Factors Effecting Roof Lifespan


Don’t Let These Common Roof Myths Fool You

How knowledgeable are you when it comes to roofing matters? It’s important for homeowners to have a solid understanding of the different parts of their roof, as this enables you to make informed decisions when it comes to roof repairs and replacement. At Turnbull Roofing, we want to help you be informed homeowners by debunking some of the most common roofing myths!

All Shingles Are the Same

It’s important for homeowners to remember not all shingle options are of equal quality. Higher-quality shingles, such as architectural shingles, tend to be heavier and stronger, which allows them to withstand more intense weather conditions without wearing down.

Your choice of shingles will impact your roof in the following ways:

  • How long it lasts before repair or replacement is needed;
  • Your roof’s exterior appearance;
  • As well as factoring into the resale value of your home.

The More Insulation the Better

Believe it or not, there is such a thing as too much insulation. Having excess insulation can cause your roof ventilation to become blocked. When this happens moisture is trapped in your roof and can lead to rot and warping.

It’s Better to Lay New Shingles Over Existing Ones

Although this can be a realistic option in certain scenarios, it’s generally best to remove old shingles before laying down new ones.

When replacing tiles, it’s important to remember the sheathing underneath your roofing tiles. Without removing old shingles, issues with sheathing may go unnoticed and can lead to roof rot, leaks and other costly damages.

Flashing Only Needs to Be Replaced with a New Roof Installation

Flashing serves the purpose of diverting water away from vents, pipes and joints on a roof. It’s important to check your roof’s flashing regularly, to ensure none of the shingles or caulk in contact with it are damaged.
