Roofing questions, 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.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

The placement of snow guards depends on the individual roof, but typically snow guards are placed between 12 and 18 inches from the eaves, though they can be placed as close as six inches and as far as 24 inches from the eaves. A roofing professional can assess the roof and potential snow loads to determine the best placement.

Manufacturers, insurance companies, and municipality regulations are phasing out three-tab shingles. Because of their short lifespan and lack of durability compared to other roofing material types, manufacturers are leaning toward better products, and cities and insurers are starting to require better building materials overall. However, 3-tab shingles are still for sale, and some roofing companies still install them.

In general, you should consider replacing your roof if more than 30% of it is damaged. This includes several missing shingles, large spots of granule loss, extreme curling or cracking, structural damage to the roof's decking, or multiple areas of leaks. All of these issues could indicate compromised structural integrity that requires roof replacement.
