Of all parts of your home, your roof takes the most beating. It protects you and your family against rain, sunlight, snow, hail, and all sorts of harsh outdoor elements. Soon enough, it will give in to regular wear and tear, and without proper roof maintenance, you’re looking at thousands of dollars in roofing repair.
But here’s the good news: there are ways to protect your home’s number one protector. In this post, we discussed the importance of roof maintenance, signs of damage, and how you can prevent them from getting worse. Keep reading because your roof might have these silent problems that won’t be easily visible unless it’s too late!
Why is roof maintenance important?
With a challenging climate like that of Minnesota, roof maintenance is crucial, especially before wintertime. Regardless of the season, staying on top of your roof’s condition is crucial to avoid inconvenient and expensive surprises later on.
Whether you’re in Minnesota or any other state, here are reasons why you should practice regular roof maintenance:
- It prevents costly repairs. Being proactive with your roof’s condition will save you from costly and repetitive repairs down the line. For example, moss buildup may not seem like an emergency, but if left unchecked, it will hold moisture and cause significant portions of your shingles to rot.
- It extends your roof’s lifespan. Most roofing systems can last for 20 to 50 years. However, without regular maintenance, you’ll start experiencing leaks, curling, granule loss, and other issues within 15 years after installation. This could spell expensive repairs or even a full roof replacement.
- It prevents structural damage. Take note that any damage on your roof can trickle down to other parts of your home. For example, water leaks will corrode metal roof frames or rot timber frames. Over time, this will weaken your home’s structure, which, again, will be costly to repair.
- It enhances curb appeal. Poorly maintained roofs will make your home look worn out, a big problem if you’re planning to sell your property soon.
- It’s a matter of safety. Roof damage, such as leaks, can trigger electrical hazards, mold and mildew, and even the risk of structural collapse. Falling debris, such as loose shingles, can also harm you or anyone below.
Early warning signs of roof damage
Spotting early signs of roof damage is the first step in preventing expensive repairs. Take note that not all roof problems aren’t always obvious, so make sure you check for the following signs:
1. Shingle issues
If you have a shingle roof, you should check for curling, cracking, or missing tiles. All these will make your roof vulnerable to water infiltration, especially during the winter season. Here’s why these are serious roof issues:
- Cracked shingles. This often occurs due to weathering, which can lead to leaks and insect pest infestations if not addressed.
- Curled shingles. This means that your roofing material has reached the end of its lifespan. Curled shingles can’t protect your home properly during windstorms, heavy rains, or snowfall.
- Missing shingle tiles. This is a common scenario after a storm, where shingle tiles have been peeled off. It leaves the underlayment exposed to elements, which will lead to leaks.
2. Leaks or water stains
Are there unusual dark streaks or stains on your ceiling? This is a hallmark sign of a roof leak, and it often goes beyond interior ceiling stains. Roof leaks trap moisture in your attic, allowing mold, mildew, and pests to thrive.
Here are the most leak-prone parts of your roof and how to check for moisture buildup:
- Flashing leaks. Flashing is a metal strip that seals the joints and penetrations of your roof. It can rust, crack, or become loose, causing water stains on your attic or ceiling.
- Skylight leaks. The seals of your skylight window will eventually degrade, or the flashing around it may become damaged. When this happens, you’ll notice dampness around the skylight frame or dripping water during a downpour.
- Valley leaks. Valleys are the areas where the two slopes of your roof meet. Water runoff is very concentrated here, and if the shingles or flashing gets damaged, it can cause major leaks.
- Vent pipe leaks. The openings on your vent pipes have sealed collars, which can crack or shift at some point. Check this area for any sign of dampness or water stains, or test it by spraying water around the pipe base.
- Gutter backup leaks. Fallen leaves, twigs, and debris can accumulate in your gutters, causing clogs. This will cause rainwater to overflow from your roof and seep under the shingles or fascia boards.
- Chimney leaks. The flashing or mortar of your chimney can crack or separate, letting in water at roof junctions. If you can see damage on the chimney bricks or mortar, consider getting it tested for leaks.
3. Moss and algae growth
Moss and algae growth may seem like a cosmetic issue, but it actually holds moisture and keeps areas of your roof damp, leading to shingle damage and decay. If not removed, continued moss growth will lift the edge of the shingles, allowing water to seep into your attic.
In the long run, moss and algae growth will speed up your roof’s aging. Thick moss will also add extra weight to your roof, which can become a structural problem, especially when paired with snow buildup in winter.
