Proper Ventilation in a few easy steps

If you are building a new home or if you are re-roofing your home the need for proper ventilation cannot be overstated. Bad ventilation can raise energy costs.  It can cause your roof to warp due to moisture buildup which can (depending on where you live) lead to the formation of ice dams in the winter.  This can lead to roof leaks, gutter damage and increase your future roof and home maintenance costs.

A roof that is well-vented with the amount of intake and exhaust vents will provide numerous benefits to your home and will save you money on energy bills.

Now that I have your attention… All you need are the measurements of your attic and a calculator.  It is really that simple to protect your investment and save money in the future.  Here is how!

1. Find your attic square footage, remembering to include your garage if it is attached.  Let’s say that our space is 33 feet by 37 feet.  All we need to do is multiply the numbers together to find our square footage.

33 x 37 = 1221 square feet.

2. Now that we have our total square footage, simply divide this number by 150.  The Federal Housing Administration (FHA) recommends between 1/150 to a 1/300 ratio depending on the age of your home.  The FHA building codes over the last 20 years are much stricter making them more airtight. This means that newer homes require more ventilation.  For our process, we have a newer home therefore the stricter standard applies.

1221 divided by 150 = 8.14

Therefore, 8.14 is the total square footage of ventilation that will be needed for your home.

3. Convert this to square inches. 8.14 x 144 square inches = 1172.16.  This number is the total square inches of ventilation that will be needed on your home.  Why?  Vents are measured in inches, which makes it easier for us to find our final vent calculation.

4. Lets calculate the intake and exhaust vent percentages.  Most experts recommend a 60/40 split.  This means 60% for intake vents which are usually around the soffits and eaves of the home.  Leaving us 40% for the exhaust vents which are typically found near the roof ridge.  For this we will need two calculations using our square inches number of 1172.

1172 x .60 = 703 square inches for intake vents

1172 x .40 = 469 square inches for exhaust vents

5. With these numbers we can now choose the correct types of vents.  Remember to do your homework.  Make certain that your Contractor if your are building a new home or your Roofing Contractor if your putting a new roof on your home, understands this process and talks to you about it.

Help us welcome Mike to the C.D. Northwest Team!!!

So introducing myself, My name is Mike Gonzalez. I am fairly new to the roofing industry. However my father-in-law was in roofing for 14 years, with 10 of those being during the first 10 years of our my marriage. It always interested me, I learned many things from him and even went out on job sites more often than I can remember.

I have worked in a sales capacity for Many years. From Retail, Media to Mortgage and roofing, the one thing I can say that remains a constant: Relationships are built on: Communication, Trust and Likability. More often times than not I have built a relationship from one or all three of those things versus cost/price. Are we competitive in our pricing here at CD Northwest, Yes! Absolutely! But I believe that people do business with me, and with us because of one of the these previous three reasons. I have great rapport with my clients, they get a sense that they can trust me-because they can, and I stay in consistent communication with them.

I look forward to working with you!

Mike

My Vacation Countdown

I am excited to say that next week I’ll be going on vacation to California. Its been a little over a year that I moved to Portland from California and I think its time to go and visit. I will be visiting family and friends. I’m also looking forward enjoying the nice weather and hopefully I get a chance to go to the beach. Winking smile

Besides all that I it will give me some time to relax because it has be hectic between work, kids, school and at the same time getting ready to move to a new place. That it self could drive someone Crazy. Disappointed smile 

This is a great time of the year to be in California so I will definitely enjoy my time over there. Smile  BUT DON’T WORRY I WILL STILL BE ANSWERING PHONE CALLS AND FORWARDING MESSAGES TO CHRIS AND ALL THE PROJECT MANAGERS!!!!

Driving Complaints??? Seriously!!!

About once a month I get people calling in to complain about one of the driving of one of our employees.  I am just letting you know right here, right up front, I don’t care.  We are a labor and service company.  We spend a lot of time in our cars driving from site to site, we know how to drive.  Our work is stressful, we climb on high places, we manage jobs and have places to be, and often we have to get there in a time sensitive fashion in order for the next phase of the project to be complete or to make sure we can finish a job before nightfall hits.

Guess what?  If one of our reps was honking at you, that most likely means you were not driving that great, and did something to inspire that reaction.  If you are not letting him in when he is merging, don’t call me to sound off when you know you were acting like an ass.  If you are parked in the middle of the road, causing a traffic jam; he might not smile and wave at you.  We are all pretty nice guys here.  We try to have fun, and do everything we can to help our clients out.  If someone working here does indeed piss someone off while driving, I am siding with my employees.  In fact, if you want to call and complain about them, please do, I encourage it and want to hear from you.  Just know that they are not getting reprimanded by me, they are getting a little gold star by their name and a bonus so they can go grab a beer after work.

The California Wine Mixer, er.. Gutters

Hi Derek here, project manager for C.D. Northwest. When roofing your home it is also a good idea to move downspouts to areas that you can collect rainwater. The Portland area gets on average 37” per year rainfall. Why not disconnect your downspouts from the local sewer system and use the runoff from your roof to water your garden. Keep in mind that if you happen to use a moss treatment on your roof be sure that it is one that is safe for your plants. In addition to conserving water and taking a load off the sewer system during times of heavy rainfall you can also qualify for a reduction in your quarterly water bill of about $24.00 for on-site water collection.

Here are a few pics from a project I recently managed where we disconnected the downspout in the rear of the house and moved it to a corner of the gutter nearest the garden. We were able to route the downspout behind a brick structure and then we connected a section of flexible tubing that drains directly to the homeowner’s garden. This particular design is simply used for watering purposes. Rain water collection requires collection barrels and I have provided below where to find the information on that.

I look forward to helping you out with any roof or gutter issues. Have a great rest of the summer !

