Why is Proper Roof Ventilation So Important?

What is the purpose of roof ventilation?

CT Ventilation_Black & White

The simple answer is to let the heat out of your attic, but that’s not the whole story.  An effective ventilation system (notice I said system there.  I’ll explain later…) reduces the amount of heat in the summer and moisture in the winter in your attic space.  It helps to make your heating and cooling systems more efficient.  This, in effect, helps increase the life of your roof too.

Now let’s talk about the “system”.  Roof vents, (exhaust), let the air out of your attic, but that air has to be replaced.  You want it to be replaced with cooler air, but where does that air come from?  In addition to exhaust vents, you need intake vents.  The coolest air anywhere around your house is usually under the overhangs, because it is always shaded.  That’s why the best place for intake ventilation is the soffit.  Vented vinyl or aluminum soffit is an easy way to allow cooler air into your attic to replace the hot air exiting through the roof vents.

Generally, you should have at least the same amount of intake as you have exhaust.  A good rule of thumb is to have 1 square foot of ventilation for every 150 square feet of attic space; half should be intake and half exhaust.

Following these guidelines is important to the life of your roof and for your wallet in the long run.  A few indicators that you may not be getting adequate ventilation are if you notice the following:

  • Excessive heat in the attic during the summer months
  • Mold growth
  • Frost on sheathing, rafters or other items in the attic
  • Water dripping from tips of nails (not necessarily due to a roof leak)

If you are experiencing any of these issues, you may have a ventilation issue and should have your roof evaluated by a qualified roofing company.  Also, feel free to contact Jeri Eley in our main office at 757-399-3066 should you have need of our services.

Our People: Joe Wicker, “The Detail Man”

Joe Wicker is definitely a valuable asset to us at Andrews Roofing. I would say that he is “the engineer type.”

He was born in 1963 in Dover, Delaware, but because his dad was in the Air Force he was moved around a little and ended up in Virginia Beach at age 5. He graduated with honors from Kempsville HS and went to work at his grand father’s roofing company that had been started in 1913.

He is an expert in various types of roofing because he has been in the business since then at every level from laborer, to roofer, to supervisor, to estimator and project manager. He is very familiar with roof types including shingles, slate, tile, and commercial flat and low – slope systems like built – up TPO, modified bitumen, and E.P.D.M. White TPO membrane and E.P.D.M. are examples of single – ply roofing membrane systems.

Here at Andrews, he is an estimator and project manager and sometimes sees up to 5 roofs per day. He is definitely a real hustler for us and we are very happy to have him around.

Joe is married to Colletta and has 3 boys. In his spare time he officiates football games with the South Eastern Football Officials Association because of his love of sports. By the way, he can build an electric guitar and of course plays them. He works with wood at home, making types of art such as bowls and pitchers, and even makes ink pens from wood and gives them to our staff at the office.

All this stuff is great, of course, especially the fact that he is a good husband and father. His strongest point as a team member at Andrews Roofing is that he is precise, hard-working and extremely dependable. We can always count on him to do what is right. Joe has been with us since October 2011 and we plan to keep him around for the long haul.

If you have a roofing problem or you need an estimate for a new roof, you can request Joe or one of our other consulting estimators. Just give us a call.

Thanks for reading.

Metal Roof Types

There are many roof coverings to choose from and several of them would work on your home or commercial building. The wide range includes asphalt shingles, metal, shake, slate, tile, and single-ply roof systems like TPO membrane, E.P.D.M., P.V.C. membrane, modified bitumen membrane, etc.

Perhaps the best roof out there is a metal roof. Of course, it must fit the use, but metal roofs look great, perform well, and last a very long time. They also have high wind warranties which make them good on the coast and in wide open spaces.

There are many types of metal roofs. They come in steel, aluminum, copper, stainless steel, tin, etc. They also come in different thicknesses, shapes, and profiles. The paint finishes vary too and have various life expectancies and colors. Some have exposed fasteners and some have hidden fasteners, which are better. The price range is immense also.

Andrews Roofing has a metal roof panel machine. We buy sheets or coils (rolls) of metal material and run it through this machine to manufacture the specific width, length, and shape or profile of the roof panel. Most panels have “standing seams” and make up “standing seam metal roofs.” These are the ones you see all over town.

Many shopping centers have metal mansard roofs on the front of the building to dress it up with a flat roof covering the bulk of the building. Many roofs with shingles have metal accents. We install alot of whole house and commercial jobs too.

To find out the best metal roof for your structure ask an Andrews Roofing rep or another skilled and experienced roofing pro for help.
Most metal roofs will last your lifetime so it will be the last roof you ever have to pay for. They don’t leak either, as long as they are installed correctly.

Thanks for reading.
Good day.

Our People: Jeri Eley, Operations Coordinator

I will tell you what, God has given us at Andrews Roofing some excellent people to get the job done around here. It has taken 17 years to put this team together and I believe we finally have our “All-Star Team.” I am very grateful for Jeri Eley, Operations Coordinator.

In summer 2012, we needed to add a quality person to the operation who would, most of all, carry out our will in taking care of our customers. We put an ad on FB and pretty quickly, Jeremiah Gaines, my senior year Spanish teacher in the 1980’s, responded and said his daughter Jeri might be interested. I knew she was solid because of the character of her dad, who was the best teacher I ever had including all my college professors. We set up an interview and got her in here pretty quickly.