Causes of moss growth on roofs
Almost all causes of moss growth on roofs are preventable. Unfortunately, many homeowners tend to overlook them, thinking they are natural and innocent. So, if you’re noticing moss growth on your roof, here are the main culprits:
- Shade and moisture retention. Moss thrives in damp areas with no direct sunlight. This is why overhanging trees combined with moisture fuel the growth of moss and algae. You should also look for nearby structures that block sunlight as well as organic debris left sitting on your roof.
- Poor drainage. Clogged gutters and pooling water provide the moisture that moss and algae need to proliferate on your roof. This happens due to debris buildup, ice dams, or poor slopes that block proper water runoff.
- Aging roof materials. Weakened roof surfaces provide a foothold for moss and algae. Older shingles will start to lose their protective coating and granules, leading to moisture retention. Aging shingles also become more porous, which means they tend to absorb moisture.
Effective methods to prevent moss growth
There are many easy ways to prevent roof moss from wreaking havoc on your home. Here are some ways to remove moss on your proof and keep it off:
Keep gutters and roof clean
Start by cleaning up any debris or leaves that could clog your gutters or harbor moisture on your roof. Use a ladder to climb your roof, and wear gloves to scoop any debris.
Pro tip: To avoid repetitive cleaning, you can install gutter guards that block large debris from entering your gutters. Reach out to us at Boelter Is Better to learn how!
Trim overhanging tree branches
To prevent moss buildup, you’d want your entire roof to be exposed to sunlight. This will dry up any trapped moisture and prevent leaves from clogging your gutters.
Simply prune all tree branches and vegetation that shade any portion of your roof. And while you’re at it, trim any foliage that’s touching your roof, as this can be a pathway for critter pests!
Install zinc or copper strips
Zinc and copper strips are natural moss inhibitors. They are installed near the ridge of your roof and produce metal ions when exposed to rainwater. These ions are toxic to moss and algae, preventing them from growing on your roof. But don’t worry – only a small amount of metal ions is released, and it’s totally safe for wildlife and humans.
Make sure that you use strips that run the full length of your roof for proper coverage. Still, leave a small gap between the zinc or copper strips and shingles to avoid rusting or staining.
Improve roof ventilation
Improving your roof’s ventilation allows warm, moist air in your attic to escape. This way, you can avoid moisture buildup on the roof’s surface and underlayment, where moss and algae could form.
And in case condensation forms on your roof, it will dry up faster with proper ventilation. This removes any chance for moss to grow, as moisture dissipates quickly.
Apply moss prevention treatments
If moss keeps recurring on your roof after repetitive removal, it might be time to consider chemical treatments.
For starters, you can try over-the-counter moss-killing sprays available at hardware stores. If you want a more natural and safer solution, you can use an equal mixture of vinegar, bleach, and water. You can also sprinkle baking soda on the mossy areas to stop its growth and spread.
However, for extensive moss growth, you may need professional-grade treatments. For this, you need to hire a roof cleaning service that uses solutions such as zinc sulfate, copper sulfate, and other chemicals.
4. Granules in gutters
Asphalt shingles come with granule coatings that act as a protective layer against outdoor elements. However, these granules will soon become damaged, which will eventually come loose and get washed down into your gutters.
If you see an accumulation of sand-like or gravel pieces in your gutter, this is possibly a sign of granule loss on your shingles. Note that granule loss worsens over time, so it’s essential to repair or replace any damaged shingles promptly.
5. Sagging roof sections
Are you seeing visible dips and uneven areas on your roof surface? Or do you see your roof deck bowing or bending downward? These are signs that your roof is sagging, which can pose a serious structural issue if not fixed right away.
Roof sagging is a significant problem for several reasons. First, water will pool on sagging parts, which could cause cracking on your interior walls or ceiling. During heavy snowfall, the bowed rafters may give in under load.
6. Higher energy bills
Poor insulation from roof gaps and air leaks will force your heating and cooling to compensate just to maintain a comfortable indoor temperature. The result? A sudden spike on your utility bills!
Overall, a damaged roof disrupts your attic ventilation, allows drafts, and even lets more sunlight and heat into your home. If not addressed, you’ll be facing a much bigger expense once it’s time to get a full roof replacement.
7. Damaged flashing
Roof flashings act as a water barrier on roof joints, penetrations, and other vulnerable spots where water leaks could occur. However, flashings can crack, rust, or become loose – early warning signs that your roof may face bigger issues in the future.
If not repaired or replaced, damaged flashing will let water in, harboring moisture and causing a slew of other roofing problems.
