or other property that might result from a roof failure
  • Unauthorised repairs – Any repairs attempted by anyone other than Adelaide Roofing & Construction or our authorised representatives
  • Solar panel installation damage – Issues caused by the installation of solar panels or satellite dishes after the roof was completed
  • Pest damage – Damage caused by birds, rodents, insects, or other pests
  • Foot traffic damage – Problems resulting from excessive or inappropriate foot traffic on the roof

What Are the Roofing Installation Warranty Types?

Roofing warranties come in different forms to protect various aspects of your new roof. At Adelaide Roofing & Construction, we believe it's important for homeowners to understand the different types of warranties available so they can make informed decisions about their roofing investments.

The main types of roofing warranties include:

  • Standard Workmanship Warranties – These typically last 2-5 years and cover basic installation errors. We offer these as our entry-level warranty option.
  • Extended Workmanship Warranties – These provide longer coverage periods of 10-25 years and offer more comprehensive protection against installation defects. These are ideal for homeowners planning to stay in their property long-term.
  • Transferable Warranties – These warranties can be passed to new homeowners if you sell your property, which can increase your home's resale value and appeal to potential buyers.
  • Non-prorated Warranties – These warranties maintain full coverage throughout the entire warranty period without reducing benefits over time, unlike prorated warranties where coverage decreases as the roof ages.
  • Full System Warranties – These combine material and workmanship coverage into one comprehensive warranty when all roofing components come from the same manufacturer and are installed by a certified contractor.
  • Limited Lifetime Warranties – These typically cover materials for the lifetime of the original homeowner but may have specific limitations on labour and transferability.

Material Roofing Warranties

A material roofing warranty is a guarantee provided by the manufacturer that covers defects in the roofing materials themselves. This warranty is separate from the workmanship warranty that we provide as contractors. Material warranties protect against manufacturing defects that might cause the roofing products to fail prematurely.

Each roofing material brand has its own specific material warranty with different terms, conditions, and coverage periods. These warranties vary significantly depending on the manufacturer and product quality:

  • Colorbond® Steel – This popular Australian metal roofing product comes with up to a 30-year warranty against corrosion and material defects when installed according to manufacturer specifications.
  • Monier Roof Tiles – Monier offers warranties ranging from 25-50 years on their concrete and terracotta roof tiles, covering manufacturing defects and colour performance.
  • CSR Bradford – Their insulation and roofing products come with warranties ranging from 15-30 years, depending on the specific product line.
  • BRISTILE Roofing – Their La Escandella terracotta tiles come with a 100-year product warranty against defects in materials.
  • Lysaght – Their steel roofing products offer warranties ranging from 12-36 years against perforation by weathering and material defects.
  • BGC Fibre Cement – Their products typically come with a 25-year warranty against manufacturing defects.
  • Boral Roofing – Their concrete and terracotta tiles carry warranties from 25-50 years against manufacturing defects.

It's important to note that material warranties often have specific requirements for proper installation, registration, and maintenance to remain valid.

Warranty on ZINCALUME®

The warranty on ZINCALUME® steel roofing covers manufacturing defects that might cause the product to fail prematurely under normal environmental conditions. This warranty specifically protects against perforation by weathering in the natural elements and significant paint deterioration such as peeling, flaking, or excessive fading.

ZINCALUME® is a premium coated steel roofing product manufactured by BlueScope Steel in Australia. It features an aluminium-zinc alloy coating that provides excellent corrosion resistance and reflective properties, making it well-suited for the harsh Australian climate.

The typical warranty period for ZINCALUME® steel roofing is up to 25 years for residential applications when installed correctly. This warranty on ZINCALUME® roofing installation requires proper installation by qualified professionals like our roofer at Adelaide Roofing & Construction to remain valid. The warranty also requires regular maintenance such as removing debris and washing the roof periodically to remove salt deposits and pollutants, especially in coastal areas.

Warranty on COLORBOND®

The warranty on COLORBOND® steel roofing covers manufacturing defects, premature deterioration of the paint finish, and perforation due to corrosion under normal weather conditions. This comprehensive warranty ensures the long-term performance of both the structural integrity and appearance of the roofing material.

COLORBOND® is an iconic Australian product also manufactured by BlueScope Steel. It consists of a ZINCALUME® steel base with a specialised paint system baked on, providing superior colour retention, scratch resistance, and protection against Australia's harsh UV radiation and weather extremes.

