Roofs don’t last forever due to wear and tear of elements and eventually need re-roofing. You’ll get to a point where the cost of repairs which on older roofs continues to need fixing ends up outweighing the cost of re-roofing the whole thing. If your roof does need re-roofing don’t panic it’s not as expensive or a complex as you may think. A benefit of re-roofing for older roofs comes in the fact that modern roofs must use insulating underlay which helps retain heat in your home, so re-roofing can save you money and make your house more environmentally friendly.
