Coatings For a Steel Roof
A metal roof can be a challenging roof surface to seal from the elements. One of the major factors is the constant expanding and contracting of the surface itself. A metal roof can expand and contract as much as 2 inches every 100 foot which can be devastating to fasteners and seams, which 90% of all roof leaks take place at these points.
If you are experiencing problems with a metal surface then the two options are to either replace the roof which can be extremely expensive and time consuming or restore it with an elastomeric roof coating, which can be very cost effective in comparison with replacing the roof.To know more about coating services visit Zirconia Coating India and Surface coating India
A high quality elastomeric roof can add many years of lifestyle to your existing roof, they come in several different forms but the high quality ones are generally more expensive but should be the only selection. Lower cost coatings don’t stretch as well and seldom have the proper UV protection built into them.
Another key feature in Elastomeric coatings are the energy savings you will benefit from them. Immediately after coating the steel roof surface its temperatures can drop as much as 40 degrees or more in a very short period of time. This reduction in heat exchange from your roof will make your building much cooler and will save your money in your energy bills.
The coating however does not simply just work alone, there are steps necessary to ensure that your framework is properly sealed from the elements. The first issue that must be done is to ensure a clean surface, this should be performed with a high power pressure washer to remove hard to get roof scum. Next you need to go around the roof and spray all rusty areas with an inhibitor to stop further deterioration of the steel.Get more info about Coating systems here.
You should then go around and reinforce any where there is a roof penetration with elastomeric roof cement, by penetrations I mean pipes, air ducts, enthusiast units and any other areas where there is something entering through the surface. You them also need to move reinforce or replace prexisting roof flashings that may be running around the roof. After the surface provides dried the next step is to seal fasteners individually with a rivet guard type material and all missing fasteners should be replaced as properly. After this step you must individually seal every seam with a seam guard, this is usually a roll out tape, a really heavy elastomeric cement or a combination of both of pending on the product you are using.
Now finally you can coat your roof with the final roof coating to finish the job. You will need a roof coatings sprayer which you can pick out up from a paint supplier just be sure that you transformation the sprayer head with the proper size for your roof coating. You may need a primer layer depending on which product you are using and you should put down two coats of surface finish roof coating material as well.
Be sure that the roof surface is dry and that now rain is forecast for the day you decide to finish the roof. Elastomeric coating will not stick to a wet roof surface so be sure that it is good and dry. Temperature is also a key point, it should be no less then 55 degrees to put down the roof coatings to ensure that it cures properly.
That is virtually how you would go about sealing your metal roof. You should hire a qualified roof coatings contractor to do the work but if you should save money you can complete the project yourself.
