"Contacted WE Griffin in the afternoon and they scheduled us the following morning. Matt showed up on time and did a thorough review. Leak was thought to come from plumbing not roof. Rather than having us incur potentially unnecessary cost for work that wouldn’t fix our problem, Matt was honest and very knowledgeable. In addition, no cost for his visit. Although we didn’t pay for any services, our interaction with Matt and WE Griffin has made us customers of theirs for any roof related matters going forward. Would absolutely recommend."

"A previous roofer could not stop the leaks coming from one of our skylights. Dan from Central Exteriors did an excellent job diagnosing the problem and fixing it. I highly recommend Dan and Central Exteriors for your roofing needs."

"Presidential Exteriors is a great company to do a roof replacement with! We had our roof replaced in early February 2021 and we couldn’t be happier. The whole team was amazing to work with. Nate worked closely with us every step of the way to make sure we were happy and getting the best product and prices possible. He really made us feel like family. Elena was great at communicating every step of the process. The day of installation team was amazing. They dropped off the equipment one day before the project even though it had snowed the night before. The morning they came to do the roof, we still had ice on the roof, but instead of delaying the project, they scraped all of the ice off our roof and still got the whole roof done in one day! Our new roof is great and we couldn’t be happier. We very highly recommend Presidential Exteriors for any roof inspection and roof replacement. We will absolutely be keeping them on our list for any future projects with our house."

"Sunny showed up on time to give me an estimate for repairs, showed the pictures of the work to be done and gave me a very reasonable price, then did the work with materials he had that matched what was already on the roof. I don't this entire process took more than an hour. The added bonus was working with someone who was actually customer service oriented."

"Certified roofing did very well. They were the first to respond to my Angi query. Tim was smart, quick, and had an excellent work ethic. We had a slight miscommunication on what the job entailed, which is being cleared up as we speak. I would definitely hire them again."

"Service went great. Available dates were a little backed up but reasonable. The technicians, Mikey and Garret, showed up on time and called with a 20 min ETA. Service was well explained, with pictures, and honest assessment of the roof's condition was given without aggressive upselling. Work was conducted quickly and done well. I used Arocon for my roofing needs at a prior residence and will use their services again."

Roofing questions, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.

You can put a green roof on a regular house with a compatible slope. Green roofs are best suited for flat or gently sloped roofs, as steeply pitched roofs can make the installation and maintenance of the green roof challenging. Flat roofs can support the weight of the soil and plants and ensure effective drainage.

While it’s technically possible to repoint a chimney without scaffolding, it’s not recommended, especially for taller chimneys. Scaffolding provides a stable platform that allows for safer and more precise work. Without it, you might find yourself in a risky situation, and the quality of the repointing could suffer.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.
