Flat roofs are common features of most commercial buildings. Their installation is often done by professional roofers who are not only experienced in flat roofing. A number of residential buildings also have flat roofing as the cover. Hiring a flat roof contractor is a sensitive matter. Caution is necessary for such an issue. Rushing through the search for the right contractor will not help at all. The contractor must have the necessary credentials. He must possess the skills and knowledge required for installing, repairing, replacing or maintaining the roof.
A good contractor knows everything about the three main types of flat roofs, which are:
Furthermore, he is knowledgeable about the cost of working on the flat roof. The good news is flat roof is cheap compared to the pitched or slope roof. The materials required to strengthen this roof include EPDM, TPO, and PVC. The cost of installation differs depending on the roofing materials used on flat roofs. PVC is probably the most expensive roofing material to install while EPDM is the cheapest. With the intervention of the contractor, you will learn that each material adds a different level of longevity of the roof, and these are:
- PVC lasts more than 30 years
- EPDM lasts 10-15 years
- TPO lasts 7-20 years
- Tar and Gravel plus Modified Bitumen last 10-20 years
Knowledgeable on Strengths and Weaknesses of Flat Roofs
Flat roofs are susceptible to leaks just like any other type of roof. The seams and flashing are the two areas the contractor is most likely to examine for leaks. The installation of PVC and TPO makes the roof incapable of allowing moisture penetration of the roof. A flat roof fitted with rolled asphalt, modified bitumen or tar and gravel is unlikely to offer the protection needed against leaks. EPDM rubber is just as susceptible due to its inability to protect the roof against moisture. The most prone parts of EPDM rubber include:
- Roof penetrations
Qualities to Look for in the Contractor
As previously stated, hiring a flat roof contractor needs a bit of work. You have to know what to look for and expect from the roofer. Many people limit their options to contractors who charge low or the cheapest rates in town. Basing the selection on pricing often leaves you with a poorly installed roof, especially if you choose roofers who charge cheap. A flat roof should last several years before it begins leaking. The contractor you choose guarantees this. Some of the qualities you should look for in the contractor include:
- High-quality roofing materials
- Licensed, insured and bonded
Experience often denotes knowledge. Nonetheless, there are times when an experienced roofer lacks the knowledge required to provide excellent services. This happens in an industry that goes through numerous significant changes all the time. Knowledge on the kind of insulation the roof needs is essential. The insulation and all its other features have to adhere to the Building Regulations. It is important to get a roofer who is registered with the right organizations as a way of guaranteeing you the much-deserved quality services.
With this information, you should be able to choose the best flat roof contractor. Moreover, this information should give you the education you need on what to expect from the roofer. Do not forget to evaluate the roofer in great details before hiring. Ask him for a list of the customers he has served in recent times. Check this information with the customers to confirm whether the roofer does what he promises. The flat roof is a special type of roof with some unique features thus deserving specialized attention.
