Modified Roofing Systems & Maintenance

Modified roofing systems (also known as Modified Bitumen Roofing Systems) are updated versions of asphalt roofing systems and are usually commonly installed on commercial buildings. The difference between the two roofs is the fact that asphalt roofs had to be held down by gravel and rocks since they sat on top of the roof without actually being connected to the roof.

Modified roofing systems use the same principal as the asphalt roofs but the modifiers added to the asphalt make it a part of the roof. Modified roofing systems have become very common, even for residential buildings because they are so much better.

The importance of maintaining your modified roof

You could easily preserve the life and benefits of the roof if you adopt a regular inspection and maintenance program. With proper maintenance, the roof’s performance will advance resulting to an extended life. One of the major advantages about this type of roof is the waterproofing protection.

However, seasonal elements could leave some minor damages and if you get to them before the advance, you will be able to save your roof. In addition to that, your warranty, depending on the one you got, might require that you conduct maintenance checks regularly.

Know how the roof was installed

In order to know how and where to look for damages, you need to know how it was installed. The application can happen in one of two ways. The modifiers can be used in the asphalt then combined with fiberglass or fibers to make it stronger. These are installed as entire sheets or pieces fitting the roof and can be applied in one of four ways: cold, heat, self-adhesive or heat weldable.

Should you hire a professional roofing contractor for an inspection?

If you cannot inspect yourself, because roofs can be quite dangerous, you should call in a reputable roofing company to carry out the inspection for you. Roofing systems can be complex and will need someone who is familiar with damages and their solutions. A roofing contractor will identify problems and carry out any necessary repairs with the right materials.

What to look for during inspection

· Insulation.

· Structure.

· Drainage.

How to check for leaks or broken welds

If the roof was installed in pieces or was heat welded in separate pieces, they can come apart so check for pieces pulled up. At times with bad weather, the pieces might also come off completely and will need to be re-patched.

How to check for holes or rips

With modified roofing systems, damages can occur if objects like tree limbs fall and tear holes in them. Regardless of how tiny the hole it, it will need to be patched up before it becomes larger to avoid potential leaks. You can check around the chimney or vents for holes or rips.

How to look for curling edges

If the self-adhesive method was used while installing your modified roofing system, there is always a chance that the edges will curl and lift up. It could have been a consequence of a bad installer or strong winds and it will need to be repaired as soon as you find it because more rain or winds will just push it back further. You can call in a reputable company with experienced contractors to do the repairs for you.

How to look for blisters and ponding water

When moisture is trapped in the roof, it is known as blistering and can damage the roof if left unchecked. Sometimes it’s not even moisture but air entrapment so look for places with bubbles. Ponding water is a result of poor drainage systems and it becomes ponding water if it stands on the roof longer than 48 hours. In this case, the drainage systems will have to be checked for clogs.
