"Robert did an amazing job on my roof.   He is a very pleasant person to work with, and is very nice.  He replaced my roof very quickly.   I have had lots of comments from my neighbors about how good the roof looks.  I would recommend him to anyone else looking for a roofer. "

Roofing FAQs, answered by experts

Furring strips (also called wood stripping) are not always necessary for a metal roof installation, but they are highly recommended and may be required by local building codes or the roofing manufacturer's specifications. There are several key reasons to use them:

  • Energy Efficiency: Furring strips, made of wood or metal, create an air gap between the metal panels and the roof deck. This acts as a thermal break, reducing heat transfer into your home and improving overall energy efficiency.

  • Moisture and Condensation Control: The air gap allows for better airflow, which helps prevent moisture buildup and condensation under the metal panels.

  • Structural Support: They provide a solid, even frame to which you can attach the metal roofing panels.

It is especially important to use furring strips when installing a metal roof over existing shingles. Without them, the roof surface can be uneven, and you will experience greater solar heat gain.

It’s always a good idea to have a lawyer review any legally binding contract before signing, including roofing contracts. Most contracts have straightforward language that’s easy to understand, but getting advice from an attorney before signing could save you from being locked into a contract you don’t want to move forward with. Having a lawyer review your contract can also help protect you if your roofing professional defaults on their side of the agreement.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.
