Extend the life of your roof.
Preventive roof maintenance, also known as Roof Tune-ups or Roof Restorations, involve adding polyurethane sealants on flashing around chimney, heater vents, roofs jacks, and turbines. Similar to automobiles with their belts and hoses, after 8 years or so, roofing sealants made of polymers or silicone, have begun to crack and become brittle allowing water to penetrate through the vent collars into your home. Failure of these old sealants can lead to damaging(rotting) the wood deck that your shingles need to adhere to your roof effectively. In addition mold growth is a concern, not to mention the damage to walls, studs behind them, and damage to flooring as well.
Additionally, other unplanned holes in your roof are sources for water leaks. One of the causes for this is that nails after a while become exposed to the elements because the polymers have become so brittle that it has cracked off, no longer covering the nail heads. When this happens the nail head will eventually rust off causing a hole and another point for rain water access.
During the preventive maintenance/restoration/tune-up these nails are recovered with new polyurethane sealant to protect this from happening.
Tree branches that have fallen off trees are another cause of unplanned holes in your shingles.
THE COST OF TUNE-UPS IN MOST CASES RANGE FROM $1000 TO $2000 DEPENDING ON THE STEEPNESS AND THE NUMBER OF VENTS IN YOUR ROOf
for a long time and past 20 to 25 years in many cases. But these areas below are where the tune-ups focus.
Squirrels have done a number on this one and because of gap between pipe(or PVC) and lead plumbing jack, water has an access point into your home.
No gaps here. NOT vulnerable to mold, interior wall stains, or wet carpet.
The Neoprene boot has lost it's grip on the PVC pipe giving water an access to your home.
No gaps here. NOT susceptible to mold, wall or carpet stains.
If these metal covered arches are left unprotected without some kind of protection they will start rusting through and cause leaks.
But If metal is covered with rolled roofing then rusting stops. Some arches are so rusted that the metal needs to be replaced which is more costly.
Because sealant is no longer supple there is a gap where water has access to your home.
Adding new sealant assures water stays outside of home.
Hole in ridge row due to missing nail head that had previously fallen off. And a nail head about to rust off.
A nail had popped out of the flashing for apparently a long time causing a hole the size of a baseball in the wood decking.
Squirrels had been chewing the base of this plumbing collar creating a water access point
If leaves have accumulated in valleys over a long period of time moisture will eventually make it into your house because shingles will rot which creates water access points.
This is another water access point. This flashing should be flush with the shingle, not gapped as shown. The empty nail shaft hole of the pop up nail will hold water and start to rot the decking.
About once in 10 years or so this flashing needs to be resealed or unsightly leaks will appear in the wall board around fireplace.
Wood paneling on this type chimney will rot if not adequately painted and cause leaks which will usually be found around your fireplace.
This significant split in the vulnerable ridge will most likely initiate a call to the painter or a consultation with the house handyman.
These shingles are in very bad shape with large gaps and caused serious and unsightly leakage to this customers home.
