Butynol is one of the most durable flat roofing materials available. Flexible and uv resistant, it requires virtually no maintenance. However, there are a few procedures that you can take to extend its life even further. Below you will find a few tips to save you money and keep your butynol roof in top condition.
 

If your butynol is covering a deck or area that can be walked on, 1.5mm butynol should be used. This is fine for normal foot traffic, but high heels should be avoided to prevent punctures. It is also a good idea to sheath the butynol, if you plan to use garden furniture on your decking. 
  

How to clean a butynol roof.

It is good practice to clear all debris from any roof covering. Leaves and built up waste, will hold moisture on the roof and block gutters. Use a soft bristled broom to clear the waste. Take extra care around the butynol joins and flashing details. Work gently over the laps, taking care not to lift the top sheet of butynol.
In areas such as decks or lower roof coverings, the butynol may be visible from your home.  To give the butynol a better appearance, it can be cleaned with sugar soap. This will remove stains and provide a more esthetically pleasing appearance.

Stopping Butynol roof leaks, before they happen.

 
Many older butynol roof decks were secured to the structure using nails. Five inch nails were secured through the plywood at 100mm centers. With constant vibration from the Wellington wind, some of these nails may have worked loose. The nail head pops up, puncturing the butynol. Modern flat roof structures are secured with stainless steel screws. This holds the flat roof more secure and prevents punctures. The screws should be countersunk below the plywood surface.

However, there is a "work around" to solve the problem of butynol nail punctures.  If the rest of the butynol is in good condition, there is no point in re-roofing before you have to. The nails are simply driven home, (with a sheath) then a new butynol patch is secured over the top.

Periodically check all joins and lap joints. Joins are a common cause of leaks in flat roofing membranes. The top layer should be well secured and fit tight to the roofing underneath.  If one of the joins is loose, the lap joint will need to be cleaned and repaired.

Butynol staining.


After a few years on the roof, water that travels over the roof will pick up tiny dark deposits. Although this in no way affects the performance of the roof, it can lead to staining of surrounding paint work. To prevent this, I recommend you paint your flat roof membrane with an acrylic paint. This will also protect the roof from sunlight, which will extend its life even further. It will also prevent harmful deposits from entering the environment.
