Should I get a roof coating?
Houston based, Texas Roof Coatings can use professional grade sprayers to repair or restore your commercial roof. For smaller projects or jobs that require more detail we'll do all the work by hand to ensure quality craftsmanship. If your roof is getting older and you're worried about it to start leaking give us a call and we will come out to provide a 100% free estimate.
Too many roofs get pre-maturely torn off and replaced, while some maintenance and restoration work could have been done to save the existing roof instead. Roof coatings can prevent a costly tear off in many situations.
The last 15-20 years has shown great changes of coatings as so much more than just a maintenance item to a full-blown roof in and of itself and have been referred to as "liquid applied roofs" where roofers are considered to be "manufacturing" a roof membrane on the roof site by applying these project to a roof surface , and in some cased, using the coating directly over a fiberboard or poly-ISO substrate, to create a new roof.
While coatings have tens or probably well over 100 brands, there are 5 types that exist:
Types of roofs that we coat:
• Metal roofs
• Mod Bit
A great benefit to using roof coatings is that while a building that has two layers roofing installed needs to be completely torn off, in order to install a new roof (according to building codes) , a coating system can be applied on top of the roof layers and not be considered a third layer of roofing. By Texas building codes. Coatings are considered to be maintenance project and do not require a permit.
Coatings can be used to repair areas of a roof or over an entire roofing surface. Also, can be used just around penetrations, and seams and can embed a fiber-mesh or fabric into the coating, and coated again for a very effective and durable sealant.
Coating system start with removing debris or dirt from a roof. Metal roofs with rust can be pressure washed or rust can be applied with a primer or phosphoric acid. Also RRC condition helps with rust. Seams can be sealed with a thick grade coating and fabric, then the entire roof can be coated with one, two or three layers, each one adding additional life span to the roof.
Repairs to an existing roof can be done prior to coating. Metal panels can be replaced if rusted through, screws are tightened or replaced and "rig stiffeners" used on metal roof where the ribs of the panel have deteriorated and screw head are coated first with a thick grade, for added protection . Metal roofs horizontal seams can be "3-plies" or "3 courses" first due to their being prone to leaks with age. Vertical seams are not as problematic. Therefore are not fabricated. But a "bead" of coating can be used if need, prior to coating the entire roof.
Roof coatings can be rolled or sprayed on cover. Coating can be delivered in 5-gallon buckets, drums, or truck sized "totes" for very large roofs. This usually means that there is little to no tenant disruption when a roof is being worked on.
Before Coating can be applied, the roof must be dry for best adhesion. Coatings are typically white, black, or gray, but however, they can be tinted with pigment to provide a nice looking or color-match a building.
When using a roof sprayer, the install must ensure winds are not over 15mph, over-spray during winds can get coating on siding, windows, and even cars parked next to the building if care is not taken.
Coating can help decrease the thermal expansion of an existing roof by deflecting sun. Aggregate (right word?) non slip surface where foot traffic is expected. Metal or electronic mil-gauges can be used to ensure coatings is being applied to the thickness required by the coating manufacturer.
Why Have a Roof Coating done?
Cost Savings of a typical Roof Replacement
Little to no Tenant Disruption
UV Reflectivity lowers energy costs
Project Length is shorter than a tear off
Additional layer of protection in addition to existing roof layers
