You’re a homeowner and determined your home’s roof needs fixing or needs to be improved with a replacement roof. You’re all set to get moving. What’s the optimal way to get a high quality roofer who will accomplish a good job? What could you look for in a roof contractor or contractor to obtain this work? Simla
When homeowners choose to repair a roof or replace that roof with asphalt during the cold winter months, they’re often plagued by worries that their family will freeze before the job is completed. In the same vein, those starting a roofing job in the sweltering summer months worry that they’ll be facing heat stroke. These concerns are perfectly normal and common among many homeowners looking for roofing fixes or roof replacement contractors.
Imagine, you're standing on the sidewalk, looking at an average house. You see the siding, the windows, the front door, and way up above, you see the roof. Does the roof have asphalt shingles? Wood shakes perhaps? Maybe it's made of metal or rubber tiles? What you see is where the focus goes, but it's what you don't see that really matters. There's more to roofing than meets the eye. So let's talk about what goes on, under the shingles.
The Roof Deck
We learn to crawl before we walk, so when talking about roofing let's start with square one, the surface area of your roof which is made of wood. Your wood roof deck is comparable to an automobiles metal body. It is installed on top of the basic house frame to give a surface area on which to install Shingles. Without a roof deck installed on your house, there would be nowhere to install your Shingles. And of course without the shingles, your roof deck would rot away due to exposure to the sun, rain, snow and ice and etc...not a comfortable home at all!
On Newer Houses, sheets of plywood or OSB boards are fastened on top of wooden trusses in your attic to form the roof deck. Plywood or OSB boards are installed in a staggered formation with small spaces between them to allow wood to expand and contract as the wood heats in the summer and cools in the winter. Older homes often have lengths of 2" x 6" installed instead of plywood or OSB board. When the time comes for you to replace your Roof System, remember to have your Calgary Roofing Contractor replace any and all damaged wood.
Remember, if your roof deck is rotting or damaged in any way, people walking on your roof could potentially crack or break through the wood, causing further damage to the roof system, such as to the shingles...and to the person who walked on it! However, most roof decks can withstand a little bit of exposure to water or ice before it needs to be replaced.
Metal: Drip Edge and Rake Edge
Drip edge and Rake edge is the first part of the Roof System to be installed. It is a long and narrow piece of metal which is installed along each end of your Roof Deck, ie: along the eaves trough and along the gable ends.
Some area local building codes require the installation of Drip Edge and Rake Edge and other building codes do not. Check with your local city building offices to find out. In Alberta for example, the Building Code does not require the installation of Drip edge or Rake edge. Therefore many new homes and/or low budget roof systems do not have drip edge installed in order to allow for more affordable roof prices. We recommend however that Drip edge and Rake edge be installed on every Roof System, no exceptions.
Choosing an appropriate Leak Barrier and installing it properly is an important step in every Roof System. Speak with your Roofing Contractor to learn more about leak barriers, how to choose the right one and how to choose a Professional Roofing Contractor to install it.
Roof Deck Protection
Roof Deck Protection is very similar to a Leak Barrier. The difference is that Roof Deck Protection is installed on the entire Roof Deck area instead of only on "special areas" as we mention in the Leak Barrier section.
Typically, Roof Deck Protection is a step lower in quality than a Leak Barrier. As with Leak Barriers however, there are many different types of Roof Deck Protection available to choose from ranging from basic felt/tar paper to advanced plastic woven sheets of rip and wrinkle proof material. Choosing a reliable Roof Deck Protection is an important part of a quality Roof System.
A word of caution; most roofing companies use felt paper as Roof Deck Protection. Although using felt paper is a standard and acceptable practice, some issues can arise if the felt paper becomes wet during or after the installation. Ever notice how paper tends to curl when it dries after it was wet? In a similar way, felt paper can curl if water or excess moisture touches it. For this reason, and because the cost is quite small, we recommend installing a higher quality Roof Deck Protection such as a GAF/ELK Deck Armour. For a relatively small additional cost, you'll be rewarded with a much more reliable Roof Deck Protection.
Ask your local trusted Roofing Contractor about which under-layer would be best for your Roof System any why.
So there it is, life beneath the shingles. See how much goes on behind the scenes? Professional roofing contractors know this stuff inside and out and can help immensely in ensuring a roof system is reliable for many years. Product suppliers such as GAF/Elk and IKO can help answer specific questions about products as well.
All the best with your roofing project, and remember, be proactive, make educated decisions.
Roofing - A Guide To Installing Corrugated Iron Roofing
Corrugated Iron Roofing is durable, lightweight and easy to install. If a few extra precautions are taken with handling and fixing, the finished product will greatly be improved.
Over half of the mistakes made while constructing a corrugated iron roof can be traced back to incorrect storage or handling. The iron has to be handled and stored correctly because the surface is very easily damaged.
Leave the metal roofing at the manufacturers until you are ready to start installing it. Aim for delivery the day before roofing starts. If the roofing iron arrives before you are able to fix it, you must ensure it is kept bone dry. It is a common mistake to assume that because they are roofing sheets, they can withstand moisture. If the roofing sheets are stacked together and they get wet, they will stain. White rust forms on the coating and it is very difficult to remove. If your roof sheets do get wet, separate each individual sheet. Use bearers to allow airflow around the metal. This will prevent the corrosion.
Gently does it
As for handling, care needs to be taken in order not to damage the paintwork. Sliding sheets across one another will damage them. When separating the roofing sheets, you should lift them cleanly upwards without scratching the one underneath.
Laying the roofing
Before you start laying the roofing sheets check that the roof is square. If the roof is not square you can still achieve a good finish if you even out the difference, between the two barges. The difference will then be less noticeable as it will be covered by the barge flashing. Run a string line along the eaves, 50mm into the gutter and it will provide you with a straight edge for the roofing sheets.
On completion it's important to clear the roof of any loose swarf. Tiny particles of iron left on the roof will rust and ruin the surface. A soft brush will do the job or ideally a leaf blower can be used.
A well installed corrugated iron roof will give years of maintenance free service. If you take a little extra care with the preparation and fixing, you will achieve a superior finish.
