If a roof is allowed to age for a long enough period of time, no one would be able to ignore the signs that it requires replacement. You don’t need a master’s degree in roofing to appreciate when water is trickling down your walls or light is visible through your ceiling.
Naturally, you would rather replace your roof before it makes your home uninhabitable. That is why you ought to look for the 6 signs you need a new roof. Heeding them will save you considerable inconvenience – not to mention money, as you avoid having to deal with mildew and other types of damage.
1. Your Roof Is Old
Every roof has a life expectancy. It may be extended if your home is in an gentle climate, or shortened if your home is located in a climate that treats its residents to strong winds, hailstones, and extreme temperatures (Sioux Falls’ climate is an excellent example of a less hospitable climate).
While several factors impact how long a roof can go before it needs replacement, the National Association of Home Builders offers realistic guidelines to how long each kind of roof can last.
Aluminum: 3 to 7 years
Asphalt: 20 years
Modified Bitumen: 20 years
Fiber Cement: 25 years
Wood: 30 years
Coal and Tar: 30 years
Simulated Slate: 50 years
Slate: 50 years or longer
2. Your Shingles Are Missing or Damaged
Wind, hail and fluctuating temperatures are the enemies of shingles. If a storm has recently left your roof partially unshingled, then you likely already know it’s the right time to Google “roofing contractors Sioux Falls” or “roofing repair Sioux Falls.”
But not all signs of roof damage are so obvious. Look for curling, buckling or blistering shingles, as none of these can effectively repel rain or meltwater. The hail damage Sioux Falls is famous for may leave indentations in shingles that are only visible through binoculars. Also be on the look out for large branches next to your home, as they may have landed there after striking your roof, as well as coarse granules in your gutters. Its protective granules are essential to a shingle’s functionality!
3. Your Flashing Is Damaged
Flashing is a thin sheet of metal that guards a roof against water infiltration. It is typically made of steel or aluminum – which, unfortunately, are both vulnerable to corrosion over time. If you notice rusting, curling or cracking of the flashing around your vents, chimney, skylight, or any other roofing junction, then extensive damage to your roof is inevitable unless you seek immediate repair or replacement.
4. Your Roof Is Spongy
We advise against walking on your roof! Gravity makes doing so far too dangerous without proper training and safety equipment. But if you were to walk on your roof, and noticed sponginess, you would have sound evidence that an inadequately ventilated attic caused heat damage to your shingles and the wooden decking just beneath them. Fixing an attic’s ventilation problem may be enough to correct this problem, but oftentimes the damage is so extensive that total roof replacement is more economical.
5. Your Roof Is Sagging
A roof may begin to sag if it suffered water damage, buckled after being subjected to the immense weight of heavy snowfall, was poorly installed, or simply aged for too long. In rarer cases a sinking foundation may also have caused a roof to sag. A sagging roof doesn’t necessarily demand replacement, as simple reinforcement is often sufficient to reverse the damage. But given enough time, a bowed roof will fail to repel the elements – or worse yet, collapse altogether!
6. Your Roof Has Been Colonized
Regularly inspect your roof for the three M’s: mold, moss and mushrooms. Any of these organisms could indicate that your soffit vents have become clogged and allowed moisture to infiltrate your attic. If you catch any of the M’s quickly then you may avoid a big problem, but if they’re allowed to colonize your roof long enough they can destroy the shingles and the decking. The moisture which bred them may also spread to the frame, where it will eventually allow mildew to take root.
On a side note, be on the lookout for bats. The nocturnal scoundrels may not destroy a roof, but the hole they use to access your home can spell sizeable damage in the future. Bat “leavings” may also breed histoplasmosis, a fungus which can cause flu-like symptoms and even death.
