Common roofing questions

Can commercial roofs be installed in a Massachusetts winter?

Some roofing work can proceed in winter when the selected system, weather, and site conditions allow it. Membranes, adhesives, sealants, and coatings have product-specific application and storage requirements. Ask how temperature, moisture, wind, protection of the building, and weather delays will be handled in the work plan.

How long does a commercial flat roof last?

Service life varies with the specified assembly, exposure, installation, drainage, and maintenance. Age and warranty length alone do not establish remaining life. A condition assessment can document visible deterioration, review records, identify where testing is needed, and help plan repair or replacement with stated assumptions.

Is ponding water on a flat roof normal?

Persistent standing water should be assessed for blocked drainage, slope, or other causes. Some manufacturer guidance uses 48 hours after precipitation as a reference, but conditions and requirements vary. Have a roofing professional evaluate the drainage and check the applicable system and warranty guidance; do not assume that ponding either is harmless or automatically voids coverage.

How often should a commercial roof be inspected?

Plan regular documented inspections, commonly in spring and fall, and additional checks after significant weather or rooftop work. Follow the specific roof manufacturer's maintenance instructions and warranty duties. Record findings, drainage condition, repairs, and any items that need further investigation.

What is the difference between a repair and a change order?

A repair is work to address a roof problem. A change order is a written modification to a project's agreed scope, price, or schedule, so a repair can itself be part of a change order. Agree on how additional work will be documented, priced, and authorized in the project contract, including how urgent protective work is handled.

Do you work on occupied buildings?

Occupied buildings need an access and communication plan. Work hours, staging, tenant notice, and noise-sensitive scheduling should be agreed with property management before work begins. Tell us about occupancy and site restrictions when discussing your project.

What happens if you find hidden damage during a reroof?

The contract should state how concealed conditions will be documented, evaluated, priced, and approved. Ask for unit rates or allowances where practical and a process for urgent protective work. Photos and a clear description help the owner understand the proposed change before authorizing additional work.

Does a new roof have to meet current energy code?

Roof replacement can trigger current insulation and other energy-code requirements. The applicable requirements depend on the existing assembly, the building, the project scope, and the municipality's adopted code. Repairs and recovers can be treated differently. Ask the designer or contractor to state the proposed compliance approach and confirm it with the local building department.
