Slate Roof Repair Kenilworth, NJ
Most slate roofs in Kenilworth that leak still have plenty of good slate, and the fix is usually new slates in a few spots and new flashing, not a new roof. Call (908) 613-5001 to reach a local roofer who works on slate.
Natural slate can last a century or more, so most slate repairs deal with what holds it on and what seals it. The nails that hang each slate and the metal at valleys and walls are what wear out, long before most of the stone does. When nails rust through, slates slide out of place and leave gaps, a problem sometimes called nail sickness.
Repairing slate the right way uses tools and materials made for it. Roofers cut the hidden nails with a slate ripper, set a matching slate and fasten it with a hook or a covered copper nail. Roof cement smeared over cracks and seams is a common bad repair that traps water and makes proper repairs harder later.
Do not climb onto a slate roof to look. 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 ground, binoculars show slipped slates, missing pieces and rusted flashing well enough to describe on the phone.
Slate Roof Repair is often paired with slate roof replacement and slate roof installation, depending on the cause.

How slate roof repair works
Here is how a slate roofer usually handles a repair.
Stage from ladders
The roofer sets a hook ladder over the ridge or installs roof brackets, so weight stays off the slate. Slate is never worked on while it is wet or icy.
Pin down the source
Leaks are traced back to their source, which on slate is often a valley, a flashing joint or a cluster of slipped slates. If many slates are slipping, it tells the roofer the nails are failing roof wide.
Remove broken slate
The damaged slate is freed by cutting its hidden nails with a slate ripper. Nothing around the repair has to come off.
Fit matching slate
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 is the traditional choice because it lasts about as long as hard slate.

Slate Roof Inspection Kenilworth, NJ
Before repairs, an inspection sorts out whether the slate itself is sound or nearing the end. It covers slate condition, nail failure, valley metal, chimney and wall flashing and any old tar repairs. Hard slate in good condition rings when tapped, while worn soft slate sounds dull and breaks easily.
In Kenilworth, 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. The result should tell you how many repairs are needed now, what can wait and how much life the slate has left.

Slate Roofing Company Kenilworth, NJ
Slate is a specialty, and a slate roofing company should show it knows the trade. Ask whether the crew uses a slate ripper, slate hooks or copper nails with bibs, hook ladders instead of walking the roof and long life flashing metal. A roofer whose first suggestion is coating the roof with tar is a red flag.
For Kenilworth homeowners, a good sign is a slate roofer who keeps a stock of salvaged slate and talks about repair before replacement. Matching size, thickness and color is what makes a repair disappear into the roof. Call (908) 613-5001 to talk with a roofer who works on slate.

What the local climate does to a roof
Cold winters bring snow, ice and a long stretch of freezing nights. 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. That is why roof repair in Kenilworth is busiest after a hard winter and before the next one.

Common questions about slate roof repair
Is it safe to walk on a slate roof?
Walking on slate is best avoided. Slate breaks easily underfoot and becomes dangerous when wet. Professionals work from ladders hooked over the ridge for this reason, and homeowners are safer looking from the ground.
Can tar be used to repair slate?
Tar and roof cement are poor fixes for 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.
What causes slates to slip?
Slipped slates come from failed nails far more often than from broken stone. Many older slate roofs used nails that corrode in time, and once a nail fails, the slate slides out of its row. Individual slates are rehung with hooks, but widespread slipping points to relaying the roof with copper nails.
What is the lifespan of a slate roof?
Depending on the type of slate, a roof can last anywhere from several decades to well over a hundred years. The nails and flashing need attention long before the slate does. With timely repairs, many slate roofs outlive several generations of owners.
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. A slate inspection shows which situation you are in.