Common causes of roof damage
While roofs aren’t meant to last forever, some elements contribute to premature damage. Below are the four main causes of roof damage in Minnesota:
Weather exposure
A majority of roof damage is due to weather-related events. This includes rain, strong winds, hail, heavy snow, tornadoes, and other severe weather conditions. These elements cause significant wear and tear on your roof, ultimately leading to structural damage over time.
Poor installation
Poorly installed roofing often includes misaligned shingles, incorrect flashing installation, improper underlayment, inadequate sealing, and a long list of other issues. All these will expose roof materials to unnecessary weathering, leading to premature and expensive damages.
Aging materials
Your roof materials are bound to age and become damaged. Shingles will lose their protective granules, materials will become brittle, and the roofing system will become structurally weak. And as your roof gets older, it becomes less efficient in withstanding harsh elements.
Lack of regular maintenance
While roofs are designed to withstand harsh conditions, they still require proper care to prevent damage. Without maintenance, moisture-absorbing debris will pile up, gutters will get clogged, and rot will set in. Before you know it, you’re due for expensive repairs or roof replacement way earlier than the roof’s expected lifespan.
How to prevent roof damage
Many causes of roof damage are preventable with proper maintenance. To ensure that your roof is ready to protect you in every season, you must perform these preventive steps:
1. Inspect your roof every season
Regular inspections will allow you to catch early signs of damage before it takes hold of your roof. Consider doing this before the start of every season, especially winter, to ensure that your roof is ready for the harsh weather conditions.
When inspecting your roof, look for damaged shingles, debris buildup on valleys, cracks in the sealing, and any signs of sagging.
But take note that some signs of roof damage can be hidden from plain sight. This is why you should consider getting annual roof inspections where a licensed roof technician will conduct a comprehensive check of your roof system.
2. Inspect your gutters and downspouts
Clogged downspouts and gutters will allow rainwater to pool or overflow from your roof. As we’ve mentioned earlier, this trapped moisture is the main culprit in roof damage.
First, do a visual check for any visible debris, sagging parts, loose sections, and separation from the roof edge or fascia. Also, look for stains, mold, or rot on soffits, which may indicate roof leaks.
3. Prune overhanging branches
Trees provide shade, but it’s not something you’d want on your roof. Lack of direct sunlight allows moss, algae, and mold to grow on your roof, which can lead to early damage and leaks.
Overall, make sure that you trim any overhanging branches that could drop leaves and clog gutters.
Aside from preventing trapped moisture, pruning overhanging vegetation on your roof will also prevent pests from accessing your home. It will also prevent storm damage when branches break off and fall into your roof (or someone else’s!) due to strong winds.
4. Be proactive with minor damage
Small cracks, loose shingles, or popped fasteners may seem like minor issues, but they can eventually lead to serious damage if not addressed promptly.
Stopping small issues from worsening will save you from a lot of inconvenience and expensive repairs in the future. It will also extend your roof’s lifespan while keeping you and your family safe.
5. Prevent debris buildup
Clean your roof at least twice a year, ideally in spring or fall, to prepare it for the intense weather. You can use roof rakes to remove debris and soft brushes to scrub off moss without damaging the shingles.
Aside from that, you can install gutter guards and leaf diverters to direct debris off your downspouts or roof valleys.
6. Replace damaged shingles
For localized and minor damage, you can replace several shingle tiles to prevent the issue from spreading on your roof. This will prevent leaks and maintain the integrity of your roofing system.
However, if the shingle damage is already widespread and your roof is nearing the end of its expected lifespan, you should consider a roof replacement instead.
7. Look at chimneys, skylights, and vents
Chimneys, skylights, and vents are some of the most vulnerable areas of your roof. These roof penetrations are prone to leaks, which can compromise the entire roof if not properly maintained.
For this, check and replace sealants if there are any signs of damage. Also, inspect for signs of moisture and structural issues that could worsen later on.
8. Check for signs of wildlife
Animals like birds, squirrels, raccoons, and rodents can leave significant damage to your roof. They can chew through shingles, insulation, and wood rafters, which will weaken your entire roof.
Aside from that, birds nesting on gutters, attic spaces, or vents will block proper ventilation. This will cause moisture buildup and pose a fire hazard to your home.
If you notice signs of wildlife on your roof or attic, contact an animal control service to address the situation properly.
9. Check caulk and flashing
Over time, your roof’s caulk and flashing will get brittle and damaged. When this happens, water and debris will start to seep in, creating a long list of roof problems.
You should look for any cracks, peeling, gaps, or missing caulk around roof joints and penetrations. If you notice any loose flashing, tighten it to prevent leaks.
