How To Properly Install Ice And Water Shield
Installing an water ice and water shield is non particularly complicated, but accuracy is required. Ice and water shield is a membrane added to the decking of a roof to deter h2o from inbound the structure.
Water ice and h2o shield can exist used on substantially whatsoever roof design, simply it is most normally found on vulnerable areas of a roof. This membrane can be fabricated from any number of materials, but generally speaking, it will always comprise some form of rubber. This makes the water ice and water shield flexible and water-resistant, which are the primary benefits of the product.
Hither'south everything you lot demand to know on how to properly install ice and water shield on your roof.
Why Is an Ice and Water Shield Needed?
To empathise the demand for ice and water shield, it is of import to envision how pelting and snow impact a roof. Some roof designs are steep, while others are flat or most flat. This shape profoundly affects how rain and snowfall leave a roof. To illustrate, consider that on a shallow roof pitch (typically 3/12 or less), rain and snowfall will get out the roof more slowly than on a steeper pitch.
When ice and snow cannot exit the roof rapidly, it accumulates almost the bottom edge where the gutters are located. In effect, this is pooling water, which is the enemy of a shingle-style roof. Ice and water shield is installed in this vulnerable area, so that slow melting, seeping water cannot penetrate to the roof decking.
Fifty-fifty a tiny perforation such equally a nail hole will leak if it is effectively submerged in water. The ice and h2o shield resists this by sealing the pigsty around fasteners automatically. Water ice and water shield is too normally used in valleys because that is where the shape of the roof directs the h2o.
These areas see much more than volume than the rest of the roof, making them vulnerable to h2o infiltration. Water ice and water shield adds another layer of protection beyond the underlayment and covering textile to add years of life to the roof.
What Tools Do I Need to Install Ice and Water Shield?
Interestingly, an ice and water shield typically requires very few tools to install. The tools required will vary by the project of course, but for most jobs, a tape measure, framing square, chalk line, and utility knife volition practise the trick.
Obviously, the need for safe cannot be overstated, as doing any roof repairs is inherently dangerous.
Therefore, installing ice and water shield should only be attempted by those with feel working on ladders and roofs, equally a slight step in the wrong direction tin result in injury.
What Materials Practise I Need to Install Ice and Water Shield?
Ice and water shield comes set to employ correct out of the box. Ice and water shield unremarkably comes in a large scroll approximately 50' to 150' long, and 2' to four' wide. This will vary from manufacturer to manufacturer, so it is a slap-up thought to do some research and determine the correct size for the application. Typically, more is better equally the more product is on the roof, the better it protects.
Is Installing Ice and Water Shield Difficult?
Not especially, but accurateness is very of import to a good-looking job. Professionals will e'er employ a crew of at least two technicians to install ice and water shield, but if the project is large enough, more aid may be needed. This is because the material roll is non only heavy merely quite awkward to handle.
This can crusade a dangerous scenario if a technician loses control of the roll, as information technology not only endangers the installers but anyone on the ground too. Best practices require a combination of help, focus, and patience to practise a safe and effective job.
Can I Install Water ice and Water Shield Past Myself?
Installing ice and water shield solo is not mostly recommended. Notwithstanding, ice and h2o shield can besides be used as spot repair material. For example, if a roof were to take an impact strike from a falling limb, just the area effectually the impairment would require repair.
Many professionals volition not only remove and replace the damaged roofing only will as well patch the surface area starting time using water ice and a water shield. This profoundly adds to the protection of the repair and gives the installer more peace of mind. In these situations, a single installer is ofttimes used, as the entire ringlet will not be needed. Working with smaller sections is easier and will oftentimes be safer.
How To Install Ice and Water Shield (Stride by Step)
- Step 1. Audit the Roof Decking
The first step of installing ice and water shield is to prepare the roof decking. This is washed past visually inspecting the unabridged surface area to be covered and removing any debris.
Oddly, one of the biggest concerns before installing ice and water shield is grit. Covering projects tend to generate dust and debris, which will stick to the self-adhesive backing on the material.
Therefore it is critical that the roof deck exist broom clean before removing the protective bankroll on the material. Also important is to lay out the project visually to determine where, if any seams will exist required. It is not every bit important to stagger joints when using ice and water shield as information technology would exist with other materials, such every bit shingles or siding.
However, it is still a expert practice, every bit it volition foreclose visual undulations that can occur when joints overlap each other.
- Step 2. Mensurate, Mark, and Cut the Materials
The next pace involves computing the amount of material needed. To illustrate, permit'south assume the product we are using is 2' wide and 50' long, which is typical. We want the ice and water shield to completely encompass the roof decking, which is normally OSB or plywood, just information technology tin can be 1" x half-dozen" boards. Next, we measure out out the length we need, so in this example, let's say the house is 48' long. For simplicity, let's as well assume the home is a elementary rancher with a gable roof. Since a 48' longhouse will typically take an overhang of 12" on both ends, we will need a fifty' long department. On the ground, we then utilise the square and using a utility knife or hook blade, easily cut the material.
Pro Tip. Do not remove the protective backing on the cloth until just earlier information technology makes contact with the roof. If the viscous side of the cloth contacts any surface except the roof deck (including itself), it must be discarded and replaced as information technology is nearly impossible to disassemble.
- Step 3. Install Water ice and Water Shield On the Roof's Edge
At this stage, we take the textile on the roof, but nosotros need a reference line to keep the cloth straight. Professionals will exercise this with a chalk line. First, we mensurate from the left border of the roof direct upwardly and mark exactly 24". Nosotros and then do the same on the right side.
Using the chalk line, nosotros then strike a mark all the mode across the roof. Next, we find the middle of the roof, which in this case will be exactly 25' from either side and make another mark two or three feet long directly upward the roof. This is our starting point.
Using help, we gyre out the material above the line and locate the eye of the ringlet, which is over again 25', and brand a mark beyond the water ice and water shield bottom to peak. We now accept intersecting lines we can reference to keep the fabric straight and foursquare.
Next, we line up the vertical marks on the cloth and roof deck and carefully curl the material in towards the lines from either finish. The next step is to flip the material over, and so that the protective backing is facing upwards. Starting from the center, we then remove about 12" of bankroll on either side on the centerline, for a full of 24".
Side by side, the roll is lifted in a higher place the lines on the roof deck and very slowly and deliberately lowered onto the deck, making certain the reference lines are followed. We then carefully press the textile onto the roof, all the while making sure the material follows the left to right line on the decking. This will ensure that no puckers or gaps can class under the material and crusade a hump in the covering.
Nosotros then follow the same process, removing only enough protective backing as needed until the entire section is installed. If needed, an boosted grade can exist added above the first using the same techniques, and vertically overlapping the course by at least 2".
- Step four. Install Ice and Water Shield In the Valleys
Lastly, if the structure has valleys, it is a good idea to install ice and water shield at that place also. The installation procedure will be the same, except in this situation, we will install the textile on one side of the valley at a time to forbid trapping air under the material.
Installing Ice and H2o Shield Is Money Well Spent
Although not all local building codes require ice and water shield, it is a very smart idea. As described here, the fabric really has no downsides and enough of benefits. Ice and water shield is relatively inexpensive to buy and install and works hard to protect one of the most critical parts of a home from expensive repairs.
