Roof Replacement vs. Roof Restoration: Which Is Best for Your Home?

Maintaining your roof is important to preserving the integrity of your home. Roofs are exposed to harsh weather, UV rays, and general wear and tear, requiring attention to ensure they remain functional.

Two common options homeowners consider are roof replacement and roof restoration. But which one is right for your property?

What Is Roof Replacement?

What Is Roof Restoration?

Roof replacement involves completely removing the existing roof and replacing it with new materials. This process is necessary when the roof is beyond repair due to severe damage, age, or material degradation. When to Choose Roof Replacement: Extensive damage, such as sagging or large leaks. Your roof is at the end of its lifespan (e.g., over 20-30 years old for tiles). Structural damage or decay. At AllCoast Roofing, our roof replacement service covers both tile and metal roofs, offering high-quality Colorbond options for those looking to upgrade. We handle everything from insulation to solar panel reinstallation, ensuring a seamless transition to your new roof.

Roof restoration involves repairing and rejuvenating your existing roof to extend its life. This process includes cleaning, repairing damaged sections, and applying protective coatings. It’s an ideal option when your roof is showing signs of wear but is still structurally sound. When to Choose Roof Restoration: Minor leaks, cracked tiles, or faded paint. Moss or lichen build-up. The roof is under 20 years old and structurally intact. At AllCoast Roofing, our roof restoration process includes cleaning, repairing, and repainting roofs to give them a new lease on life. We use Dulux Acratex Roof Membrane, one of the best products on the market, ensuring a long-lasting finish that looks great and provides excellent protection.

Differences Between Roof Replacement and Roof Restoration

• Cost:
  • Roof restoration is generally more affordable than a full roof replacement because it focuses on repairing and improving the existing roof structure. Restoration includes installation of sarking, this could start at $10,000 and can exceed $25,000 plus GST depending on the size of the roof.
  • Roof replacement is a larger investment but is essential for severely damaged roofs.
• Timeframe and Disruption:
• • Roof restoration takes less time, as it involves stripping the roof back to the truss, installing sarking, and replacing broken tiles. After cleaning we apply a primer/sealer then we finish with two coats of high-quality roof membrane paint.
  • Roof replacement is more time-intensive due to the removal and installation of new materials.
• Longevity:
  • Roof restoration can extend the life of your roof by up to 10–15 years.
  • Roof replacement gives you a brand-new roof that can last 20–50 years, depending on materials used.
• Aesthetics:
  • Both options can significantly improve the appearance of your home, but roof replacement allows you to completely change the roofing material and style.

When Should You Consider Roof Replacement?

If your roof has suffered extensive damage or has reached the end of its lifespan, replacement is likely the best option. Common signs that you need a new roof include:

• Major leaks or water damage.
• Roof sagging or buckling.
• Rusted or cracked roof materials.
• Widespread tile or metal deterioration.

AllCoast Roofing provides full roof replacement services, including tile re-roofing and tile roof restoration.

When Is Roof Restoration the Best Option?

Roof restoration is suitable when your roof is still structurally sound but requires some repair to function properly. It is often recommended in situations like:

• Minor leaks and cracked tiles.
• Faded or worn roofing surfaces.
• Moss or lichen build-up that can be removed with pressure cleaning.

Our roof restoration process, first install safety measures such as roof rails for two-story homes. Next, we strip the roof down to the truss, removing battens, tiles, and cappings, and then install heavy-duty sarking before reinstalling everything and replacing any broken tiles, which comes with a 5-year leak-free warranty.

After thoroughly cleaning the roof with high-pressure water blasters, we apply a primer/sealer by Dulux to prevent calcium salt absorption and enhance adhesion.

Then, we apply two coats of Dulux Acratex 962 Roof Membrane in your choice of gloss or satin, backed by a 5-year leak-free warranty and a 10-year labour warranty. Finally, we ensure the site is clean and remove any debris.
