Although this type of roof is supposed to last for up to fifteen years, early on we had some wind damage which shortened its lifespan. And although we had patched from time to time, we were losing the fight.
So in June we just put a new one on. From the outside there's very little visible difference. From the inside it's more obvious and for the first few weeks after the new roof was put on the scent of the fresh leaf was like new mown hay...a treat we could smell before we pulled up at the pier.
