Mastic Asphalt Life Expectancy

Maintenance on any roofing product is key for life expectancy. Flat roofs especially mastic asphalt, has always been targeted as problematic. Here are some reasons why, life expectancy does not always mean problems lie with the mastic asphalt roof. Coping stones regularly occur on flat roofs, all should have a DPC under the stones to stop dampness appearing.

Many of the older flat roofs not always had a DPC so when there was a breakdown of the mortar between the stone joints, ingress would happen, thus the mastic asphalt would take the blame. Lead Flashings dressed to a mastic asphalt roof also give problems. Mortar that is pointed to the lead flashings often break down and the weight of the lead pulls from the chase, now exposing a void between the asphalt and the wall, causing ingress, the asphalt roof gets the blame.

Many new roofs have air handling units positioned around areas for air condition, tradesman work around these for maintenance unaware that oil damages asphalt, so when problems occur, mastic asphalt gets the blame. So, for we have not addressed the mastic asphalt life expectancy. These are just a few of the problem that happen during the life of a flat roof which are taken out of context. 25 years should be the minimum before any problems arise with a mastic asphalt roof. With regular maintaining annually and solar reflective painting every 3-4 years, a mastic asphalt roof will give longevity far beyond the recommended guarantee.

Heritage Asphalt Ratings

What our Customers say about our Work

“I found Heritage Asphalt by accident on the Internet. It was a video about asphalting steps. I called Ryun who was very professional and had a great deal of experience and knowledge. The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. 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
