In the past, roofing for a flat surface has had a tendency to develop a leak. That undesirable feature has vanished from TPO roofing.
What is so special about the TPO-based style?
A rooftop that displays the TPO style contains a blend of polypropylene and ethylene-propylene rubber. In addition, it relies on the presence of filler, along with other substances.
The chemicals found in the filler are fiberglass and carbon. Both of those are non-toxic and non-hazardous, characteristics that those 2 substances share with the other chemicals in TPO’s blend. Moreover, there are no plasticizers in the TPO blend.
TPO’s beneficial features
• It creates a roof with a watertight surface.
• It is not expensive; it sells for around $5.50 per square foot.
• It can be installed over top of existing roofing.
• It has fewer seams than the popular EPDM system.
• All the seams have been welded in place, making them stronger than any other seam on the market.
• It is puncture-resistant.
• It displays a marked level of resistance, following introduction of a tear or abrasion.
• Effectively reflects UV rays
• Comes in a variety of colors
Owners of commercial buildings welcome the fact that the roofing market now includes the TPO style.
The strong seams in that new style of roofing work to increase the roof’s durability. As the strong seams can be found in sheets that reflect UV rays, the same sheets manage to keep the building under it cooler.
Because the sheets containing the TPO blend display a high level of resistance to punctures, tears and abrasions, they aid creation of a roof that holds up well, even if people make a habit of walking on the roof’s surface.
Some homeowners, too, have favored the protection provided by TPO roofing.
Because it comes in different colors, homeowners have the ability to match the color of the rooftop and the hue used in the trim around the home’s windows.
In addition, a homeowner has the chance to customize the home’s roof, by having fire-resistant chemicals added to the TPO-blend. In certain fire-prone areas, that feature has increased TPO’s popularity.
Repair of TPO Roofs
In most cases, a TPO roof will last nearly 15 years. As it gets worn out, the flashings get damaged, punctured membranes are and ripped seams can cause your roof to leak. Your sign is to check for leaks and the wetness patches on the walls, as it seeps into the roofing insulation. You will need to call in the roofing contractor in San Mateo to do a complete inspection and make the necessary repairs. After the initial inspection and evaluation of the roof, the contractor will be able to tell you about –
• Areas where the water is seeping in through the insulation
• Age of the TPO roof
• Multiple roof layers
• Condition of the seams
