Roof Damage Isn't Just What's on the Outside

I recently did work for a homeowner who was shocked to see black, rotten plywood underneath her roof. She never had a leak and wondered how there could be so much damage without any signs, other than an old roof that was deteriorating and needed to be replaced.

I see this problem a lot more often then you might think. In our area of Connecticut, 90 percent of attics don’t have enough insulation and aren’t properly ventilated. I meet people who need a new roof and want me to just replace the shingles to save money. What they don’t realize is how much deterioration exists where they can’t see. Once the plywood is exposed, warping, delamination, and rot from moisture usually come as quite a shock. 

So why does this happen? The issue is actually airflow. Attic ventilation allows your house to “breathe” by taking air in from the outside and letting air out from the inside. Too many homes that I work in aren’t properly ventilated and most have their bathroom and even dryer vents exhausting into the attic instead of outside. 

In order to have proper ventilation, your home needs a system that includes intake ventilation through the soffit or a new product called SmartVent which is installed on top of the roof near the gutter edge. Louver vents were typically used at an exhaust vent in the 1950s and 1960s but now ridge vents are more common. If your house has both louver vents and ridge vents, the louver vents should remain closed, otherwise, the louver will act as an intake vent and will only cool the top third of the attic. 

In the colder months, it’s not uncommon for me to see frost on attic plywood because of inferior insulation. Insulation and ventilation work hand in hand - the ventilation controls the airflow and the insulation controls the temperature. You’re probably familiar with insulation - it’s a cotton-looking fiberglass material that often comes in pink or yellow rolls. It can also be loose-filled into tough to reach areas with a blowing machine. Remodeling professionals put insulation between walls, in attics, and in basements to retain heat in the house in the winter and keep it cooler in the summer. However, without proper ventilation, insulation is just as susceptible to moisture and deterioration as plywood.

My customer never went up into her attic, so she didn’t notice the problem. What she thought was a simple roof replacement ended up being a bigger job simply because, after years of decay, the plywood she had was no longer strong enough to properly support the new roof. Ignoring the problem and laying new shingles over the existing plywood would have voided the new roof’s 30-year warranty.

The lesson for this week? If you’re going to reroof your home, make sure that the plywood is healthy and that your contractor has given you a thorough plan to ensure that your home is properly insulated and ventilated. It might cost a bit more today, but it will regulate the heat and cooling in your home, saving on energy costs and making you much more comfortable for years to come.

Keep Your Home Cooler and Your Outlook Bright

This week I visited a homeowner whose curtains were drawn tight as I arrived outside. I told her I wasn’t sure if she was home and she laughed, explaining that the reason for the dark was to avoid the heat radiating from her old aluminum windows in the afternoon sun. I was at her house to discuss a roof but it soon became clear that her windows were a priority, making her home increasingly uncomfortable before the first heatwave of the summer.

I see this situation a lot in older homes with elderly residents. People don’t want to replace their windows even though they are the most obvious place for warm air to enter the home in the summer and cold air to enter in the winter. New energy-efficient windows can take care of this problem and will also make cleaning and maintaining a whole lot easier too. 

These days, many people are looking to replace their aluminum windows and sliding doors with a more durable option - a product made from vinyl, wood or fiberglass that can withstand the test of time. There are lots of options out there and the one you pick will be based on four very important factors: the climate where you live, the amount of moisture and condensation your home is prone to, the kind of aesthetic you want for your home, and the maintenance required to keep them looking great. Keeping these four deciding features in mind, let’s go through the options.

When it comes to temperature, aluminum conducts heat and cold, which is why it’s a popular choice for cookware. Aluminum windows and doors are notorious for transferring the outside temperature in, which makes them very inefficient in both the winter and the summer. Wood fares better in the extreme seasons, but vinyl and fiberglass windows and doors are made for all-weather and are built specifically to keep the warm air in and the cold air out. Remember that only 10 percent of the window is the frame, so investing in double-pane, energy-efficient glass is your best option, no matter what frame you go with.

With our humid summers and damp winters, moisture is a major factor in deciding whether to upgrade your old windows and doors. Because aluminum transfers heat, it can attract condensation and moisture, which can lead to leaks, mold buildup, and rot inside your wall. The mold build-up I see around old windows would scare the life out of you, especially when you remember that you’re breathing those spores in every day. If you have signs of mildew or corrosion from your aluminum frames, it’s time to get them replaced.

Then there is the “look and feel” factor. Many people started replacing their aluminum windows and doors with vinyl so they could achieve a more contemporary look with the various finishes and designs that vinyl offers. Of course, aluminum products can be painted or powder coated to match the style of your home, but there will be maintenance to keep them looking great.

That brings us to upkeep. Be aware that any painted product will begin to chip and peel over time. The look of wood is elegant and timeless but it requires regular painting or staining, just like aluminum. Vinyl and fiberglass are very easy to care for and they don’t peel, fade or need to be repainted. These products are not prone to scratches, dings or dents and can give you a longer, hassle-free lifespan if you take care of them properly.

With summer in full swing, now is a good time to think about replacing old windows and doors for products with maximum energy efficiency and minimal maintenance. If your home still has aluminum and you’re experiencing some of the problems I’ve mentioned, it might be time for an update.

Replacement Windows for Less Maintenance and Energy Efficiency

If you swore that this past winter would be the last time you’d put up with drafty, old aluminum windows, this week’s column is for you. Around this time of year, I get calls from lots of people looking for advice and information on replacing their windows. Not only do old windows let lots of warm air out and cold air in, but they are also difficult to clean and maintain.
