Slate Roof Repair Madison, NJ
A Madison slate roofer can pull broken slates with a slate ripper, set matching replacements and repair the copper flashing that keeps the roof dry. Dial (862) 431-0046 to talk with a local roofer about the repair.
On a slate roof, the stone is usually the last thing to fail. The nails that hang each slate and the metal at valleys and walls are what wear out, long before most of the stone does. Rusted nails let slates slip loose one by one, which is why slipped slates often show up in gutters.
Slate needs repairs done with slate methods, not shingle methods. Roofers cut the hidden nails with a slate ripper, set a matching slate and fasten it with a hook or a covered copper nail. Coating slate with tar or roof cement only hides problems and stains the stone.
Look from the ground, not from the roof. Walking on slate breaks it and is dangerous when the stone is wet, so slate roofers use hook ladders and staging instead of walking the field. From the yard, note any missing or slipped slates, flaking surfaces and rusted metal at valleys or chimneys.
Many slate roof repair calls in Madison also turn up a need for slate roof replacement or slate roof installation.

Call nowThe process
The slate roof repair process
Good slate repair keeps foot traffic off the stone and leaves no exposed nails.
Rig the roof
Access is set up with ridge hook ladders and staging so nobody has to walk on the slate. Slate is never worked on while it is wet or icy.
Trace the leak
Leaks are traced back to their source, which on slate is often a valley, a flashing joint or a cluster of slipped slates. Widespread slipping points to nail failure rather than isolated damage.
Pull damaged slates
The damaged slate is freed by cutting its hidden nails with a slate ripper. The slates above stay in place the whole time.
Hang a replacement
A matching slate is fitted and secured with a hook or a covered copper nail so no fastener is exposed. Matching is easiest with salvaged slate of a similar type and age.
Repair the flashing
Corroded valley metal, step flashing and counter flashing at chimneys and walls are replaced, usually in copper, by lifting and resetting the slates around them. Copper flashing is common on slate because its service life comes close to that of the stone.
What is included

Slate Roof Inspection Madison, NJ
Before repairs, an inspection sorts out whether the slate itself is sound or nearing the end. Key checks include the slate type, how many slates are cracked or delaminating, whether nails are rusting and how worn the valleys and flashings are. Tapping a slate is a quick test: sound slate rings, worn slate thuds.
In Madison, a slate roof inspection is done mostly from ladders and with a drone so the inspector does not crack the slate checking it. Inside, the attic shows where water has gotten through and whether the board sheathing is sound. You should come away knowing whether the roof needs a repair, a section relaid or a long term replacement plan.

Slate Roofing Company Madison, NJ
Choosing a slate roofing company matters more than with most roofs, because slate needs its own tools, methods and experience. Good questions include how they remove broken slate, how they fasten replacements and how they avoid walking on the roof. Be wary of anyone who wants to tar the roof or tear off a roof with mostly sound slate at the first visit.
A slate roofing company that works in Madison should be able to describe recent slate repairs and where it sources matching slate. Salvaged slate that matches the original is the key to repairs that do not stand out. Call (862) 431-0046 to talk with a roofer who works on slate.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Madison, NJ have the roof checked in the fall and again after the snow melts.

Common questions about slate roof repair
What is the lifespan of a slate roof?
Hard slate can last well over a century, while soft slate lasts a shorter but still long span. Fasteners and flashing are what wear out first, which is why repairs keep slate roofs going so long. Kept up with repairs, a slate roof can serve for generations.
Why are slates sliding off my roof?
The nails holding each slate are the usual culprit. Older slate roofs were often hung with iron or steel nails that rust through long before the slate wears out, letting slates slide down and fall. Each slipped slate is rehung with a slate hook or covered copper nail, and if slipping is widespread, the roof may need to be stripped and relaid with new nails.
Can I walk on my slate roof?
Slate roofs should be kept free of foot traffic. Slate breaks easily underfoot and becomes dangerous when wet. Slate roofers use hook ladders and roof brackets to keep their weight off the slate, so leave the climbing to them.
Can a slate roof be repaired instead of replaced?
Slate roofs are built to be repaired one slate at a time. It is when the slate is delaminating widely, or slipping everywhere, that a full strip and relay becomes the better plan. An inspection tells you which way your roof leans.
Is roof cement a good fix for a slate roof?
Roof cement is a shortcut that tends to cause more trouble on slate. They dry out and crack, hold moisture against the slate and add work for the next repair. The lasting fix is replacing the broken slate and renewing the flashing with metal.