Certified Shops vs. 1-Truck-Larry: Reiterated

So you’re on the market for a new roof. As anyone who’s ever price shopped a purchase of that magnitude knows, it’s enough of a big ticket item that one feels obligated to shop around. Most people in today’s day and age start that search on the internet, sifting through Justin Bieber fan sites and blog postings regarding the details of the latest Jersey Shore episode to find web pages of roofing companies and private contractors. Maybe you’ve also got friends in the contracting business. After all, everybody knows a guy who knows a guy who has some experience doing random home improvement work.

So you get a few bids from actual roofing shops and a couple of bids from 1-Truck-Larry, everyone’s favorite independent contractor who’ll come throw your roof up with his 2 drinking buddies over the weekend. There’s always one thing in common with this comparison: 1-Truck-Larry’s bid comes in a bit cheaper than any of the certified roofing shops! He’s also willing to offer you a pseudo shake roof from Iko that, while it isn’t quite as pretty as its counterparts from GAF or Certainteed, is still higher profile than a Lady Gaga hat.

So you go with 1-Truck-Larry and save that 500 bucks. Who wouldn’t? The guy seemed to know his stuff, and the wear on his Carhartt jeans coupled with the drippings of random industrial adhesives on his KAT boots suggest that he does this sort of labor pretty frequently. He throws some Iko shakes down on your roof over top of some basic 30 lb felt, and for that first few years, if you’re lucky, your roof looks shinier than T Money’s grill and the Oregon rain doesn’t inadvertently install an indoor swimming pool in your kitchen.

But then you get to year 10, when the basic manufacturer’s warranty on –any roof (which only covers materials) prorates sharply and, on average, drops immediately from covering about half of your reroofing costs to twenty five percent. Generally, all roofs last until this point: Those warranties are written with the understanding that a modern shingle will remain leak-free for 10 years even if you install the roof with a hot glue gun and a Bedazzler.

So at year 11 the leaks start. Why so soon, you ask? Well, as it turns out 1-Truck-Larry isn’t a roof specialist: he does all sorts of contractor work but isn’t truly an expert at any particular facet of home improvement. His cheap, haphazardly installed flashings begin to rust and give way to the elements, and the cheap felt he laid your shakes on begins to disintegrate under the roof, leaving your roof deck rain-soaked and rotten.

So there you are, at year 11, needing a new roof already, and holding onto a warranty that, by now, will cover just under 25 percent of the total cost of getting it redone. Given the rate of inflation, that job now costs roughly 35 percent more than it did the first time around, and that 500 bucks you saved by going with 1-Truck-Larry and his drinking buddies gets flushed many times over on the replacement roof.

Had you gone with a certified roofer, you would not only have gotten higher quality asphalt and accessories to keep your roof alive for easily 2-4 times as long as Larry’s installation, but you could have sprung for a real warranty. The nice thing about being a certified shop is that said certification implies that, not only can they offer you a 50 year, quality warranty, but their roofing crews are expert enough in their job for the shingle manufacturers to stand behind their work. Between the higher initial bid and the added cost of a 50 year warranty, you’ll be looking at potentially several thousand dollars more out of pocket for that initial roof, but in the long run it saves you that extra couple grand several times over. You see, the 50 year warranties that require manufacturer certification aren’t prorated, and they include tear-off and labor costs as opposed to just materials. Instead of three to five 1-Truck-Larry installations eating away at your budget over 50 years, you drop a little extra the first time around and never have to spend another dime on that roof.

At C.D. Northwest, our expert roofing crew carries that certification from several of the largest and most respected shingle manufacturers in the nation, and we’re proud to be able to offer you quality, 50 year warranties for unbeatable prices. Don’t fall into the cycle of reroofing your house every 10-12 years. . . do it right the first time. Choose C.D. Northwest.

Flat Newbies.

Last week Derek and I, being the company’s newest project managers, accompanied our long-time flat roof expert on a gig in Portland’s beautiful West Hills. As you can see from the photos that Derek shot on his iPad, the view from up there was breathtaking.

flat_roof_001    

More importantly, though, the trip gave us the opportunity to walk through and learn the process of putting up a TPO flat roofing product. As a project manager, having a more fine-tuned idea of how to assess the condition of a client’s roof and the labor that will be involved in replacing it is invaluable.

The trip also afforded us the chance to see John “Turf” McInturf, our in house flat roofing expert, in action. The man’s been doing these jobs for well over a decade and it shows in his expertise. On the fly, his measurements and calculations were consistently spot on, his detail work was always accurate and efficient, and his instruction actually made a couple of roofing newbies like me and Derek look like a practiced, coordinated crew. When you put that talent together with the seasoned roofers on our actual labor crew, I can say with all conviction that CD Northwest is the team that you want putting the next flat roof on your home or business!

Meet Derek!

My name is Derek and I am the newest employee here at C.D.Northwest. I am excited to be a part of the sales team and the energy and enthusiasm I am surrounded by is a refreshing and motivating working environment. I have lived in the Portland area all of my life and graduated from Madison high school, received my Associates degree from ITT Technical Institute and I’m a graduate of their Computer Aided Drafting and Design program. I also bring with me to C.D.Northwest my logistical experience from my 11yrs working at United Parcel Service out of the Swan Island Portland hub and zip codes did I mention zip codes? Yes random ones for cities throughout the United States, useful during time with UPS and now not so much. I am a proud single father of a 15yr old daughter named Hannah and although some would say I have my hands full the opposite is true. Having been fortunate to have been there throughout the years leading up to high school it is only now that I feel I am able to focus more of my time into my career. I look forward to meeting all of you. I see a bright future in the roofing industry and have confidence in this career choice.

Sincerely, Derek McCracken