Her strongest characteristic is her integrity. This integrity shines through in the way she carries out her tasks here at Andrews Roofing. She really treats our customers, vendors, and her fellow team members exactly the way that she would want to be treated. And because she has two young children she knows how to stay intently engaged all day, all week long, in the business at hand. She never gives up when it comes to ” making it happen.” I trust her completely to represent Andrews Roofing and myself in many situations on a regular basis because she very much adheres to one of our guiding principles, ” We do what we say.”

Jeri is not a roofer, but understands that we are not just a roofing company. We are in the, “needs satisfaction business.” She patiently does whatever it takes to make sure that especially our valued customers get what they need from their first call in, to when the job is over and they pay their bill. Because of this, we leave a trail of very happy customers who will call on us again for their roofing and guttering needs.

Anyway, enough said, I think you get the picture. Jeri fits the mold at Andrews Roofing and we waited a long time to get her. If you do any business with Andrews Roofing at all, you will at some point deal directly with Jeri Eley.

Oh yeah, I forgot. She grew up in the Churchland area of Portsmouth and got a communications degree from Virginia Tech. While at Tech, she studied abroad in Central Europe and after college she worked in the Chesapeake Public School System helping kids with English as a second language. Then, for five years she was Director of Public Relations at a local marketing firm. She is married to Lance Eley and they have two children, Nora and Claire.

Call or email us and ask for Jeri if you want some first class treatment. The biggest part of her job is coordinating the efforts of our roof estimators and taking care of the customers they serve. One thing she really enjoys and is good at is helping clients pick colors of their shingle and metal roofs. She “owns” our sample room and will be glad to help you best outfit your home or commercial building with the right roof for you.

We look forward to hearing from you soon for all your commercial, industrial, and residential roofing needs.

Nice Looking Low Slope Roof Option: CertainTeed Flintlastic SA Cap

Many homes and commercial buildings have steep slope roof structures where asphalt shingle roofs, metal roofs, slate roofs, shake roofs, or tile roofs will perform well and last a long time. But sometimes they have a slightly lower pitch and need a low slope roof covering like a single – ply membrane. And other times these lower sloped roofs are porches or room additions attached to a steep slope roof.

White TPO membrane roofs are driving the market along with E.P.D.M. and P.V.C. membrane roof systems.

So what if you have a low slope roof that is just sloped enough that it is visible from the ground or a window above and you don’t want a regular membrane roof for aesthetic reasons? A practical, cost effective and aesthetically pleasing option is a granular surfaced modified bitumen membrane roof. I personally like the self adhered type.

By” granular surfaced,” I mean it has the same surface as a shingle. It is covered in granules and comes in different colors. It comes in a approximately 36 inch wide roll and sticks down to the plywood roof sheathing. I recommend one, or even two layers of self adhered base sheet be put down first for best performance and longevity.

This product comes with up to a 20 year warranty and you can closely match your adjacent shingle or other type of roofing with it. I prefer to use CertainTeed Flintlastic SA Cap as a brand.  It comes in 7 colors. This system is not for a flat roof. You must have positive drainage to use it. I would not use it if there is any ponding or puddling of water on a roof after rain.

Please call me if you want to talk about this roof system or any other.

Ice Damming On Roofs Can Cause Leaks

So, here in Hampton Roads we sure have seen some “different ” weather lately. The last snow left eight inches at my house and the very cold temperatures hung around for several days afterwards. I do not recall any storm like it around here in recent memory and I am not looking forward to anymore of it either. In fact, in 17 years of owning Andrews Roofing, I have not seen us this challenged with any weather event as far as scheduling work goes. We are missing many work days this winter because it has been either too cold or too “snowy” or “snow covered” to tear off a roof and put a new one on.

One roof problem this weather is causing more than usual is called “ice damming.” *See the graphic. Ice Dams_013114 This condition can cause some pretty serious leaks.

If your residential or commercial shingle, slate, shake, or tile roof eave overhangs your building in the form of a cornice , soffit, or “boxing” as some call it, you may especially be vulnerable to leaks caused by ice damming. This also happens in roof valleys.

All of your roof that is directly above heated space normally will thaw sooner than parts of the roof that are not. Yes, even though you have insulation in your attic, some heat escapes the living area and into the attic. The snow in this area melts before the snow lower down slope on the overhang eave, which is not above heated space. When the melted snow (water) runs down slope and hits that snow, it can’t escape because of the “ice dam” blocking it. The water backs up and causes leaks because these types of roofs shed water – the material is not water-tight like membrane roofs are. An added complication is when it stays below freezing for several days after snow and even until the next snow. Here we go again with more leaks.

There is a special roof underlayment material that we call ice and water shield. We put it in valleys and around all roof penetrations like chimneys and vents, etc. It provides added protection under the shingle roof in these crucial areas. Up north where snow occurs more often and is deeper, they use this underlayment on the eaves as well, and sometimes architects have us install it on eaves here. It helps to stop leaks caused by ice damming. The thing is that around here, its use on eaves is not very common because ice damming is just not that common of a problem.

If you need a roof soon, you may want to consider this. It will cost a little more, but the ice and water shield underlayment may help to avoid leaks caused by ice damming. The good news is that it may not snow like this again for several years so you may not leak again for several years because of this issue.

Call me with any questions about this or any other roof items. Thanks for reading.
P.S. A rain gutter at the eave can potentially cause ice damming too. Keeping your gutters clean may help.
