The type of materials used during the roof’s construction determines, to a large extent, the nature of any considered upgrade. Of course, certain other factors should also be taken into consideration.
Was a liquid coating used on top of an existing structure?
That is one of the ways by which a warehouse roof might be constructed. That approach works best with low-sloping roofs. The final cover for the warehouse should prove to be water resistant. However, it might lack the durability that could be found in a rooftop with an alternate material.
Did the roof’s style reflect the presence of a membrane?
There are 3 main types of membranes, and each of them has some unique characteristics. The TPO-membrane resists puncture and erosion. It features a thermoplastic polyolefin make-up. The seams and corners of the PVC-membrane show the effect of exposure to the elements. That reflects the nature of the membrane’s chief component—polyvinyl chloride. The EBDA membranes have not received the same level of study as the other choices for the typical warehouse owner.
Does the roofing contain multiple layers?
Some of the multiple layers come in rolls. Those rolls contain bitumen, and look like a roll of shingles. Others are built-up, instead of rolled and unrolled. They are more affordable than the rolled layers, but come with an increased fire risk.
Does the existing roofing contain asphalt shingles?
Those are readily available, as well as being easy to customize. Still, those benefits must be weighed against some known drawbacks. A rooftop with shingles does not last longer than 20 years. Moreover, shingles soon show the effects of any bad weather.
Could you budget for the most expensive option—metal?
Roofing contractor in San Mateo knows metal roofs last far longer than 20 years. Some have provided a building’s interior space with effective covering protection for up to 100 years. Furthermore, warehouse owners can select from among 3 different types of metals.
Steel is one of the 3 possible metals. Some steel rooftops feature a special coating. There are 2 types of coatings—aluminum and zinc. The coatings allow the roofing material to display certain characteristics, those that it normally does not possess.
A roof made with aluminum should prove more durable than one that was created from steel. Furthermore, roofers find that aluminum is easy to work with. Yet aluminum does not deliver all the benefits that have become associated with zinc roofs. A zinc roofing structure holds up well, even in a high stress environment. Zinc does not demonstrate a poor response to stresses, such as chemicals or saline in the air. Of course, like the other metals, it does not belong on a listing of the most affordable options.
