"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

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.

The roof overhang, also known as the eaves, does count as part of the roof’s square footage because it must be covered with the roofing material. The overhang is one of the reasons why you can’t base your roof's square footage on the square footage of the house. The roof square footage must also account for the pitch of the roof as well as the eaves.

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.
