Built Up or Modified BIT Roof Maintenance Suggestions

Built up or modified BIT roofs have increased in popularity for several reasons. A single ply is elastic and durable. No gravel surfacing or coatings are required making them less costly to install and maintain. Inspections are relatively easy and leaks are easier to find and repair than with many other kinds of roofing materials. Those are the benefits typically outlined by marketers and they are true for the most part as long as you do some preventative maintenance.

 

In truth, some of the materials that are covered with granules on the surface may need to be recoated after a few years due to loss of the granules. Regular inspections will reveal this problem.

 

Unless the roofing is new, it is a good idea to find out how long ago the material was put in place and to learn about the type of material that was used. Some materials last longer than others. The inexpensive single layer asphalt-impregnated materials have a relatively short lifespan of less than 15 years. Other materials can last as long as 20 years if the weather in the area is not too severe.

 

Once you find out how long ago the BIT roof was put in and you learn about the materials that were used, you can plan for regular inspections. You can do the inspection yourself or let your roof maintenance crew handle it. Flat and low slope roofs should be inspected twice a year. Steeply sloping roofs should be inspected yearly but the drainage system should be inspected at least twice a year.

 

In most areas, inspections should be done in the spring after the harsh winter weather is over to assess any damage done by melting ice or heavy snow. The second inspection should be conducted during the fall to reduce the risk of snow damage or winter leaks.

 

In addition to assessing granule loss, there are several things to look for. Cracks and gaps between the sheets can eventually lead to leaks. It saves money to repair the cracks and close the gaps before a leak occurs. Crazing is a precursor to cracking. It might not be necessary to do a roof repair until the next inspection but it is a good idea to plan to make a repair as soon as possible.

 

Preventative maintenance will allow you to get the most out of your built-up or modified BIT roof. The time that you spend planning for and doing the inspections is time well spent.

EPDM Attributes

Colorful EPDM rubber granule feature :real raw material, non slip ,non-static ,high flexibility ,withstanding wear and tear dencay, sharp color, light gravity, strong adhesiveness ,and there is no dust and powder absorption on it and very clean. EPDM particle is a kind of high-tech chemical and environment-friendly product. As the ternary polymer made up of ethylene, propylene and a small quantity of the unconjugated, EPDM has extremely excellent features of ozone resistance, weather resistance, aging resistance and electrical insulation and outstanding color stability.
The performance of EPDM track:
1. Environment friendly: Non-toxic, nuisanceless and satisfactory.
2. All-weather use: It can keep high quality in any seasons and under any temperature difference and can be used immediately after rain.
3. Elasticity: It has proper elasticity and anti-elasticity that can decrease the consumption of physical energy and increase competition performance.
4. Absorption of impact force: It can moderately absorb the impact force of foot, decrease sports damage and is suitable for long-term exercise and competition.
5. Weather resistance: It wont fade, powder or soften due to ultraviolet, ozone and acid rain and can keep fresh color permanently
Wearing resistance: It has strong friction resistance, so it can meet the demand on long-term and high-frequency use.
6. Compressibility resistance: Its impossible that the elasticity cannot recover due to the weight of athletic equipment.
9. Resistance to impact: It has tenacious elastic layer and buffer layer. So it can absorb strong impact without any damage to the surface.
10. Flatness: The surface is flat due to the use of self-flatting material when construction. So it can meet the requirement of especially flat sports ground.
11. Strong adhesion: It can be used for special construction with strong adhesion and can prevent water rising without bubble and desquamation etc.
12. Security: It can prevent injury due to tumble.
13. Economy: It doesnt need special maintenance except current cleaning.
14. Color: The surface color is soft. The surface material of the particle can prevent the reflection of dazzling light and its beautiful and lasting.
