How Long Does A Slate Roof Last?

Table Of Contents

Few homeowners would disagree that a slate roof enhances a home’s beauty and value. Even the best slate roofs age, leak, and eventually need to be replaced, even though they are often thought to be virtually indestructible (some have been around for hundreds of years).

Slate roofs come in a variety of sizes, shapes, colours, and styles, but most slate roofs fall into one of two categories: hard or soft. A hard slate has a lifespan of 75 to 200 years, while a soft slate has a lifespan of 50 to 125 years.

Simple Steps to Help Maintain Your Slate RoofSimple Steps to Help Maintain Your Slate Roof

  1. After a long period of rain, inspect your interior spaces for signs of a leak. Look for moisture damage in the attic and throughout your home, including the first floor.
  2. Examine your roof from the outside for cracked tiles or tiles that appear to be slipping or missing regularly.
  3. Look for slates that have fallen around the perimeter of your house.

A yearly routine inspection is much more thorough and should help to prevent any of these problems.

Slate Roofing Annual Maintenance Inspection Tips

Check the Slate Tiles

Despite its toughness, you’re bound to have a broken or slide slate now and then, especially if your house is surrounded by large, mature trees or if there’s been a bad storm. A trained slate roofer can either repair or replace individual slates.

Check the Flashings

You might be surprised to learn that the flashing and gutters are the most vulnerable parts of a slate roof, so maintaining them is critical to keeping your slate roof in good working order.

Flashing is a thin, weather-resistant material made of copper or galvanized steel that is used to seal gaps around windows, doors, gutters, chimneys, and other exterior joints. Flashing is used to prevent water from getting underneath your tiles.

Perhaps because copper flashings are eventually more expensive than galvanized flashings, they typically last about 70 years, as opposed to fifteen to twenty years for galvanized flashings and require regular painting.

Gutter and downspouts are designed to direct water away from your home. There are two types of gutters: box gutters and hanging gutters. Box gutters are built into the rafter of your roof while hanging gutters are attached to the eaves. We inspect your gutters and downspouts for holes and blockages (such as leaves and branches) as well as the stability of the seams.

Check the Chimney

The masonry, flashing, and cap or flue covers are all examined. If any of these are damaged, your home may experience leaks.

Check the Sheathing or Roof Decking

Sheathing refers to the wood panels or sheet material that is attached to the rafters of your roof. Because the tiles are laid on top of the sheathing, the sheathing must be able to withstand the weight of a slate roof and last as long as the slate roof.

Getting a roof inspection, addressing any issues before they become serious, and possibly replacing your roof can make a big difference. Whether or not you plan to sell your home soon, the condition and longevity of the roof over your head are essential.

While the lifespan of your roof relies on the materials used, the installation techniques used, and any damage that may need to be repaired during its lifetime, all of the aforementioned guidelines can assist you in determining when to replace your roof and understanding the potential lifetime value of your new roof investment.
