Over many years of harsh weather and heat the concrete on your ridge caps/tiles cracks and falls apart due to being originally constructed with concrete, concrete does not flex with the natural movements of your roof, this leaves your roof very vulnerable in a storm due the the caps/tiles no longer being secure as the concrete between the tile and the ridge is all that holds the ridge caps on in high winds etc. In some cases it can even cause leaks just from being cracked.
We repair the sides of the ridge lines with a flexible compound that seals and secures the ridge caps too the roof again, the only difference being it can flex with the natural movements of the roof which prevents it from cracking again...
Another advantage of this product over cement is the wide range of colours available to suit almost any tile colour
The product has a 10 year guarantee against cracking and any other defects.
