There are many tell-tale signs that your roof could be nearing the end of its useful life. Look for any of the problems below to determine whether you should consider replacement before winter.
Ventilation is key.
Failure to adequately ventilate your attic will leave humid air from the living area trapped in the attic. Any number of costly problems can be the result.
If needed, we’ll send a certified expert to your home to measure and inspect your roof and attic to determine how much intake and exhaust ventilation is needed.
Proper airflow requires care and planning.
To move moist, humid air out of the attic, the entire interior of the attic must have continuous airflow. Without the right mix of ventilation points the air in the center of the attic will often remain static. Usually, the result is a dangerous buildup of moisture.
The stack effect is key.
To move air throughout the attic, it’s necessary to achieve a “stack” effect, in which airflow across the roof draws air up through soffit or edge vents. The air is pulled through the attic, and then flows of out the ridge vents or can vents. A balanced amount of intake and exhaust are required, as well as correct placement and proper installation of ventilation solutions.
Poor ventilation can cause moisture to build up—fast.
Bathing, cooking, doing laundry, and cleaning produce water vapor. Add the vapor produced by human, animal, and plant respiration, and a normal household puts up to 300 liters of water into the air each month (Pilon & Tenwolde 2007). Proper attic ventilation is critical in preventing moisture buildup.
Roof valley protection
Roof valleys are among the major trouble spots for leaks and eventual water damage, but with proper installation of the right products, you don’t have to worry.
Because shingles cannot lay flat across a valley, and because valleys handle more water flow than flat parts of the roof, they wear out more quickly. The only way to keep the valleys safe from eventual rot and decay is to protect them with a rust-proof metal sheet that channels water to the eaves.
We protect your roof against ice damming.
Shingles and underlayments can’t prevent leaks when water sits stagnant. During winter, water becomes trapped at the eaves, often causing considerable damage. In Michigan, ice damming damage is among the most common causes of major roofing problems. Even a single season of heavy ice buildup can ruin the wood at the eaves.
Ice and water shield is the best defense.
A water-tight layer of rubber membrane, that can keep standing water at bay is the only way to mitigate the danger posed by ice buildup.
Get a breathable underlayment.
Climate is an important consideration when choosing an underlayment. If snow and ice will cover vents, the wise move is a breathable underlayment. Common synthetic underlayments are excellent at preventing leaks and are intended to provided a second line of defense in the event that shingles are torn free during a hurricane. However, these materials also trap moisture in the attic. If the primary ventilation isn’t working, the result can be wood delamination, mold, and wet insulation.
We use Gorilla Guard® engineered felt underlayment, which is uniquley cost-effective for climates like ours. To get the benefits of typical synthetics, plus the breathability of feltpaper, a breathable synthetic underlayment (GAF® Deck Armor) is also available.
We use high-tech shingles
We offer Atlas® shingles with Scotchgard® protection, so your roof will both look and perform like new even after years of punishing ice, snow, and hail. And because Atlas® offers a wide variety of shingle colors and styles, we can help you make a selection that’s just right for your home.
Shingles fail when granule loss exposes the asphalt to the sun. When the asphalt cracks, the matt is unprotected and rapidly deteriorates. Atlas® Stormmaster incorporates SBS rubber to reduce granule loss by 90%, and usually reduces insurance costs because it is hail resistant.
Industry-best algae resistance
Atlas® shingles include far more algae-resistant copper-coated granules than competing algae-resistant shingles. Preventing algae and lichen growth (see Figure 6) helps to further prevent catastrophic granule loss.
Chimney Saddles & Flashing
Saddles prevent ice buildup.
Without a saddle, many chimneys retain snow which turns to ice over time. When heat from inside the home melts the ice from below, water may sit stagnant on the roof, causing leaks and rot. If needed, we’ll build a chimney saddle to both provide a runoff path for melting ice and limit snow buildup.
Sun-exposed sealants fail.
Even the toughest sealants will last only a short time when exposed to direct sunlight year-round, in combination with seasonal temperature extremes. To protect the sealant from sun exposure, we cut a groove into the mortar and tuck the edge of the flashing inside. This way, the flashing sealant lasts as long as the roof.
We recycle project waste.
When we haul away your old shingles, they aren’t going to a landfill. They’ll be turned back into raw asphalt, to be used to resurface roads.
We provide meaningful warranty coverage.
Typical shingle warranties provide little peace of mind due to fine print exclusions and aggressively prorated coverage. WeatherGard® and Atlas® provide real coverage.
Lifetime protection against algae growth. Standard shingle warranties prorate or limit coverage of the shingles against algae growth and resulting wear and discoloration. Atlas® Scotchgard®-protected shingles are covered for life against all four strains of algae growth (covering both patch growth and streaking).
Lifetime protection against shingle defects. If your shingles fail prematurely due to any manufacturing defect, Atlas® will cover against the cost of replacement shingles.
Coverage for both labor and materials. Unlike standard manufacturer’s shingle warranties, if the homeowner chooses to have WeatherGard-recommended roofing products from Atlas® Roofing installed, we’ll provide a guaranty on workmanship, good for the life of the roof.1
 Some product selections are excluded. A WeatherGard-recommended underlayment and shingle solution are required. Depending upon underlayment and shingle selection, workmanship may be guaranteed from 5 to 15 years.
