How often should a flat roof be replaced?

Flat roofs are a great choice for businesses and homes as they save time, building materials, and space, but like any roof they require replacements and repairs eventually. This likely does not come as a surprise to the owner of any structure that has a roof, but the elements that strike your roof both day and night can cause major damage over time that eventually results in the need for a replacement. Also, like angled roofs, the exterior membranes of flat roofs (the part that needs replacing) can be constructed out of a wide array of materials including EPDM, PVC, or TPO, which each have pros and cons.

Flat Roof Replacement

Flat roof replacements are usually completed in two steps by first stripping away the old roofing material and repairing any damage that may be under the old layer, and then a new layer of roofing material is added and sealed to complete the job. In description, this project sounds simple, but it is best done by professionals who can ensure your roof will last as long as possible regardless of the material.

The Nitty not-so-Gritty

Unlike pitched roofs which may be made of metal, stone, or gritty shingles, most flat roofs are covered with EPDM, PVC, or TPO. Each of these materials has strengths and weaknesses in longevity, cost, environmental efficiency, and durability. PVC is one of the most energy efficient roofing materials- it has superior UV ratings to the other two in the list, and it is very resistant to damage from fluctuating temperatures, however it is often the most expensive choice. 

EPDM is very durable and usually affordable and is often thought to be the most long-lasting flat roof material, however it is not a very green option. TPO is likely the most environmentally friendly option, and it is lightweight, and reflective which protects your roof from sun and chemical exposure. Additionally, long-lasting TPO can last for 15-20 years which is an impressive lifespan for a single ply roofing material!

Getting it Done

Roof replacements require an investment of your time and hard-earned money, but with a professional roofing service, the replacement can last for many years to come. As you are going through the process of deciding on a replacement, it is a great idea to consult with a professional to understand all your options in pricing, longevity, durability, and environmental friendliness to choose a roofing material that is best suited to your needs. After you make the decision, a flat roof replacement is not usually a very time intensive process, and many flat roof replacement projects take 2-4 days of work which is far less than any sloped roof.

Final Thoughts

Deciding to replace your flat roof does not have to be a scary or difficult process, and once you know and understand all the options available to you, it is just a simple matter of choice. Thankfully, replacing your roofing is an investment that pays off nearly instantly by increasing the curb appeal of your roof and protecting your building from all that mother nature has to offer.
