Why Homeowners Choose Autumn to Repair or Replace a Roof

Knowing when to replace your roof is tricky in New Jersey because of the crazy seasons. Although temperatures get cooler in the fall, the weather is usually quite mild.

For starters, many homeowners find they need to schedule a roof appointment after summer’s heat, rain, and hail. The cost of a roof inspection is usually well worth the money spent. Also, homeowners need to keep their gutters clear during this time of year (we’ll tell you why below).

But in general — due to the mild weather — late summer and early to mid-autumn are usually the best time periods to research roof replacement contractors. Temperature extremes are not a problem when it comes to laying shingles and sealing them. Roofing contractors can fill up quickly in the fall, so booking early is something to consider.

Why is Fall the Best Season?

Regularly checking for falling debris, cleaning gutters, adding gutter guards, checking for damages or leaks, properly insulating your attic, and making miscellaneous repairs should be on any homeowner’s roofing to-do list going into the fall.

Considering a new roof should also be on the list. Here are the reasons why:

  • If you notice any damage to your roof after summer weather, you should inspect it immediately. As late summer is transitioning into autumn, this period is the best time to check whether your roof needs to be replaced before colder weather hits. Hail and heat can cause damage from spring to summer. If you think you might need an expert opinion to get a pulse on the health of your roof, schedule one immediately with a certified roof inspector near you.
  • New Jersey has temperatures in autumn that aren’t too hot, yet they aren’t too cold. Thermal sealing occurs when asphalt shingles melt at 45 to 60 degrees Fahrenheit on a clear day. That way they can adhere appropriately. As a result, your roofers will be able to spend more time on the job since the temperature will not be excessively hot or cold — as well as meet project deadlines. Rain delays are less likely to occur if you start work earlier in the fall. Your shingles will seal effectively before the snowy months when temperatures are perfect with low humidity and little rain.
  • If you want to prevent your shingles from getting ruined by frigid temperatures, seal them now. The colder the air, the more brittle shingles become. The good news is, they are protected from snow and ice with a sealant, so they won’t be blown away in the winter wind.
  • Your winter energy bill will be lower. Replacing your roof will help your HVAC system perform at its best, especially if the system happens to be located in your house’s attic. Keeping you and your guests warm this winter, a roof replacement or repair can also save you money on heating.
  • As temperatures cool, it’s the perfect time to repair holes and other problems. You can maintain your roof now before it becomes a problem. By taking care of problems now, you’ll avoid paying for more expensive ones in the future.

What Temperature Should a Roof Be Replaced?

It’s recommended you replace a roof between 40 and 85 degrees Fahrenheit since installing shingles below 40 degrees can increasingly lead to brittle material that’s easier to break. However, sometimes a roof needs to be repaired or replaced in sub-40 degree temperatures.

If you’re a homeowner who is storing roof materials before they are installed, keep them warm (above 50 Fahrenheit) until your contractor is ready to use them. Also, keep your shingles completely dry.

Remember: the age of a roof isn’t the only factor to consider when asking yourself or a roofer about your next roof replacement timeline. There are other considerations to make that can help you determine the right decision for your home.

What’s the Average Time it Takes to Replace a Roof?

There is no one-size-fits-all answer to this question. It usually takes one day to replace the roof of an average-size residence depending on the circumstance at hand. You can expect it to take between three and five days if weather, complexity, and accessibility of your home are issues. Sometimes, even a two- to three-week wait is not uncommon given any potential extreme situations.

House roof replacement time is determined by a few factors:

  • In cold weather, additional steps will have to be taken to replace the roof.
  • Shingles come in a variety of materials and designs. There is a different installation method and time required for each material.
  • Larger houses require more time to replace their roofs. It will take much less time to replace the roof on a small cottage than it would on a large house.

What of You Wait Until Winter?

Preparing well ahead in the autumn for what winter can do to your roof is the best way to enjoy winter. But sometimes homeowners wait longer. Winter roof problems can happen to any home, so it’s important to be prepared.

Check your roof before the first snowstorm arrives and determine if there is any damage. You might be able to prevent a more serious issue from occurring if you can catch and address a problem early on, which could ultimately save you money. Keep an eye out for the following problems over the winter season, even if your roof appears to be in great shape:

  • Dams Created by Ice — During the winter months, icicles may pose a threat to your roof and property. Ice dams prevents melting snow from draining properly off the roof because they form at the roof’s edge. As a result of excessive accumulation of melted snow, a roof (and sometimes interior) of a home can be damaged.


Home attics often suffer from inadequate ventilation or insulation, resulting in ice dams. When you discover your roof has ice dams, you should call a professional to assist you. In order to prevent further damage to your roof, you should constantly inspect it for signs of weathering after ice dams have been removed.

  • Attics with Condensation — Condensation can form in a warm attic under a cold roof, leading to mildew, mold, roof failures, and structural damage to your home. In most cases, poor ventilation causes attic condensation, which is a complex issue that requires professional guidance. You should contact a professional if you notice condensation in your attic. The right expert can help you remedy the situation and ensure it doesn’t happen again.


The installation of roof vents and insulation can help prevent condensation. You can avoid other winter roof problems such as ice dams and leaks, as well as frozen gutters and other issues. During the early fall, before the snow falls, is an ideal time for installing roof accessories.

  • Leaks Around Flashing — Water damage is prevented by flashing, a section of sheet metal that covers the joints in a roof. It’s most common to use flashing around chimneys, skylights, and windows where leaks are likely to occur.

A roof inspection is necessary if you notice leaking around these areas due to damaged or weathered flashing. Roof flashing should be inspected routinely by a roofing inspector to prevent larger problems. The cost of fixing flashing is much lower if you catch it early. It’s possible to encounter greater and more expensive issues once the water has leaked through and caused damage.

  • Gutters that Freeze-Over — This typically occurs as a result of ice dams, though they are not always connected. New Jersey can sometimes experience a quick snowstorm, but then the sun is shining the next day. This causes water from the roof to drain into gutters. The temperature drops before the gutters can properly drain all the water, freezing any remaining water. In most cases, leaves clog up the drainage system.

Once the temperature rises again the next day, the water begins to leak into the walls, siding, and windows. Keeping your gutters clear of debris and drilling a few holes in your gutters will prevent this from happening. The problem of freezing gutters can usually be solved if you solve the problem of ice dams. During the fall and winter, gutter guards can also prevent gutters from clogging.
