Dimensional Shingle Roof cost estimates may require an onsite inspection. Usually these estimates will be "free". Low to High labor cost range differences are in part due to variations in work load, job location and seasonal wage rates. Ice dam protection at the eaves.

Well, your roof and the home under it need the same kind of protection that an ice and water protector is engineered to provide. This thin, self-adhering membrane is the next component and it gets installed over the drip edge. Ice dam formation is best prevented by having a proper attic vapor barrier, adequate attic insulation and thorough ventilation ; however, an ice protection membrane is a wise roofing system component and is likely required by your local building code in cold climates.

At this time, any valleys on the roof should also be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes work on the principle that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, adding an extra degree of water-shedding protection.

Underlayment for overall secondary roof protection. Both offer you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are many benefits to installing a roof underlayment.

Remember that drip edge we installed at the bottom of the roof? Although this seems to contradict the overlapping principle, installing the drip edge over the underlayment at the rakes creates a clean roof edge and provides the underlayment attachment with increased resistance against wind uplift. Also, any wind-driven rain blowing on the rake edge would cross the top flange of the drip edge and go on top of the underlayment instead of beneath the underlayment where it could potentially cause a problem.

Covering the joints and valleys. If a roof is going to leak, it will most likely occur wherever the shingle layer is penetrated, interrupted or meets a wall.

These are the special areas that require flashing — an added layer of water-shedding material to help keep the water running downslope.

Valleys can either be open or closed — open valleys are not covered with shingles, closed valleys are. If your roof will have open valleys, which IKO recommends, now is when the valleys should be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed during shingle installation.

For longer roof performance, IKO strongly recommends open metal valleys. Complete the application of underlayment and valley flashing before the roofing shingles are applied. The recommended flashing material is a gauge galvanized metal or an equivalent corrosion resistant, non-staining material check with local codes.

The product is tacked in place temporarily along one edge. Carefully peel away the backing, and put it in place, smoothing out any wrinkles. Remove the temporary nails. Install metal flashings where shingles meet walls or chimneys , too. Ice and water protector membranes work well to flash and help protect around skylights, dormers , turbines and other tricky roof areas. Apply flashing materials in concert with the shingle installation procedure , with both the flashing and the shingles arranged to work together to protect around the joint areas.

When applying the new shingles, each shingle course will be covered by a step flashing. Metal Step Flashing Pieces. Note: Other step flashing sizes are also acceptable. To install the flashing piece on the first course, place it over the end of the starter strip. Place it so the tab of the end shingle covers it completely.

Secure the horizontal flange to the roof deck using two nails. Do not fasten the flashing piece to the vertical wall. This will allow the flashing piece to move independently of any differential expansion and contraction that may occur between the roof deck and the wall. Make sure that the tab of the shingle in the second course will cover it completely. Secure the horizontal flange to the roof. The second and succeeding courses will follow with the end shingles flashed as in preceding courses.

They provide a sealant adhesion point for the first course of shingles and provide water-shedding protection at shingle joints as well as at any cut-outs. Professional contractors often recommend and use starter strips along rake edges in order to yield a straight edge from which all the field courses can begin. You must place nails in the proper location and drive them flush with, but not cutting into, the shingle. The hip and ridge caps. Well done!
