"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."

Roofing questions, answered by experts

Building an A-frame roof falls under the category of constructing a steep roof. While its structure is relatively simple, its height and requirements for more materials than a shallow roof design can increase its cost significantly. Expect prices for building an A-frame roof to hover around average to slightly above average.

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.

Homeowners insurance may cover the cost to tarp a roof if the type of damage falls within your coverage. For example, roof damage caused by a natural disaster may fall within your plan, and the cost of a temporary tarp may be incorporated. In general, however, simply tarping your roof for renovations will often not fall under insurance coverage.

A standard roof can hold a live load of about 20 pounds per square foot. However, gable roofs often have steeper-than-average slopes, so calculating their weight capacity can be challenging. If the slope of your gable roof is greater than 4:12, the live load needs to be decreased to allow for a larger dead load. Ask your roofer exactly how much weight your roof can support.

Yes, an underlayment is required for metal roofs, especially when installed over an indoor residential living space. This underlayment acts as a protective barrier between the metal roofing and the roof deck. Common materials include tar, asphalt felt, or woven synthetic polymers. Depending on local building codes, existing shingles in good condition may also suffice. A quality underlayment is crucial as it provides protection against water intrusion, improves energy efficiency through insulation, helps absorb sound, and ultimately extends the lifespan of your roof.
