"This company was great. They got back to us right away for an estimate and a start date. We had to postpone a week due to rain but Richard contacted us in a timely manner to let us know when the new start date would be. The crew came on time, were very nice, did the work quickly and professionally and cleaned everything up. Richard came by every day to check on it all. We are very pleased with our new roof, patio cover and the whole process."

"They were kind and efficient. I had to be diligent and push them to do a water test of the roof or else they would have diagnosed it with the wrong issue. But other than that, they were able to perform the work and solve the issue. It ended up needing a flashing maintenance rather than to re-do a whole portion of my roof (big difference... $1,500 vs. $4,500)"

Roofing FAQs, answered by experts

No, a metal roof will not make your house hot. In fact, metal roofs help keep your home cooler by reflecting heat instead of absorbing and transmitting it inside. Metal also has high thermal conductivity, which means it gains and loses heat quickly. While the sun may heat the metal, the roof rapidly transfers that heat back into the air rather than retaining it. This reflective property can lead to energy cost savings of up to 40%, as your cooling system won't need to work as hard to maintain a consistent indoor temperature.

Whether or not the terms of your roofing estimate are negotiable depends on the contractor. Some professional roofers will be willing to budge on labor fees to some extent, while others will simply walk away from the potential work rather than lower their fees. In most cases, it’s best not to negotiate the terms, as lower labor charges could lead to your contractor cutting corners. Material costs aren’t negotiable, but you could purchase them yourself to try to save on delivery fees and markups.

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.

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. 

You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.
