Are heavier shingles always better quality?
Shingles with longer warranties tend to be heavier than shingles with shorter warranties. Weight is not the only measure of shingle quality. Asphalt and shingle tear strength are also important indicators of shingle performance.
One of the heaviest asphalt type shingles in the marketplace is the Certainteed Grand Manor shingle. This is an extremely durable product, with a lifetime warranty, but not simply because of its weight. Each Grand Manor shingle is comprised of two full base shingles, which results in no less than four full layers of shingles over the entire roof. Grand Manor contains more than twice the amount of rough, tear-resistant material compared to standard shingles, plus randomly applied laminated tabs for added dimensionality.
Is ventilation really that important?
Ventilation is a system of intake and exhaust that creates air flow. Effective attic ventilation provides year-round benefits, creating cooler attics in the summer and drier attics in the winter, protecting against damage to materials and structure, and helping to reduce energy consumption. With poor ventilation, the summer heat can increase the temperature in the attic by as much as 50 degrees higher than the outside ambient air temperature. If an unventilated attic is heavily insulated, that heat will stay in there much of the night, perhaps slowly migrating to the home’s interior. An over-heated attic, combined with moisture, can also be damaging to roof decking and roofing shingles, causing them to distort and deteriorate prematurely.
In the winter, a house with poor ventilation, warm, moist air from the lower portions of the home will tend to rise through the ceiling area into the attic, especially through bypasses where electrical and plumbing fixtures are installed. In a cold attic, the warm, moist air condenses on the cold surfaces of the rafters, nails and other metal, and the attic side of the deck. This water can create several problems. First, the condensation can swell the deck, causing waviness and buckling of both the deck and the shingles. Second, the water can rot the roof deck, destroying its ability to carry loads and its nail-holding capability. Third, severe condensation can drip onto the insulation, reducing its effectiveness and possibly seeping through the ceiling below.
What is external fire resistance?
The required degree of external fire resistance is usually established by local building codes and/or insurance companies. Asphalt roofing shingles are manufactured to meet either UL Class A or Class C fire ratings. Shingle manufacturers submit to Underwriters Laboratories Inc., where the shingles are subjected to testing in accordance with UL 790 Fire Resistance standards. Shingle fire resistance performance is judged on the flame, and ignition due to burning brands on the top surface of the shingle roof.
What is tear resistance?
The best way to compare the “toughness” of shingles is to look at tear resistance. Read manufacturers’ shingle audit reports or other reports published by independent testing services. The industry-accepted method used for comparing shingle toughness is tear resistance as defined by the American Society for Testing and Materials (ASTM). This method is part of the ASTM D462 performance standards for fiber glass shingles. It requires that a shingle resist a minimum of 1700 grams of force on a pendulum type tear tester.
What is underlayment and why is it required?
Underlayment is an important component in the UL fire resistance classification. It can provide back-up protection in case of a shingle blow-off, and during the installation of the shingles it can keep the unshingled decking dry.
What could be causing algae, moss or lichens to grow on my roof?
Keep the roof clear of debris, such as leaves and pine needles, and keep tree limbs cut back from the roof. Some trees produce sap and will naturally drop some of the sap onto a roof when in close proximity to a home. Tree sap contains nutrients and sugars that are considered fine dining for algae, moss and lichens. Sap from trees on a shaded roof area can accelerate micro-organism growth versus a roof not influenced by trees. Trees on a roof surface and, depending on the size and type of trees, may inhibit air flow across the roof. This combined with dropped leaves and debris makes a perfect environment for algae, moss, or lichen growth.
Home Improvement stores carry cheap shingles. What’s the difference?
Low budget shingles can, and often do, present a lot of problems. For example, they might have coloring that doesn’t quite match from bundle to bundle, a shingle length that is out of “spec,” not enough asphalt used when the shingle was made, a weak fiberglass mat, and so on. These types of defects can lead to roofing problems that range from poor appearance and a short life-span to a high risk blow-off.
