"This is the second time we use Richard and his team at Federal Building & Roofing, and they have been excellent. This time, due to the many homes with roof damage from the heavy winds/rain, it took a bit longer to schedule, but he got it done on a Saturday, and right in time before more rain. Professional, Good Quality Work and Dependable."

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

"All went well, roof looks great! People walked in the neighborhood and would comment that the progress was looking good. I picked Hoyt out for 4 bids. The city inspector said when I asked him if they did a good job, he said yes and he would recommend them."

Roofing questions, answered by experts

Hiring a reliable roofing contractor requires finding a company in your area with years of experience, holds the necessary licensing, and has a history of positive customer reviews and services. Start by researching whether a roofer you’re considering hiring holds the necessary certifications. Consider requesting customer references from your top contenders. Finally, get quotes from a few roofing companies and decide which provides the best value overall.

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.

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.

If you’re choosing between a roof overlay and a tear-off, opt for a tear-off and full roof replacement instead of a roof overlay if possible. The cost savings from an overlay can easily be eclipsed by repair costs, the effects of structural damage from the additional weight, and needing to replace your roof sooner than expected. A full replacement will last longer and is less likely to need damage repaired over time.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best.
