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.

Holiday Door Decor and Installation

They say don’t judge a book by it’s cover, but people certainly judge a home by it’s exterior. Curb appeal, whether we like to admit it or not, is crucial in presenting your home, especially if you are planning to sell in the near future. Almost all exterior projects enhance curb appeal- 3 major projects are roofing, siding and windows. Those are three obvious features of your home’s exterior that affect the curb appeal of your home, but one component that makes a huge difference in curb appeal is your door. When guests arrive at your home, your front door is the only thing they walk up to and physically touch- making an outdated, damaged door affect your curb appeal in a negative way.
It is the holiday season, so we will give some holiday door decor inspiration and some signs that it may be time for you to consider a front door replacement!
 
Different Door Decor for the Holiday Season
1. A traditional and classic way to decorate your front door during the holidays is to hang a wreath. One of the reasons a wreath remains the most popular holiday door decor is because of it’s versatility. There is the ability to add any sort of accents that complement your style. It can be glitzy, rustic, big or small- you can make it whatever you want!

 

2. Another favorite that is seen every year is garland. Another versatile decoration, it will fit into any style. Whether it is framing the door, wrapped on a railing leading to the entry way, or just draped over the top of the door, it could easily make your door the focal point of your exterior decor.

 

3. Lights! Lights don’t have to be deemed a roof and tree decoration! I’ve seen many people this season hang lights around the door frame. If you have recently got a new door and want to show it off- this is the way to do it in your holiday decorating!

 

When Should You Consider a Door Replacement?
Your Front Door is Damaged
The front door is typically the main entrance to a household. Because of this, it’s susceptible to a lot of damage. Examples of damage are dents, rusting, splitting and squeaky hinges which could put your door’s structural integrity at risk. Between storms, moving impact, rotting from moisture exposure or typical wear and tear your door goes through a lot! All of these examples may eventually lead to security concerns. If your door’s structure isn’t completely secure, it leaves alternative ways to get into your house. For all these reasons, you may want to consider an upgrade!

 

There is Space Under or Around Your Door
Space under or around your door is not ideal for many reasons. A way to tell if you have an unwanted gap is if you see light shining through. A gap can open the door to insects, rodents, water and drafts. Drafts of cold or hot air coming from your door could leave your house temperatures uncomfortable, and it could also mean there is a gap in your door frame. There are temporary solutions to fix a gap, but you will find yourself replacing seals more and more often as time goes on. If you find there are drafts year after year, replacing your door should be a priority.

 

An Increase in Energy Bills
Both damage and space underneath your door will lead to air leaks. A draft coming in through your door makes your HVAC work harder to keep the temperature regulated inside, which in turn leads to higher energy bills. This is especially true in the north east where we experience very hot winters and extremely cold winters. If you are experiencing an increase in energy bills and are unsure why, consider replacing your door!
