Flat Roofing Edmonton
We all know that even the best roofing cannot last forever, and there will come a time when repairs have to be done. However, there are some situations in which flat roofing Edmonton is nothing but a waste of time. In those situations, the only viable and cost effective option is replacing the roof. It is an obvious fact that replacing the roof is general costly and laborious undertaking. However, sometimes, repairs may be ineffective, or they may be needed so often, such that their overall, cost outweighs that of replacing the roofing at once.
The following are the circumstances in which repairing a roof is waste of time as the only viable option is replacing it.
When the supporting structure gets weak.
The first point where roofers examine when the roofing has issues is the roofing structure. When the roofing structure has grown weak, replacing the roof only may not effectively solve problem of leaks. When the deck substrate of the roof, in other words, the timber which supports the roof covering is damaged by moisture, termites or the normal tear and wear, then the only solution may be replacing it with another supporting structure.
In fact, when the roof supporting structure is weak, most roofers will not accept to climb or go up it as there is risk of falls. When they find the roof deck substrate is weak, most roofers will recommend an inspection of the entire building. Regardless of the type of roof installed, so long as the roof deck is weak due to internal condensation or leaks within the roofing, this results in hollows or dips in between the joints.
Ridges in flat roofing:
Upon an inspection, if the roofers identify joists beneath the roof deck’s surface, this indicates that in addition to the age, there are other issues in the roofing structure that need to be addressed. Hollows or visible humps in the roof can be caused by two major factors. The first is rotten decking or underneath, or one which has deteriorated due to natural tear and wear. When the check which supports the roof is no not viable, thinking of repairing must the roofing is simply a waste of time and money. In that situation, you should engage a professional flat roofing Edmonton company to replace the entire roofing.
Rotten roof timbers:
When the timber that supports the roofing gets rotten, then the only viable option is removing that timber and any other supporting structure, the roofing, and then putting in place a new structure altogether. The leading causes of damage to the timber which supports the roofing is moisture due to roof leaks over long period time, mold and attack by termites. When the roof supporting structure gets rotten, it increases the risk of falling through in the course of removing it. In that case, do not even think of doing it yourself. Instead, hire professional roofers to do the job.
The bitumen fleet, mostly used as roof deck substrate can also get worn out due to its contraction and expansion for the many years it installed in its place. Imagine the 20 to 30 years of expanding and contracting. Although the roof expands and contracts with cold and heat, bitumen felt may no longer do so, as it will have become brittle and hard, meaning there will be development of humps on top of joints on the underneath joists.
In all the aforesaid situations, it will simply be a waste of your hard earned money, trying to repair the roofing only, without removing the underneath supporting structure. A professional roofing company should be engaged to do the job if you want to get value for money.
