Did you know that the average cost to replace a 1000 sq. ft. roof is between $3,400 and $9,000? And that’s for a relatively modest-sized roof. start throwing in a few extra square feet and gables, and you’re looking at a hefty bill.
So it’s no surprise that many of us are asking ourselves, what is the average lifespan of a roof? It’s good to know so that you can start budgeting for a replacement. Also, it can help you to see what you can do to extend its useful life.
Let’s take a closer look and see exactly how long we can expect our roofs to last.
What Is the Average Lifespan of a Roof?
The average lifespan of a roof depends on where it is built and what it is made of.
The exposed position of our roofs makes them very susceptible to damage. If you live in a very hot or humid part of the country, the sun can cause shingles to expand, weakening the integrity of the roof.
Storms can do a lot of damage, removing shingles and causing water ingress. Without regular roof care after storms, the lifespan of roofs can drop significantly.
Roofing Material Lifespan
The lifespan of a roof made from a hard-wearing material like slate is much greater than one made from rolls of asphalt. The average roof lifespan is:
- Composite shingles – up to 40 years
- Wood shingle – up to 30 years
- Standing-seam metal – up to 50 years
- Clay or cement shingles – up to 100 years
- Slate – over 100 years
Remember, these are only averages. Find a contractor who installs high-quality roofs and does prompt repairs and you could extend this by some margin.
How to Extend the Lifespan of a Roof
To extend the lifespan of your roof, keep threats to it to a minimum. This means:
- Trimming overhanging tree branches that could fall on it
- Keeping gutters clean throughout the year
- Keep your attic well ventilated and insulated
- Clean your roof every year
If you don’t keep your roof clear of moss, mildew, and mold they can gradually eat away at the roofing material. Depending on the elevation, you may be able to clean this from the ground with a telescopic handled brush, dish soap, and water.
Annual Roof Inspection
Whether you suspect roof damage or not an annual roof inspection is essential for your peace of mind. The fall is a great time to do this before the harsh weather of winter.
The inspector will look for:
- Signs of structural damage
- Missing shingles, stains, rust, damage
- Interior inspection – signs of leaks
You’ll get a detailed report explaining any remedial action that you need to take.
