Ice Dams: Causes, Dangers and Preventions

With cold temperatures and possible snowfall in the area this upcoming week, we can all agree that we are officially in the winter season. Preparing your home for the winter is essential in preventing any major damage. Preparations such as checking your windows and doors for leaks and gaps, cleaning out or replacing old gutters, checking for damage on your roof and taking proper precautions to prevent an ice dam development are all important. Ice dams could lead to substantial damage to your roof, gutters and the overall integrity of your home. We share multiple tasks you could complete to avoid an ice dam from happening

What is an ice dam?

An accumulation of frozen water in the gutter system and at the roof edge that prevents subsequent drainage of melting snow from leaving the roof/gutter system.

What causes an ice dam?

Ice dams are caused due to lack of ventilation in your attic. When the heat is on inside your house and rises it leaks the hot air up through the roof. This in turn creates warm areas on the roof, which causes the snow in that area to thaw. Once the snow is fully melting, it glides down the roof’s slope until it reaches the frozen overhang on the edge where it refreezes and is consistently built up to a dam structure.

What is the danger of an ice dam?

This build up of snow and ice can be very dangerous to the integrity of your home exterior. It could tear off your gutters, loosen shingles, and eventually could lead force water to back up underneath the shingles which may cause a leak through your ceiling and into your home. It’s possible that ice dams could also cause decaying, corrosion and mold to form in your attic and on the wall surfaces.

 

As you can see, ice dams could be very dangerous to the structure of your home and could eventually become pretty costly to repair. So how do you prevent this from happening?

Ice Dam PreventionGutter Maintenance Clogged or older gutters do not cause ice dams to happen, but they tend to make the issue much worse. Cleaning out or replacing older gutters could easily save you the headache of an ice dam because it will prevent the initial foundation of ice to form along the edge of your roof.

Proper Insulation The best way to stop ice dams from forming in the first place is to make sure your attic is insulated well. This keeps the heat inside where it belongs.

Ventilation A ridge vent paired with continuous soffit vents circulates cold air under the entire roof. Both ridge and soffit vents should have the same size openings and provide at least 1 square foot of opening for every 300 square feet of attic floor. Place baffles at the eaves to maintain a clear path for the airflow from the soffit vents.

Cap the Hatch An unsealed attic hatch or whole-house fan is a massive opening for heat to escape. Cover them with weatherstripped caps made from foil-faced foam board held together with aluminum tape.

Exhaust Make sure that the ducts connected to the kitchen, bathroom, and dryer vents all lead outdoors through either the roof or walls, but never through the soffit.Sealed Can Lights If you have recessed lights, replace them with sealed can lights to minimize referred heat to the roof.Seal and Insulate Ducts Spread fiber-reinforced mastic on the joints of HVAC ducts and exhaust ducts. Cover them entirely with R-5 or R-6 foil-faced fiberglass.

Spring is Near. Is Your Roof Ready?

The sweet smell of spring means warm weather is on the horizon and it’s time to plan accordingly. Along with planning summer fun, spring is a common time for homeowners to hit the reset button and get their property in tip-top shape. Standard projects include cleaning, landscaping, decorating and organizing storage spaces. We at MLM believe roof maintenance is an equally important and essential component of one’s springtime housekeeping regiment. Winter can be a roof’s greatest test, making spring the ideal time to run through a checklist of maintenance tips. These four considerations will help your home and family transition at the beginning of every spring.

1. Clean and secure your gutters.

Chances are you spent little time monitoring the exterior of your home during the winter. At the minimum, leaves and twigs may have accumulated in your gutters and created a clog. Even worse, strong winds and winter precipitation may have stripped the gutters from your home. Unfastened gutters are not only a safety hazard; they are less effective in their role of draining water away from the foundation of your home.

Clearing your gutters early in the spring will prepare them for the heavy seasons of rainfall ahead. Confident DIY-ers can complete this task with a ladder (and partner), garden hose and some elbow grease. However, if there is major clogging or loosening between your gutters and house, we recommend bringing in a trusted, local contractor who will get the job done safely.

2. Trim tree limbs and branches that touch your roof.

Trees that touch your roof can shorten its lifespan and increase the risk of a sudden puncture. As branches sway in the wind, they can graze your shingles and scrape off protective granules. Therefore, it is important to trim branches before they grow larger and apply more pressure to your roof. As a bonus, trimming branches will expose your roof to more sunlight and reduce moisture levels. This will prevent the growth of moss, which is too heavy for your roof to host safely.

