Airtight Construction specializes in roofing for all types of buildings - both residential and commercial buildings. We also do renovations and retrofits; a must for the Bay Area. We are your one-stop source for leak protection as we offer a wide range of services, and all deal with protecting your property from the damaging effects of water. We can reroof your property - big or small, flat roof or angled, commercial or residential. We repair siding as well, so if the water damage goes beyond just the roof, we can take care of that as well. We also offer sheetmetal services and gutters installation to help protect your existing or new construction. We also provide concrete and deck coatings to protect your sidewalks and patios from water damage. Airtight Construction also pours new concrete if your old sidewalks or patios are in need of replacement or repair.
