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.

Roof valleys are a frequent source of leaks in older houses. Installation procedures differ depending on the roof type and materials used. We will look here at the basic installation of an open lead lined roof valley.

A roof valley is basically a gutter set between two meeting pitched roofs. Depending on the roof area it serves, the valley is the exit point for a large volume of water so extreme care should be taken with installation. If the roof has been leaking for a while or if there are any signs of rot, you will need to start by replacing the valley boards. Lead sheet is not self supporting and should be placed on treated roofing boards of sufficient strength to hold a large person. (Most roofing contractors are big guys!) Fit boards of sufficient width to accommodate the lead plus 100mm either side. This will give you something to nail the roofing batons to.

The top of the valley boards should be at the same level as the top of the roof rafters. If you lay the boards directly on top of the rafters it may cause the roofing tiles to kick up and restrict water run off. You will need to cut the valley boards to fit in between the rafters. Support the valley boards with studs or noggins. The valley should finish on an even plane at the eaves. It should not kick up higher than the bottom rafters. If it does, you will need to cut the fascia board or adjust the gutter to suit. It is a good idea to fit a tilting fillet each side of the valley. This angled strip of wood runs along the valley length and should be a minimum of 150mm from the centre of the valley. It should sit no higher than the roofing batons with the thinnest end closest to the centre of the valley.

It is common practice to fit a single sheet of roofing underlay the entire length of the valley. The adjacent roofing underlay will rest on top of this sheet. I recommend you use one of the new advanced synthetic underlay materials. The older bitumen based felts are fine for normal roofing situations but are not suitable for valleys. Over time the bitumen will bond the lead to the boards and restrict thermal movement. You should ensure you buy lead of a sufficient grade/code for valley applications. This should be between 1.80mm and 2.24mm thickness. If you are unsure ask your roofing merchant of the correct grade. The lead should be cut into sections no larger than 1.5 meters in length to allow sufficient thermal movement. Bend a welt into the lead 25mm each side. This acts as a last line of defence for water penetration. It also has the added benefit of stiffening the lead, which makes carrying it up the roof a lot easier.

Starting at the bottom of the valley, dress the lead neatly onto the valley boards and over the tilting fillets. The bottom of the lead should allow correct drainage into the gutter. Fix two rows of nails at the very top of the flashing. Use copper or stainless steel nails. Never use galvanised or aluminum nails which will just react with the lead and corrode. I recommend you use the minimum amount of fixing possible to hold the lead in place. If you over fix lead sheeting it will eventually split due to thermal movement. So don't nail the sides. When you have successfully dressed the first sheet you can move up the roof laying subsequent sheets. Overlap each sheet a minimum of 150mm. On lower pitched roof valleys you will need to increase the lap. Where the valley ends at the ridge, you will need to dress the lead so it can sit neatly under the ridge tiles. You are now ready to start fixing the batons and laying the roofing tiles. The key points to remember are to keep the sheet lengths down to 1.5 meters and don't over fix. If you follow the procedure outlined and take care with the dressing you will produce a durable maintenance free valley.

Roofing Contractor Reviews - The 10 Commandments of Hiring a Roofing Company

local roofing companies

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.

Conclusion

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.
