How do you know if you need Asphalt Balcony, Steps or  Mastic Asphalt Roof Repairs

So how do you know if your mastic asphalt roof, balcony or  asphalt steps need repairing? What should you look for? what kinds of damage can be caused to the asphalt? and why does it happen?

Here are some straight forward signs to look for on your Asphalt Survey:

•Bumps on the mastic asphalt surface that are raised and often rounded in shape. Visually to the eye these will appear to be obvious and unnatural in relation to rest of the flat areas. They are generally caused by trapped moisture beneath the surface of the asphalt and can be singular or multiple in number (also referred to as blows or blisters the later being in the final stages of the defects penultimate damage).

•Blisters these are often raised from the flat contours of the mastic asphalt surface circular in appearance to blows/bumps but with the top split or cracked open. To the eye these will appear to be again obvious and unnatural, not unlike small volcanos on the flat areas. They are generally caused by trapped moisture beneath the surface of the asphalt and can be singular or multiple in number.

•Cracks & Splits can be caused by trapped moisture, water seeping into a crack or split can be very damaging. In winter time rainwater in slits/cracks often turns to ice expanding the water volume and as a result pushes against the asphalt increasing the crack. This pushing can cause then wrinkles/creasing cracks or splits often also due to thermal movement in the substrate or impact damage are very clear to see.

The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.” Customer in London

“Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25m2, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryun suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.” Customer in Cambridge