The typical warranty period for COLORBOND® steel roofing ranges from 25-36 years depending on the specific product and your location. This warranty on COLORBOND® roofing installation includes protection against chipping, flaking and peeling for up to 25 years, and up to 36 years against perforation. Like all material warranties, proper installation by qualified professionals such as our Adelaide Roofing & Construction roofers are essential for warranty validity. Additionally, the warranty requires the roof to be regularly maintained according to BlueScope's care and maintenance recommendations to remain in effect.

Workmanship Roofing Warranties

A workmanship roofing warranty is a guarantee provided by the roofing contractor that covers the quality of their installation work. This warranty specifically protects homeowners against defects or problems that arise due to improper installation techniques, rather than issues with the roofing materials themselves. Workmanship warranties are essential because even the highest quality roofing materials can fail prematurely if they're not installed correctly. This warranty demonstrates our confidence in our installation skills and provides you with peace of mind that your investment is protected. Unlike manufacturer warranties that cover the physical roofing products, our workmanship warranty specifically addresses how well we installed your roof.

What Are the Influencing Factors for Roofing Workmanship Warranty?

The terms and conditions of workmanship warranties change according to each roofing company, with several key factors influencing the coverage offered. The length and comprehensiveness of these warranties often reflect the contractor's confidence in their work quality and their commitment to customer satisfaction.

Established companies like Adelaide Roofing & Construction, which has been serving South Australia since 2014, typically offer stronger workmanship warranties because we have the experience and stability to stand behind our work for many years. The contractor's expertise level and specialisation in certain roofing types directly impact warranty offerings, with more experienced roofers often providing longer warranty periods.

The complexity of your roofing project also influences warranty terms, with more complicated installations sometimes receiving more specific warranty conditions. Additionally, contractors who use higher quality installation techniques and follow manufacturer specifications to the letter are more likely to offer generous warranty terms because they know their work will stand the test of time.

The local climate in Adelaide, with its hot summers and occasional severe storms, might affect workmanship warranty terms as different weather patterns create different stresses on roofing systems. Some roofing companies also adjust their warranty terms based on how regularly the homeowner commits to maintaining their roof, with some warranties requiring annual inspections to remain valid.

What is the Importance of Roofing Installation Warranty?

A roofing installation warranty is essential for homeowners as it provides financial protection against defects in workmanship that might not become apparent until months or even years after the installation is complete. This warranty ensures that if problems arise due to improper installation, the contractor will fix these issues at no additional cost to you, saving you from unexpected repair expenses that could amount to thousands of dollars.

Beyond the financial benefits, a roofing installation warranty delivers peace of mind knowing that your significant investment is protected for years to come. Your roof is your home's first line of defence against the elements, and having a warranty means you can rest easy knowing that any workmanship issues will be addressed promptly by professionals who stand behind their work.

Roofing warranties also serve as a strong indicator of contractor quality and reliability. Contractors who offer comprehensive, long-term warranties demonstrate confidence in their workmanship and materials. They're essentially promising that their work will withstand the test of time, which reflects their commitment to quality craftsmanship and customer satisfaction.

For Adelaide homeowners, warranties provide continuity of service with the same contractor who installed your roof. This means the roofer addressing any warranty claims will already be familiar with your roof's specific details and installation history. Additionally, many warranties are transferable to new owners, which can increase your property's resale value and serve as a strong selling point if you decide to move.

Roofing warranties also encourage proper installation practices from the outset. Contractors offering strong warranties have a vested interest in doing the job right the first time to avoid costly warranty claims down the track. This benefits homeowners by ensuring attention to detail and adherence to manufacturer specifications during the installation process.

How to Find a Reputable Roofing Contractor in Adelaide with Warranty

Finding a trustworthy roofing contractor in Adelaide who offers solid warranty protection requires careful research and consideration. Start by looking for contractors with extensive experience in the Adelaide area who understand the specific challenges of our local climate, from intense summer heat to occasional severe storms.

Verify licensing and insurance credentials to ensure the contractor meets all legal requirements to operate in South Australia. Proper licensing indicates that the contractor has met industry standards and possesses the necessary knowledge to perform quality work. Check for membership in professional roofing associations, which often require adherence to strict ethical and quality standards.

Review the specific terms of the warranty offered, paying attention to the duration of coverage, what exactly is covered, and any conditions that might void the warranty. A reputable contractor will provide this information in writing and explain all terms clearly without confusing language.

Ask for references from past customers, particularly those whose warranties have been in effect for several years. This can provide insight into how the contractor handles warranty claims and whether they honour their commitments over time.