3. Inspect the ceiling of your attic for signs of deterioration. By noticing warning signs early, you’ll be able to address any issue before your roof falls victim to serious, costly damage. The easiest way to do so is by inspecting your attic ceiling for signs of moisture. Cracks, discoloration or sagging are signs that water has infiltrated your shingles and begun decaying the structure of your home. Especially common if your roof experienced snowfall over the winter, these situations are much easier – and cheaper – to address before water seeps into your attic.

If you notice a leak, set up a professional consultation as you may need a more involved repair or a full roof replacement.

 

4. Schedule a roof inspection with a trusted, local contractor. A healthy attic ceiling does not necessarily mean your roof made it through the winter unscathed. Each spring, schedule a roof inspection with a contractor, backed by a national manufacturer like Owens Corning, who can detect damage unbeknown to the untrained eye. Annual roof inspections play a critical role in the upkeep of your home, not dissimilar to cleaning your chimney or replacing your air filters. Addressing minor roof damage early will keep your home safe and save you from costly repairs down the road.

Spring is ready, are your gutters? Ask yourself these 3 questions!

The severe winter weather we experienced just a month ago could have intensely affected your gutter system. Leaves, broken branches and other debris will block your gutters from doing their main job- keeping rain out of your house. Gutters are so easy to overlook, making them the most neglected and costly repair a homeowner can face.
Why wait until a major rain storm? Here are 3 questions you can ask yourself to make sure your gutters are ready to withstand spring showers and to avoid and prevent larger (and costly) issues!
1. Is there any visible damage on your gutters?
To answer this question, check out your gutters on a sunny and dry day. Are there holes in your gutters that are causing leaks? Are there gaps from one gutter to the other? Are your gutters starting to separate away from your home? Are there rust spots? If you answered yes to any of these you may want to call a professional to inspect them. These are clear warning signs your gutters are starting to become ineffective. We encourage a free inspection to see if your gutters simply need a repair or if you need a new system.
2. Are your gutters clear of debris, leaves and other undesirable growth?
Spring is definitely the time to make sure your gutters are clear of any unwanted debris! Gutter maintenance only needs to be done about twice a year for it to be effective so we suggest you complete these bi-yearly cleanings or hire a professional to do this service for you. It will definitely save you money down the road!
3. Are there dirt channels or pooling water underneath?
If there is an overflow of water underneath your gutters, this is a tell tale sign you will need to replace your gutter system. Gutters that are not able to properly do their job of keeping water from your home have no purpose anymore! Call us to come out and inspect your home. We will give you a free estimate, and can ensure you an easy and efficient replacement!

Gutter Guards: What are they? Do you need them?

Clogged gutters can be very harmful to your home’s exterior. Gutters that are clogged or not working properly can lead to damage to your roof, soffits and fascia, and mold and erosion around the foundation. We understand that cleaning debris out of your gutters isn’t a desirable way to spend a day off, which is why we offer gutter guards. The installation of gutter guards completely eliminates most of the maintenance required for long lasting gutters.
What are gutter guards?
A gutter guard is a piece of hardware you install to cover your gutters. Gutter guards allow water to enter and keep debris out.

All of these natural things that happen out of your control severely affect the integrity of your home. Gutter guards allow these worries to disappear because of the protection they guarantee.
The effectiveness of your gutters are not typically on the forefront of our minds. However, a failing gutter system can lead to some unfortunate damage. With the installation of gutter guards, they can stay on the back of your mind and you can be confident everything is working properly.

