How Winter Affects Your Roof

Many do not put much thought into their roof until they notice an issue with their homes protective cover. You may think between the shingles, leak barriers, and everything else you saw being installed that it is impervious to any damage. It is easy to fall for this common misconception as you have little reason to go up there and check it out. However, knowing what your roof is exposed to and how it is affected by these conditions can save you money in the long run. To help you develop a better understanding of your roofing and how to maintain it, our roofing experts have explained how winter affects your roof.

Snowfall: Snow accumulation can pose a dangerous threat to a roof and everything beneath it. Every cubic foot of fresh snow resting on your roofing system can add up to 20lbs to the weight it is already supporting. As the snow melts and refreezes, it becomes denser and increases each cubic foot’s weight up to 60lbs. While slanted roofs encourage the snow to fall off and distribute the weight better, flat roofs are left with the task of supporting hundreds of pounds of snow until it melts or is manually removed. If left unattended, it can crack supports and lead to a sagging system that needs to be entirely removed.


Freeze/Thaw: As the ice melts, the runoff can find its way into tiny cracks and become trapped. Once the temperatures drop, the water will freeze and expand, widening the opening and allowing water to leak into your Cherry Hill home’s roofing.

Thermal Shock: Since we live in an area where the temperature can drop into the single digits during the night and then hit the mid-40s by noon, thermal shock is a major threat to your roof. As the roof is quickly warmed and cooled, the molecules in the shingles and other materials will lose their tensile strength and lose the ability to expand and contract. Once they can no longer do so, they will become significantly more brittle and likely to crack as the temperatures drastically change.

Now that you have an understanding of the conditions that your roof deals with every winter, you are better prepared to detect when your roof may need a repair or maintenance. If you suspect that your roofing system has been damaged by the harsh winter weather, give Alan Cherry’s Exteriors a call and we will send a general contractor to inspect the roof in Cherry Hill, NJ.

Signs Your Roof is in Need of Repairs

Many think that the only way they can tell if their roof has any damage is to get up there and look at it. While getting a close up look at the roof will give them a detailed idea of any issues, it is not necessary. You can form a good idea of what is wrong with your roof while keeping both feet firmly planted on the ground. One thing to keep in mind before beginning your inspection is the age of your rooftop. On average, one that has received regular maintenance will last for 20 to 25 years. Our roofing experts have laid out several issues to look for to help you determine if you need to look for contractors in South Jersey.


Leaks: Before going outside, go to your attic and look for signs of leakage. If you can, look behind the insulation for wood that appears damp. You should also look for peeling paint and signs of mildew and mold growth as they can be signs that your roof is leaking.

  • Curled/Buckled Shingles: As the shingles reach the end of their lifespan, they may begin to curl or buckle. Excessive heat and moisture trapped under them can also cause them to lose their shape. It is important to address curled and buckled shingles as they make it easier for wind to tear them off and for water to enter the house.
  • Cracked/Missing Shingles: High wind speeds and hail can easily shred apart an older roof, allowing water to seep into the house and under the rest of the roof. If you notice any are broken or missing, you should call Alan Cherry’s Exteriors to repair the roofing immediately.
  • Missing Granules: If your shingles begin to look dirty or you are finding a large amount of granules at the base of the gutter after a rain storm, you will likely need new shingles installed. Granule loss can be the result of age or the improper placement of a drainage system.

Looking for these signs during your ground-level inspection of the roof will help determine if you need to begin your search for trusted South Jersey contractors. If you suspect that there is an issue that should be addressed, give Alan Cherry’s Exteriors a call today!

A Brief Roofing History

globe-thatched-roofAlan Cherry’s Exteriors has been one of the most trusted Cherry Hill roofers for over 40 years, but the history of roofing goes back much further. Roofing dates back to at least 40,000 BC, when people used animal skins such as those of the woolly mammoth. Evidence of this type of shelter has been found in Siberia, Russia. Slating and tiling became the norm in ancient Rome in roughly 100BC, borrowed from the glazed clay roof tiles used in China 5,000 years ago and the flat earthenware tiles used in Greece and Babylon Thatched roofs came on the scene in 735AD. Thatched roofs were the most commonly used method for about 300 years before wood shingles made their debut.

In the 12th century, King John of England decided to trade the thatched and reed roofs of London for clay tiles. This law, passed in an effort to reduce the spread of fires, may have led to the mass production of roofing materials.

The early 19th century saw an increase in the industrial production of clay roofing. Concrete tiles were developed about 100 years later and became quite popular because they are easy to mass produce at a low cost. Most of the known changes in roofing happened in the last 200 years, and, as with many scientific developments, have advanced more quickly over time.

Today, wood, metal, slate, and tile roofs are all in use in different parts of the country and the world depending on the customer’s needs. Visit Alan Cherry’s Exteriors for all your Cherry Hill roofing needs.

Plastic Thatch could change Thatching and Recycling forever

Alan Cherry’s Exteriors builds and repairs roofs for all types of homes in many different neighborhoods throughout Philadelphia and South Jersey, but we’ve never seen anything like this. David Saiia, a professor of sustainability and strategic management at Pittsburgh’s Duquesne University, has developed plastic thatch, a sensible alternative to traditional thatched roof design. Generally, the residents of poor nations who live under thatched roofs rely on certain grasses, which make leaky roofs that insects live in, and corrugated tin roofs, which trap heat and create an uncomfortable living space.


Plastic thatch has provided a solution to these more rudimentary building materials. And because plastic thatch is made from discarded plastic bottles, the method serves as a great form of recycling. The project is part of Saiia’s strategy to help indigenous people out of poverty while preserving the surrounding habitats. After seeing the plastic bottle debris all over the scenic Andes cloud forest on the Ecuadorian nature preserve Maqui Picuna, Saiia tried to come up with something to do with all the garbage. Turning it into building material helps deal with both the pollution and the housing issue.

An unintended but welcome side effect of plastic thatch was that as the roofs gradually collect dust and dirt and turn into NOGRs or Naturally Occurring Green Roofs. The prototype roofs in Maqui Picuna grew rare orchids and bromeliads. Additionally, the soil diffuses direct sunlight, increasing the life of the roof.

Although Alan’s Cherry Exteriors is probably not going to add plastic thatched roofing to our list of services any time soon, we always enjoy sharing innovative ways to build and repair homes.
