Roof problems can be caused by harsh weather conditions, improper ventilation, pests, and poor installation. The most common problems are leakage, blow-offs, ponding water, and roof blistering. Here at Apex Sydney Roofing, our roof repair specialists can assess your roof's condition accurately. We’ll first examine the attic by checking for signs of water damage, leakage, dark spots, holes, and places where the roof deck is already weak and drooping. Then we search the outside for any cracks, mould, missing shingles, loose chimneys, worn pipes, misaligned downspouts, blocked gutters, and improperly installed vents.
