According to the International Association of Certified Home Inspectors, some roofs can last as long as 150 years if they’re well maintained.
So, you might think you’re in the clear when it comes to roof replacement. Unfortunately, that’s not the case.
Environmental factors play a huge role in how long a roof lasts, and most older homes will need a new roof within 20 years or less.
Here’s how you know when to get a new roof.
Your Shingles are a Shambles
Take a look at the parts of your roof that get direct sun. Do you notice that the shingles in this area aren’t quite flush with the roof profile?
Curling and lifting shingles are a sure sign that roof repair is in order.
Check if all your shingle tabs are intact. Over time these tabs can break down and detach from the nails that hold them in place.
When this happens, your shingles will part ways with your roof in high winds.
Missing shingles can cause serious roof problems. You need urgent roof maintenance or replacement.
Droopy, Spongy, or Saggy Bits
The lines of your roof should be absolutely straight when viewed from a distance.
If you notice any curves or swag at the top of your roof, your roof could be retaining water.
You’ll also notice the rafters or decking in your attic sagging if this is the case.
Moss, lichen, algae, lichen, and fungi love moisture, so if you have them growing on your roof there’s a good chance it’s retaining water.
These plants take time to establish themselves, so it’s also a sign that your roof’s past its prime.
A new, expertly constructed roof comes with a long guarantee, so it’s worth the cost of getting a new one.
Read on here to see how long a guarantee you could get nowadays.
The Light Shines Through
Head up into your attic and notice if the sun shines in. Do you notice that your attic boards seem spongy?
You may notice moisture in the insulation too. All these are sure signs that your roof’s leaking into your attic.
Granules in Your Gutters
New shingles have a coating of fine, weather-resistant stone. Over time, these loosen and wash away in the rain.
They’ll usually end up in your gutters but you may also notice your roof has lighter patches where the granules have worn away.
If the flashing around your chimney, skylights, or vents has seen better days, it will leak.
Older flashing’s usually made from roof cement or tar which breaks down over time.
It’s best to replace old-style flashing with modern metal flashing if you want your roof to last longer.
New Roof Rewards
A roof replacement isn’t one of the most glamorous or noticeable home upgrades, but it is an important one.