10. Remove molds and algae
You should remove molds and algae as soon as you notice them on your roof. For this, you can use over-the-counter roof cleaners or a homemade mixture of vinegar, water, and bleach to kill mold and algae spores.
Also, avoid applying cleaning solutions in direct sunlight, as they may cause stains on your roof.
11. Seal your roof
Sealing your roof adds another layer of protection against outdoor elements. This is often done by licensed roofers, like Boelter Is Better, to ensure the quality and effectiveness of the seal.
For this, we will use a compatible sealant that matches your roofing material, which may be an acrylic, elastomeric, or silicone product. Depending on how much wear and tear your roof gets, resealing is recommended every 3 to 10 years.
12. Check your attic regularly
Make it a habit to inspect your attic for water leaks, mold and mildew, wildlife, and other signs of damage. You should also examine the insulation’s condition to ensure that there are no compressions or gaps.
Always enter your attic with proper lighting to avoid injuries or missing signs of damage. Note that attic checks are crucial for detecting roof damage, so consider doing them twice a year.
13. Prevent ice dams
Ice dams are ridges of ice that form near the eaves, preventing melting snow from draining off your roof. When this happens, moisture gets trapped on your roof’s surface, leading to leaks, mold growth, and structural damage.
Ice dams are a common problem during Minnesota winters. It occurs when warm air escaping from your attic melts the snow on the roof, but as the water reaches the eaves, it freezes again and forms an ice dam.
Causes of ice dams
- Uneven roof temperatures. When parts of your roof are warmer than other spots, snow will melt unevenly. The melted stone will then run down to colder roof edges, where it will re-freeze and become an ice dam.
- Poor attic insulation. Damaged, old, or compressed insulation will allow heat to escape from your attic. As heat escapes, it melts the ice right where the drafts occur.
- Inadequate ventilation. Without proper ventilation, warm air will be trapped unevenly in certain areas of your attic. This increases snowmelt and the likelihood of ice dams forming.
- Heavy snow accumulation. Here in Minnesota, we can get as much as 30 to 70 inches of snow each winter. As snow piles up on your roof, it traps heat underneath, causing the snow to melt and re-freeze repeatedly, creating an endless cycle of ice dams.
Signs of ice dams on your roof
Due to thick snow accumulation during winter, it can be difficult to see whether there are ice dams on your roof. So, how will you know if you have this problem? Here are some of the tell-tale signs:
- Large icicles form along the roofline. If there are large icicles hanging on your eaves or gutters, it’s likely that there are ice dams on your roof. It simply means that melted snow is re-freezing on the edge of your roof before it drains.
- Water stains on ceilings or walls. When an ice dam forms, it can trap water underneath, which will get under the shingles and into your roof deck and insulation. This seepage will create irregular stain patches or spots on your upper walls or ceilings.
- Peeling paint or interior mold growth. As leaks from ice dams reach your interior walls, it will cause paint to bubble, blister, or peel away. You’ll typically notice peeling and mold growth near your roof edges, around windows, and walls close to the attic.
- Warped or damaged shingles. Due to the repetitive freeze-thaw cycles ice dams cause, your roof’s shingles will start to crack, warp, or lift. If not addressed, this problem will cause further leaks on your roof.
Preventive measures to stop ice dams
Taking preventive measures before winter will save you from the headache and repair costs ice dams bring. Here’s a quick checklist to help you prepare before the next cold season:
1. Improve attic insulation
Get your attic insulation checked to reduce heat transfer to your roof. You should also consider adding insulation to your attic floor to prevent warm air from escaping, especially around vents, recessed lighting, or chimneys.
2. Enhance roof ventilation
Proper ventilation is crucial in maintaining a consistent temperature on your attic and roof. This will allow ice to melt throughout your roof instead of re-freezing before it runs off.
Installing soffit and ridge vents will add airflow underneath your roof, allowing warm air to escape.
3. Use roof rakes to clear snow
Heavy snow buildup not only increases the risk of ice dams but also the risk of your roof collapsing. To prevent this, you can hire a snow removal service, or you can perform DIY cleaning using a roof rake. This way, you can remove the snow before it melts and re-freeze into ice dams.
4. Install ice and water shields
Ice and water shields are waterproof underlayment that acts as a secondary water barrier, especially around vulnerable areas, like your roof’s penetrations, eaves, and valleys. This effectively blocks water infiltration from ice dams.
If you’re planning to repair or replace your roof soon, you can ask your roofing contractor to add an ice and water shield to the project.
