Chimney leaks are almost always flashing, not roofing. The counterflashing has pulled out of the mortar joint, or there was never a cricket built on the high…
Composite gives the look of slate or shake at a fraction of the dead load, which matters on older framing that was never sized for stone. That is the short case for synthetic…
Coating is the option that keeps an existing roof out of the landfill. If the substrate is sound, a silicone system buys another cycle for a fraction of a tear-off. That is the short…
Modified bitumen is forgiving on low-slope residential decks and on the small flat sections that so many valley homes have over a patio or addition. That is the short case for torch…
