Winter Roof Prep

The temperatures are dropping, Christmas lights are popping up, and the days seem to end before they even begin – winter is here. That also means it’s a crucial time of year to prepare your home for the colder weather. Your roof may need some special attention in particular to ensure your home’s safety and comfort over the next few months since it’s the first line of defense against snow, ice, and those dropping temperatures. Here are a few handy tips for getting your roof winter ready.

The first step is always to perform a visual inspection from both the outside and inside of your home. Look for damaged, loose or missing shingles, loose flashing, cracks around pipe collars or areas of moisture or drafts in your attic. Identifying these potential issues first is critical for how to move forward with your winter prep.

During your inspection, you should also check in on your gutters and downspouts. If they’re full from all those falling leaves, it’s time to give them a good cleaning. If gutters are clogged, a heavy rain followed by dropping temperatures can cause your gutters to produce an ice dam, which can cause serious damage to your roof, the gutters themselves and the interior of your home. You may also want to consider installing larger, high capacity gutters and/or gutter guards to prevent future build ups and issues.

Inside your home, inspect your attic carefully, as roofing issues are often easier to spot from this point of view. Damp areas may indicate a leak in the roof or condensation build up from lack of ventilation. Heavy air drafts can also point to punctures or damaged areas. While you’re there, take note of your attic’s insulation – if your home is older, it may be time to replace or add new insulation to keep your home’s temperature consistent, which reduces condensation and your heating and cooling costs.

If you have a wood burning fireplace and chimney, then hopefully you are having it inspected and cleaned at the beginning of the winter season as well. This is a good time to ask your chimney specialist to take note of the flashing around your chimney. Loose or missing flashing around a chimney can cause major structural damage over time, but avoiding this is an easy fix that’s far less expensive than the potential damage it could cause.

Although we don’t get snow very often here in Hampton Roads, when we do, any accumulation can put a strain on your roof. Roof rakes can be used to remove built up snow, which can be especially stubborn on the north side of your roof where the sunlight is less likely to melt it away.

The final winter prep tip isn’t about your roof, but your landscaping. Check the trees and vegetation around your home’s roofline. If there are any branches that are overhanging your roof, brushing up against your gutters or scraping at shingles, they will inevitably cause damage, especially when severe winter weather arrives. Trimming back trees, removing overhanging brush or vines can help prevent problems before they happen.

If you have any concerns about your roof’s winter weather readiness, contact Andrews Roofing today to schedule a roof inspection. One of our experienced roofing specialists can let you know if there are any issues that can be easily handled and repaired before extreme weather hits. Doing so will ensure your comfort and your peace of mind this season.

What You Need to Know About Ice Dams and Roof Damage

With all the recent winter weather Hampton Roads has been experiencing, you may be noticing new issues arising with your house that you don’t normally have to deal with. You’ve probably had to shovel snow from your driveway or walkways, and you may have needed to drip your faucets to avoid pipes freezing. But there’s also something you should be aware of with your roof during inclement winter weather, and it’s called “ice damming.”

What is Ice Damming?

You know the beautiful icicles that form along the edge of your roof after a winter storm? While they look charming, they are actually indicative of an ice dam.

Ice damming happens after a measurable snow event. Snow settles somewhat evenly on your roof, and provided it’s not a massive amount of snow that would cause weight bearing issues, your roof is perfectly capable of handling it. The problem occurs after the storm when heat starts to melt the snow. The heat may come from inside the attic due to insufficient insulation or other air leaks to the attic that allow warm air in, or it may come from the sun. In either case, snow starts to melt and water runs down the roof toward your gutters.  Again, if this happens gradually, and if your gutters are clear, and if the temperature does not drop precipitously, your home’s structure should manage all of this just fine.

Unfortunately those ideal circumstances don’t always happen. What often happens is that the snow starts to melt, and when it reaches the edge of the roofline it begins to freeze. This is because the edge of a roof is likely less warm – not having been heated from living or attic space underneath. Then as the sun goes down, and temperatures drop, the melted snow compiles, freezes and creates a dam at the edge of the roofline. This dam causes moisture to back up, and can also cause shingles to lift, allowing water to get underneath resulting in interior leaks. If this happens, you may notice damp spots on your ceiling or walls, peeling paint or mildew.

What should you do if it happens?

Trying to remove the ice buildup with household tools, shovels, etc. can damage your roof, not to mention be incredibly dangerous for you. Throwing salt on the roof can cause damage to any plants underneath and may not work quickly or effectively enough.

If the ice dam has caused a leak into your attic or scuttle space, you can point a box fan at it to freeze it and stop additional water damage until the snow is able to melt and drain away.

You can also use a roof rake which is a long-handled tool that you can use to rake snow off the roof while you stay safely on the ground. It may not remove existing ice dams, but if you use it right after a snow event, it can prevent ice dams from forming.

How can you prevent future ice dams?

It may surprise you to know that even if a leak occurs from an ice dam, it’s not necessarily because your roof was not installed properly or because of true roof damage. In fact, most ice dams are caused by issues inside the house, not the roof.

The main cause of ice dams is the difference in temperature between the center of the roof and the eaves. Maintaining an even temperature is the first step to avoiding the issue. You can help create an even temperature under your roof by increasing the ventilation in your attic, adding insulation and sealing any air leaks that may be allowing warm air into your attic or scuttle. You should discuss these options with a licensed contractor, as it is not advisable to DIY these important fixes.
