Roofing questions, answered by experts

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.

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.

Complete house winterization goes above and beyond the list we created above. In addition to everything listed, full house winterization also includes:

  • Performing a home energy audit.

  • Preparing your deck and patio for winter.

  • Learning how to start a snowblower.

  • Replacing smoke detector batteries.

  • Installing outlet gaskets.

  • Installing storm doors.  

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.

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.