5. Seal air leaks in attic spaces
Air leaks cause snow to melt and re-freeze into ice dams. Make sure you caulk or spray-foam any gaps around plumbing vents, light fixtures, or attic hatches. You should also check for cracks or holes on your attic floor where warm air may escape.
By sealing leaks and gaps, you’re keeping warm air where it belongs: right inside your home!
6. Check and maintain gutters
Clogged gutters make ice dams worse. Instead of letting melted snow drain, it lingers on the roof edges until it re-freezes.
So, before winter arrives, make sure that you clean your gutters and check your downspouts for proper water flow. This will reduce the risk of water damage not only on your roof but also your home’s foundation.
7. Use heat cables or roof heating systems
Heat cables are exactly what they’re called – they are cables attached to your roof and warm up to melt ice dams. It creates narrow channels on ice dams, allowing snowmelt to drain off your roof. However, heated cables won’t solve the root cause of ice dams, and they will also increase your energy bills.
Safe ice dam removal methods
If your roof already has existing ice dams, you can remove them through these safe methods:
1. Use a roof rake
Raking ice dams off your roof is the easiest and most affordable method. Roof rakes have long, extendable hands reaching 10 to 20 feet. This allows you to pull snow downward without having to climb up your roof.
Just remember to wear non-slip boots and gloves for your protection. Also, work on small sections and use light pressure so the rake blade won’t damage your shingles or gutters.
Aside from that, avoid using rock salt or harsh chemicals to remove ice dams. They can corrode your roof’s flashing, gutters, and more.
2. Calcium chloride ice melt
Another way to remove ice dams is to use calcium chloride, the same one you use to melt ice off your driveway. But take note that you’re not supposed to throw calcium chloride straight to your roof.
Instead, fill tube socks with calcium chloride granules and install them along the roof’s edge. This way, the calcium chloride will be released slowly and consistently, melting ice dams as they form. Overall, calcium chloride is an effective way to break up ice dams without damaging your roof’s shingles.
3. Professional steam removal
For stubborn ice dams, you can hire a professional snow removal service. They use commercial-grade and low-pressure steamers to melt ice without damaging the roof material. It’s also a wise choice if you’re worried about chipping your roof due to DIY methods.
Although professional steam removal for ice dams is more expensive than other methods, it’s still more affordable than repairing a damaged roof.
Bonus: roof maintenance tips from Boelter Is Better experts
Here at Boelter Is Better, we’ve repaired and maintained hundreds of roofs in Mankato and Southern Minnesota. Here are some of the insider tips we tell our clients, so just like them, you can also avoid repetitive roof repairs:
1. Take photos of your roof periodically
By taking photos of your roof every season, you can track changes over time, making it easier for you to spot potential signs of damage. It will also help professional roofers whenever your roof needs servicing in the future.
On top of that, roof photos will also support your insurance claims in case of storms or accidental damage.
2. Never pressure-wash your roof
While pressure washers are great for removing deep-seated gunk instantly, they are not safe for your roof. High-pressure water can strip the protective granules from your shingles and damage other roofing materials.
If you wish to clean your roof thoroughly, you can hire a professional steam cleaning service or simply perform manual scrubbing using a gentle brush.
3. Don’t block attic vents with items
Maintaining your roof begins inside your home, specifically in your attic. If you’re using your attic for storage, ensure that boxes or other items don’t block the vents. Because if it does, you’re literally obstructing airflow and allowing moisture to build up.
4. Be mindful of your roof traffic
When cleaning or inspecting your roof, avoid walking on it excessively. Make sure you’re stepping on the trusses and rafters for enough support. If possible, use protective mats, so you don’t damage the shingles as you move around.
5. Inspect your roof after a tree work
Did you trim overhanging branches? Or did you just have a tree removed near your house? If so, be sure to perform a roof inspection immediately afterward to check for potential damage from fallen debris.
6. Check for nail pops after high winds
Even if your roof appears intact after a storm, it’s still a good idea to check for nail pops. Roof nails can back out during a storm, leaving shingles loose and vulnerable to damage.
If you spot any nail pops, remove them and replace them with new ones in a different spot. The old nail spot is already loose and wouldn’t hold the new nail for long.
7. Hire professionals for major checks
DIY roof inspections are good roof maintenance habits. However, for major roof checks, it’s best to let a trained eye take a better look. This includes inspections after ice storms, tornadoes, hurricanes, and roof age milestones.
This way, you’ll have a professional and documented assessment of your roof. It’s a wise move, especially if you have to make an insurance claim.
