Roofs represent one of the 5 main parts of a home: foundation, windows, plumbing, electrical and the roof. Preventative Maintenance is actually quite cheap, but fixing a roof that has gone to disrepair can present serious problems. Spotting problems is not always easy: even great looking shingles can hide some defects. Home inspections are advised, and hiring a good roofer is important. Call me for a referral.
