It’s not that most roofs are poorly constructed – they’re not. Problems occur when minor issues, such as a small flashing failure, a blocked gutter, or a disconnected soffit, are left unattended for an extended period, giving rise to extensive harm. A 25-year shingle roof will only last 15 years if small details like these are overlooked. The tips listed here will not take up a whole weekend of your time, but they will help safeguard a costly replacement in the future!
Do a binocular inspection twice a year
You don’t have to climb a ladder to identify most potential problems early. A good set of binoculars from the ground can reveal curling shingle edges, spots where granules have worn away and the asphalt substrate is exposed, or flashing that’s lifting or separating around the chimney.
Granules are the first thing that should catch your eye. Those mineral granules protect the asphalt from UV degradation; once they’re gone and the shingles begin to dry out, crack, and lose their ability to repel water. Also, check your gutters – granules accumulating in the downspout’s splash zone indicate the shingles are losing more material than they should be.
Do it in spring, after freeze-and-thaw season, and then again in the fall before the roof bears the load of winter. It takes 20 minutes and it’s free.
Keep gutters clear and functional
Water that is trapped needs an outlet and is generally forced underneath the starter shingles at the edge of the roof. It then wicks up to the roof deck (the structural sheathing below the underlayment) and rots the wood.
Clean your gutters at a bare minimum of twice a year, but four times is better if you have trees overhead. And while you’re up on that ladder, check the fascia boards along the roof line for soft spots or paint peeling from the back of the fascia. That’s early rot from water sitting in an overflowing gutter. Fascia replacement is cheap. Replacing a rotted roof deck section is not.
Downspouts matter a lot, too. A clogged downspout backs up the entire system. Run a hose down them to make sure they’re free-flowing before the heavy rain seasons start.
Trim branches before they become a problem
Tree branches overhanging a roof have a double negative effect: they scratch the shingles in wind and rain, and they drop wet leaves on the roof that sit against the surface for days on end – two of the prime causes of moss and algae. Moss and algae aren’t just unsightly, they also cause shingle deterioration because they hold moisture against the surface, speeding the breakup of the limestone fillers in the asphalt.
Clip branches back so they’re at least six feet from the roofline. You’ll also decrease the amount of leaf drop into the gutters, lessen the likelihood of a branch causing damage in a storm, and give squirrels and raccoons a more difficult time accessing the roof too.
Check your attic, not just the roof surface
A roof system comprises all the components located underneath it. Attic ventilation, in particular, the equilibrium between soffit intake vents and ridge exhaust vents, manages the roof deck’s temperature. If this airflow gets blocked, there is a heat buildup in summer causing the shingles to overheat. Then, in winter, the same heat makes the snow melt in an irregular manner, refreezing at the cold eaves, forming ice dams that push water underneath the shingles.
Make sure there is no insulation pushing against the soffit vents and blocking them. This is among the most common issues with residential roofs but is hard to notice. If your attic becomes extremely hot in summer or you have been experiencing ice dams during past winters, it is worth having the ventilation system checked out properly.
Thermal shock – the expansion and contraction of roofing materials through temperature swings – also stresses flashing seals over time. Quality ventilation minimizes the variance of the temperature the materials experience.
Schedule a professional mid-life inspection
Shingles may be the most visible, but they’re not the first element to fail in most roofs. That honor goes to the metal and rubber flashing around chimneys and skylights, along with the pipe boots that transition vent pipes through the roof. These sealing points develop tiny gaps relatively quickly as they’re subjected to massive temperature and humidity swings.
A professional inspection around the 10-to-12-year mark of a 20-to-25-year roof makes sense for most homeowners. A qualified roofing company in Lancaster, PA can assess localized wear from regional weather patterns – including the freeze-thaw cycles common through the Susquehanna Valley – and reseal flashing or replace pipe boots before those small failures become interior water damage.
The cost of that inspection and minor repairs is a fraction of what reactive repair costs. And a roof in good condition has measurable resale value – a new roof consistently returns close to its full cost at the point of sale.
Small maintenance, large returns
A roof is not just one material but rather a group of drainage, ventilation, and water barrier systems that rely on each other. If one element fails, the others try to make up for it until they can’t anymore. Homeowners who re-roof at 15 years rather than 25 will almost always find that the cause was seemingly insignificant neglect.
