"Rather than talking me into an entire new roof, which I was prepared to do if necessary, they recommended just replacing a few shingles for a very reasonable cost! The only reason I didn't hire them was that another company (who also just recommended replacing a few shingles) also mentioned that some of the gaskets around pipes were cracked and suggested replacing them also. They showed photos, which clearly showed that they needed replacing (at least from a layman's viewpoint), so I went with them. W E Griffin was quick and efficient with their estimate, and I wouldn't hesitate to call them again."

"Our self-managed HOA very much appreciated CE's (especially Artem's) straightforward demeanor. CE was able to replace our roof that had apparently been done poorly during its 2005 reno. When water continued to come into our home, they were willing to come back to install a diverter to help mitigate the issue from continuing. We are hoping that it will be effective but we do not yet know for certain until we get rain."

"We were convinced to have our roof done after the roofing expert inspected our roof and sat us down for his presentation. We appreciated the time spent to explain the project management plan from the delivery of materials to the post-installation inspection. Everyone we met was very professional and the clean up crew did a great job."

"Mr. Lee was on time, came prepared with samples of products in range of prices, left literature, walked the roof, politely offered suggestions but left final decision to us. Mr. Lee also answered all questions and returned phone calls."

"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."

Roofing questions, answered by experts

16-gauge galvanized steel staples with a minimum crown of 15/16 inches or 24 millimeters are occasionally used to install shingles. However, most shingle manufacturers or residential building codes don’t recommend staples as a roofing fastener. Roofing nails are preferred in most cases, especially in areas that get a lot of heavy wind.

A properly installed, high-quality tarp can be left on a roof for up to 90 days. However, this is only a temporary measure and not a substitute for proper roof repair or replacement. Thinner tarps or those exposed to heavy wind and rain may not last the full 90 days, so it's important to monitor the tarp's condition to ensure it continues to protect your roof from the elements.

If your roof has a vapor barrier, you will need approximately one square foot of roof vent for every 300 square feet of ceiling space. If there is no vapor barrier, the roof should have one square foot of roof vent for every 150 square feet of ceiling space. If you are not comfortable making this determination, a local roofing professional can help.

Mansard roofs provide more attic space or living space on the interior than many other styles, and they offer a classic appearance and old-world charm to any home. They also often have multiple windows on the lower hip, providing ample natural light and ventilation. 

On the other hand, they’re more expensive to install and replace due to their complexity and rarity, and the low slope of the upper hip means that heavy snowfall can be an issue. Additionally, they’re more prone to leaking than many other roof styles.

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.
