Tree roots, leaf fall and shade on a leafy plot
Large trees do a lot of quiet damage to a drive. Roots push up and crack a thin surface, and leaves that sit in damp shade turn to a slippery, stained layer. Moss and algae thrive where sunlight is limited, and they hold moisture against the tarmac.
If a root has already lifted a section, simply laying fresh tarmac over it will not hold. The cause needs thought: sometimes a root barrier or a different edge treatment helps, and sometimes the layout has to move a little. A careful visit before pricing avoids repeat failures. We would rather tell you what a tree is doing than cover it up.
