Our porch roof needs to be repaired. It is a flat, 8x6 roof. We received an estimate of $850 to put down some insulation board and replace the roof with a rubberized product that supposedly has a longer warranty. Since the roof is not very large, my husband and I were thinking about doing it ourselves and saving some $$. We have never done anything like this, but from what we have read it doesn't seem that bad of a project, but I would appreciate any advice. Is this a feasible project for us to undertake? Thanks!
