The longevity of shingles

Taylor Quinlan • Jun 13, 2022

How long should my shingle last, and what causes them to wear?

HOW LONG SHOULD MY SHINGLE LAST?

 

This is perhaps, the most common and the most important question one might ask when looking for a new roof, getting a new roof, or just having installed a new roof. Like most things, the answer is: IT ALL DEPENDS!

 

VARIABLES AFFECTING LONGEVITY OF SHINGLE LIFE:

Minnesota, and other northern states in general that have extreme winter weather conditions, have many weather-related factors that can negatively impact one of your home’s most important components. Let us briefly discuss the big ones here:

INSULATION:

           One of the benefits of insulation is to prevent the movement of air, mainly the movement of the warm air within your livable spaces to the colder outside air that exists in your attic. Warm air inside of attics creates frost in the wintertime which deteriorates your roof sheathing at a much faster rate. This deterioration can negatively affect your shingles over time.

VENTILATION:

           A vital component of any roof system, ventilation allows any warm (moist) air to escape the attic cavity thereby reducing the likelihood that frost can build up. Additionally, in the summertime, good ventilation can exhaust the warm air that builds up from the heat of the sun. In both instances, adequate ventilation immensely reduces the temperature swings within your attic and in so doing increases the life expectancy of your shingles.

 

 

ORIENTATION TO THE SUN:

           Believe it or not, a shingle that prominently faces East-West will have a longer life expectancy than a shingle that faces North-South. The sun’s powerful rays deteriorate anything that it shines directly onto, and an asphalt roof is no exception. Additionally, the north side of roofs, which see limited sunlight has a greater likelihood of moss/algae growth which can cause damage to the granules integral to any shingle.

QUALITY INSTALLATION:

           As with anything if it is not done right upon installation, then it cannot be expected to last as long as it otherwise would. Diligence to items such as flashing work, roof penetrations, and nailing can all affect longevity.

SURROUNDING VEGETATION:

           Tree cover, lakes/rivers, or wide-open spaces around one’s home can affect the longevity of the shingles. Trees drop leaves, twigs, and sometimes limbs on our rooftops which over time can have a negative effect on longevity. Excessive moisture levels associated with bodies of water can affect longevity through an increase in mold/mildew and algae/moss growth. As well as wind can play a significant role in the likelihood of “blow-off” of your shingles or other components.



               All these factors can be mitigated with knowledge of their existence and a good game plan on how to deal with them. At TCR we have a working knowledge of these factors and take them into account with any re-roofing project.

