When using IKO bitumen roof shingles in combination with the best techniques, the renovations of a worn out shingle roof becomes a mostly simple and inexpensive job. Before starting off any project, first check out whether the existing roof shingle layer could remain in place or has to be removed. Depending on local building codes at least three layers of roof shingles can be applied before stripping off the roof shingles is necessary. 

as their single layer construction allows them to be woven together and to be overlapped more easily. When considering how to shingle a valley with architectural shingles (Cambridge Xpress and Cambridge Xtreme), you must take into account their thickness and reduced flexibility. Laminated shingles are more liable to create bumps in woven valleys. Often they are too thick to be woven at all. Therefor IKO does not recommend installing a woven valley with laminated shingles.
