Most people are not aware of what is going on under their shingles and honestly some of us couldn’t even choose what we have. Most roofs haven’t had a proper system installed causing their roofs to deteriorate prematurely and so many other related issues, so it’s time for you to get well inform and to make that big investment worth it.
We will share with you….
Having a layer of underlayment provides extra protection between your shingles and your roof deck (wood), which is why choosing the right one is very important and believe us, it makes a big difference.
Typically in most roofs you will find a 15 lb. or 30 lb. black felt, an asphalt-saturated sheet, this product is basically a thick paper felt, that usually absorb moisture that leads to wrinkling, becomes brittle and could leach oils.
This felt you can easily torn or wrinkle with your own hands with out taken his original state completely back, if something like that happens during your installation you will end up with a bumpy roof, since the waves in the felt will transfer to your shingles ending up in a non good looking roof.
A high quality roofing system uses a synthetic felt(called FeltBuster for GAF product / ProArmor for Owens Corning product)
Synthetic products are manufactured from polypropylene and polyethylene. Synthetic underlayments offer a variety of advantages over the roofing felt, such as tear resistance, UV resistance, and they don’t wrinkle when exposed to moisture like roofing felt does.
Other advantages of working with a synthetic felt are:
An other important component that your roof should have is a leak barrier.
In regions where snow and ice are pretty common during the winter months, having an ice and water shield in addition to roofing felt makes a watertight and energy efficient covering for the roof.
There is a mineral-surfaced leak barrier and a film surfaced leak barrier.
The mineral-surfaced is a fiberglass mat-reinforced membrane with mineral fines on the top surface and the film surface leak barrier is a fiberglass mat-reinforced but this one has a membrane with a polymeric film on the top.
Both membranes help prevent leaks caused by roof settling, wind-driven rain and ice dams on the most vulnerable areas of your roof which are your eaves, rakes, your valleys, around the chimney, sky windows, pluming vents among others.
Although both products have really good qualities protecting your roof like:
The film surface leak barrier also has:
Once you have your deck and vulnerable areas protected you must think that is time to shingle, but we still have some important steps to cover.
Drip edge: you must have them installed on your roof, it should go on your eves and rakes, this will prevent water to roll back to your deck, which will absorb the water and rod.
Starter Strip: back in time what roofers used to do at the edge of roofs was to turn a 3-tap shingle backwards; the problem is, this shingle wasn’t designed for this purpose and a lot of roofs were installed with them.
Starter Strip shingle is a long, usually made of asphaltic material strip that goes at the edge of the roof, it comes with a line of adhesivewhich bonds with the shingle placed above and seal them down protecting them from the elements, a 3-tap shingle doesn’t have this adhesive so with out a proper starter strip, a gust of wind could blow them off or wind blow rain could get beneath those shingles that aren’t sealed down.
Some roofers claim you don’t need a start strip shingle, but actually installing them provides you that crucial extra layer of protection.
Now, shingles, there is a huge variety out there, different shapes, materials, colors, thickness, quality, you name it, so which one to choose?
You will choose that beautiful color and shingle design that will make your house to stand out in your neighborhood and of course the one that best works for your specific needs, however there are a 2 other important things to look for in a shingle.
A standard roof installation requires 4 nails per shingle, however, in order to provide a high wind resistance roof an enhanced nailing pattern of 6 nails are used instead to allow enough hold against the elements and prevent shingles to blow off the roof.
A really good shingle is one that allows an efficient installation as well, many brands doesn’t show the workers where a nail should be in order to obtain the maximum benefic out of the product, but “they should know where, right?” lets think about it for a moment, 6 nails per shingle in a whole roof, that could mean thousands of nails so that means there could be a possibility that they don’t hit the target a 100% of the times and lets not take this lightly, if a shingle gets nail lower or above an specific area, that could jeopardize its integrity causing weak spots that could lead into leaking or even the shingle to blow off the roof.
Owens Corning a shingle manufacturer company has actually incorporated in their shingles a woven-fabric nailing stripthat enhance its performance by helping deliver a 130-MPH wind warranty and provides an easy to see, strong and durable nailing zone, so workers don’t have to guess.
Another important feature to look for in a shingle is thermal sealant on the back, this will help the shingles that are on top of each other to firmly bond together, covering the nails as well, protecting them from corrosion.
So, we just picket out the perfect shingle, what is the next step?
A good roof vents means a healthy home and is crucial in roof design since it will provide a proper attic ventilation which helps prevent early aging to your roofing materials, moderates the attic temperature and prevents moisture to grow in your attic.
There are different types of vents but which one works best?
Again, most roofers use a 3-tap shingle to cover the ridge vent and once again this shingles weren’t designed for this purpose, which is why GAF and Owens Corning have a specialized Hip & Ridge Cap Shingle, this product is much thicker that a regular shingle and it was made to bend according to the pitch of your roof with out cracking as a 3-tap shingle would do, the cap shingle will also have a thermal sealant so they will bond together and this will insure you that your nails won’t be exposed and your cap shingle won’t be tear off your roof.
Last but not least, Pipe jacks. When a homeowner contacts a roofing company for leak problems 7 out of 10 times the leak is happening around the pipe boot. Whether is it that a new roof it’s going to be installed or just replacing a pipe jack you need to know that what goes on your roof it’s a high quality product.
Lets talk about standard pipe jacks shall we?
Now, lets talk about an Ultimate Pipe Flashing the name says it all but lets elaborate:
· This pipe jacks has a Kynar PVDF coated 24 gauge galvanized sheet metal plate. PVDF is a a specialty plastic used in applications requiring the highest purity, and because of its purity, it also offer resistance to abrasion, impact resistance, thermal stability, making it the ideal choice for the development of highly durable and substantially lighter materials.
All this features will give you a lifetime tool, so which one would you rather have on your roof?
So, now that you know what should be on your roof, don’t hesitate to demand the best products out there and we at Daniel Hood Roofing Systems will provide you the highest quality in service you can experience on any home project.
