TPO stands for thermoplastic polyolefin and is a relatively inexpensive, single-ply rubber roofing material. TPO is quickly becoming one of the most popular materials for commercial roofing. TPO roofing systems comprise a single layer of synthetics and reinforcing scrim; the material is used to cover flat roofs.
TPO roofs have a number of benefits when compared to other types of roofing materials.
A TPO roof should last anywhere from 15 to 20 years. Because this material is relatively low maintenance, it should not need many (if any) repairs throughout its lifetime.
TPO roofs are made of a synthetic rubber membrane that is designed to reflect the sun’s rays and combat the heat of summer. The material also provides insulation that protects against the cold of winter.
However, the roof will last longest if it is installed in a climate where the temperatures are not too extreme. In climates with very cold winters or very hot summers, the TPO roof may not last as long as it does in a more moderate climate.
A TPO roof is repaired by patching the damaged area with a new sheet of TPO membrane. The new sheet is fastened in place with adhesive and seam tape.
If the damage is minimal, the repair can be made without disturbing the existing roofing system. If the damage is more extensive, the entire roof may need to be replaced.
TPO can be installed over an existing roof system, but it is important to ensure that the roof deck is in good condition and that there is no water damage. The TPO membrane itself is very durable and can withstand a great deal of stress, but it’s important to make sure that the roof deck is structurally sound and capable of supporting the added weight.
If you’re unsure about the condition of your roof deck or if you think there may be water damage, it’s best to consult with a professional contractor who can assess the situation and let you know what needs to be done in order to install a TPO membrane safely.
Yes, TPO roofing can be walked on, but it’s important to exercise caution. Walking on the roof can cause damage to the membrane and should only be done when necessary. If you do need to walk on the roof, use a suitable walking surface such as plywood or a plank. And always remember to wear shoes with good treads.
Yes, TPO roofing can be slippery when wet. The surface of TPO roofs is often treated with a non-slip coating to prevent people and objects from slipping off of the roof.
However, in rainy or snowy weather, the coating can become slick and cause people to fall. If you are walking on a TPO roof during bad weather, be sure to use caution and walk slowly.
TPO roofing can save you money in a number of ways.
