The summer sun brings intense heat and brightness but it also introduces serious wear-and-tear threats to your roofing system. Especially here in New Jersey, where seasonal heat and humidity can accelerate roof deterioration, UV rays and thermal cycling weaken materials, reduce energy efficiency, and lead to expensive repairs. This guide breaks down how sun exposure impacts roofing in NJ and offers practical, preventative steps to keep your home protected.

How UV Rays Impact Roofing Materials

Asphalt shingles can dry out, crack, and lose protective granules over time
Wood shakes may fade and become brittle under direct sun exposure
Metal roofs expand and contract with heat, which can degrade fasteners and finishes
Flat roofs with rubber or TPO membranes are prone to warping and blistering in prolonged heat

Curling or cracking shingles
Bald patches where granules have worn off
Faded or discolored roofing materials
Exposed nail heads and dried-out caulking

Heat Accumulation and Your Roof

Thermal cycling (expansion and contraction) causes material fatigue
Trapped attic heat accelerates damage to decking and insulation

Prevention and Protection Tips

Schedule annual roof inspections during late summer
Install a radiant barrier or reflective roof underlayment
Consider cool roof coatings to reflect UV rays
Improve attic ventilation to reduce heat buildup
Use lighter-colored roofing materials to deflect solar energy

Benefits of Cool Roof Coatings

UV protection prolongs shingle life
Energy efficiency improvements (lower attic temps)
Potential utility savings during peak heat months

Jonathan and his crew replaced our roof, removed a built in air conditioner, and installed a new window. They were courteous, responsive, professional, and did great work for a fair price. I've had many roofing jobs done by several companies, and these guys are the best of the bunch. Highly recommended!

We recently worked with John for our home siding and gutters and were thoroughly impressed. John combines youthful energy with old-world business values that are increasingly rare today. He was attentive, focused, and genuinely listened to our needs without pushing unnecessary upgrades.
What stood out most was how he treated our home as if it were his own, recognizing it as one of our biggest investments. The results are stunning—our house looks incredible! We highly recommend MoCo to anyone seeking quality work delivered with integrity and respect.

We had a great experience with Jonathan and his team. The foreman, John, ran a clean, professional job. Although extreme winds made the work challenging, they went above and beyond by walking the street to collect any debris that may have blown around. Their attention to detail is impressive and truly a lost art. While we had no issues, it’s clear they stand behind their work and would make it right if anything didn’t meet expectations. Highly recommend!

I needed an evaluation of my roof as well
As a quote to have it replaced. Time was important as I was in the process of selling my house. John came the same day I called, fully inspected the roof and provided me the documentation I needed to give to the buyer. John was extremely professional and pleasant. Thanks John!

We had 1 piece of siding that detached. We called the company that installed it 4yrs ago, expecting them to stand by their work and fix the improperly installed piece. Instead, they gave us a ridiculous estimate to replace it. We called John at MOCO based on other Google reviews & could not have been happier with the service provided! He gave us an estimate the same day we reached out to him & 2 days later he was back making the repair at a fraction of the cost of the other estimate. And after one extremely windy week, the siding piece stayed put! Highly recommend John at MOCO and we'll know who to call for any future needs!

As someone who knows very little about this industry I came across Morris County Roofing and Siding LLC for roofing. The amount of questions and concerns I had going into the phone conversation was put to rest once speaking to the owner. His professionalism and knowledge he offered was greatly appreciated. I will definitely be giving this business another call back once I am ready to take the next steps to move forward with the roofing improvement our home needs.

We could not be happier with our experience with Morris County Roofing and Siding. The entire process was easy, comfortable, efficient, hassle-free, and tidy. I know nothing about roofs except that I needed a new one. Jonathan met with us, used his drone to take photos of our rooftop, and went through our crawl spaces. He then explained everything honestly and thoroughly which put me at ease. The workers were timely, fast, and didn’t leave anything behind. I would recommend this company to anyone needing a roof or siding without hesitation.

Jonathan the owner of Morris county Roofing and Siding was on site the whole time while his crew was working. John and his crew are very respectful. During the free estimate he flew his drone over the house to show us live the condition of the roof. He then crawled inside the hot attics to see if there was any mold. Then proceed to show us the condition of the interior roof. Where we did have mold it was replaced with fresh boards. He was very honest on what was needed to be done and to not up sell. During the roof replacement his crew was very courteous to place tarps all around the house to keep the mess contained. He is very kind to his crew as well. He made sure his crew was hydrated throughout the day and made sure they stopped for lunch which he provided for them. The pricing on the roof was extremely competitive. Excellent quality roof for a fantastic price. He did not cut corners on materials giving us plenty of ice and water shield and improved ridge vents. Highly recommend Morris County roofing and siding to anybody who needs a roof.

Great experience with Jonathan and his crew. He replaced the roof, fascia, gutters and downspouts. The work was done in accordance the schedule given, one day for the roof and one day for the other things. The price was reasonable and Jonathan was easy to work with. Lastly, they cleaned up the yard thoroughly, without prompting from me.

Jonathan is extremely knowledgeable and experienced. He takes time to educate his customers and cares about the end result. He’s done two phases of replacing a formerly installed shingle roof with the proper flat roof as mine is a low pitch in the back. Thank you for the great work and service.

I deal with contractors all the time and sometimes you can be rolling the dice(never know what you’re going to get) With Jonathan from start to finish, from the communication to the high quality install i wouldn’t of changed a thing. Thanks again Jon!

Jon gave us a great roof at a cost effective rate and if I had a thousand roofs I'd call him for each and every one. As a contractor myself, I didn't have any questions that he couldn't answer and my wife and I are happy knowing we have a roof that is going to last us a very long time!

So glad we used them for our new gutters and siding. We originally wanted to do James Hardie siding, but Jonathan recommended a similar product called LP Smartside— did some research before committing and it ended up being better looking, more durable, AND more affordable. Really happy with all of their advice and with the job they did on the install. Zero complaints.

I couldn’t be more thrilled with my new roof, I received several estimates and hired Moco because they were competitively priced and used quality products. My three layer roof was replaced in one day, and I could not be more impressed with the cleanup. I have not found a single nail. I also want to give credit to the project manager, Jon he gave me the estimate and supervised the job from beginning to end. I would recommend Morris County roofing and siding to anyone.

Jonathan and his crew did an amazing job replacing my roof. The crew was very professional, worked diligently and left my property as clean as it was before they started. Jonathan kept me updated throughout the day providing overhead drone shots of the crews progress which was very appreciated and reassuring since I wasn't home during this process. I have received compliments from neighbors who witnessed the progress of how organized and professional the team was. Pricing was very reasonable as well. I would highly recommend them.
