What are the Chimney Flashing Repair Costs in Boston?
If you’re wondering about the cost of repairing a damaged chimney flashing, the answer can vary depending on your specific situation. Minor fixes, such as sealing small cracks or patching damaged sections, are usually less intensive. However, if the flashing is significantly deteriorated and requires a full replacement, the work involved, and the cost, can increase. Several factors can influence the final price, including the extent of the damage, roof accessibility, the type of materials needed, and whether additional repairs are required.
- The age of the chimney
- The size of the chimney
- The flashing material (i.e., copper, steel, aluminum, etc.)
- The complexity of the roofing design
- The level of damage

We Repair All Types of Chimney Flashing
01

Step Flashing
Step flashing is installed around the chimney in a step-like pattern, containing different layers of shingles. We fix damaged sections and address improper installation to prevent water leaks.
02

Base Flashing
As the name suggests, the base flashing sits at the ‘base’ or bottom of the chimney, where the roof meets the vertical surface. We repair deteriorated sections to restore the flashing’s strength.
03

Counter Flashing
The purpose of counter flashing is to seal the top edge of the lower flashing components. It overlaps with the base flashing, creating a tight seal. We tighten this seal in case it’s loose or damaged.
04

Cricket Flashing
This is installed behind large chimneys that are wider in length. They divert rainwater to prevent pooling. We seal any gaps using roof cement and polyurethane caulk to maintain a watertight seal.
05

Copper Flashing
Copper is a high-end material for flashing because of its rust corrosion, but it can still rust after heavy usage. We remove oxidation to restore the flashing’s strength and reinforce its installation.
06

Galvanized Steel Flashing
Galvanized steel is a budget-friendly material for flashing, but it can corrode if it is not maintained properly. We repair salvageable metal flashing and offer a replacement if it’s beyond repair.

Our Professional Process for Installing New Flashing
STEP 01
We begin with an inspection of the existing flashing as well as the surrounding roofing materials for any signs of damage.
STEP 02
If required, we loosen the previous pieces of the flashing and also remove the shingles to prepare for the repair process.
STEP 03
We use tools like diamond blades or circular saws to create grooves in mortar joints, allowing us to add new flashing.
STEP 04
Once the new flashing has been installed properly, we secure it tightly with roof cement, caulk, nails, and a sealant.
STEP 05
If any issues are found, adjustments are made as needed. In cases where the entire flashing needs to be replaced, the scope of the work becomes more extensive.

How to Know If My Existing Flashing is Damaged?
Here’s a detailed list of the signs you need roof chimney flashing repair in Boston:
- Damp areas, water stains, or leaks near your fireplace or interior walls, especially after rain.
- Rust, corrosion, or discoloration on metallic flashing made from copper, aluminum, or steel.
- Lifted, bent, or cracked flashing. This usually means the flashing is not forming a tight seal.
