"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. "

"Chris was very motivated and started the job promptly. His work ethic was great, staying late a couple of days late to complete job on time as agreed. He reviewed any issue found and was flexible when extra work was needed. The quality of the work was great in making the breezeway siding look the same as the garage, so with the paint job the house/garage improvement was dramatic. His pricing was reasonably and his clean-up appreciated. We would definitely recommend Chris to others and would engage him for work ourselves."

Roofing FAQs, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

You’re going to need a permit for nearly every roof-raising project. This is a very important step, as the work you’re doing has serious safety considerations. Professionals are the ones to handle this type of work—including sourcing the permits—as they have the expertise required to perform the work safely. Insurance and warranty are usually voided if you do this work without a permit, and you may even be required to halt construction and tear it down as a penalty for working without a building permit.

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.

The terms “roof shingles” and “roof tiles” are sometimes used interchangeably, but the term “shingles” most often refers to asphalt, rubber, metal, or slate shingles, and the term “tiles” normally means they’re made from clay or concrete. In all cases, shingles are small, rectangular components that a roofer layers in an overlapping pattern to protect the structure underneath from the elements.

Roof blistering and hail damage are different in their physical appearance. Blistering, often caused by inadequate ventilation, low-quality material, and improper installation, looks like large, irregular bubbles popping out of your roof. Meanwhile, hail damage is usually circular or oval dents entering your roof and often follows the same path as the hail storm.
