Slate Roof Repair Cranford, NJ
Most slate roofs in Cranford 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) 562-6887 to reach a local roofer who works on slate.
On a slate roof, the stone is usually the last thing to fail. Hard slate can last well over a hundred years and soft slate somewhat less, but in both cases the nails, flashing and valleys often wear out first. 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. Slate breaks easily underfoot and is slippery, which is why slate work is done from ladders and brackets rather than on foot. From the ground, binoculars show slipped slates, missing pieces and rusted flashing well enough to describe on the phone.
Depending on what the roofer finds, slate roof repair in Cranford, NJ can go hand in hand with slate roof replacement and slate roof installation.

How slate roof repair works
Slate repair follows a careful routine.
Set safe access
The roofer sets a hook ladder over the ridge or installs roof brackets, so weight stays off the slate. Work only happens when the roof is dry, since wet slate is slick.
Find the cause
The source is pinned down first, since a slate problem and a flashing problem are fixed very differently. If many slates are slipping, it tells the roofer the nails are failing roof wide.
Remove broken slate
A slate ripper slides under the broken slate, hooks each nail and cuts it so the slate slides out without disturbing its neighbors. 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.
Renew the metal
Valleys and wall flashings that have rusted through are replaced with new metal, with the slates carefully removed and relaid. Copper flashing is common on slate because its service life comes close to that of the stone.

Slate Roof Inspection Cranford, 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. Hard slate in good condition rings when tapped, while worn soft slate sounds dull and breaks easily.
For a slate roof inspection in Cranford, much of the surface can be checked from a ladder, with binoculars and with drone footage, so the stone is not walked on. The attic is checked as well for stains, daylight and rotted sheathing boards. 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 Cranford, NJ
Not every roofer works on slate, and the wrong repair can do more harm than the original problem. 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.
For Cranford 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. One call to (908) 562-6887 is a good place to start.

How the weather here affects roofs around Cranford
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, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Cranford is busiest after a hard winter and before the next one.

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. The nails and flashing need attention long before the slate does. Kept up with repairs, a slate roof can serve for generations.
Why are slates sliding off my roof?
Slipped slates come from failed nails far more often than from broken stone. 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. Individual slates are rehung with hooks, but widespread slipping points to relaying the roof with copper nails.
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.
Do I need a new slate roof or just repairs?
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.
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.
