What is reroofing? Put simply, reroofing is updating or replacing a building’s current roof.
There are two main methods of reroofing: roof overlay vs tear off.
The overlay reroofing method involves keeping your existing roof and adding a layer of shingles on top. On the positive side, this style of re-roofing is less expensive and take less time to complete. However, this is not a long-term fix and this style of reroofing can make it more difficult to track leaks inside your roof. Please note that you can only choose this reroofing option if your roof has not had a previous overlay installed.
The tear-off method of roof replacement involves your roofing company tearing off your existing roof to replace it with an entirely new roof. This style of reroofing will completely fix any damaged decking or leaks present in your roof, will last much longer than an overlay, and add value to your home’s resale value. However, this method is often more expensive.

How Can I Tell If My Roof Needs To Be Replaced?
Here are possible signs your roof may need to be replaced:
- Curled shingle edges: Your shingle edges are curled or shingle tabs are cupped
- Missing granules: Your roof has bald spots where granules are missing
- Cracked shingles: Your shingles have cracked.
- Algae or moss: Airborne algae and moss can create dark streaks on roof decks.
- Your roof is old: As your roof materials approach the end of their lifespan, they will start to break down and this can jeopardise the integrity of your roof.
How Many Years Do Roofs Last?
Slate tile roofs: Nothing beats a slate tile roof for longevity. Hard slate will last between 75 and 200 years, while soft slate will last between 50 and 125 years.
Metal roofs: Copper and zinc roofs can last for more than 100 years, while aluminium or steel roofs can last for more than 50 years.
Terracotta roofs: Terracotta roofs generally last for up to 50 years.
Concrete roofing: Concrete roofs have an average lifespan of 50 years.
Asphalt roofs: Asphalt roofs typically last up to 25 years.
Wood shingle and shake roofing: If you want your wood shingle roofing to last for more than 20 years, always keep it dry and well-ventilated. Apply treatments against water, insects and UV-rays. You also need to regularly clear the roof of any flammable materials like dried leaves and dead branches.
