Roofing & Roof Safety Anchors
Brown & Beattie Ltd. has completed assessments and designed new roofing systems for a variety of building and roof types. Expertise includes low-rise buildings such as townhome complexes with sloped and mansard roofs with experience in areas such as asphalt and cedar shingles, slate and simulated slate shingles, clay tiles, eavestroughs, soffit and fascia and attic ventilation. We have carried out many assignments with respect to the assessment of ice damming issues, successfully identifying causes and implementing solutions to minimize related occurrences.
Expertise related to flat roofing systems on both high-rise and low-rise buildings includes conventional and protected (inverted) roofing systems such as built-up roofing (tar and gravel), modified bitumen and single ply systems such as EPDM and PVC. Expertise also includes related components such as air and vapour barriers, skylights, expansion joints, flashings and drains. New roofing designs will typically include new roof insulation improving the building's thermal barrier and reducing overall energy costs. Tapered insulation can also be incorporated into the design to improve roof drainage.
Brown & Beattie has also designed and implemented several Green Roof Systems which have many benefits including lowering the building's heating and cooling costs, reducing the demand on the building and municipal storm drainage systems while doing its part to reduce the urban heat island effect and increasing green space.
Roof assessments have included the use of our state of art Thermal Imaging Camera which we have successfully used during roofing investigations to evaluate the extent of wet roofing insulation. Investigations can also include cut tests through the roofing system to evaluate concealed conditions.
Most high-rise building roofs require roof safety anchors to facilitate window washing and exterior building wall repairs. Brown & Beattie Ltd. is qualified to conduct the required annual inspections of such systems. We have our own testing equipment to test roof anchors when necessary. We have also prepared specifications for the installation of new roof safety anchors systems for some of our clients.
Case Study > Shingle Roofing Replacement
The shingle roofing at this Aurora townhome condominium complex was replaced with additional consideration for ice-damming control, which included installation of extended self-adhered waterproof sheets at the eaves and upgraded waterproofing in problem areas. Ridge vents for the attic ventilation were also replaced and 30-year architectural shingles were installed. Brown & Beattie Ltd. provided specification and tendering services along with general field review and contract administration.
Case Study > Flat Roofing Assessment
The roof replacement of this Mississauga condominium complex was phased out over multiple years based on ongoing condition assessments. Various roofing systems were used throughout the complex to accommodate site access restrictions. Brown & Beattie Ltd. prepared specifications and provided tendering, construction review and contract administration services.
Case Study > High-Rise Roofing
During the built-up roofing replacement of this Toronto apartment building, we were able to conduct test cuts and perform regular maintenance on the adjoining building while the Contractor was already on site and mobilized. This parallel work allowed the Owner to reduce their investigation costs and ensure that the roof of their adjoining building had enough serviceable life remaining to phase out replacement of the roofing.
Case Study > Shingle Roofing Assessment
A complete assessment of the roofing at this Mississauga townhome condominium complex was carried out to prioritize upcoming shingle roofing replacement. The replacement was completed in multiple phases to address the roofs which were in the poorest condition and requiring costly maintenance first. The other roofs were replaced later reducing strain on the condominium's Reserve Fund. Shingles were purchased in advance to ensure the colour and style on each block matched. Brown & Beattie Ltd. provided tendering, contract administration and construction review services during each phase.
Case Study > Podium Deck Roof Restoration
The existing single-ply rubberized roofing on the exterior recreational roof deck of this downtown Toronto condominium complex was replaced with a new 2-ply modified bitumen system as preparation for a revitalization of the roof deck area. Specifications included scheduling requirements that minimized disruption to the owner's terraces and maintained access and use to the swimming pool during the summer. Brown & Beattie Ltd. provided engineering services related to the specifications, tendering, general field review and contract administration. Structural engineering services were also provided in conjunction with the landscape architect during this project.
Case Study > Shingle Roof Replacement
The replacement of the existing deteriorated 3-tab shingles with new 40-year architectural shingles on this Rosedale area Toronto home, provides excellent long-term performance while maintaining the stately aesthetics of the neighbourhood at a reasonable cost. Brown & Beattie Ltd. provided engineering services related to field review and contract administration.
Case Study > Roof Restoration
The replacement of the existing deteriorated 3-tab shingles with new architectural shingles on this Rosedale area Toronto home, provides excellent long-term performance while maintaining the stately aesthetics of the neighbourhood at a reasonable cost. Work also included complete replacement of the sheathing, improved attic ventilation and new aluminum soffits, fascia and eavestroughs. Brown & Beattie Ltd. provided engineering services related to specifications, tendering, field review and contract administration.
Case Study > Masonry Repairs
Masonry, flashing and slate roofing repairs completed on this Rosedale area Toronto home presented the unique challenge of combining period details and elements with modern manufacturing and building science best-practices. Brown and Beattie Ltd. provided engineering services related to specifications, tendering, general field review and contract administration.
Case Study > Roof Collapse Assessment
Brown & Beattie Ltd. provided engineering services to determine the cause of this roof collapse at a produce facility in Wellington, Ontario. We additionally provided opinion regarding temporary shoring measures required to allow adjacent unaffected areas of the facility to return to full operation, while affected portions were subsequently demolished. We further provided a structural scope of work to return the building to conditions commensurate with those prior to the collapse.
Case Study > Terrace Door Replacement
The balcony terraces at this Kitchener townhouse complex are particularly prone to drifting snow. Replacement of patio doors was included in the terrace re-roofing project to take advantage of this opportunity to provide positive drainage to the exterior of the door sill assembly and to provide a continuous tie-in with the roof assembly and reduce future leakage potential. Measures were also taken to protect the wall assemblies from moisture damage related to snow build-up. Access was provided in the new wood deck for drain maintenance to reduce future maintenance difficulties. Brown & Beattie Ltd. provided specification and tendering services along with general field review and contract administration.
