In La Verne’s climate, we see specific types of roof damage more frequently than others. Heat damage is the biggest issue – our intense summer sun causes shingles to crack, curl, and lose granules prematurely. The UV exposure also breaks down sealants around flashing and vents, creating entry points for water.
Temperature fluctuations between our hot summers and cooler winters cause materials to expand and contract, which loosens nails and creates gaps. We also see wind damage from occasional strong winds that lift or tear off shingles, especially on older roofs where the sealant has deteriorated.
Winter rain damage is common too, particularly around chimneys, skylights, and roof valleys where water tends to collect. The combination of our dry summers followed by concentrated winter rainfall tests every seal and joint on your roof, often revealing weak spots that developed during the hot months.