Once again, the days are getting shorter, the wind is getting colder, the air is getting crisper, and you still haven’t prepped your home for winter. Before you know it, snow will be billowing over your house, icicles will be hanging from your eaves, and frost will be building on your windows. Don’t panic. Prepping your home for winter may be easier than you think with a little help from your friends at Twin City Roofing (TCR). Here, you’ll attain helpful TCR Tips to spot areas susceptible to damage, learn practical tips to help winterize your home, and gain valuable insights into better understanding the importance of adequate insulation for the performance of your home during Minnesota’s harsh winter season. WARNING SIGNS TO LOOK FOR As the rusty colors of fall begin to change to the white of winter, does your home feel a bit drafty? Does your home show deteriorating door seals, weathered windows, worn-out weatherstripping, and corroded caulking details? If so, your home might be showing warning signs that it’s inadequately prepared for winter. Don’t worry, it’s not too late to make some short-term, inexpensive improvements to prep your home for winter. Indeed, several areas that are prone to winter damage include doors, windows, or outlets located on your exterior walls. To inspect your home for the winter season, check out TCR’s practical tips below. PRACTICAL TCR TIPS TO PREP YOUR HOME FOR WINTER With winter right around the corner, a few practical inspection tips you should consider using revolve around examining drafts, spotting issues on your roofing system, and recognizing condensation possibly forming inside your home. Examine Areas Prone to Drafts · Check for gaps and crack under and around windows and doors · Check for condensation forming on the glass of windows and doors · Feel for cold spots on walls, cupboards, and on the floor Inspect your Roof · Look for “hot spots” on your roof where the frost melts in some areas and remains thick and frosty on adjacent spots Ice Formation · Look for ice crystals or frost forming on the inside of your home in unusual places, such as on the surface wood materials in attic spaces, storage spaces, recessed closets, and the inside of knee-walls · Look for sudden stains in areas that you hadn’t noticed during the rainy season To ensure your home’s safety for winter, remember to check the function of your home’s exterior doors to make sure that everything works properly and there are no signs of warping or excessive gaps. Next, check your home’s window operation status for proper opening, closing, and locking functionality. Lastly, inspect your home’s doors and siding fixtures, such as lights and outlets, for missing parts, holes, or poorly caulked areas. AFTER INSPECTION: SIMPLE WAYS TO PREPARE YOUR HOME FOR WINTER Here are some simple steps that you can take to prepare your home for winter. Seal Window and Doorframe Gaps If your windows are drafty and replacing them completely is unfeasible, simply cover them with plastic wrap that Big Box stores sell annually, which will aid in decreasing both your drafts and heating costs. Consider sealing other gaps in your window and doorframes with spray foam insulation, applying fresh caulk to the outside of these frames, replacing the weatherstripping on your exterior doors and windows, and checking the seal strips in these areas. If you notice gaps near the bottom of outside door, simply use a rolled-up rug to plug the gap or an insulated door sweep to fix this problem. Clear Out Gutters and Downspouts Be sure to inspect and clean your gutters and downspouts for gathering debris that could lead to draining issues. Inspect your Siding and Roofing Systems Check your siding systems for signs of cracks, voids, or missing parts that could lead to additional damage. Next, check your roofing system for missing shingles, adequate ventilation, and updated flashing and caulking details. Don’t forget to check your attic spaces for insulation voids as well. Check your Soffit System Finally, check your soffit system for clogged intake vents, painted-over vents, or worn-out vents. Now that you understand how to adequately prepare your home for winter, have you considered the importance of insulation in your home as a Minnesotan? You might have a general idea of what household insulation is, but why is it important to know specifically as a Minnesotan? These are all great questions that will be answered below. THE IMPORTANCE OF INSULATION IN MINNESOTA Winters in Minnesota are brutal. The extreme cold, snowstorms, ice storms, sleet, and strong winds are ruthless compared to other states that have winter. As a result, the need for insulation is heightened for Minnesotans. Indeed, a few reasons why insulation is so imperative in Minnesota is that it reduces heat loss, helps prevent ice damming, stops moisture buildup on roofs, and reduces energy costs. Reduction of Heat Loss First, installing insulation in your Minnesotan home for winter will reduce heat loss by decelerating the rate of heat flow throughout your home. Simply put, insulation keeps the heat inside your home, preventing it from escaping and being wasted out in the bitter cold. With the reduction of heat loss, sufficient insulation, coupled with adequate eave and roof ventilation, decreases the formation of ice dams by maintaining an even underlying roof surface temperature, which also improves water run-off. Reduction of Moisture Formation  In addition, insulation can stop moisture from building up on your roof by keeping the base of your roof at a higher temperature than the air outside. The result of this procedure is a minimization of the formation of condensation, helping protect your home even more from winter. Reduction of Energy Costs Lastly, insulating your home can reduce your energy costs, as any leaks in your home near your windows, doors, and any additional openings utilizes a significant amount of energy and can lead to an unwanted spike in your utility bills. To avoid these unwanted expenses, simply remember to properly insulate your home and you will be on your way to saving both energy and money. TAKE ACTION AND START PREPARING YOUR HOME FOR WINTER NOW By keeping an eye out for warning signs, implementing the practical winter tips, learning about the ways you can prepare your home for winter, and understanding the importance of insulation in Minnesota, you will be on your way to protecting your home from the harsh conditions in winter.

Asphalt shingles are installed using pneumatic nail guns that shoot coil roofing nails through the shingle and into the sheathing or deck boards underneath. If you have sheathing, OSB or plywood, you more than likely will not have to install any new sheathing unless the OSB or plywood is in bad condition. The need to “Re-Deck” usually comes into play when deck boards are what make up your roof deck. The problem lies in the “gapping” between those boards, as seen below:

Attic bypasses are places in the attic where indoor air leaks up, mixing with the outdoor air that is in the attic space. These leaks allow warm air to mix with cold air in the wintertime and cooler air (air conditioning) to mix with warmer air in the summertime. When this interaction is allowed to continue overtime, the results can lead to deterioration of your roofing components such as framing, sheathing and shingles. In the wintertime, especially, this interaction can cause the most damage in the form of ice dams, condensation (see previous blog) which lead to leaking ceilings. Sealing of attic bypasses ( as well as other common areas of air leaks ) can greatly increase the efficiency of your homes HVAC equipment, increase the longevity of your exterior components and create a more comfortable living space within the home. On average, it is said that the average home leaks enough air as leaving a window wide open all year long!