How To: Clean Your Gutters

Gutters are an integral part of your exterior home because they protect it from hazardous water damage- your roofing, siding, windows, landscaping, and foundation would all be ruined without proper rain gutter installation! If you’ve read our latest blogs, we continuously state the importance of cleaning out your gutters twice a year. Neglecting this chore unfortunately can lead to extreme damage, as they may be clogged, overflowing, filled with debris etc. So- how do you properly clean your gutters? If you’ve never done it before, it may be intimidating. Here is a step by step guide!
Step 1: The Ladder
The first thing you need to do is properly secure your ladder so you can be eye level with the gutters. We recommend securing the ladder to the house to make sure nothing goes awry. Take proper safety precautions while doing this step- and if you’re unable to get up on the ladder, we recommend hiring a gutter cleaning service.
Step 2: Gloves
After you have secured your ladder and eye level to the gutters, put your gloves on. From the ground you have no idea what you might find in your gutters, branches, debris, even kids toys, so having gloves on will allow you to pick up any unwanted items out of the gutters.
Step 3: The Hose
Once you’ve gotten rid of obvious debris, you’ll want to bring your hose up and flush out your gutters. It’s important that the pressure of your water isn’t to intense and that you’re angling your hose correctly. A harsh water stream straight on your gutters could cause damage. Flushing out your gutters with a hose will get rid of any hard to reach debris. *Tip: do not use a shop vac or leaf blower. These tools will cause more mess than anything!
Step 4: Inspection
Now that your gutters are nice and cleaned out, it’ll be easier to detect obvious damage. If you see any leaks, rust, peeling paint, sagging gutters, or even cracks or broken downspouts, it’s time to call in the pros. Your gutters will need repair or even replacement.
Step 5: Damage?
After your own personal inspection, if you find any areas of concern- call MLM! We will come do a free inspection and let you know if these concerns require a replacement. 1-844-MLM-ROOF
Every gallon of rainwater weight roughly eight pounds. If your gutters are clogged and overflowing, they could potentially be holding thousands of pounds of debris and water. This is extremely dangerous as they can cause water damage, completely pull away from your roof, or even result in a roof collapse. Follow this gutter cleaning guide at least twice a year to prevent these dangerous situations.

Summer Roof Maintenence

This weekend is Memorial Day and unofficially marks the start of Summer 2021! Summer is a season full of outdoor activities, days at the beach and barbecues. But it is also the hottest season, and the temperatures will be rising. Depending on the person, you may love the hot temperatures but your roof does not! In our previous blog we mention how high temperatures can negatively affect your roof as time passes. So how do we prevent any damage? Follow these summer roof maintenance tips and you will have a healthy roof!
Remove debris
A very important place to start is removing any excess debris that is lingering on your roof or in your gutters. This includes twigs, branches, leaves and any other undesirable debris. While doing this, safety should be your number one priority- if you are not able to climb up to the roof, we recommending hiring someone to do this step. This also should be done by hand with gloves, or any other tool such as a leaf blower. Avoid using a power washer. A power washer, though seems like a logical idea, can cause unwanted damage due to the focused pressure.
Check for mold, moss & algae
The summer brings heat and also humidity from all the rain, which increases the chance of algae to build up on your home. If left untreated, algae can eventually eat away at your roof leading to roof decay. Moss left on roofs can cause shingles to curl and crack. Heavy moss can block water, create buildup under the shingles, and eventually damage the roof deck. If you see moss or algae on your roof, remove it ASAP to prevent these problems. Mold damage can happen fast, so it’s essential to check your roof often.
Trim trees
An important tip is to trim the trees that overhang on your roof. Summer is known for it’s unpredictable storms, and it wouldn’t take much for a branch or limb to break off of the tree causing damage to your roof. Trimming back your trees so they are about 8 ft. away from your roof will prevent damage and a possible roof replacement. Trees that are over your roof could also cause damage to the gutter, if leaves and twigs are falling off and weighing your gutter system down.
Check your attic

Attic insulation is critical in the summer because it’s what’s keeping all of the heat it’s absorbing out of your living space. It’s also important to check for any signs of moisture or mold while you’re up there, as this can point to water leakage.Here are some signs of roof mold damage you can see from your attic:

  1. If you discover watermarks along the ceiling or walls of your attic, your roof may have a hole.
  2. If your attic smells musty and you spot mildew across your ceiling, you have a roof leak.
  3. Discolored rafters mean the wood has absorbed the water from a leak above on your roof.

Schedule a roof inspection

At MLM, we provide free roof inspections. It costs you zero money out of pocket for us to come and inspect your roof for you. Inspecting these things yourself can turn into something more complicated, and unless you have roofing experience you might not be 100% sure what you need to look for. MLM employees are highly trained and will take all of that stress off your hands. Remember- preventative maintenance is better than serious repairs and replacements (and cheaper!). Call us at 844-MLM-ROOF to schedule your appointment.
