The masonry work should be performed prior to repairs to the existing roofing, unless the roof is leaking, whereupon you may need to make intermediate repairs to stop the leaking while the masonry work is performed.
Masonry work first. Best, Ken
Definitely before you do the roof, masonary work and any flashing around the chimney should be done prior to starting on the roofing.
Our recommendation would be to do the massonry work first and then roofing for a few different reasons.
1.This gives the masons freedom to step and walk on the roof without causing damage to the new shingles.
2. You will want to make sure the new flashing that is intstalled around the chimney is installed correctly, accounting for any masonry changes and is not damaged due to installation.
3. Ultimately, that the new roof is not damaged and that the warranty does not get voided.
It is always better to repair the chimney prior to any roofing work. This way the new roof doesn't get damaged.
Each case is unique but in general, the chimney should be done first. Special attention should be paid to the roof flashings around the chimney. If the flashings are behind the stone then make sure they extend far enough into the shingles so the new roof can be flashed properly. If the flashings are surface mounted and there is a counter flashing then the roofer should have no problem making the chimney base watertight

An ice and water shield is a key component of most roofing systems. Just what is ICE and water shield? It is a type of roof underlayment used in new construction and re-roofing projects. It is commonly used in leak-prone areas near eaves and in valleys. Also, it is frequently applied in problem areas like chimneys, skylights, dormers and vent pipes. Sometimes, for the ultimate in leak protection, this special membrane is installed across the entire roof.
A properly installed ice and water shield protects against the following:
Ice Dams - A Special Challenge
Recent severe winters made many Maryland property owners acutely aware of the problems posed by ice dams. Significant snow loads, combined with heat rising from living spaces, cause ice dams to form. Freezing and thawing cycles also add to the problem. Rising heat melts snow on the roof, but when the water reaches the edge of the roof, the heat source stops and the water freezes.
As this cycle repeats, ice dams can build up. Just as a lake forms behind a dam across a river, pools of water can gather behind ice dams. This standing water may migrate under roofing materials where it can cause dry rot, mold and/or mildew. The water may also migrate into the attic before staining and damaging ceilings and walls.
Installation of an effective ice and water shield is a proactive measure that can prevent expensive repairs and provide peace-of-mind.
Sometimes, severe winds in thunderstorms can create enough lift to allow heavy rain to work its way under shingles. From there, moisture can migrate down the roof until it reaches vulnerable areas. Also, heavy rain can increase flowing water to the point that it exploits vulnerable spots, especially those found in aging or improperly installed roofs.
The advantages of a high-quality ice and water shield are many:
Installation Details
In partial ice and water shield installations, existing roofing materials are removed along eaves, rake edges, valleys and other problem areas, right down to the roof deck. The self-adhering ice and water shield is then applied directly to the roof deck, and the shingles are then replaced in these areas. To ensure that one gets the full waterproofing potential out of such a product, expert installation by qualifiedroofers is important.
Leak Protection Under Metal and Shingle Roofs
Ice and water shields are a valuable addition under a wide variety of metal and shingle roofs. GAFoffers two kinds of ice and water shields - StormGuard and WeatherWatch.
StormGuard is a film-surfaced membrane that is appropriate for use under both metal and shingle roofs. It is a Good Housekeeping Seal recipient, and it is a component of the GAF Lifetime Roofing System.
WeatherWatch is a mineral-surfaced barrier that is appropriate for use under shingle roofs. It features a fiberglass-reinforced layer that resists buckling and wrinkling under shingle roofs, promoting a flatter roof. It's been awarded the Good Housekeeping Seal as well, and it is also a part of GAF's Lifetime Roofing System.
Hope this help!
Modern roofs can last three decades or more, depending on the materials used and the expertise and commitment to excellence of the contractor. Older roofs, however, aren’t quite as eternal. If you have lived in your home for a number of years and have never experienced a problem with your roof, consider yourself lucky.
However, that luck won’t last, and because of it, you may not immediately recognize a problem with your roof that might require a repair or even a new roof. Here are some signs that your roof needs attention, and if you do suspect a problem, don’t hesitate to call a professional to diagnose it and provide an estimate:
Leaks and Sunlight
Water seeping into your house is an obvious sign of a roof problem, but sometimes that leak is difficult to find, particularly if it never gets beyond your attic. Look at the attic from the inside to look for evidence of a leak and do so during the daytime—if slivers of sunlight are visible, your roof has holes that should be fixed.
Damaged Shingles
Shingles that are cracked, curling upward, cupping in the middle, or buckling or are damaged in any other way are a sign of a roof in distress. Most shingle damage, if not caused by wind, is an indication that water has seeped underneath the roof and is destroying it from underneath. A damaged shingle here and there might not be cause for alarm and can easily be replaced, but enough of them might be an indicator that you need a new roof.

Missing Shingles
Shingles can blow off during storms; if the roof is solid, you hire a contractor to replace them and move on. However, if you are losing shingles during relatively calmer conditions, something else other than a breeze might be at play. Don’t let missing shingles go unreplaced: Call a professional to fix the problem and determine the state of your roof.
Granules in the Gutter
The granules you see on asphalt shingles serve an important purpose: shielding the roof from the effects of the sun. On a new roof, excess granules may fall off the shingles—this is nothing to be concerned about. For an old roof, however, losing these granules might be a sign that the shingles are at the end (or beyond the end) of their lifespan. The sun will then beat upon your unprotected shingles and shorten the roof’s life even more. If your roof is more than 15 years old and you are seeing granules in the gutter, you may be inching closer to a replacement.
Failing Flashing
Flashing is the material that seals and protects the seams around roof features such as chimneys,skylights, and vents. If you are noticing cracking around the flashing and/or are experiencing leaks on the inside of these structures, a repair is definitely in order.
Drooping and Sagging
If your roof is visibly drooping, sagging, or depressed, a replacement roof is likely imminent. Moreover, these are also signs of potential structural damage—boards and decking in the attic might be rotting as well. Call a roofer right away to assess the damage.
The Passage of Time
Back to the conversation about luck earlier in this post: If you are not the original owner of your home but have resided in it for more than 20 years without a roof problem, you should, at the very least, be wary that the roof is on the back end of its practical life. Issues and damage can be present even in older roofs that otherwise look fine to the untrained eye. Pay careful attention to your experienced roof and consider annual inspections by a professional to help determine if there are concerns you just aren’t seeing. Also, if you live in a subdivision and your neighbors start replacing their roofs, be ready—yours might be just around the corner.

I have seen a lot of great DIY carpenter bee traps that fill up with bees. I have friends that say the traps keep them out of the house.
