Slate Roof Repair Lodi, NJ
A roofer in Lodi can repair a slate roof by replacing broken slates, rehanging slipped ones on copper hooks and renewing the flashing and valleys where most slate leaks start. Dial (551) 394-0610 to talk with a local roofer about the repair.
A slate roof leak rarely means the slate is worn out. 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. Coating slate with tar or roof cement only hides problems and stains the stone.
Stay off the roof yourself. Slate cracks under foot, especially older slate, and it is slick when wet or icy, so roofers work from ladders hooked over the ridge and roof brackets rather than walking on the stone. 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 Lodi, NJ can go hand in hand with slate roof replacement and slate roof installation.

The slate roof repair process
Good slate repair keeps foot traffic off the stone and leaves no exposed nails.
Set safe access
Access is set up with ridge hook ladders and staging so nobody has to walk on 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.
Pull damaged slates
A slate ripper slides under the broken slate, hooks each nail and cuts it so the slate slides out without disturbing its neighbors. The slates above stay in place the whole time.
Set new slate
A replacement slate matched in size, thickness and color is slid up into place and held with a copper or stainless slate hook. Matching is easiest with salvaged slate of a similar type and age.
Renew the metal
Worn flashing is renewed by removing the surrounding slates, installing new metal and rehanging the same slates. Copper is the traditional choice because it lasts about as long as hard slate.

Slate Roof Inspection Lodi, 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. Tapping a slate is a quick test: sound slate rings, worn slate thuds.
In Lodi, 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.

Not every roofer works on slate, and the wrong repair can do more harm than the original problem. 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. Be wary of anyone who wants to tar the roof or tear off a roof with mostly sound slate at the first visit.
For Lodi homeowners, a good sign is a slate roofer who keeps a stock of salvaged slate and talks about repair before replacement. Salvaged slate that matches the original is the key to repairs that do not stand out. One call to (551) 394-0610 is a good place to start.

How the weather here affects roofs around Lodi
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. When warm attic air melts the snow, the meltwater runs down and freezes again at the 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 Lodi, NJ have the roof checked in the fall and again after the snow melts.

Common questions about slate roof repair
Do I need a new slate roof or just repairs?
Slate roofs are built to be repaired one slate at a time. Replacement makes sense when a large share of the slate is flaking, soft or breaking, or when nails are failing across the whole roof. An inspection tells you which way your roof leans.
How long does a slate roof last?
Depending on the type of slate, a roof can last anywhere from several decades to well over a hundred years. 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.
Is roof cement a good fix for a slate roof?
Tar patches on slate fail and make proper repairs harder. They crack as they age, trap water against the stone and stain it, and they have to be scraped off before a proper repair can be done. A real repair uses new slate and new flashing instead.
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.
Why are slates sliding off my roof?
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.
